Ok here's the deal. Last October, my jeep wouldn't crank it just kept clicking when i would turn the key, a constant click and that was it. I was told it was the battery. I went and purchased a new one and it's been cranking fine every since. Well, yesterday i went to take off (it's been sitting for 10 days) and it's doing the same thing. It will not crank just a constant clicking sound. I can jump it off with no problem but other than that it won't crank. SO, i jumped it off drove for about twenty minutes. parked it turned it off, came back out, cranked right up. came home. then a couple hours later went to go again and same thing, wouldn't crank just clicking. had to jump it off. I have a hard time believing its the battery seeing its six months old. Any ideas? I'd like to have an idea before i take it to the shop so they don't bend me over replacing crap that's perfectly fine.
