12V 60A car battery , maybe dead?
« on: February 05, 2008, 10:01:31 AM »
I have lead acid battery 12V 60A and charging 3 days with 10amp electronic charger but heating and still 10.5 volt .its dead?
is ther any way desulfating battery? pulsing device? bedini motor? thanks.
(its water level ok)

@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.

The battery should charge up to 14 volts.  A reading of 10.7 volts indicates that one cell is shorted.  A good way to diagnose this further is to look at the water level in the cells.  The shorted cell will bubble more vigorously and lose water faster than the others when it is on the charger.  As far as I know there is no way to fix a shorted cell other than a rebuild and I suppose rebuilding batteries is out of date.

Groundloop, how will wound 3 coil ? toroid or circular? i will buy parts and try your circuit  next week( maybe with  power mosfet)

Gearhead water level ok (added a little)  battery made in 2004, and 2-3 year waited without charging .

2 cells are shortet !
take an "normal" loader.

the "dead = shortet cells will not "bubble"

(Attention with fire or cigaretts) hyrogen gas . I have see on exploding from Spark on the loadin cable !!)

If you have "tabs" betwill ce cells (all 2 volts" you can find it als. also try to "burn" fre the short)

@gezgin,

Use a Cola plastic bottle and wind ALL THREE coils circular around the bottle at the same time.
When the coils are done then secure with tape and cut away exsess plastic.
Do NOT use a MOSFET!  Use a bipolar NPN power transistor. Like: 2n3055, BUX80, MJ types etc.

Best input voltage is 9 Volt.

L3 is used because it is best to have a 100% insulation between the input and the output. People
does many things like connecting wrong leads etc. Also the input diode is not needed but wil save
your circuit the day you connect the polarity wrong.

I rekomend that you build the circuit as shown for best and safest result.

Check out my new YouTube video

http://uk.youtube.com/watch?v=abJuStUv4K8

It shows what happens when you condition a "DEAD" car battery with a tiny Bedini coil.

The battery is a 12volt 60Ah Varta Blue.

Most points are explained in the video, (I think)

I hope you enjoy it

@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

I am glad you liked the video. :)

Your circuit is very similar to the Bedini SG circuit.

Does the 220nF Cap denote the frequency of the switching? Is it Tuned to the size of your coils?

When you reconditioned your dead batteries did the voltage fly all over the place like I show in my video? (Changing Impedance/de-sulfate)

One more thing; Why no core material?

Regards

Bourne

@bourne,

No, the 220nF will give some LC effect on the oscillator but the coil size dominate.
The capacitor will make the circuit self start at low voltages because the resistor
is connected to the plus rail and will charge up the cap. End result is that the circuit
will run at a voltage as low as 1 Volt.

No, it depends on the DVM you are using. The normal behavior of a Sulfated battery is that it has a high internal resistance.. So at first the voltage will go very high and then when the plates is getting cleaner the voltage will drop. At one point the internal resistance will be so low (due to cleaner plates) that the voltage will begin climbing again. When the battery has crossed the 12 Volt threshold then you can charge the battery with more current.

An air core coil is easy to make and has no expensive Ferrite or other core material.
My circuit is designed so that everybody can make it.

@ Groundloop

I Like it!  :)

I will defiantly give this a try when I get a chance. 

Seems very simple.

@ GezGin

Have you tried it yet? Hows your sickly battery doing? :)

Hi Groundloop , i have build your circuit (with two coil) short time because Bux80,bd139  very hot .(i measured frequency ~100Hz).
 and building new design with 4093 osc ~1Khz
but with this circuit needs heat sink output power diods (DSI20-12A) .battery shows 11.1 volts ,with small increasing.

@gezgin,

You must have a good heat sink on the power transistor. Please remove the BD139, it is NOT needed
for this circuit and will just make the amplification WAY to high. Can you provide a data sheet (pdf) for
the output diodes you are using?

the output diodes you are using? Also, where is the third coil L3? This coil is there so that you will NOT
couple the input direct to the output through the diode bridge. If you build the circuit as I described in my
drawing then it will work OK. The input voltage must be around 9 Volt, not 15 as you use. If the oscillator
does not run then invert the wires on the trigger side.

Sorry diod is DSEI120-12A
http://pdf1.alldatasheet.com/datasheet-pdf/view/212503/IXYS/DSEI20-12A.html
other : FEP16GT
http://www.fairchildsemi.com/pf/FE/FEP16GT.html
I used heat sink but i didnt find 500 Ohm 3.5Watt resistor(adjustable)
I found 470 Ohm/5Watt power resistor.
Groundloop, what is the time for desulphating with your circuit?
in  Japanes site talking about 4-6 week ,10KHz
Unfortunately my battery voltage drop every day 9-8-7.. maybe new one, good quality need
here scope photo (with 4093 osc)
