This is a simple way of making rechargeable batteries at home using alum (epsom salt) and old battery lead plates. we can also replace lead plates with copper and steel plates, but the voltage would reach only 1v then instead of 2v

Very nice young man, did not burn yourself whist trying to empty the acid from the old SLA's ? How did you empty the batteries safely?

Epsom (magnesium Sulfate) is different from alum (potassium aluminum sulfate).
