Is it possible to leave your battery hooked up to a charger too long? I connect regular charger to battery once a month during winter off season for 30-60 minutes. I did same yesterday afternoon and left it hooked up all night, forgot about it. Battery case slightly warm, meter on charger way down. Charger has manual and auto settings. It was on manual. Did I screw it up?

What type of battery was it?

Deep cycle, main boat 12V battery I bought last year from Complete Battery Source in Mich, looked at labeling and could not find the model number.

If it is a flooded cell lead-acid battery there is not much risk to damage from over charging, other than some water loss.

If it did lose any water, use ONLY distilled water and add only enough to just barely cover the plates in the filler hole. This is an ideal situation to use a "load tester". If any damage was done to the plates it would show almost immediately with the load tester.

Thanks - Needless worry, seems fine, actually left my car lights on yesterday and used it to jump start the car - more power than car battery it seemed.
