How many cells are gone?

None AFAICT. The packs seem to *self discharge* over a few days without
use.

A few charge/use cycles and they recover but having to anticipate using
a drill by the battery charge time is tedious.

Just charge the pack as much as can be, leave it a few days, then run
the drill til it fades and check out what's happening with the cells,
while the drill is running.

Umm.. There are two inaccessible cells in the *plug* part of the pack
otherwise OK. Running the drill without load is not going to draw much
current.

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.

Having discovered the cost of better quality cells, I intend to buy
another drill. I will then be *failure proofed* to the extent of 4
batteries:-)

regards and thanks to all who contributed.
