How can I maximise the life of my VRLA battery system-1

Valve Regulated Lead Acid (VRLA) batteries play a crucial role in providing power in UPS, communications and road sign applications. For large scale installations requiring multiple VRLA batteries, a common concern is how to maximise battery service life to reduce maintenance time and replacement costs. 

There are many simple things you can do to extend the life of a more extensive VRLA battery system, such as a 48V1000Ah energy storage system, including:

It is also good practice to use a battery equaliser to further extend the life of your VRLA batteries.

But what is a battery equaliser? How does it help your system?

How can your system suffer?

Temperature, battery cell chemical composition and individual battery self-discharge rates can cause battery systems in series to become unbalanced. This imbalance will result in the batteries incorrect charging (under or overcharging) ultimately causing sulphation and premature plate corrosion. 

As the battery system ages, this voltage discrepancy will increase, resulting in early battery system failure. 

If you check each cell without an equaliser, you may get a variation of up to 1.0V between the lowest and highest reading. 

Enter the battery equaliser...


Why should I use a battery equaliser?

The Valen battery equaliser equalises or balances out these voltage discrepancies as soon as a 2mV battery voltage difference has been detected. 

True to its name, a battery equaliser is designed to even out the voltage.

It works by taking the excess energy from the higher voltage cell and dispensing it into the lower voltage cell. 

As a result, BOTH cells are cared for, and battery life is extended.

By adding a Valen battery equaliser to your battery system, performance will be enhanced, and the battery life drastically improved. 

Valen equalisers come in a variety of sizes, allowing them to be retrofitted into a variety of applications. Multiple Valen battery equalisers may be used on one system for the complete system to be covered.
