Greets All,
Been a while, looks like my old account was purged :D
I was recently reading here and saw reference to a circuit that could be employed for reconditioning old lead acid batteries (it was said of the circuit that it dealt with sulphation on the plates).
If anyone could be so kind as to point me in the proper direction for this circuit, I'll get busy recycling old scooter batts I've salvaged :D
Cheers

This is one of the original circuits.

You can convert the PFET to a more common NFET if you know about electronics.
