12V 60A car battery , maybe dead?

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
