In Reply to: Lead acid battery posted by Dave BN on August 07, 2021 at 06:26:05:
The sulfuric acid in the electrolyte is the source of the problem, but the chemical reaction that is the actual problem is the creation of lead sulfate from the lead of the plates and the sulfur from the acid. This white semi-crystalline solid is electrically conductive and shorts out the the positive and negative plates across the ends of the bundles, or through deteriorating separators. The battery when fully charged has one plate of sponge lead sulfate, and the other of sponge lead. The discharged battery has both plates sulfated to near identical. The acid in the electrolyte is now nearly gone, and in fact the remaining acid is so weak that a dead battery can freeze. The battery rebuilders are few and far between today due to regulation, and the hit miss success rate of taking them apart, cleaning and chemical restructuring the plates to take a charge again. Sealed plastic batteries have made that even harder. So it will do no good to drain the acid, and it will be a nasty safety issue as well. I have repaired a cracked case (physical damage) with the acid removed from that cell, but it cost a pair of jeans and 3 hours. Jim
