5 Considerations For Maximising The Life Of Your UPS Batteries

by Analytics OMG January 19, 2022

Whatever type of UPS batteries you install, they will eventually need to be replaced. How long it will be before you have to replace them will depend on a number of factors, some of which you may be able to control and some of which you may not. Under ideal operating conditions, UPS batteries can last as long as 5 years and still retain 50% of their original capacity. But under less ideal conditions, the useful life of a UPS battery can be significantly shortened. If you are interested in maximising battery life on UPS systems that your business relies on during power outages, the 5 considerations we have listed below should help you to achieve your aim.

5 factors to consider when trying to maximise UPS battery life

If you can ensure that your UPS systems are operating in the best conditions possible, you will be able to extend the life of your batteries.

Maintain a steady temperature – The rated capacity of any UPS batteries you buy will be based on them being used in an area where the ambient temperature is 25°C. If the area in which they are installed is hotter than this, their capacity will be reduced. As a rule, for every 8-10°C increase in temperature (over and above 25°C), capacity will be reduced by 50%. With this in mind, air-conditioning is a must on hot summer days.
Minimise the number of discharge cycles – If you experience a power outage, there is not much you can do about the fact your batteries will be discharged before being recharged again once the power is back on. However, you should avoid running equipment on your UPS system when it’s not necessary to do so. UPS batteries will naturally lose capacity as they go through more discharge cycles.
Maintain your batteries – Periodical maintenance, performed by a trained professional, can help to extend the life of your batteries. It will also help to ensure that any failing units are identified and replaced before they have a chance to cause a serious problem. If your system is not being used in ideal operating conditions, UPS battery maintenance is especially important.
Don’t store replacement batteries for too long – It is a good idea to keep spare batteries on-site but don’t overstock. Any batteries that are stored for more than 18 months before being used could have a shorter than expected lifespan.
Choose the right batteries – All of the above tips for maximising battery life on UPS systems will be of little use if you choose batteries that are unsuitable for your needs. Make sure they have the capacity and power to run the equipment you would like your UPS system to support.
