Dodge Nitro :Battery issues?

37049 Views 39 Replies 4 Participants Last post by  rickaren
I have been having some issues while driving the headlights flicker/dim and the radio will turn off sometimes if I say roll down 2 windows at once. I just went to auto zone and they said my alternator was fine on the test and that my battery said good but only charged to 45%

Is it most likely my battery causing these issues? Thank you

How to Prepare Your Car Battery for the Winter

Batteries are not exciting things. They store power. They make our stuff work. You have to replace or recharge them sometimes. You can get new ones almost anywhere.

Nobody thinks much about batteries. This is a funny thing since batteries are everywhere. There are probably at least a handful batteries within a 20-foot radius of you right now and you probably care about none of them. There is at least one battery in your life, however, that you should be thinking about right now, and it’s the battery in your vehicle.

“I hope someone visits me, soon,” the battery in your car says. “It’s getting cold out, winter is coming, and I could use me a little bit of lovin’ before the cold and ice show up. Why does nobody ever visit?”

Your car battery is lonely. It doesn’t ask for much. But right now, it wants you to give it a little love. After all, when the cold and snow and ice arrive, that lowly battery begins the hardest part of its year.

Do you like being late for meetings because your car won’t start? Do you like playing a game of “OMG WILL IT START TODAY?” every morning before work? Does being stranded at the airport Park-N-Fly at 3 am sound like a thing you’d enjoy? Are you a fan of inventing new swear words when you turn your car’s key, only to be met with the sound of silence?

Probably not.

We’ve compiled some tips below on how to give your battery a little TLC before and during winter so your winter doesn’t suck quite as much.

Check It: Even if your older battery has been firing up reliably all summer and fall, it could still be on the verge of failure. If that’s the case, you can expect a big letdown on the first really cold morning of the winter.

Solution? Have the battery checked. Special battery-testing equipment runs your battery through a barrage of tests and spits out a result. The result might be that your battery is perfect, fine, or totally mucked — even if it still seems to be working. Do not underestimate the speed with which a few cold starts on a few cold mornings can kill a weak battery.

For maximum peace of mind, have your car’s battery scanned before the cold weather arrives, and replace it accordingly.

Sometimes, checking your battery means taking it out of your vehicle and bringing it to a place like an auto-parts store. Many service centers can run a battery check for you in minutes without even removing the battery from your car.

“We usually check the battery condition when performing an oil change at no extra charge,” automotive service technician Paul Kennaley says. “Customers appreciate it and it takes less than a minute. Plus, it could save you a major headache on those cold winter mornings.”

Clean It: Like us humans, batteries can accumulate disgusting levels of unsightly gunk if not cleaned regularly. Because of science and chemicals, the terminals of the battery (which are the metal bits that poke out of the top or side to facilitate an electrical connection) are magnets for this sort of gunk. Mostly, visible battery gunk is made of dirt, salts, crusty yuckiness, and some byproducts of gasses formed inside of your battery as they escape near the terminals.

Pop your hood and look at the battery terminals. If you see a crystallized mess that resembles a crust of salt, then you’ll want to clean your battery terminals pronto. Not only can the accumulations be harmful to your battery and things near it, it can also cause your battery to discharge even when the vehicle isn’t’ running. If you see this sort of corrosion, chances are that your battery is slowly being drained at all times. With winter approaching, your battery needs all the help it can get — and if it’s being discharged by a buildup of semi-conductive crudsicles, you’ll need to do something about it.

Easy solution here. You’ll need a battery terminal cleaning solution (available from your favorite auto parts store), and a wire brush. Follow the instructions on the cleaner, which is typically applied after the battery cables are removed for safety. Brush the corrosion away with the wire brush to reveal shiny, clean terminals.

You’ll also want to spray some battery terminal lube onto the terminals to help fend off future buildup. If you’re doing this job yourself, be sure to reconnect the battery cables snugly, ensuring there’s a good connection. Clean and lubricate the battery cable connections, too.

If you’re not comfortable handling this maintenance on your own, ask your favorite mechanic for help, perhaps while your car is in for a pre-winter oil change.

Help It: There are a few ways you can help your battery to make its life less miserable when the weather turns cold.

