Hello all had a quick question about my deep cycle and posted it in the state forum to get respones from people i trust. Before i left for Greece i tried to charge up my deep cycle battery i use for night light. It was 3/4 i would guess by what i used and heard you wanted to store it with a full charge. I just have a basic walmart battery charger i put it on for about 12 hours on the lowest charge setting came back still wasnt topped off. So i bumped it to a higher setting and let it go for a bout 7 hrs came back still wasnt done. I decided at that point i was done and had to get packed. Any ideas on why it wouldnt top off the charge?Are there special chargers i am supposed to have for my Deep cycle batterys? Any info would be greatly appreciated.
