Man where can you go wrong by not buying an everstart Battery from Wal-Mart? That's all I've ever bought as well, until I got my new boat, but rest assured that will be the replacement Battery when I need one. By the way I'm going to install another Battery in my boat just fot the purpose of using my lights at night while night fishing. Seems if I use my Lights at night like I'm supposed to my main crankin battery gets too low to start my big motor. So I have to dig out my jumper cables and jump start my big motor. I figure the cost of an extra battery to run the lights versus the hassle of digging out the cables is worth it. Plau the cost of a ticket for not having my lights on at night while fishing is by all means worth the cost of the extra battery... Figured that if I buy one of those Solar Battery chargers, that way while it is daylight I can recharge my extra battery so it will be ready for another night fishing adventure, if I can't get back to my regular electricity...Going to have the extra battery set up on a mounted inboard battery charging bank, like the rest of my batteries... Sorry so long, I get kind of long winded at times....
