How to Extend the Battery Life of your UPS?

UPS is one of the most significant investment you make for work or play. We say that because Uninterruptible Power Supplies keep up critical devices working when grid power fails. Backup from the UPS allows you to save that complex Excel sheet which took hours to compile, or finish watching a movie and avoid an unwanted cliffhanger or finish a video game level and save your progress. Moreover, modern UPS devices come with surge protection to protect your devices from momentary voltage spikes.

But a UPS is as good as its battery. If your battery is not in a good shape, the power backup starts to drop rather quickly. Battery health also plays a role in protecting your appliances from the aforementioned power surges. So, today we are sharing some tips and tricks that will help you get the most out of your UPS batteries. 

Keep the UPS Cool and Dry

A general rule for maintaining the health of computing and power devices also applies to the UPS. Keep the UPS in a location with temperatures below 25° C or 77° F. Every 8 degree increase in temperature reduces the battery life by half. Also, make sure there’s at least 2 inches of space on each side of the unit for venting the heat. Finally, never place the UPS near an open window or in places with high moisture.

Store replacement batteries with care

It’s always better to have some replacement batteries handy if your UPS units are frequently in use or operate full-time. Just like the unit, store the batteries in a cool and dry place but not longer than 12 months. When batteries are kept unused for too long, they start losing capacity and will have a shorter lifespan when used. If the storage exceeds 18 months, permanent loss of capacity can also happen. Ideally, UPS batteries should be stored in a location with temperature below 10°C or 50°F.

Periodically calibrate the UPS batteries

Executing runtime calibration can extend the battery backup of your UPS. Make sure that you are executing the calibration once or twice a year to keep the batteries in good health. However, do not overdo the exercise since excessive calibration can be a costly mistake as it significantly reduces battery capacity.

Perform regular maintenance

Watch out for abnormal behavior in the UPS performance instead of ignoring the frequent beeps. If your batteries are fully discharged in some instance, they must be recharged within 48 hours. Measure battery backup through capacity testing. Dropping below 80% from the original capacity is the sign of a “cooked” battery. Replace batteries timely to avoid stressing other internal components, as overheating batteries may cause melting of plastic and metal components inside the unit.

Use energy saving devices

Finally, help your UPS battery extend its life by using more power efficient devices. Devices with low power consumption keep UPS temperature under control, thus extending your battery’s lifespan. Also, use good quality wires to avoid high resistance and increased load on your UPS backup.

With those tips in mind, get ready for more productive work hours and extended play. Just in case you are looking for a new UPS, head over to to get a brand new APC UPS delivered to your doorstep.
