View more6 FAQs about [Lead-acid battery charging and water loss]
What happens if a lead acid battery is flooded?
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.
What happens if you vent a lead acid battery?
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.
Why do batteries lose water?
However, in many applications, batteries are experiencing relatively long periods of open-circuit stand. Water loss by “self-discharge electrolysis”, that is oxygen evolution at the positive plates, and hydrogen evolution at the negative plates, may then represent an important part of total water loss .
What causes a battery to lose electrolyte?
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.
Can you add electrolyte to a lead acid battery?
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.
What happens if a battery is flooded?
Lead-Acid Batteries In flooded lead-acid batteries, electrolyte loss primarily occurs through gassing during the charging and discharging processes. When the battery charges, hydrogen and oxygen gases form, which can escape into the atmosphere. This loss of gas results in a concentration of the remaining electrolyte, diminishing its effectiveness.