First, consider the use of a trickle charger, which can be purchased on the cheap from your favorite auto parts store. You hook it up to your battery and plug it into an electrical outlet when you won’t be driving for a while. The trickle charger works to maintain a full battery charge and is a great idea to use when you won’t be driving for a few days or more — and especially if you’ve got a modern car with high-draw electronics.

Second, consider using synthetic motor oil if you don’t already, even just for the colder months. Synthetic motor oil is pricey and may be overkill for some vehicles, but using it makes it much easier for your battery to turn your engine over in extreme cold. This can help ensure your car starts every time and doesn’t kill your battery in the process.

Third tip? Use the block heater. Plug your car in when it’s going to get really cold and your engine will be toasty warm under the hood. Starting a warm engine is much easier on your battery than starting a cold one, which means a higher likelihood of cold-start success in the middle of February and less drain on your battery throughout winter.

Here’s a final tip: if you do need to jump start your car to get it started this winter, be sure to drive it a good while before turning it off again to help the battery recharge. Do not turn the engine off again until your parked at a safe location where you won’t freeze if your ride fails to restart.

The Best Booster Cables for Winter Driving

The Best Booster Cables for Winter Driving

Feb 15, 2018

There’s a bit of twisted humour in the timing of when things fail.

The furnace always calls it quits on the coldest day of the year. Air conditioning bites the dust just as the heat of the summer reaches its peak. In the same way, car batteries seem to fail in the coldest months of the year. Perhaps a smaller passenger has left an interior light on, and the battery has been drained. In both cases, starting a cold engine is a tough task. When a dead battery inevitably happens, you need a boost.

Predicting when you’ll need a boost is impossible, so it’s better to be prepared with booster cables on board. But what are some of the best things to look for when picking your booster cable? There are a lot of great options available, and most will do the trick. User ratings online can provide some indication of how good they are, and Amazon still has the best collection of user ratings online.

Consider how your booster cables will be stored. These long cables can be cumbersome if not stored well, or damage to the rubber insulation could occur. Look for cables that come with their own carrying case. This is a really easy way to keep them tucked away. Winter temperatures can make cheap rubber insulation brittle, causing booster cables to be stiff and difficult to use. More expensive cables use special compounds that endure cold weather. All weather resistance is a must, though widely available.

A good value level example is the Capri Tools CP21081 Booster Cable. This booster kit includes a carrying bag and good UL rating for all-weather performance. There are other considerations, too, like the length. At 16 feet, this is an ideal length for parking lot boosting. Cold weather boosting requires a lot of crank power. In automobiles, this is generated using a lot of current, measured as amps.

In order to accommodate this increase in electrical flow, booster cables should have bigger cables. AWG, American Wire Gauge, is a standard that helps identify how big a cable is. The smaller the number, the bigger the cable. The Cartman Booster 16-foot booster cables offer four AWG wires. These wires are ideal for high cranking vehicles and designed to endure extreme winter conditions. Larger wires also stand up to wear and tear.

Large vehicles, like full-size SUVs and trucks, produce a lot more current than smaller vehicles. Additional length is required to reach boost points. At 25 feet, the ABN Jumper Cable features low-temperature performance, and impressive 600 amp capacity through two AWG wires.

With the right booster cables, even a dead battery won’t keep you off the road for long.

Nitro Odyssey Battery


On my previous post of 10-11-2015 My MOPAR Battery Experience

Back in June 2012 after over 4 years of use I decided to replace my original equipment battery in my Nitro. Nothing was really wrong but I knew it was time.

I told my Dealership Service Advisor to install the best battery they had, for a replacement. They installed a MOPAR 72 Series part # BB034600AA (600CCA) battery at a cost of $159.95.

Fast forward to October 2015

I went out to start my very low mileage Nitro that had been parked in the garage, and to my surprise it did not start but made a strange short clicking noise before going completely dead. My first reaction was that it was a very costly to replace TIPM (Totally Integrated Power Module) Issue, since I had not had any battery issues.

I got out my battery charge and indeed the battery was completely dead so maybe it just needed to be recharged. The next day the battery did show it had been charged, but not fully? The Nitro again would not start and went completely dead again, so I left the charge on for another day.

