What Are Valve-Regulated Batteries And How To Manage Them?


Valve regulated batteries have been around for a while, and they are here to stay. These robust batteries have a life span of over 3-12 years and have completely revolutionized the electric industry. So, what makes a valve regulated battery so unique, and what are its prospects? Keep on reading further to find out.


What Is A Valve Regulated Battery?

A valve regulated lead acid (VRLA) battery is characterized by a limited amount of electrolyte absorbed in a plate separator or formed into a gel. This leads to proportioning of the negative and positive plates to facilitate oxygen recombination within the cell and the presence of a relief valve that retains the battery contents regardless of the position of the cells.

Even though these batteries are commonly referred to as sealed lead-acid batteries, they always incorporate a safety pressure relief valve. In contrast to vented batteries, a VRLA battery will not spill its electrolyte if it is inverted.

VRLA batteries are divided into two categories:

§  Absorbent glass mat (AGM): The acid is absorbed and immobilized by very thin fiberglass mats between the plates in this sort of battery. This design allows the acid to reach the plates quickly and provides a rapid reaction between the acid and the plate material.


§  Gel cell or gel battery: The Gel Cell Battery features an immobile jelly-like electrolyte in which sulfuric acid is combined with fumed (pyrogenic) silica as a thickening agent. The Gel Cell can be installed in any position and is resistant to severe temperatures, stress, and vibrations because of its immobile gel-like electrolyte structure.

The gel cell and AGM varieties of VRLA can be placed in any orientation and do not need to be maintained regularly due to their structure.


Where Are Valve-Regulated Batteries Used?

The valve regulated battery has been the most extensively utilized energy storage device for medium and large-scale applications for many decades. They are commonly used in large portable electrical devices, off-grid power systems, and other applications that require a large volume of storage at a lower cost.

In recent years, an alternate design has begun to replace the old, flooded architecture of the battery. The valve-regulated battery does not require the electrolyte solution to be refilled with water, does not leak liquids, and may be used in any orientation.


What is the Life Expectancy of Valve Regulated Batteries?

Valve-regulated batteries have a lifespan of 3 to 12 years, although, like with all batteries, their maximum life is determined by how well they are cared for. Overcharging is one of the major reasons these batteries act up in the first place.

The usage of a low voltage alarm provides visual and auditory alerts when a VRLA battery is about to be significantly over-discharged, ensuring that you get the most cycle out of it and minimize over-discharge occurrences.


Installation of the Valve-Regulated Batteries

When installing these sturdy batteries, there are a few things you must keep a check on:

§  Connect and torque connections according to the manufacturer's specifications.

§  Examine the battery for good positive-to-negative connections.

§  Check the voltage of the battery and inspect the connections thoroughly.

§  Label each cell/module with its name.

§  Interconnection resistance should be read and recorded.

§  Acceptance testing of a battery should be done at the point of manufacture. An acceptance test verifies that the battery performs as expected in terms of discharge rate and duration.


How to Manage Valve-Regulated Batteries?

To get the maximum output from valve-regulated batteries, you must practice maintenance rituals religiously. Below listed are some of the crucial things you must take care of:


§  Charging in the Right Manner

Valve-regulated batteries are prone to undercharging and overcharging. Thus you must know the battery's capacity and ensure that it is always charged to maximum capacity. You should also avoid discharging the battery below critical limits. If you care about your valve-regulated battery, learn about its capacity and get a voltmeter or another measuring tool to check the voltage at regular intervals while charging and when it's in use.

You might not know if you are sometimes charging your battery incorrectly, but as long as you are following the guide, you are good to go!


§  Store the Battery in A Safe Place

Self-discharging is a problem with valve-regulated batteries, and if you don't store them properly, their life cycle may be shortened. These batteries usually are very hot right after use, and if you don't keep them in a well-ventilated area, the self-discharge process will be quick.

Batteries should be stored in a cool, dry, well-ventilated area away from the harsh weather and should not be kept near open flames since they can quickly catch fire and explode, resulting in injuries. If you are storing the battery for an extended period, it's preferred to take monthly voltage readings and adjust the charge accordingly. If you store the battery for too long, it will discharge, and if you use it when it is discharged, you risk damaging the battery plates.


§  Using the Right Charger

Most deep-cycle applications have some form of charging infrastructure already installed for battery charging. However, there are still systems with deep-cycle batteries that require a specific charger.

Today's chargers come in a variety of shapes and sizes. They are normally rated by their start rate, which is the amount of current the charger will give at the start of the charge cycle in amperes. To avoid overcharging and damaging the battery plates, a suitable valve-regulated battery charger should be temperature and voltage regulated.

§  Make Sure the Terminals Are Clean

Ensure that the battery terminals are clean after charging or usage to remove any residue on the terminals' surface. The effectiveness of batteries is reduced by residue on the surface of battery terminals, and their capacity is not fully utilized.


The Bottom Line

That's all there is to valve regulated batteries in a nutshell. These versatile power sources significantly impact a wide range of applications, from industrial to recreational. They are one of the most reliable and cost-effective ways of energy storage available on the market today if adequately cared for.
