There is a great article in the (Oct. issue) magazine, Bass and Walleye Boats, about the 3 different type batteries. Absorbed glass mat (AGM), gel and wet cell batteries. The one thing that made my mind up to get a gel is that you don't have to take care of them. Meaning, I sometimes don't get to fish but once a month. With a wet cell you need to keep a constant charge on it to get maximum life out of the battery. With the gel, you can leave it set and it won't hurt the battery at all. Just charge it and go. If you fish alot and are going to take care of your batteries then go with the wet cell. The one thing they said is with a gel battery you need a battery charger that was designed to include gel batteries or with a gel setting. You want a gel battery between 13.8 volts and 14.1 volts. If you go over 14.1 volts it can damage it. It's a great article I learned alot. I could try and fax it to you if you want. good luck.
