I've seen ads and offers that claim they can provide a proceedure to renew a cordless tool battery that no longer holds a charge. Anyone have any knowledge, or first hand expierence, with this practice?

I've not seen that ad but would also be interested in that service. Do you have a link I can check out?

I think it's a scam..
You can somewhat "renew" individual NiCad cells that are "shorted")
(reads 0 volts and won't take a charge)
It involves using a high(er) voltage spike to "remove" the crystalline short in the bad cells.
No need to disassemble battery..
It works for a while, but the cell goes bad again soon.