Same issue again, so I used my Wife’s vehicle and a set of jumper cables inside the garage and to my delight my Nitro started! I then was more that sure that my new 3 years plus MOPAR battery was defective.

I have replaced numerous failed batteries over the years and nearly all went bad in the summer or fall, NOT in the winter.

I kept the vehicle running for several hours backing the vehicle outside the garage and faced it toward the street in case it would require a tow or another jump, before turning it off.

I decided to take it to my Dealership since no matter what was wrong it had to be repaired anyway and when I attempted to start it just barely started.

I drove it to the Dealership and explained that I was 99% sure it had a bad battery under warranty and left it running and told them if they shut it off it would not start! I asked and explained that if it was going to cost me more than the cost of a new battery, to diagnostic to just install a new one.

The Service Advisor looked it up and said if the battery was bad the pro-rate would be $80 to replace. She explained that if the battery was not defective there would be a labor charge so I said O.K. I left the vehicle overnight since I was told they cannot check a battery if driven in for around 45 minutes.

She called the next morning and left a message stating I was right that the battery was indeed bad and that the charges were $80.00 for a total of $120.00 including labor!

I called her back and said “what was the deal with any labor charge”? Her response was it was figured by the Chrysler Warranty Employee. I told her to recheck that, but when I went to pick up the Nitro the amount was the same. She explained that they had run this claim again and that Chrysler would not pay the labor.

In a calm voice I told her that no one in town would have charged me $160 in the first place for a battery and that Auto Zone would have checked my battery for free, charged it for free if needed, and installed a new or replacement battery for no labor charges! Do you really want to lose a long time customer for $40? The charge was removed.


I purchased a 72-month MOPAR battery that lasted about what is expected just over 3 years. The extra expense must be to cover the prorate warranty expense. I would have save I suspect If I had just purchased a 36-month battery originally and then another in three years (before it went bad) as others have suggested and forget about a long-term prorated battery.
I had stated that there seems to be no reason to purchase any expensive battery for your Nitro just replace it every 3 years and forget about any pro-rate warranty.

Well this past week without any warning I went to start my Nitro and found the battery too low to start it. It is pretty hard to run your Nitro battery down by leaving a door open on anything on since they are equipped with a factory Battery Saver Circuit that cuts the power off.

Anyway, it didn’t take 3 years for this best most expensive 72 month pro-rate MOPAR Dealer installed battery to become NOT dependable! I hooked up my dependable battery trickle charger and in 30 minutes I attempted to start my Nitro and it started just fine.

I had several appointments already planned for the day so I got my Wife’s spare key for the Nitro and decided to just leave it running all the time I was gone from home (about 3 hours). I watched where I parked to allow access in case I would need a jump if it died. As usual I found you cannot lock yourself out of a Nitro with the engine running using your remote but using your spare key and manually locking your doors, the doors can be opened using a key.

I used my original post shown above and clicked on it to find Amazon had 6 of this battery in stock (they did not carry the correct one when my Wife’s Ford needed my first ODYSSEY battery order) and receive it two days later.

Yes, maybe after charging this MOPAR battery it many have been good for a few months or a year more? I know from past experiences it could have failed again anytime and I may not have been at home! Pass on that pro-rated replacement battery too.

Nitro Battery Install

Watch Battery Replacement: 2007-2011 Dodge Nitro

The plastic mounting hold-down bracket is on the front lower of the battery and is secured with a 10MM bolt. You will need a ratchet, long extension and a 10MM socket to remove. Don’t worry about loosing this bolt since it should have a star washer holding onto this bracket. I found this bracket not secured when Dealership had installed previous battery.


You will need a 10MM wrench to disconnect the battery terminals from your old battery. Remove the positive (left side) first.
I used a battery carrier to remove the old defective battery from the Nitro.
I transferred the felt wrap from the Dealer installed MOPAR battery to the new ODYSSEY battery.

The new ODDYSSY 34-PC1500T for the Nitro is really heavy at 49.5 pounds but has a carry handle built in to it.


You will need the Date Code from the shipping box for registration plus the 14 -digit serial number. Also located on the battery.
Re-install front hold down bracket after placing new battery in your Nitro. The slots in that bracket face forward. You may need addition lighting to see.

