Thank
you.

Over the years I've heard all kinds of stories that are somewhat akin to
witchcraft.

Ni-Cad is old technology and if you are following the manufacturer's
recommendation you're likely going to get the best performance/longevity
(such as it is) and that't that.

Don't leave it in the charger beyond the standard charge time. Use it
to depletion each time before recharging and hope that the manufacturer
of your drill introduces a Li-Ion or Ni-MH replacementg
