thanks for the info. I went with the evermaxx dc29. It is a deep cycle. One more question, though. It says it is a maintenance free battery, but I've read elsewhere that guys that have bought this battery (or other supposed maintenance free batteries) still remove the caps periodically to check the water (electrolytes) level. They say they still need to be refilled from time to time. But other people have said don't do this because taking off the caps will void the warranty. Do I still need to check? I had to do this on all my older batteries. Thanks again for the help.
