I may have to go see what kind of prices Wally-World has on type 49's. I'm trying a BatteryMinder to bring my old, discharged, sulfated battery back from the dead, but I may go get another if the price is right. I don't have high hopes, since I had to add almost half a gallon of distilled water to bring the level over the plates.
I might go nuts and spend the $$$ on a Deka AGM battery....
