This circuit was designed to produce high voltage spikes to remove sulfation crystals/deposits on lead acid batteries plates. This process will result in a battery which will accept charge easier, and also have its capacity restored to a higher level.
Can i use it in 12v and 24v nicd battery from drills too?
I tried that already. The capacitor may get hotter that it should.....or
cooler. Give it a try.
can i use 220uF instead of 100uF for C4? As I have good low ESR 220uF
capacitor in hand. thanks
thanks for quick response. what is the duty cycle for your desulfator? I
have used the ferrite toroid for 220uH. the capacitor 220uF, FR diode, FET,
and the ferrite core are got hot in 10 seconds. I have measured the
inductance which decrease to 180uH. Now what should I do?
All depends on the core you use. Each one is different.Really need a meter
to measure it,
Could you put schematics to somewhere or link to schematics if it is
already in the internet
Ferrite is a bad choice. You should use an iron powder core designed for
power conversion for the 220uH coil. You can find good ones in PC power
supplies. If you use ferrite, you would need an air gap. The 1mH coil is
not that critical, since its job is just to act as a filter to keep the
power spike from going back into the capacitor. It doesn't have to store
energy like the 220uH coil.
