wait...
stop...
WTF are you talking about???
edit: OMG I watched the vid... this guy is ____ _____ _____ ____ crazy... yes the idea(of zaping batts) is true but what he is doing is the equivalent of amputating an arm/leg with a hacksaw

IMO its not realy worth it, pick up some used 3300nimh cells, and do a few low amp cycles, then a few high amp cycles and call it good...
damn I'm tired....
