How long do batteries last sitting on the floor in the garage?

Yep, that’s how neighbors used to be. I lived in small town Iowa from ‘97 till ‘02. It’s a great place.

A high school friend had a 60s Mustang he used to park in such a way it was always facing a straight, down-hill area. Starter was bad and for weeks, he'd push the car from the side, get it moving and hop in and drop it in gear and start it.

Reminds me of my ex-wife that was briefly in Toyota sales in the 1990's. They would park all the non-powered manual steering cars (mainly Tercel and Corolla) on a purpose built slope decline on the lot so most potential buyers would not noticed the lack of power steering on a test drive when they drove off.

@ShadowsPapa it is hard to good neighbors these days. Heck, it can be hard to find good friends who do that these days.

I’ve had dead batteries sitting on my garage floor for decades that I keep forgetting to dispose of and they’re still there. No signs of decomposition. I think they’ll be there forever like cockroaches and those under seat McDonalds French fries you sometimes find.

I finally got around to replacing the main battery in my wife's JLR a few weeks ago, the original finally died. I disconnected the aux battery by pulling fuse 42 and disconnecting the cable. So far the battery from my JTM is doing fine.

Check their voltage then put them on a good long slow charge. Then hook a good load to them like a 12V air compressor and watch the voltage.

When it comes to Jeep batteries - two times longer than when installed.
