Several manufacturers have slightly different warranties. Cabelas has several AGM type batteries that feature different components of the lead plates and the price varies accordingly. On occasion they run sales which give free shipping and a reduced price....the one AGM that I have heard so many complaints about is the brand (OPTIMA)that looks like a 6-pack. I have shared this info with many of my fishing friends and have almost every one of them thanked me at a later date for steering them in this direction.

Just remember to make sure your charger is proper for a AGM battery. AGM batteries are sensitive to overcharging.