Reattach the battery terminals starting with the positive (left) first.

Battery is already charged but I attached my trickle charger and brought it to full charge in 30 minutes or less.

Register you new ODYSSEY battery at ODYSSEY battery - Official Manufacturer's Site under the Support tab.

Hopefully your town has a free recycled drop-off site like mine to dispose of your defective old battery.

Battery issues on both cars are now in the rear-view mirror I believe with up to a 10 year service life on their battery.

Latest Technologies Affect Battery

OEM Battery Trends: How the Latest Technologies Affect Battery Sales and Service

May 18, 2018

While the latest high-tech amenities are adding numerous safety, comfort and convenience benefits to a vehicle, they also are creating more battery-related issues for vehicle owners.

J.D. Power identified the trend in its 2017 Vehicle Dependability Study. In a summary of its findings, the global consumer research company stated: “New to the top 10 list of problems reported in 2017 is battery failure. In fact, 44% more owners report a battery failure this year than in 2016. Batteries are the most frequently replaced component not related to normal wear and tear in three-year-old vehicles at 6.1% — up 1.3 percentage points from 2016.”

The increase in battery-related complaints is continuing in 2018, according to Jason Searl of Johnson Controls International plc. Battery performance is a leading source of consumer dissatisfaction with vehicles, and it has been increasing each year as vehicles become more complex.

“A shop owner can offer consumers more value by helping them choose the right battery technology for the vehicle they drive, how they drive it, and where they drive it,” says Searl, who is vice president, start-stop battery and products for Johnson Controls’ Power Solutions division.

Everything from the geographic area in which the vehicle operates to the aftermarket gadgets a consumer adds to a vehicle affects the performance of the battery installed by the original equipment manufacturer (OEM).

Searl is one of several experts who shared their perspectives on what the latest developments in battery technologies mean for independent shops. The others are John Munsell, product manager for General Motor Corp.’s ACDelco brand, and Hayley Horn, consumer insights manager for Interstate Batteries Inc.

Memory Saver (3Meter) with Alligator Clip-On 12V Car Battery

VSTM OBD II Vehicle ECU Emergency Power Supply Cable Memory Saver (3Meter) with Alligator Clip-On 12V Car Battery Cigarette Lighter Power Extension Socket

Replacing a car battery on older vehicles used to be simple!! You unhook the old battery and install the new one.

Late-model vehicles, however, rely on computers that operate everything from the stereo to the transmission. If power is lost to the computer, the settings are lost and have to reset to default. That means the vehicle may feel different when driven, and you may have to enter a security code to access the stereo.

Using this simple memory saving device when replacing your car battery will help you avoid these problems. This device can work with any 12V DC power source, including jump starter, DC 12V Lead-acid battery, or another car’s DC 12V power outlet.

Product Description and Operation:

Powered by any jump starter with a 12V outlet into an OBD II Memory Saver.

Interface connector between a 12V DC power source and vehicle's OBD II port.

Preserves vehicle codes and electronic presets.

Replacing a car battery on older vehicles used to be simple!! You unhook the old battery and install the new one. Late-model vehicles, however, rely on computers that operate everything from the stereo to the transmission. If power is lost to the computer, the settings are lost and have to reset to default. That means the vehicle may feel different when driven, and you may have to enter a security code to access the stereo. Using this simple memory saving device when replacing your car battery will help you avoid these problems.

This device can work with any 12V DC power source, including jump starter, DC 12V Lead-acid battery, or another car’s DC 12V power outlet.

As our device with 3 meter cable, it will be a convenient way, should you not have jump starter (or Lead-acid battery) on hand, and the device can also get the 12v power supply from cigarette lighter of another good car. Just insert the Cigarette lighter plug to this car and insert into 16 pin plug to the OBD port of the car you want to replace battery. And now you can replace the battery.

As typical OBD Auto Memory saver not have Anti-protection on Incorrect Polarity (AIP), so that in case a wrong polarity power input, it will probably damage your auto ECU (Electronic Control Unit). For our Newly Upgraded Version OBD Auto Memory Saver, it has been added the Safety Function of AIP; In case a power input with incorrect polarity, AIP function automatically put into effect (electric power can’t be transmitted to your car, in case wrong polarity power input); as well, led light on memory saver will not light up. So that your car ECU and other electric devices are fully under protection during a wrong power connection.

