Done the research
When my batteries were going to go, I done like everyone else, ask the question??? WHICH????????
come to find out they are made by Johnson control, They make the Optama, Interstate, Diehard, Everstart, well anyway, they put a lot of brand names out there, and Wallyworld had the best warrenty and best price of all the ones I checked out. This will very from brand to brand name. But wallyworld is allover the land, so would be easy the replace. Three year free replacement, 109 month total warrenty. So I bought the biggest one that would fit the space. The battery hold down needs to be longer if you use this battery for your replacement.
just my penny's worth.
