I have a battery charger for charging the 12-volt boat battery. The charger
has two settings -- 2 amps or 6 amps.

My question is, if I have the charger set at 2 amps, how long is it okay for
me to leave the charger on? My boat is in a garage at a location that I
usually only get to about once a week or so. Is it okay if the charger is
left on at the 2-amp setting for say, a week?
