Battery going dead...

Longtime lurker here...

Seems like I read about this last year sometime, but I've had no luck finding the thread.

Battery is good, alternator is good, belt is good.

When I can drive the GT several times a month there's no problem, but if I let it set over about three weeks the battery won't have enough juice to crank the engine.

Dealer can't find a problem. Any ideas? Could this be a ground problem?

It's an 2007 SGT, 5-speed with only 48,000 miles, and lives in the garage.

Thanks,

You need to keep it on a battery tender if not using it for weeks at a time. I have my Challenger on a tender all the time when not being used.

I need to disconnect the battery my 95 Aerostar every night because I found the computer does not shut down and drains the battery. Use a meter to check how much draw you are getting after shutdown.

Seems there might be something that stays ON, something is draining the battery. 3 weeks is not a long time for the battery to drain. Have you consider your alternator, I had a similar problem. They tested the alternator and said it was good several times. Took it off and had it replaced. No issues after.

Today's cars need to be locked when not in use to shut down some of the power drainages. And get a battery tender.

Sits 3 weeks between starts and battery dying? That's normal dude. As was already said, get a tender. Or drive it more often.
