I cleaned my cuboid 150w a while ago and when I tried to fire up again to heat up the coil it suddenly displayed check battery, I tried to push the battery door but i can feel that the battery is heating up so I took the battery out quickly. Only 1 battery was extremely hot, I tried to figure out what have caused the problem and so I took a small standard screw driver that was long enough and pushed down on the interior battery contact points to see them spring up and down but 1 of them were unable to spring up and down, did that cause the problem that heats up my battery? if so, is there anyway to fix it?
