Do you know if this circuit will work for lead acid gel cells too?
Or is this what most of you are using? 

Also looking at the circuit, it looks like it is just a pulse charging device.
So couldn't we just use a 555 timer set at the right freq. to get the same results?
Any large inductor could function as a source of voltage spikes.

555 timers are a lot cheaper then 600 ft of wire.

@Hhx,

I have not tried to use a toroid core on my pulse charger.
I wanted to make the charger as simple as possible while
at the same time powerfull enough to charge bigger batteries.
I have found that by using an air core I get much better
"high voltage spikes" for desulphating purposes. My charger
works as described in my drawing. If you want to try out Ferrite
or soft Iron cores, please do so but I can not give you any coil
data because I have not tried that on this circuit. If you use
a straight Ferrite rod 100 mm long and 10 mm thick, then my best
guess will be that you will need approx. 190 turns of 0,8 mm magnet
wire trifilar wound for all three coils.

I have not seen your circuit before.
Where do you connect the charge battery?


@AbbaRue

I know that my charger (the circuit is on page one in this thread) will
charge lead acid gel cells without problems.

Hi all 

@AbbaRue 
Indeed the simplicity in the coil in front of the 555 is interesting. But I believe that the groundloop circuit is better, protected against reversal and isolated out. It would be interesting to be able to contrast them. 
 
@Groundloop 
Thank you for your advice. The circuit feeds of the own battery, we understand that it stores something of load. If it is completely discharged or it is used during more time it is necessary to connect him an external charger (about 2 Amps) to maintain the circuit. 
I will see if I start it, although I am much slower, you are a crack.   
Nevertheless I worry about the confirmation of the circuit, and I would like to compare the results with the two types of coils. 
 
This is the complete source:

Another interesting link:

Sorry, my english is very poor.

@Hhx,

Your English is good enough for me. :-)

Now I understand the circuit you posted. It is an de-sulphate circuit. It draws the power needed
to operate the circuit from the connected battery.

The main difference between your posted circuit and my circuit is that my circuit also charge the connected battery. The circuit will charge the battery regardless of the battery status. If the battery is not short circuit between the plates then my charger will work.

Now, if you connect a heavy (low voltage) sulphated battery then the battery voltage will behave as shown in the attached drawing. Personally I think that a combined de-sulphate and charger is a better choice because you get a fully renewed battery when done.

@Groundloop

Thanks very much for your work on this. I now have the parts, although I am using a Bu208A for the main transistor, it has very similar characteristics to the BUX80, but 700V @ 8Ampere ultrafast switching. I also did not have enough money to buy enough 18 gauge wire (1mm) so I will need to use 23gauge for the other windings.

I should have this built this week.

Thanks again,

Tad

@UncleFester,

The BU208A is a excellent transistor for this charger. It can take the high voltage "spikes" without any harm to
the transistor. As I said in a earlier post, you can use a Ferrite rod (great source is in old defect PC power supplies)
as a core and then save a lot of magnet wire. With a Ferrite rod you can also use thinner wire. That said, the air core has proved itself as a simple and easy way to build this charger. The air core coil also has "better" properties when charging, than a Ferrite or Iron core. Please use the 18 gauge (1mm) for the main coil going to the transistor collector and use the 23 gauge (0,6mm) for the trigger coil. If you have enough 23 gauge then just use two in parallel for the output coil.
If you want to save money then you can omit the variable resistor and just use one fixed value (approx. 470 ohm 5W) resistor going from plus to the trigger coil. If you use a lab supply at the input then you can adjust the input voltage to suit your output needs.

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.

@Groundloop

Thanks for the input. Last question:

Can I use a normal wire spool of 30mm Inside diameter or is this too small? (I guess it's similar to the Bedini coil forms)

Thanks,

Tad

@UncleFester,

No.

You will need a spol with approx. 100 mm diameter.

@UncleFester,

So, did you get it to work? Is the circuit restoring old batteries?

I have more wire coming this next week and the circuit portion is already soldered onto a circuit board. So almost done = )

Thanks,

@bourne,

Thank you for that cool video on YouTube. Yes a Bedini motor will remove the Sulfate from the battery plates.
But so will a solid state "high voltage pulse" charger do, just faster and better. The battery will recover
faster with a solid state charger because the solid state has a much higher frequency than a motor charger.
I have recovered several of my "dead" batteries with my solid state charger. The only thing the charger can't fix
is shorted battery cells.

Groundloop.

A  simple   pulsed DC charger  will  work too.
I made one  from  a diode bridge and  4 1 farad  caps.
The  caps are rated at 250 V

More caps or larger caps could be sued but in  general  reconditioning the batttery  should be done at a low enough power  to not make any  bubbles.

@gezgin,

Yes there are.

Attached is a circuit diagram of a lead acid battery charger that will fix your battery.

It will NOT fix the battery if the plates inside the battery is shorted out!

If you can't solder yoursef then ask a friend that can to help you build the circuit.

Hi Groundloop

I'm new to this forum.. but I was reading this full thread... Just a few questions. I have an ebike which is powered by 4x12v33ah batteries in series, giving me 48v. My charger is a standard charger giving 59.5v. What will be the modifications in your circuit if i have to adapt this to my scenario.
I mean I will be using this charger as the input to your circuit and the output from this circuit will be used to charge the batteries.

Ground loop
Hi,
I want to seek your comment on your circuit
 can I use the L2 with the ff setup
L2  to  +source go to   one  reverse diode In4007  connected to neg terminal of 2  parallel 500 mfarad  600 v  from neg of capacitors to the no,1  of triac  BT41
1 and 2 are with neon 110v ac   no.3  of triac output neg  for charging

L2 to collector  connected to the + side of parallel connected capacitors then out as positive terminal for output charging

Also  instead of two  i will use six parallel 2n3055  with 3 neon bulbs connected alternately

Isolated L3 is good idea since ive just burned my circuit  when i try to charge a 12v70 ah car battery with 12 v  1,2 h  source   the neon got hot and burned the rubber insulation

also   your circuit is the same as in radiant joule thief charger 06  the only difference is L3    and the resistor / var resistor connection

Hope you can help me  one unit with both fast charger  and desulfator in one

cheers

Hi Groundloop

I have a question about your circuit for the best battery charger.
What is the meaning of the directed arrow to R2 from the circuit line.
I don't have a back ground knowledge about the circuit.
But I would like to build this charger. Please help me.
Thank You.
