Most businesses don’t think about their UPS system until something goes wrong. But when that system fails, it’s already too late. Whether you’re running a comms room, server rack, or mission-critical data setup, keeping your UPS in good shape is essential. UPS maintenance isn’t just a technical checkbox, it’s how you avoid costly downtime.
Why UPS Maintenance Matters
A UPS is your last line of defence against a sudden power loss. But batteries degrade, connections loosen, and firmware becomes outdated. Even high-end UPS systems can fail if they’re neglected.
We’ve seen it happen, expired batteries that quietly stopped holding charge, dusty fans causing overheating, or software glitches that trigger unexpected shutdowns.
Warning Signs You Shouldn’t Ignore
- Frequent alarms visual or audible
- Reduced depicted runtime (if load has not changed)
- Excessive temperature in its environment – risk to its internal batteries
- Batteries that are over 3 years old
- Visible dust, corrosion, or heat damage
What Checks Should You Be Doing?
Monthly
- Visual inspection
- Listening for abnormal sounds or depicted alarms
- Checking for error codes
- Its loads are balanced
- Its environmental temperature remains correct
Annually (or twice a year if critical)
- Full load test
- Battery voltage and impedance testing
- Fan and filter cleaning
- Firmware updates
- Testing bypass and alarm functions
For SMEs, it doesn’t have to be complicated. Most businesses just need a realistic UPS servicing schedule and a responsive provider on call if something goes wrong.
