Battery failure is the leading culprit behind the majority of UPS catastrophes. But despite batteries’ vulnerability to premature failure, you don’t have to be a victim. We’re going to run through the top five causes of premature battery failure and how you can prevent it. Read more

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.
Managers responsible for critical IT loads or other high demand applications want to make sure that their equipment is protected by the most reliable, efficient technology possible. This is especially true when it comes to UPS battery back-up technology. There has been great interest recently in Lithium-Ion battery technology and the UPS Lithium-Ion Battery market is rapidly expanding. Toshiba launched their own battery technology called SCiB (Super Charge Ion Battery) back in 2008. While this technology has been available for many years, it’s introduction into the UPS system has been fairly recent. The newest iteration of this battery is showcased in the Toshiba G9000 series UPS unit. We will discuss the make-up of the SCiB and also some of it’s main advantages compared to similar battery technologies. Read more
In our last article, we discussed DC power plants, what they are, and how they are often used. Just like any back-up power system, DC power plants need regular service checks and maintenance performed to work optimally. It is important to state that DC plants, although similar to the function of UPS systems, have many functional differences and require unique training when performing annual maintenance. During a preventative maintenance visit a technician will usually isolate individual rectifiers and charging components to evaluate function and longevity. This practice helps to reduce the risk of a potential failure before it happens. Read more
As much as 65% of all UPS back-up system power failures are battery related. That’s a staggering number, but is easier to understand when you consider all the potential issues that can affect UPS batteries. Power anomalies, overheating, improper charging or low electrolyte levels for certain types of batteries can all cause serious issues for the UPS.
The second battery on our “get to know you” list is the Wet Cell, or Flooded Cell battery. UPS Systems are used in a variety of applications and, as a result, may require a wide variety of run time requirements or discharge characteristics. The battery cell is comprised of a hard plastic enclosure, typically Polycarbonate or Styrene Acrylonitrile (SAN) Plastic, lead plates and an electrolyte that allows the flow of current. 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
