I know you are way smarter on this stuff than I am so I hesitate to even suggest this as I'm sure there is a reason you haven't considered it but just in case it might work:  a cap and a spark gap?

@ e2matrix, thankyou!

A spark gap would be too high voltage for the battery - i had considered an ignition coil - but it would solve the 'delay'requirement; simply by virtue of every spark gap being a high frequency lc tank..

So, a recovery diode off the secondary to a cap, thru a diode to another inductor - only allowed to resonate once and then the coil's magnetic field collapses, giving us anotther spike...

Or something like that, emulating what you suggested but at a lower voltage.

Thankyou again! I'll try it when i can.

@guruji,

Try a larger ceramic A.
If you use a small resistor value then use a 1 to 2 watt type.

Also try to swap the trigger coil. The oscillator will also run if the trigger coil is swapped wrong
and the bias to the transistors is set very high as you did. The resistor is just there to
give the transistor a LITTLE positive bias so that the oscillator will start to run. After that
the capacitor will AC couple the trigger coil to the emitter and keep the oscillator going.

Groundloop.

Hi Groundloop only ceramic capacitors work for oscillation other types not good?
Thanks

@guruji,

No, you can use any capacitor, but check that the capacitor can take the
voltages you will have over the trigger coil. I usually use ceramic capacitors
rated for 100 Volt. Most 50 Volt ceramics will also do fine.

Hi Groundloop that charger is amazing!!!!. It charges like hell. Ok it's comsuption is about 0.5amp but charges very fast. I've used a 1k 1/2watt resistor with a 220nf 63 mylar cap. The neon lights very bright when not charging and coil gets a bit hot but when charging everything gets normal.
I think I leave it on one coil cause it's charging more than the multicoil that I had.
Ok thanks.

hi groundloop, hope you're still subscribed to this thread.. Thankyou for all the great work you've been doing at www.energeticforum.com/renewable-energy/5699-c-o-p-1-a.html , continuing what you started doing here.

I heard about an altercation on energetic forum earth battery thread, due to which it's been mentioned on www.hereticalbuilders.com that you would be welcome there.

Thought i'd extend the welcome to you and also to any other active builders, heretics etc..

Here's how to join;

@Inquorate,

Thank you for the invitation to the www.hereticalbuilders.com and thanks
for the nice circuit you invented. I'm currently testing the circuit as a regular
charger on my desulphated batteries. It works great. The circuit runs cold
even when charging with a lot of current. No need for big heat sinks anymore.
The circuit also "tracks" the battery very good and is self regulating the current
through the charge cycle. Very little energy is wasted as heat both in the circuit
and in the battery. So it is an extremely efficient charging method.

Thanks,
Groundloop.

Hi Groundloop can you please post schematic?How did it finish about the mosfet circuit?
Thanks

@guruji,

Sure, here you go.

Use thickest possible enameled copper wire that will fit your Toroid core.
Use a small heat sink on the MOSFET transistor. Use a N-Type MOSFET
with high current capability. Any Ultra Fast diode will do instead of BYV29
as long as the diode can handle some few Ampere. Mine can take 8 Ampere.
