I have a Panasonic 12v (NiCads) cordless drill/driver with 2 batteries
and it seems to me that the batteries aren't holding a charge very well.
They are around 3-4 years old, lightly used. They seem to charge too
quickly. If I leave them in the charger after the charger shows them as
fully charged and let them trickle charge, will that top them up? I
haven't been doing that.

Is this a loss of capacity of the batteries? Is there some way I can
restore the capacity of the batteries? Any experience with these? Thanks
for any ideas, info, suggestions, etc.

Some chargers have a diagnostic or "tune-up" mode that may help if you
leave the batteries in for an extended time, so it's worth trying.
Unfortunately, at 3 to 4 years it would be common to see some
degradation in the performance of a nicad, regardless of how much use
they have had.
