Well it was the perfect storm. I left a light on in the toy hauler. The cord to the camper electricity got unplugged. It run the two batteries down. Are they cooked? Getting ready to go to Florida. Don't want them to fail on the way down.

Did they get completely drained to the point the light you left on was completely out? How long did they sit like that? We had a few very cold nights in Michigan the last couple days. Did the batteries get well below freezing temperature during the time they were low?

Yes the light was out. Set like that for two days. I already know the answer. Thanks.

You know your batteries history, so yes, it is easier to answer your own question. A few things pertain to amount of damage, like age of batteries, prior times run down to low levels, did they freeze.

IMO, while some damage likely happened from this single event, a fresh, healthy battery can recover, and still be of service.

Charge them, then equalize them.

Sounds like you don't have LEDs yet.

If they were in good shape performing as intended beforehand, charging them back up with a smart charger would be my first move. You could have them load tested but it should be obvious if their performance is lackluster by comparison prior to this event occurring. Whether you choose to replace them now or later is your call, there are plenty of Samsclubs and Costcos on the way to Florida. Have a great time in the Sunshine state.

I would advise check your fluid if low fill to the brim with distilled water. And charge them one at a time for eight hours then check them.

With a load tester.

Dirtclods,

Only add enough distilled water to cover the plates. After the batteries are fully charged, top off, and then equalize.

Then do a load test.
