Battery connection is poor. Have found this with heaps of my ones. Popped off charging board..complete with plastic surround. Wedged some rolled up paper on one side of battery to shim it on an angle. Had to lever battery with a flat blade screwdriver to allow gap to fit paper roll between the silicon and battery. Carefully aligned pins and put charging cap back on. I hope this helps others.. as it done my head in for ages trying to find issue.
