What is a valve regulated lead acid battery?

L121250AFR, TPL121600FR. 0S MU-1000RERE1200 1. Battery ConstructionUnlike the traditional flooded type of lead acid batteries, valve-regulated lead acid (VRLA) batteries use an electrolysis of water from the electrol te caused by overcharge. This generates oxygen (O2) gas on the positive plates and can be absorbed by the hydrogen (H2) ga

What is a valve regulated lead-acid battery (VRLA)?

This dominance is particularly evident in the field of Uninterruptible Power Supplies (UPS). A Valve Regulated Lead-Acid Battery (VRLA battery) is a type of lead-acid battery characterized by its sealed, maintenance-free design. It does not require the addition of acid or water during its service life.

How should a lead-acid battery be stored?

Lead-acid batteries should be stored in a well ventilated area away from sparks or open flames. Keep damaged batteries in properly labeled, acid-resistant secondary containment structures. Ensure that vent caps are securely in place.

Do flooded lead acid batteries need distilled water?

In ordinary flooded lead acid batteries, these gases are allowed to escape hence the need to have distilled water added from time to time to replace the lost water. In contrast, VRLA batteries retain the generated gases within the battery as long as the pressure remains within safe levels.

What is a valve regulated lead-acid cell?

In practice, the recombination efficiency is not 100% and a pressure relief valve regulates the internal pressure at a relatively low value, generally below 10 psig. For this reason, sealed lead-acid cells are often called “valve-regulated lead-acid” (VRLA) cells.

Are valve regulated batteries dangerous?

Although all valve-regulated batteries have the electrolyte immobilized within the cell, the electrical hazard associated with batteries still exists. Work performed on these batteries should be done with the tools and the protective equipment listed below.
