I have the largest 56V battery, that came with my mower, and after use today it is not charging. I plugged in the charger, it did the little fan whirl and self-test, and then I placed the battery in: The indicator on the charged showed ~25%, which is typical after mowing for me, but when it just showed full green bars and did nothing. There were no error or warning lights- it just acted like it was done charging even though it hadn't done a thing. I've only used the mower about half a dozen times, and bought it back in late May. Any guidance?
