One of my mowers came with a Deka battery. It has outlasted 2 Walmart batteries that I have on another mower. Northern Tools has them online but do not carry them in their local store. I like the Deka battery because there aren't any vent caps and the terminals seem to stay clean and the battery has a completely flat top. Anyway, it's time for another replacement. What is the best brand for a lawn and garden battery?
