If a lead acid battery runs out of water, meaning the electrolyte has fully dried up or the battery has been tilted or stored upside down causing the electrolyte to spill, this is the main concern.
When the electrolyte levels in a flooded lead-acid battery go down exposing the plates, always use distilled water instead of acid when topping off a flooded lead-acid battery. During the charging and discharging processes, water that undergoes electrolysis and evaporation is lost from the battery. This leaves a concentrated sulfuric acid solution.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
A lead acid battery, including flooded electrolyte types, should not have its acid completely removed once it has been filled and charged. It is important not to remove the acid. A lead acid battery consists of several major components, including the positive electrode, negative electrode, sulphuric acid, separators, and tubular bags.
When a lead acid battery is drained of its acid, the wet moist negative electrodes come in contact with atmospheric oxygen, triggering an exothermic reaction that releases heat and discharges the negative plates (electrodes), oxidizing the sponge lead to lead oxide.
Flooded electrolyte lead acid batteries do not cause thermal runaway because the electrolyte, which acts as a coolant in these batteries, helps prevent such an occurrence. Designers of flooded electrolyte lead acid batteries do not face the thermal runaway problems that are common in sealed maintenance free (SMF) or valve regulated lead acid (VRLA) batteries.
