Was the battery left outside or very cold by any chance?  Maybe try bringing into the warmth for a while before charging.

Not by me, but I got it second-hand in spring, it worked well for a battery saw, I was pleasantly surprised, 1/4" chain is a fiddle to sharpen. Used it lots for light work, then put it away with battery left about 75% charge, 3 lights, but I left it in the saw, not sure if that's why it discharged? Looks like I'll have to have mess with it as Kram suggested, I have seen some info about kick starting it by connecting another battery to to two outside terminals for a few seconds, but I don't have another 36v battery to use, plenty of 20v! I wonder if Mark at Skyland has a simple practical solution? He is quite close to me, hopefully he'll chime in! Thanks for all the suggestions. I service / repair all my saws, but this electric stuff has a place but initial cost and the cost of batteries limits my use and of course the lack of power versus weight, I much prefer petrol for 90% of jobs.
