Your UPS system is one of the most crucial components in your critical power infrastructure, and for your UPS, the batteries are really the “heart” of that system. Even though your UPS needs that heart, batteries are often neglected. We’ll go into more detail about each type of battery that can be used in a UPS system and the advantages and disadvantages for each type. It should be noted though, that regardless of the batteries you choose, all batteries decrease in their ability to store and deliver power over time. However, if you follow all guidelines for storage, maintenance and usage, eventually you will still have to replace UPS batteries on a schedule to get the best usage out of your UPS.
Knowing what your UPS system does should be just the beginning of your UPS knowledge. Going a step further to learn the key components of a UPS will help you understand how it works, identify potential problems and help you avoid them. Read more
Now that we have a better idea of our UPS battery options from our previous article, we can take a look at these options individually in more depth. We will start with the most popular option currently, the VRLA UPS battery.
VRLA, or Valve Regulated Lead Acid UPS batteries, are also sometimes called “maintenance free” batteries. This term is a misnomer, as VRLA batteries still require cleaning and regular functional testing. The term “maintenance free” comes from the fact that you are not able to add fluid to the battery. The term “valve regulated “means these batteries limit the inflow and outflow of gas to the cell.
In a standard UPS configuration, VRLA batteries are typically set up in internal or external strings that can range from 1 to 40 batteries, depending on the application they are being used for. You may also see either single or multiple strings running in parallel to each other.
VRLA batteries are the most popular UPS battery type currently. Why the popularity? There are four easy reasons: Read more
