Uninterruptible Power Supply (UPS) systems are the unsung heroes of business continuity. They safeguard critical operations, data, and equipment from power disruptions. Yet despite their importance, many businesses still fall victim to common UPS maintenance myths, leading to unexpected downtime, costly repairs, and reduced equipment lifespan.
In this blog, we’ll debunk the most common misconceptions about UPS maintenance, UPS systems, and UPS batteries, and share what you can do to protect your investment.
Myth 1: UPS batteries last as long as the UPS itself.
Reality: The UPS system and its batteries have very different lifespans.
While a well-maintained UPS unit can last 10–15 years, UPS batteries typically need replacement every 3–5 years, depending on usage, temperature, and maintenance. Batteries naturally degrade over time, even if the UPS isn’t heavily used.
Neglecting battery health can lead to reduced backup time, system failure during power loss, and even damage to the UPS unit. Regular battery checks and timely replacements are essential to keeping your UPS reliable.
Myth 2: You only need to replace batteries when they fail.
Reality: Waiting for a battery to fail before replacing it is a costly mistake.
As UPS batteries degrade, they lose capacity, which means your system might appear operational but won’t provide sufficient backup during an outage. A proactive replacement strategy ensures that your business stays protected at all times.
Routine UPS maintenance includes battery impedance testing, visual inspections, and scheduled replacements before failure occurs.
Myth 3: Maintenance isn’t necessary if the UPS is rarely used.
Reality: Even idle UPS systems require regular maintenance.
UPS batteries naturally self-discharge, and environmental factors like heat and humidity can accelerate wear. Dust accumulation, loose connections, and outdated firmware can also affect system performance.
Regular maintenance – including firmware updates, environmental checks, and load testing – keeps your UPS system ready for when you need it most.
Myth 4: All UPS maintenance is the same.
Reality: Not all maintenance programs are created equal.
A one-size-fits-all approach can overlook critical system details. Tailored maintenance plans, based on the UPS model, load requirements, and operating environment, ensure maximum reliability.
Working with a trusted service provider (not your regular friendly electrician) helps identify early warning signs and extend the lifespan of both the UPS system and its batteries.
Myth 5: Monitoring software makes physical inspections unnecessary.
Reality: Remote monitoring is an excellent tool, but it can’t replace hands-on inspections.
While software alerts you to certain issues like load imbalances or temperature changes, it can’t detect physical degradation, corrosion, or loose connections. A complete UPS maintenance strategy includes both digital monitoring and on-site inspections.
