That problem is because memory chip taking power only from first cell and when that cell run out of power memory chip thinks that battery is broken and blocks it. If you not inserted battery in to charger for more then 3 times you can try to take it apart and charge first battery cell from other cells and then put it to charger - some times it works.
it can be cylinder number part 25 worn out. It have pins inside it (they hold drill bid to not spin in inside of the cylinder) if you not see that pins you need new cylinder. And you must check part number 5 if it`s not worn out and of course your drill bit
