An Overview of UPS Battery Types

Batteries: The Heart of Your UPS System

If you think of your UPS as the “nervous system” of your back-up power management set-up, the batteries of your UPS are the “heart” of that system. And there are several types of batteries that can make up the heart of that system.

But all batteries (no matter which ones you choose) will decrease in ability to store and deliver power over time. Even if you follow all guidelines for their storage, maintenance and usage, UPS batteries will need to be replaced on a schedule to optimize their performance.

There are three main types of UPS batteries — Valve Regulated Lead Acid (VRLA) batteries, Flooded Cell (VLA) batteries and Lithium Ion batteries. Each type of battery has preferred uses in specific types of environments.

Valve Regulated Lead Acid (VRLA)

The term “valve regulated” relates to the way gas is released from the battery. If the gas pressure becomes too great in the battery, a valve will vent when the gas reaches a certain pressure.

Quick Facts

Battery Management

With battery management, you receive updates on your battery’s current charge, voltage and cell voltage balance. It also adjusts for issues related to temperature by disconnecting single batteries or strings if temperatures rise above safe levels. The battery management can also send alarms on the UPS and notify the battery cabinet monitor. 

 

It is important to understand your UPS battery options, and how to manage them, just as well as your options for the machine itself. Contact QPS today to speak with our experts about how best to manage your UPS battery life and UPS battery replacement.
