Does anyone have any advice on how to revive ni-cad drill batteries? I hate
to keep spending money on new batteries. I try to take cre of them, but they
seem to only last a year or so. Any suggestions would be appreciated. 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

Uptime lowdown on my nicad revival: It's not worth it after all.

While I got one usable battery out of the two dead batteries, the
capacity is no longer there and it goes dead in 2-3 days, with or
without use. Cell discharge rates DO have to be matched after all.

Bottom line: Find replacements or inexpensive rebuilders.
