Battery Zapper...anybody?????
 

Can we talk about zapping those Ni-MH cells ?????
I wonder if it will makes a difference and also how to zap those cells???

Anyone built their own zapper before???

I have a home built zapper. Works great with tired cells, but obviously it can't make the cells better than new.
It consists of a diode bridge rectifier to get high voltage DC from 230 V AC, a switch that charges or discarges the capacitors, a huge bank of capacitors, a digital display to monitor the voltage of the capacitors and a thyristor that is used as a switch to discharge the energy to the cell.
