I went for the Orbital Deep cycle(my car sits a lot) I was told(not sure about yours) but for my battery I need to charge it on trickle your not supposed to charge them at or above a 6amp charge only a 2amp.. That might only be for a deep cycle. I love mine, I accidently left my lights on for a week straight. Killed the battery so I took it back and they said it was 90% dead, they threw it on a charger for 6hrs and it was 100% back to life. Love it Later-T
