It sounds like you only have one pack for the drill. How flat do you
run the pack before recharging?

No. There are two supplied. Pretty flat. Usually until no more useful
work is achieved.

Thats probably why they died. Capacity and self discharge varies
from cell to cell, and by the time youre getting no more useful work,
some cells are getting reversed at high current, and they really
dont like it. Best to stop running thme as soon as they start to
fade. rather than when theyre finished fading.

I'll remember that for the next set:-) Currently in despatch at
Screwfix!

I have purchased a replacement battery for my 9.6V Bosch so I can hack
in to the cells on the old one and find out what happened there.
Just hope it isn't a charger issue!
