Hi Groundloop I m here again I was busy for a while but  yesterday I have made my coil with #14 gauge, as you told me: !was difficult but not impossible! and I could did it this is my first trifilar coil 200 turns of #14 gauge twisted together and just waiting for the BYV29 that are on the way. I m planning to make put a 5w 1k resistor on the output circuit to avoid to damage the transistor by this way the circuit will never run without a small load to avoid high spikes. what do you think about it? I have another idea if the circuit runs so far so good as I expect I want to make five coils and five circuits connecting all outputs in series to desulphate 60v battery bank.What do you think about it? Could it be done?.
  Best regards Groundloop all your posts are well explained

Richdes,

Great job of winding the thick copper wires. One thing I did see in your pictures was some
copper wire to keep the coil together. Please use plastic strips only. Connecting a resistor
at the output (permanently) will defeat the purpose of the circuit. The main purpose of the
circuit is the high voltage spikes so that your sulphated battery connected to the output will
be fixed and the battery charged. I will highly recommend that you ALWAYS connect the
load to the circuit first, then you switch on the oscillator. If you absolutely must run the
circuit without a load, then you can use a over voltage protector in series with your resistor,
and connect the over voltage protector between the output of your circuit.
The over voltage protector must be of a value less than your transistor maximum voltage.
I recommend a over voltage protector with a voltage of 470 Volt. EPCOS has a protector
called 470 VDC 5 kA 5 A, B88069-X2010-S102. It will do the job. That said, the simplest
solution is to always connect a load before you switch on the circuit.

I do not recommend connecting five circuit outputs in series. If you desulphate a battery with
the circuit first, then you can use a regular charger later on to charge the battery.

Thank you What you see in the picture to keep the coil together
is not copper wire is thread to sew that I use between the layers of the coil when I was coiling to hold every layer and what you see in the picture is the coil enameled for that reason you saw it like a copper wire. My goal trying to put five circuits together is never use a regular charger to charge my 60v electric scooter at home instead always use the five circuits, but if you told me that is no recommended I don't do it.

Richdes,

Does your 60v electric scooter use lead acid batteries? If so, then you can desulphate and charge them all
at once if all of the batteries are in series. You only need one circuit to do that.

Yes My 60v electric scooter use lead acid sealed (AGM) batteries I can add distilled water without any trouble but you tell me that with one circuit I can desulphate five 50ah batteries in series. Do you tell me that the circuit could do the same with one or five in series?

Richdes,

Yes, I see no reason why not. Just disconnect the + wire on the battery that goes to your bike
to isolate the series batteries from the bike electronic. Then connect the circuit and add power
to the circuit. If the batteries is very sulphated, then the voltage over the batteries will go very
high at first. After that the voltage will slowly drop down to a lower voltage. After that the voltage
will slowly climb again. Stop charging on the circuit when the rest voltage is above 12 * 5 Volt and
connect to your regular charger to top charge the batteries.

EDIT: Added a typical voltage diagram when you desulphate a lead acid battery.

I would also like to repeat some safety tips. Always connect the charge battery before switching on input power. Always switch off input power before disconnecting the charge battery. Always charge in a good ventilated area. Never charge a battery without supervision. Never overcharge a battery. Always check that the battery has the correct water level. Refill with distilled water if low water level. If the battery is defect (short circuit) and all you get is a warm battery with no voltage climb then stop the charger and recycle the battery to the nearest recycle station. This charger can not repair a shorted battery cell.

My batteries aren't very sulphated they can take charge until 13.7v when the battery charger stop charging the batteries go slowly down to 12.9 v but I know that are sulfated cause they cant hold much time my scooter autonomy has been reduced to less than a half There not shorted cells cause I have a load 100 ah battery tester and the batteries pass the test every battery is ok I guess don't you think so?

        Thanks a lot again

 Excuse me Just the last question I forget to ask you this: In your experience do you think that they can recover his ah/hour power again the internal resistence are not higth on full charge is 10mohm ,11mohm,12mohm no more and the battery manual say 6mohm when where new
       Thank you

Richdes,

My best guess is that your batteries will improve on each cycle charged by the circuit.
After your drive, when the batteries is low on charge, use the circuit until the voltage
on each of your five batteries is above 12 volt. Then top charge the batteries on your
regular charger. Run your bike until the batteries is low again, and repeat. After just
a few charge/discharge cycles you will see a improvement in your batteries. Repeat
the cycles until you can't see any more improvements. Then after a few regular charge
and discharge cycles, use the circuit again.

Richdes,

Yes, that is the point of a desulphator circuit. The internal resistance in the batteries will go
down when the lead plates is cleaner. The batteries will go up in amp/hour capacity for each
discharge/charge cycle.

@ Groundloop

I'm guessing to transform the basic trifilar coil (one trigger- one  power - one inductive power collector charger)  in a (one trigger- two power ) coil.  So two bifilar power strands with a transistor each connected in parallel for more amps out.
What should be the correct circuit because I'm a novice in electronics ?
Thanks !

I just want to find what type of batteries could be desulphated. I have tried to desulphating some sealed lead acid battery and cacium lead  battery with little success. I dont know if it is the quality of the batteries that is the issue or the circuit is not good at reviving sealed batteries. I will like to know what other people experience has been.

With the sealed lead acid batteries it is a bit more difficult.
Quite often they've lost nearly all of their water due to
overcharging and in order to begin the rejuvenation process
distilled water must be added to each cell.

I've just begun rejuvenating two 12 Volt 8 Ampere Hour sealed
batteries which were dry.  I was able to pop the top covers off to
expose the valves/filler vent holes and then added about 80 cc
of distilled water/Magnesium Sulfate solution to each cell.

With electrolyte now in the cells the desulfation process started
very slowly for about three days of steady pulsing until the
sulfation started to break down - then the recovery process
accelerated quickly and the pulsing current increased
substantially as the battery voltage decreased from more than
20 Volts to about 10 Volts.

The batteries have thus far recovered about 1/3 of their capacity
which is a good start but they still need additional pulsing to
complete the desulfation.  I've been working on them now for
nearly two weeks.  Sometimes it is a slow process.

Hello Seamonkey,

Thanks for the info. But i will like to ask why you added magnesium sulphate solution.  will only distill water not do?

The one thing to watch out for is if too much lead has fallen from the plates and built-up at the bottom of any of the cells, then it can short out that cell.  At a convenient point between cycles you might tip the battery up at a low angle: say 5 to 10 degrees and let it set and check the terminal voltage from time to time.  If it drops by about one cell's worth, then the desulfation will only help for a short time as you are on the verge of permanent battery death.
