Re: [EVGRAY] charging a coil like a cap

Body

This is the way the circuit should be for pure back "EMF only" charging. This is what I use to charge all my AA, AAA and 9 volt batteries. No forward DC pulse with current, as in Rene's circuit. I need a large Toroidal Ferrite core to try this on large 6 or 12 VDC flooded batteries. Haven't tried that yet. But for small batteries, this has worked perfectly, batteries remain cold, and brings back almost all dead alcalines, Ni-Mh and NiCads. It's basically a joule thief but instead of taking the output from collector and emitter, as it's usually done to light LEDs, I take the output from the high spike collapsing coil.

The input power supply is a 5VDC wall power supply. The measured output voltage  across the coil is around  73 VDC, measured without charging  battery and from collector to anode of diode and a temporary cap so it can be measured correctly due to high frequency. Frequency varies from 15 Khz to around 150 Khz  or more, depending on the bias. Transistor is a standard NE-3055
