When I researched batteries for my puller, I seen a lot of negative feed back on the Optima batteries. Apparently they were bought out a few years back and have since gone down hill. I read nothing but positive things about Odyssey batteries, off-roaders with big winches love them!
Manufacturing was moved south of the border and they started using a lead/alloy combination instead of 100% lead. Need to compare the weight of an older one to the current models and you'll see what I'm talking about. A battery wholesale company I was at several years ago said that was the reason he no longer wholesaled them through his company and was selling Odyssey only..
