How to Recondition Lead Acid Batteries
The Chemistry Behind Lead Acid Batteries. When a lead acid battery is charged, the sulfuric acid in the electrolyte reacts with the lead in the positive plates to form lead sulfate and hydrogen ions. At the same time, the lead in the negative plates reacts with the hydrogen ions in the electrolyte to form lead sulfate and electrons.
Influence of H2SO4 concentration on the performance of lead-acid ...
The influence of sulfuric acid concentration on negative plate performance has been studied on 12 V/32 Ah lead-acid batteries with three negative and four positive plates per cell, i.e. the negative active material limits battery capacity.

Investigation of the electrochemical behaviour of lead dioxide in aqueous sulfuric acid …
The charge-discharge characteristics and the aging mechanism of PbO2 layers in contact with sulfuric acid solutions of different concentrations (1.5–5.0 M) were studied by using combined cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM) techniques. For this purpose, thick lead dioxide layers were …
Concentrating Sulfuric Acid
Sulfuric acid is an incredibly useful chemical and is readily available in the form of ''Battery Acid'' used in Lead-Acid batteries (such as those found in automobiles).