It works on any vehicle with OBDII which is 1996 and later. It is not needed or required to change your battery. It is used to keep the memory of you radio setting and other memory computer controlled devices on the vehicle (EMCU for example.) It is used as a convenience as to not erase the memory. I used it to keep my computer controlled climate control memory because one of my 3 actuators would loose its memory and go into a failed default setting after changing the battery. When it failed it would only blow air through the defrost and the GM dealer is the only way to get it calibrated again. It worked for me so i didn't have to spend money and the dealership and it also kept all my radio settings so i didn't have to reset the time and memory stations and even the radio equalizer settings.

It is very easy to use, instructions shouldn’t be necessary; plug into your OBD2 connector (typically located under the left side of dashboard) and connect the other side to a 12VDC source before disconnecting the vehicle’s battery. After the vehicle’s battery is reconnected unplug the memory saver from the 12VDC source and then unplug from the OBD2 connector. Hope this helps, good luck.

Top 10 Best Replacement Car Batteries
Don't unexpectedly get stuck on the side of the road. Get a replacement car battery that will last.

Oct 25, 2019

You don’t want to wait until the day your car doesn’t start to begin researching replacement car batteries. Eventually, your car’s battery will run out of charge and needing a replacement is part of your car’s maintenance. Generally, you will likely have to replace your car’s battery once or twice during its life, although there are products you can purchase to help maintain and extend your car’s battery life. But that’s not what this article is about—you’re likely here because you’re shopping for a replacement car battery.

There are two general types of automotive batteries: Lead-acid (regular) and Absorbed Glass Mat (AGM). Lead-acid batteries typically cost less than AGM batteries but won’t hold a charge for as long. AGM batteries, on the other hand, are designed to withstand routine draining and recharging cycles. Most modern vehicles with high-tech features such as start/stop systems now come from the factory with AGM batteries, which is why most of our recommendations on this list are AGM batteries. They may be more expensive, but they offer better long-term performance by withstanding deep discharges and are more likely to be recovered if they’ve been accidentally drained.

Batteries also come in different sizes and terminal types, so you’ll want to check your car’s manual to get the right one prior to purchasing. You may notice some of the battery models on our list are similar but with different top terminals—make sure you’re getting the one you need.

As you browse through our list, you’ll see that we’ll highlight a couple features for most of the batteries. One of them is cold cranking amps (CCA), which measures how well a battery can start your car in cold weather conditions. Another feature is reserve capacity, which is how long a battery can run if any parts of your car’s charging system fails.

For more information on the best replacement car batteries, refer to our table of contents.

Bad Voltage Regulator Symptoms

The voltage regulator in your vehicle is in charge of keeping the right amount of electrical power flowing consistently to certain parts of your car. This means if the voltage regulator is broken, the components in your electrical system might only work erratically or not at all. That’s a pretty big deal, since you definitely need your car’s lights and battery to be dependable if you want to get anywhere! So if you’re trying to get your car in good working order, checking on this major car part is a start. Here’s how to tell if the voltage regulator is bad.

Bad Voltage Regulator Symptom #1: The Battery Is Dead

There are many reasons your car’s battery might be dead, and one of them happens to be a broken voltage regulator. This is because when this part burns out, the battery will no longer charge, meaning it will eventually die. Recharging the battery will allow the car to start, but you’ll find that the battery will be dead again sooner than you might expect if the voltage regulator isn’t working correctly. So if the battery keeps going bad, it’s probably time to take your car to a repair shop to replace the voltage regulator.

Bad Voltage Regulator Symptom #2: Your Lights Are Dim

Another way you can tell the voltage regulator is bad is when the car lights keep dimming or flickering. After all, the voltage regulator is supposed to keep the power flowing to the lights, so it’s no surprise that those lights don’t work right anymore once this part goes bad. This issue can extend to your headlights, dashboard lights and even your sound system. Basically, if these components seem to be going out or don’t turn on at all, your voltage regulator may be to blame.

