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.

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

cheers,
Pete.
