Hello everyone, I just came back to my house to find my 6volt batteries were dead. at some point in the 3 months i was gone my battery charger died and the person watching the house never told me. so i am assuming the 6 volt batteries are 3 months dead from full charge. what is the cheapest way to charge them back up. my solar panels are packed away. is there some computer supply mod to charge them up, or charge them up 1 at a time on a 1 amp trickle controller?