Bad Voltage Regulator Symptom #3: You Notice Engine Problems

A bad voltage regulator can even affect your car’s engine. For example, as this car part stops working properly, you might notice your car’s engine sputters or stalls once in a while. It might also have trouble accelerating as you drive. If you notice this issue, a replacement for your voltage regulator may be in order so you can get the smooth acceleration you’re used to.

Bad Voltage Regulator Symptom #4: The Instrument Cluster Doesn’t Work

A car’s voltage regulator is supposed to provide power to the instrument cluster. So if you notice yours isn’t working, it’s likely because the voltage regulator is broken. You might still be able to start the car, but you’ll be missing a lot of information—such as how fast you’re driving, as the speedometer won’t be working. For this reason, it’s best not to drive the car until you get the voltage regulator replaced.

Bad Voltage Regulator Symptom #5: The Voltage Regulator Readings Aren’t Accurate

If you suspect the voltage regulator isn’t working, you can test it out to see if the readings are accurate. If, after testing the voltage regulator, you notice the numbers on the gauge seem to be changing erratically, you probably need a replacement for this part. Luckily, when you get it, this and any other related issues should be resolved so you’re back to having a car you can depend on.

Of course, just noticing one or two of these symptoms doesn’t mean your voltage regulator is bad for sure. It could be another problem that presents similar symptoms, so look into other possibilities—such as signs your alternator is bad—as well if you want to get to the bottom of the issue.

How to check for and fix a battery drain in your car

How to Stop Car Battery Drains: DIY Auto There are plenty of energy-robbing devices on your car that are supposed to go to sleep when it's parked, and sometimes, not all of them go to sleep. Here's how to give them a tranquilizer. When your car battery dies once, it may be tempting to just write it off as a fluke. Batteries can die for a huge range of different reasons, and there’s always the chance that whatever went wrong won’t go wrong again. But when your car battery keeps dying over and over again, it’s a pretty safe bet that there’s an underlying problem that needs to be dealt with before you end up stranded somewhere. Why Do Car Batteries Die? The list of issues that can cause a car battery to die is so long as to approach neverending, but virtually every battery killer out there can be shoehorned into the three basic categories of battery problems, electrical system problems, and simple user error. Some of these can be dealt with at home, and others will probably require a visit to your mechanic, but there’s no way to know for sure until you roll up your sleeves and dig in. It’s also important to note that when most people talk about a battery dying repeatedly, they are talking about a situation where the vehicle won’t start after it has been parked for any length of time. If your battery seems to die while you’re driving down the road, it’s more likely that you have some type of problem with the charging system (we’ll cover that situation as well). What Causes a Car Battery to Keep Dying? Some of the most common reasons for a car battery to die repeatedly include loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the alternator can provide, and even extreme weather. Some of these problems are enough to kill a battery on their own, while others are usually coupled with a battery that is already weak or on its last legs. Headlights or dome lights left on. Headlights, or even a very dim dome light, will drain a battery dead overnight. Make sure to check for any interior lights when it's dark outside. Some headlights are designed to remain on for a while, but a malfunctioning system may leave them on permanently. Battery in weak or poor condition. A poorly maintained or weak battery may not hold a charge very well. Even small drains, like the memory function in your car radio, may kill a very weak battery. Corroded or loose battery connections. Corroded battery connections can prevent the charging system from topping off your battery when you are driving. Loose battery connections can also cause problems. Other parasitic drains in the electrical system. Parasitic drains can be difficult to find, but they are fully capable of killing batteries dead. Common drains include glove box and trunk lights that come on, or remain on, when they shouldn't. Extremely hot or cold temperatures. Hot or cold weather won't kill a battery that's new or in good shape, but a weak or old battery may fail in extreme conditions. Extremely hot or cold weather can also magnify other underlying issues. Charging system problems. If a battery seems to die when you're driving, the charging system may be at fault. Loose or stretched belts and worn tensioners can prevent an alternator from working. Checking Headlights, Dome Lights, and Other Accessories

Car batteries are designed to power headlights, dome lights, and various other accessories whenever the engine is off, but they have a very limited capacity to do so. That means if anything is left on after the engine is shut off, the battery will almost certainly die. Leaving the headlights on can kill a weak battery in the amount of time it takes you run a short errand like shopping for groceries, but even a small interior dome light can drain a battery dead overnight. So if you're dealing with a battery that goes dead over and over again, it's worth checking it out at night when it's dark out when a faint or dimmed dome light will be easier to see. Some newer vehicles are also designed to leave the headlights, dome lights, or even the radio on for a while after you shut the engine off and remove the keys. When everything is working correctly, you can walk away from a vehicle like this, and everything will shut off on a timer. If you come back half an hour or an hour later, and things like the headlights are still on, that's probably why your battery is dying.

