Ensure the lead-acid battery has enough water to cover exposed plates before charging. After charging, fill water until it reaches the bottom of the vent, you should add distilled water to your lead-acid battery until the electrolyte covers the plates by half an inch. The amount varies based on usage, temperature, and charging practices
Lead-Acid battery electrolyte. The electrolyte of lead-acid batteries is a dilute sulfuric acid solution, prepared by adding concentrated sulfuric acid to water. When charging, the acid becomes more dense due to the formation of lead oxide (PbO2) on the positive plate. Then it becomes almost water when fully discharged.
