Please log in for more thread options battery question. I'm reposting it here FYI: The Sulphuric acid (H2SO4) is a liquid. Normally a battery uses a dilution of around 25% acid in water. As you discharge the battery the acid content is converted to Lead Sulphate, and regenerated as Sulphuric acid when charging. If you overcharge the water content is electrolysed to hydrogen and oxygen gases which escape (that's why they say don't charge in enclosed space). A tiny amount of the acid may be lost as spray but virtually all of it will still be in the battery, but probably absorbed in the plates and not visible. Adding water to the acid generates a lot of heat, enough to spit some back out, so add a little at a time, at arms length and wear gloves and face protection. Concentrated battery acid will take the skin off. ....so the acid was still there, just in the plates rK | ||||||||||