The same thing happened to me. You should ask for help in good service because this issue could be dangerous. I was just riding with my mom and the radio kept on turning on and off. At first, I thought it’s nothing special, but then the same thing started to happen to my car and that’s when I started to worry. I went to a random service but they didn’t help much, they just tried to rip me off. I was looking for a good service for 2-3 days and couldn’t find anything decent. I ended up searching on the internet how to fix a battery and ran into and they provided me with all the information about car batteries and how they work. I’ve been reading the whole night of that website and in the morning I tied to fix the car myself, which I managed to.
Replace Your Old Jumper Cables with a Modern Portable Jump Starter
A portable jump starter will make your life much easier

By News Staff Nov 16, 2021

Hulkman Alpha 100 Feature

Own a vehicle for long enough and eventually you are going to find yourself in a situation where your battery is drained and you need a little help to get started.

Traditionally this has meant dragging out a set of jumper cables from the trunk or out from under your seat. Then you have to get another vehicle involved – one with a healthy battery – and hook up the cables to try and give your battery a boost. This is tricky at the best of times, but gets even more complicated when if it happens to be dark outside or, even worse, pouring rain.

This is why it’s possible to make a case for getting rid of your old-school jumper cables in these situations. Sure, cables have their places in certain circumstances, but modern technology has advanced to the point where small portable jump starters like the ones from the Hulkman brand pack more than enough juice to jolt even the largest engines back to life. In fact, the company’s most powerful product is rated at a stunning 32,000mAh battery capacity, made from a quartet of lithium batteries good for 8000mAh each, with a voltage of 3.7V.

Those numbers sound great, but how do they translate into the real world? Hulkman plows more than a moment’s notice into its R&D department, finding its largest offering – the Hulkman Alpha 100 – is capable of starting gasoline- or diesel-powered engines up to 10L in displacement. The latter is no mean feat, since diesel engine tend to require a healthy nudge in order to wake from the dead.

Hulkman Alpha 100 Beauty

While wide swaths of gearheads can correctly and safely attach jumper cables with ease, those new to the art – or, some of us who are simply having brain freeze at the end of a bad day – reversing the connections on old-school cables can be ruinous for vehicles and potentially dangerous for humans. Polarity (positive and negative ends of a battery) is critically important to get right, which is why Hulkman places 10 built-in protections designed for a high level of safety.

Reverse charge protection shuts down the connection if it detects the alligator clips have been connected incorrectly, while over-current and short-circuit protections ward off freak accidents. Equally important, the unit protects against overcharging and overloading so the user doesn’t accidentally ruin a battery by trying to force feed too much electricity into the thing.

Batteries, in general, don’t like the cold. That’s why Hulkman has designed smart temperature control into some of its jump starters in an effort to ward off the power-sapping tendencies of frigid temperatures. This pre-heat tech automatically warms the unit to improve battery performance when temps are detected to have dropped below 32°F. As a device, the Hulkman 100 is designed to be operable in conditions as low as -40°F, a figure far below anything at which your author is designed to operate, actually.

All the same, don’t assume these things will last forever if left unattended. Every battery is affected by self-discharge, which is not a manufacturing defect but a battery characteristic. Batteries experience greater discharge in colder conditions, such as your vehicle’s cargo area at winter time. Hulkman’s low self-discharge design enables the battery in their portable jump starters to remain charged for up to 18 months on a full charge when stowed in the recommended temperature range of 32°F to 113°F. In other words, top the thing off with electricity occasionally during the winter if you live in the rust belt, and don’t store it on the top of your dashboard in the blazing sun if Arizona is your home. When it does come time to recharge the unit, the Hulkman 100 is capable of charging to 20% (enough for one boost) from flat in just five minutes. The whole thing can be topped off in about 90 minutes.

