The loss of electrolyte in a flooded lead acid battery occurs through gassing as hydrogen escapes during charging and discharging. Venting causes the electrolyte to become more concentrated, and the balance must be restored by adding clean water.
Venting causes the electrolyte to become more concentrated, and the balance must be restored by adding clean water. Do not add electrolyte as this upsets the specific gravity and shortens battery life by promoting corrosion. Loss of electrolyte in sealed lead acid batteries is a recurring problem that is often caused by overcharging.
Do not add electrolyte as this upsets the specific gravity and shortens battery life by promoting corrosion. Loss of electrolyte in sealed lead acid batteries is a recurring problem that is often caused by overcharging. Careful adjustment of charging and float voltages, as well as operating at moderate temperatures, reduces this failure.
The following are some common causes and results of deterioration of a lead acid battery: Overcharging If a battery is charged in excess of what is required, the following harmful effects will occur: A gas is formed which will tend to scrub the active material from the plates.
According to Battery University, keeping a battery operating at a low charge (below 80%) can lead to stratification, where the electrolyte “concentrates on the bottom, causing the upper half of the cell to be acid-poor.” This can affect the overall performance of the battery and eventually lead to failure.
All lead-acid batteries will naturally self-discharge, which can result in a loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery’s electrolyte and the chemistry of the plates.

For ordinary lead-acid batteries, the electrolyte level decreases, exposing the upper part of the plate to the air; for valve-regulated sealed lead-acid batteries, it is the loss of water that reduces the saturation of the electrolyte in the diaphragm, making the plate ineffective.

VRLA batteries, sometimes called "starved electrolyte" or "immobilized electrolyte (or erroneously termed "sealed lead-acid" [SLA] or "maintenance free"), have far less electrolyte than a vented battery, and the cell container is opaque so it is impossible to see what is happening internally.
Over-watering a lead-acid battery, which is usually caused by watering the battery in a discharged state, causes the electrolyte to overflow out of the vent caps. This results in a loss of sulfuric acid from the electrolyte in the battery, which can never be replaced, as only water should be added to batteries. The loss of electrolyte will ...

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. The specific gravity of sulfuric acid is measured with a hydrometer. Lead-acid …
