Has anyone been brave enough to pay for info on how to "revive"
cordless toll batteries that no longer hold a charge?

NiCad batteries develop a "memory". If they are charged before being
fully discharged, they will ultimately sort of "think" that they should
be charged sooner than before. One way to remedy that is to *fully*
discharge the battery then charge. No idea if that's what is being done
by the device the guy is peddling.

That is bad advice.

Every now and then, it is a good idea to run the battery down to about
10%. Running it all the way down practically guarantees that at least
one of the cells will be fully discharged early and try to take a charge
in the wrong way, causing it damage.

The "memory" effect is overblown, being difficult to actually demonstrate.

DAGS for nicad memory effect...

Michael
