@GroundLoop

I use all 12V and 24V banks that I need to desulfate (550 to 2500 Amp hour). Can I modify this for 12VDC input from my solar panels or other deep cycle battery to desulfate my 2500 Amp hour 24V bank? Also would this kill my 4000watt sinewave inverter by running it on the working bank?

Thanks,

Tad

@UncleFester,

You do not need a lot of amps and voltage to de-sulphate a battery. But you need that battery to be off
you battery bank and connected directly to a pulse charger. You should NOT have any inverter connected
to a battery that is pulse charged.

Besides that, yes, this little charger will do the job even on big batteries. It will take some time though.
I have tested my pulse charger with a input of 9 Volt @ 0,6 Amp. on a 60 A/h battery and it worked good.

I have few Pb batteries that had some of its cells completly dry
I want to bring them back to life
What would be best procedure to do so?
I must try something
Thank you

@Palic,

1. Fill the dry out cells with destilled water.
2. Build pulse charger.
3. Charge battery.

If battery cells is short circuit then recycle battery at nearest station, else enjoy a "new" battery.

Groundloop, I wanted to ask you if I could
post some pictures of  "Groundloop desulfator charger" on Oupower as a project?

are you telling me that the acid is still in the cell, or on the cell, even if it's totaly dry
and that's why I should not rince the cell with destilated water and change the entire electrolite? ???

Thank you

@Palic,

I have already posted a circuit diagram of my charger in this thread. See no need to do that again.
Attached is a image of my unit. As you can see I use two transistors in parallel so that I do not need
a very big heat sink.

Now to your dry out battery cells. In most cases the battery is still good to go if the cells is NOT short circuit.
There is no need to rinse the cell with water first. Just add distilled water. The acid is STILL there but bound as lead sulphate (and lead oxide) on the plates. When you charge the battery the acid will "reappear" in the water again.

Yesterday the windings were finished, today it's going to be electronics
I have one old heat board with already two 2n3055 transistors on it,
so this info came in just the right time.
Just to be sure, I connect the basese,collectors & emiters all
with each other pair, without resistor on emiters or bases ?
I will try to put the diodes on the
same heatboard, if I can't I will use another one.

@Palic,

Yes that is correct. Collector to collector, Emitter to emitter and Base to base.

If you want to use the same heat sink for both the transistors and diodes AND
your diodes is the TO-220 devices, then REMEMBER to use insulation between
the components!  Use rubber silicone and plastic "screw bricks".

Its working  ;D
I have batteries 180Ah that have 3 cells, 6V.
Do you think I shold desulfate one by one battery, or I could conect two of them in series?
Thank you  Groundloop

@Palic,

Just charge ONE by one. Also remember that the battery will improve
over several discharge / charge cycles.

Grounloop, my first 6V battery is on the desulfator,

I have noticed that my laboratory power supply (0...32V,0...3A) gets a little bit crazy
when supling  the desulfator, voltage goes up to 80V or even over 100V , and current
is out of range, even when I setup max 2A. Now this are mesurements on my
power supply digital voltmeter and ampmeter, when using my hand Metex DMM
this is not the case . Maybe becouse the hand DMM uses 20 mesurements
and then displays the average data?
What can be done to solve this enigma? ???
What are you using as a power supply?

Thank you for your all your data and efforts to help me.
I appreciate that very much

@Palic,

I use a 0-30V 0-5A lab supply and haven't noticed any strange effects. I guess your lab supply
has a LCD panel? Mine uses LED panel. I guess the pulses from the charger is somewhat
disturbing your LCD panel. One way to avoid that is by using a big (10.000 uF) electrolytic capacitor in parallel with the output of your lab supply.

@Groundloop
Yup, you were right  :), again
33000 uF/63V electrolitic condensator made all the diference
Now I can see that I am using 5.6V and 2.0A
I have noticed no exraordinary voltage rise on battery, just normal
charging. Today I hooked up a second battery after the first one
got 6,10V in the end. Do you think that 24 hours on desulfator for 180Ah battery
is enough?
@Palic,

Just charge ONE by one. Also remember that the battery will improve
over several discharge / charge cycles.

Groundloop.
do you mean discharge / charge cycles on desulfator or on regular charger...after desulfator?

Thank you

@Palic,

Yes, 24 hours in your case is OK. When I say discharge the battery then I mean just use the battery in your normal setup. After some usage (both charge and discharge) then put the battery back on the pulse charger again for another period. This way the battery will stay as "new" for a long time. The reason is that the pulse charging has "kicked off" some of the lead sulphate covering the lead oxide. The plates gets "cleaner" and can accept charge more easy.
(This is a simplification of what is happening but good enough explanation for most of us.)

When you use the battery then do not forget to check the water level in the cells. If water level drops then add destilled water. Water and acid is the "main" motor that keeps your battery happy. The pulse charger can only give your battery a improvement if the battery is in good working order.

I glad that the capacitor solved your power supply readout problem.  :D

Hi all

This is my first post for this great forum. A while ago that I follow it and it is an invaluable source ::)

@Groundloop
I want to make this circuit (Groundlood circuit), but i have 2 questions:

1) Is it possible to use a toroid core to reduce the nº of turns (As gezgin he suggested  ) ? which the approximate equivalence would be? (I don't have enough wire) :-\

2) Other option:
(http://www.cobaltus.com/fh/12v_lead_acid_battery_desulfator.jpg)

Which their advice is?

@Palic
Feedback?

Sorry, my english is very poor.
Regards, Hhx
