Own two drillmaster 18 volt drills with three batteries and two chargers.
Anyway, two of the batteries will no longer take a charge or even light up
the pilot light on the charger.

My in-law knows a lot more than most about electical things. He buys old
devices with bad ni-cads, then charges up a huge capacitor with something
about twice the battery's voltage and zaps it. he says half of them come
back as it toasts the sulfate short-circuits.
I have also seen a few cordless drills with cords attached so you clip them
to your Jeep's battery on the trail.
Its not trash until you can't figure out how to use it anymore.
