Tried to start the M3W after 4 weeks unused, switched on off 3 times as per usual, spun for about 10 seconds and then not enough power to turn over, recharged the battery same result, recharged the battery and another old battery I had lying around connected the two 2 together and the M3W started easily. In contrast my 4/4 which has a much larger capacity battery started easily. I think it is getting time for a new M3W battery despite it being less than 3 years old and always on a battery conditioner. This is the second time this winter now it has failed to start without a lot of aggravation.
