12V 60A car battery , maybe dead?

@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.

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.

[Hope]

KKKKKK,   i got this one guys.     A normal 850 amp CAR batt
