9 Indices That It’s Time to Replace Your UPS Battery

The Impact of Temperature on Lead-Acid Battery Performance

For your business, network uptime is crucial. The UPS (Uninterruptible Power Supply) is a crucial part of maintaining the uptime of your technology. As they typically reside at the bottom of the gadget rack and have long lifespans, these devices are frequently ignored. These tools, though, have the potential to be your disaster protection systems’ and redundancy plans’ Achilles Heel if they are neglected. Ten indicators that it’s time to swap out your UPS battery are listed below:

The Impact of Temperature on Lead-Acid Battery Performance

1. Three to five years have passed since the purchase date

A UPS’s life cycle can last up to ten years, but many batteries only last three to five. Depending on how vital the systems the UPS is supporting are, it is advised to think about a battery change every three to five years. The last thing you want in a serious power outage situation is for the battery to fail because it was past its life expectancy, which is a mistake you could have avoided. If the time comes for your UPS to be replaced and you want to know your choices, get in touch with us.

2. The battery life is not as long as claimed.

The lifespan of a battery can be shortened by a variety of factors, such as material flaws, temperature fluctuations, humidity, and other environmental causes. If the battery is not working according to expectations during your testing cycles, it could be time to replace the battery.

3. You detect the bulging of the chassis or other chassis damage.

Older lead-acid batteries tend to expand with time, which might cause the chassis to be distorted. Replace the batteries in that device right away if you see any leakage, or heat- or acid-related discoloration.

4. When there is a power loss, systems are unavailable

This is presuming that the equipment that went offline was correctly connected to the UPS or the PDU that is connected to the UPS. If you use a regular preventative maintenance program to check the health of your UPS, this should never occur.

5. Visits for preventative maintenance have been missed

You can confirm that those units are operating as planned, make sure to test them out. Regular upkeep can avert a variety of potential problems and guarantee that your UPS will be there to safeguard your equipment when you need it most. We offer this assistance. Make a maintenance appointment with us right now.

6. Batteries behave erratically or display incorrect voltage readings

If the UPS displays inconsistent voltage readings or acts unexpectedly during your maintenance cycles or disaster preparedness testing, be careful to rule out the battery as the possible cause. When a technician tests a battery, impedance or resistance values will be obtained in addition to voltage readings. Make careful to include impedance and resistance testing in your testing cycles as the majority of UPS systems won’t self-test these parameters. When it matters most, Alber Battery Monitoring can help ensure that your UPS battery is operating at its best.

7. The UPS is situated in a warm area.

Battery life can be severely shortened by heat. Battery life and the lifespan of your entire technology equipment can be significantly shortened by prolonged exposure to temperatures exceeding 80 degrees Fahrenheit. We advise installing thermal management and cooling equipment as soon as feasible if the temperature at the site where your UPS equipment is located is routinely above 80 degrees. Don’t rely on a UPS running in a heated building having a battery life of 3 to 5 years.

8. Inadequate battery runtime or load capacity

Due to the development of technology, it is also feasible to exceed the UPS load capacity, which is similar to overflowing the device’s specified power ports. Make careful to compare your power usage to your uptime needs and modify your UPS or battery choices to suit your requirements.

9. Environmental sustainability and energy efficiency

The introduction of the new lithium-based batteries is the subject of a bonus tip. If you still use lead-acid batteries, switch to lithium-ion ones to benefit the environment, reduce your carbon footprint, increase uptime, get longer battery life, and get a better return on your investment.


When it’s time to replace your equipment, make sure you recycle or properly dispose of the old batteries. For your infrastructure to remain operational, routine maintenance and testing are essential. Don’t just rely on your equipment blindly; constantly check it to make sure you’ll be prepared for emergencies.
