desulfation of large lead acid

[pctree]

So I have 6 of these cells

GNB H1T-41

They are flooded lead calcium with 4000ah capacity and weigh over 500lbs each.

Any input on how to desulferize them ?

The link in my signature line will take you good read on deep cycle batteries.

An equalization charge is probably the most effective way to desulphate a battery.

on a battery that large get an older AC/DC buzzbox welder, set for DC and set the voltage and then measure the output voltage to meet your battery banks need and then feed it amps till it starts boiling. vent well and watch the water level.
