Regularly checking and monitoring the condition of your UPS batteries is essential to ensure their reliability. There are various signs that UPS batteries need to be replaced, including the fact they’re nearing the end of their lifespan.

Is it time to replace your old UPS batteries?

UPS batteries have a limited lifespan and usually last between 3 to 5 years. It can be best to replace the batteries before this time, even if they haven’t shown signs of failure, just to be on the safe side.

Another sign is that you have reduced back–up time. This is obviously something nobody wants when running a busy data centre. If you notice a significant decrease in the amount of time the UPS can provide backup power, it may indicate that the batteries are no longer holding a charge effectively.

Do you find yourself frequently having to replace your UPS batteries?

This can suggest an issue with the charging system or the quality of the batteries themselves. At UPS Battery Shop we only ever offer high quality batteries that offer exceptional longevity and reliability. That includes those for leading brand APC by Schneider Electric.


Update your UPS system so it comes with battery testing features. 

Fortunately, many modern UPS systems come with built-in battery testing features. It’s important to regularly perform battery tests using the UPS management software to evaluate the health of the batteries. If the test results indicate a decline in capacity, it’s a sign that replacement may be necessary.

Pay attention to audible alarms or warning lights.

If you hear an alarm or see a warning light, consult the UPS manual to interpret the specific alert. You might also want to check your batteries for any visible damage, like leakage, bulging, or corrosion. This may indicate a problem with the battery.

Overheating is another sign UPS batteries need replacements. 

Excessive heat can damage batteries. If you notice that the batteries or the UPS unit itself is unusually hot, it could be a red flag. It’s vital to check your system is getting proper ventilation and cooling.

Another sign is an inconsistent power supply. If your electronic equipment experiences intermittent power interruptions or fluctuations even when connected to the UPS, it might indicate a problem with the battery. Weird odours should also be investigated, particularly if it’s a sulphur smell because this can be a sign of a battery leak or other issues.

Communication Issues:

If the UPS is not communicating properly with connected devices or the management software, it might be a sign of internal battery problems.
