Car seemed to be running fine, stopped at my parents and when I put the key in to leave I heard a sort of clicking that sounded like it was coming from right there where the key was, then all of my gauges wen't from one extreme to the other and the car wouldn't turn over. I jumped it and it ran for a few minutes, I turned it off and tried to turn it back on only for it to freak again and kinda turn but not come on. I looked and the battery had little to no water, so I filled it with water and then hooked the cables back up to another car to jump it. This time I let it charge for at least 15 minutes before trying to start the jeep again and this time there was no clicking or gauge freak outs but it was just a weak attempt to turn over again and then nothing. Dead. I took the cables off and then removed the battery cables from the battery in the jeep, my girlfriend noticed everytime I took the positive cable off then touched it to the battery again the gauges would freak. Do I need a new battery? Also, looking at the enging the battery is on the left side, sitting on a "tray" there are no brackets on top of it but on the right side of this tray there is a kind of plastic bracket that sits over a lip of the bottom of the battery. There's a bolt right in the middle that goes straight down, there was a ton of corrosion (looked like a golf ball over the top of the bolt) that I wiped away and I can't seem to remove it. Is there a nut on the bottom side of this tray where the bolt comes out? If so how am I suppose to access it? Tried with pliers and wrench but no luck. I'm able to turn and turn it (may have stripped) but it won't come out! Please let me know if anyone knows what this may be or how to get the battery out. Right now it's still parked! Thanks in advance! By the way, I do have an aftermarket stereo system that Best Buy installed over a year ago the instrument lights have been kinda dim when the lights are on since but I've never had any shorts or blackouts.I think on 2 or 3 different occasions over the last year the yellow check engine light would come on for about 2 days then go off by itself.
Do you

I have a 2001 Grand Cherokee Ltd and had the same problem this afternoon. The engine would tick repeatedly when trying to start it and it wouldn't turn over. A friend jumped it and I let it charge for a bit, but later it still would just tick the first time and then do nothing when trying to start it. My battery also had a pretty good amount of corrosion on it. That apparently was the problem. Just wiping off the terminal and post won't do the trick. My friend happened to have a post and terminal cleaner.

It definitely did the trick, though it did have to be jumped one last time to get it going, but after driving on it, it's doing fine restarting. Apparently sand paper on the posts and terminals works well too. Just anything to grind the lead down through the corrosion. That may not be the solution for you, but I would certainly try it before spending lots of time and money on a new battery, etc.

Actually, after leaving it overnight, it once again would not start. I took it to Autozone and had my battery tested. They told me it and the alternator were fine, but I had read that sometimes the battery tests fail for dead batteries, so I went ahead and switched out my battery for a new one and the new one worked just fine with it. As to the bracket that keeps the battery in: it requires a ratchet with a long extension on it. Other than that, there's not too easy of a way to get it out. Your best shot is probably a pair of pliers and using a screwdriver to kind of pry the battery out after you get it loosened up. Good luck!
