We have had this problem since we got this Craftsman YS4500 lawn mower, I had to clean the battery but the – terminal wasn’t even in need of cleaning, the + one had lepercy on it that was three months ago just a fairly light coating wouldn’t get shiny clean but enough to start good. Just had to clean it again today – terminal not affected just the + one. the battery is an Everstart it was made in march, 2013, I done a voltage check and its at 12.8, so my question was and is what is making it do this? Mower only has 241 hours on it I asked the Sears guy and they didn’t know either, but I think the batter is near the end of its life cause my Diehard in my 300 doesn’t even have a spot on it. Solenoid connection and starter connections don’t have a spot on em. I’m beginning to think Everstart lwn mower batteries are defective.
