My motorcycle’s charging system was a little off, but it broke something in the MightMax battery and now it’s bricked and will not come back to life. Does not appear to be a way to reset it. Battery worked well up to this point. I replaced suspected faulty regulator/rectifier but the outputs on the new one appear to be near identical. So far the 2nd MightyMax battery is doing well. Hoping the first one was a fluke, but was past the return window so had to buy the 2nd one.
