Topic: Inverter left on by mistake- battery damage? (Read 1329 times) previous topic - next topic

Good day. I have a 2020 Wonder MB. It has 400 watts of solar and a 2000 watt inverter. I left the inverter on by mistake for 2 days and drained dual 6 volt batteries in error. Does this permanently damage my batteries? They don’t seem to hold a charge like they used too. Please advise. Thanks in advance.

Time maybe to get a good lithium battery maybe? You can recondition them with slow 1 amp chargers but I would look on the internet how do do that. This is what I found with a quick search. Just get a cheap voltage tester to find battery voltage.

"In any case, you will have to plug in the battery and wait until it is 100% full. Then wait until it is almost empty, about 5%. Then, plug it in again and recharge it again. Repeat the procedure several times, until you get a reconditioned battery."
