Loss of Electrolyte in Batteries: Causes, Effects, and Mitigation

In sealed lead-acid batteries, or VRLA batteries, electrolyte loss often stems from overcharging. When charging voltages exceed specified limits, excessive gassing occurs, leading to the escape of electrolyte. To mitigate this, it is crucial to control charging voltages carefully and operate these batteries within moderate temperature ranges to

BU-201: How does the Lead Acid Battery Work?

The sealed battery contains less electrolyte than the flooded type, hence the term "acid-starved." Perhaps the most significant advantage of sealed lead acid is the ability to combine oxygen and hydrogen to create water and prevent dry out during cycling. The recombination occurs at a moderate pressure of 0.14 bar (2psi). The valve serves as a safety vent if the gas buildup

Lead Acid Batteries

As the above equations show, discharging a battery causes the formation of lead sulfate crystals at both the negative and positive terminals, as well as the release of electrons due to the change in valence charge of the lead. The formation of this lead sulfate uses sulfate from the sulfuric acid electrolyte surrounding the battery.

How Lead-Acid Batteries Work

During the discharge process, the lead and lead oxide plates in the battery react with the sulfuric acid electrolyte to produce lead sulfate and water. The chemical reaction can be represented as follows: Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O As the battery discharges, the concentration of sulfuric acid decreases, and the concentration of lead sulfate increases. This

BatteryStuff Articles | The Lead Acid Battery Explained

Basically, when a battery is being discharged, the sulfuric acid in the electrolyte is being depleted so that the electrolyte more closely resembles water. At the same time, sulfate from the acid is coating the plates and reducing the surface area over which the chemical reaction can take place. Charging reverses the process, driving the sulfate back into the acid. That''s it
