I have already changed batteries on both my 07 Nitro and 2010 Ford Taurus Limited. Factory batteries are designed to last only 3/36 and can can cause numerous issues as they start to fail.
oh really so you think it could be the battery thanks its an 07 and never replaced battery starts good just at times it cranks for a few secounds before it starts up after use thanks for info.
Nitro Year: 2007 (1 of 91,815 sold in 07)
Nitro Model: R/T 4X4 Stone White
CAT-BACK Exhaust, CAI, Projector Head Lamps
