"Geeze"? Huh? It ain't a car. I can get a car battery for less than $79. But... it ain't a car. It's a Honda generator and there ain't no battery that I can find elsewhere that would fit in the space and I wouldn't wanna on accounta the charging system only works if yer runnin the generator for HOURS at a time. I run it ten to twenty minutes a week just to test it and use up gas so the gas doesn't go stale. I keep an intelligent charger on it but it has run down so much that it has a hard time when it's -20C.
