Charging battery ?

If you are using a regular battery charger and it is not automatic shut off and not an on board charger. You can over charge them if you are using a high amp setting. What you need to do is check the water about once a week. As long as you have water over the plates you are ok.

everything roadrunner said, make sure it is distilled water....JMO

Best bet is an on-board charger with back-feed/over charge/reverse polarity protection, imo. Easy to just plug them in and you never have to worry about over charging. The better ones direct more amps to the battery that needs them most. For the most part they are pretty affordable and easy to hook up. Good luck.
