Battery Failure Prevention
Carry out regular checkup and preventive maintenance every six months. The inspection team will identify, assess and fix vulnerabilities to prevent battery failures.
Capacitors – UPS capacitors help to smooth, filter and store energy. It’s also one of the UPS components that’s prone to failure. They age and degrade over time. Factors such as excessive heat or current can speed this up.
A serious capacitor failure will trigger the UPS to bypass mode. This’ll leave the critical load unprotected.
Failure Prevention
An effective way to prevent capacitor failure is to replace them ahead of their rated service life.Carry out replacements every five-seven years.
Fans – UPS fans help keep the components cool and safe. Of course, the number of fans depends on the size of the UPS system. Fan failures can cause overheating and damages to the installation.
The fans could fail due to the following:
- Wear and tear as a result of constant rotations.
- When the grease in the sealed bearings dissipates.
- Dusts could cloak the vents, thereby causing the fan to work harder.
Failure Prevention
You can prevent fan failure by replacing them ahead of their rated service life. It’s advisable to change the fan and capacitor at the same time. This practice is known as UPS Overhaul

Filters – dusts can block the air filters and this could cause harmonics and electrical noise. It could also cause the UPS to shut down due to overheating.
Failure Prevention
Inspect and replace the filters every month to prevent downtime due to air vent cloaking. UPS air filters are inexpensive.
