I put a new dual pro charger on in 04 d/t a recall on the old one. It was not a dual pro but they had bought them out. I think they were around 300 and something new 3 channel 10 amps per channel and it has never failed. I would buy one if it went out.

My question is do you guys leave your charger plugged in all the time. never have before, I would plug up and check about once a month. I'm thinking about leaving it plugged up all the time. how much would that be on the electric bill vs replacing batteries more often