Hulkman Alpha 100 Jump Starter

It’s also worth mentioning that Hulkman products are equipped with an easy-to-read LCD screen which displays all manner of user and operational information from state of charge to general readiness. Gone are the days when briefly tapping together the positive and negative alligator clips of the jumper cables, creating a spray of sparks in order to see if things are securely connected to a healthy battery before trying to start the dead car. These days, the jump starter will tell you, via the LCD screen, in no uncertain terms whether or not it is ready for work.

Keeping a jump starter, like one of the units from Hulkman, tucked away in the cargo area of your vehicle is a no-brainer.

Topdon’s BT100 is the top-rated product in the category and replaces the former #2 pick AB101 on our list. It works with all major battery technologies: Conventional and enhanced flooded (EFB); AGM flat plate; AGM spiral; and gel. It can perform a standard battery health test (shown), cranking, and ripple charging system test. You get both a backlit illuminated 128 x 64 LCD readout and green-yellow-red warning lights.
Testing the BT100 Car Battery Tester
We hooked up a BT100 Car Battery Tester to one of our Optima Yellow Top test batteries (note: you must connect it directly to the posts), and the display came on immediately. The opening screen shows a small voltage readout at the bottom, and then you have to select your battery technology, in this case, AGM spiral wound, from the following screen. During several rounds of testing, we noticed that the display gets sluggish in colder temperatures. Getting a battery health reading was easy. We then tried the cranking and charging system health functions in a Mazda with a flat-plate AC Delco Gold battery. The battery health ripple test requires starting the car and holding the RPM at 2,500 for five seconds, which would be a lot easier with two people. But it was possible and gave us useful information (including that wherever our short is, it’s not in the charging system). Our biggest complaint is that it must be connected to a battery for the display to work. With short leads, this could be inconvenient for trunk-mounted batteries. It’s a great battery tester for occasional use, but if we were using one a few times a week, we’d want to upgrade to either a printout or Bluetooth. We would also have liked a case or at least a storage bag with it.
The BT100 has a great 92% positive rating from over 2,000 reviews, the best weighted average in the category. Topdon’s other models of battery testers have similar 90%-plus ratings.
Topdon Warranty and Customer Service
There is a good two-year limited warranty on Topdon battery testers and a brief three-day money-back guarantee on defective items. The company also offers a loaner tool program if your tool requires repairs under warranty. There is a toll-free customer service number for Topdon’s New Jersey headquarters and a number of web forms for technical support and warranty issues. We found high-quality pdfs of user manuals as well.
  • Pros/Easy to use and read, charging and cranking testing, compatible with all 12V vehicle batteries

How to Check Your Car's Battery
Once you’ve purchased a car battery tester, it’s time to see what condition your battery is in. Most testers will come with detailed instructions on how to operate the specific device, but here are some general steps and tips to follow.
  1. Before you start to do anything, it’s always recommended to wear a pair of rubber gloves and goggles when working with your battery. Gloves and goggles will protect your hands and eyes from acid.
  2. Start by making sure the ignition of your vehicle is off and all the lights on your car are turned off.
  3. Connect the positive lead on your battery tester to the positive terminal on your battery.
  4. Connect the negative lead on your battery tester to the negative terminal on your battery.
  5. Check the voltage of your car’s battery. If it reads somewhere above 12.6 volts, then your battery is in great condition (100 percent). A voltage reading around 12.4 volts means your battery is in good condition – approximately 75 percent. A value of 12.2 volts is about 50 percent, which means readings of 12.2 volts and lower indicate a bad battery.
  6. Once you’re done checking your battery state, remove the negative terminal first. If the clamps aren’t coming off easily, you will want to use a battery terminal puller to remove them.

The ODYSSEY battery I installed in my Wife's 2010 Ford Taurus Limited way back in 2016 is being replaced today! Yes within 2 days of SEVEN YEARS OLD. Took her vehicle in for 90,000-mile Maintenace and the Service Manager said it needed to be replaced. Hopefully he is right since we have not had any issues and the car has been really dependable. Did not want to take any chances so it was replaced with Ford's best 36-month battery that was on sale. As I posted before these batteries may last 8 to 10 years, so 7 may be O.K. He could not believe ANY battery would last this long.
