​5 Ways to Maximize Battery Efficiency in a UPS

Batteries are a crucial part to a UPS. Even with a well-maintained UPS, if the battery is not given the same detailed care, it can cause catastrophic damage to your UPS, business and a serious loss of investment. Whether the battery is a sealed lead acid battery also known as VRLA or of a lithium Ion composition, maintenance of your UPS battery back up can maximize its lifetime and efficiency so that you get the most out of your investment which is Best Uninterruptible Power Supply

Here are 5 ways to maximize the longevity and efficiency of your UPS battery back up:


Poor Storage is one of the most common reasons for battery failure. Unused batteries are often forgotten and installed without much thought. However, even idle batteries discharge small amounts of energy. All batteries need to be regularly charged at least once a quarter. If batteries are not regularly charged, their life expectancy is reduced greatly and will ultimately lead to complete battery failure.


We learned in a previous blog that UPS requires precision cooling. For optimal functionality of your UPS battery back up, temperatures must be maintained at 68-77°F. The same is necessary for batteries. Idle batteries require to be stored at temperatures of 50°F or less. The rated capacity of batteries currently in use are ambient temperatures similar to the UPS— 68-77°F. A rule of thumb to always remember is for every 4°F over the recommended temperature, battery life decreases by as much as 50%.


When a power failure of the main electrical grid occurs, UPS battery back up is called into action. However, after power is back and up and running, and the job of a UPS is complete for the time being, but batteries still need to be recharged for future use. Over-cycling of UPS batteries can also stunt its life. Constant back-to-back cycling of batteries without proper charge will eventually lead to battery deterioration. The duration of each cycle and number of cycles will affect the life of a battery and will ultimately need replacing.

4.Correct Float Voltage

Correct float voltage of a UPS battery is a critical component that must be maintained for peak performance. Undercharging or a low float voltage of a battery can result in the formation of sulphate crystals. These crystals harden and overtime, reduce the overall capacity of the battery.


Likewise, overcharging or a high float voltage can also cause similar outcomes. A high float voltage causes internal dry-out meaning thermal runway from a build-up of hydrogen and oxygen gases. This not only causes battery collapse but is also extremely hazardous as it can cause fires.

Overall, the key to ensuring a fully functioning and safe UPS battery back up is to schedule regular maintenance checks and servicing. This will not only prevent any irregularities when the UPS is needed but also safeguard your wallet from any unnecessary expenses. Read our blog on the importance of UPS maintenance to gain a better understanding of how maintenance checks work.
