Hi all, I purchased my 2004 grand cherokee overland in November and I'm already on my 3rd NEW battery. It's seems as almost every couple of weeks it just won't start up. I've taken it to my mechanic and he changed the battery, put in new wires, checked the alternator all that. But still nothing has solved the problem. I'm not really too good with cars but I was just wondering if someone could tell me if they had the same problem or if I could have my mechanic check something else Thanks a lot

It sounds like you have a drain on the battery, when I first hooked up subwoofers in the trunk the amp drained my battery to the point where it died once or twice, are you running any after market electronics.

Re: Constantly dying
I have the same issue, battery drain with nothing draining it. I have to hook it up to the charger every other day. I'm going to try to charge it and hook it up to a battery tender before I get another battery.

The power has to be going somewhere do you have any fuse bypasses?

Re: Constantly dying
Did you check your ignition switch? You should not be able to remove the key in ACC position, if it does, several components stay powered and you drain the battery. In that case you will need a new key barrel.

Re: Constantly dying
There's a key off battery drain, with multiple suspects.
I don't have an FSM, so can't tell you what is normal range for the 2004.
It is enough you wouldn't want to leave the vehicle for months without disconnecting the battery or pulling the power off fuse.

Take a look at this, and pull the fuse and see if it resolves it.

Unless the mechanic is an electrical system professional, you might want to consider
seeing one, as there are multiple checks you would want to make as far as voltage drops to ground from the - post on the battery with and without the alternator, drops across all the ground and + voltage cables, alternator open diodes, price/quality of battery, ability of battery to hold a charge under drain conditions, etc.

Dirty wiring and grounds are almost obligatory on an older jeep... and they can be anywhere.

Re: Constantly dying
I've never found the source of mine draining, got mine hooked up to battery tender now and it's doing the trick. I'm not tryin to go through battery after battery after battery.
