Revive NiCad batteries
 

Hey guys,

I don't know if this is a repost or if it'll even work for anyone but I found it quite interesting for those of us still using NiCad packs. I did a quick search and couldn't find anything on it in the forums.

Anyone have opinions or experiences with this?

Farther down most of the people who have tried it used car batteries. It seems you need about 2-3 times the batts voltage to spike it with, so wouldn't 2 car batteries in series work best to hit batteries with?
