UPS maintenance is often dismissed with a simple "checked, working" statement.
But in real life, most breakdowns are the result of incorrect or inadequate maintenance .
Let's be clear:
Improperly performed UPS maintenance is more dangerous than no maintenance at all.
Below you will find a clear explanation of the most common UPS maintenance errors in the field and why they are risky.
1️⃣ Saying "The batteries are good" just by measuring the voltage ❌
This is the most common mistake.
-
The battery may show normal voltage when idle.
-
But it collapses instantly under load.
📌 Actual situation:
A battery cannot be considered healthy without performing a load (discharge) test.
Because of this mistake:
-
I have a UPS, but it won't work during a power outage.
-
The problem arises during the first power outage.
2️⃣ Not Performing Load Tests 🔌
If load testing is not performed during UPS maintenance, the maintenance is incomplete.
The mistake that was made:
-
Press the test button and say "OK".
-
Performing a test without a load.
📉 Result:
-
Actual working hours are unknown.
-
UPS capacity shortage goes unnoticed.
3️⃣ Replacing Just One Battery 🔋
In UPS systems with multiple batteries:
❌ The "let's replace what's broken" approach
What will this lead to?
-
A new battery puts a strain on the old ones.
-
The battery pack becomes unbalanced.
-
The new battery will also die quickly.
📌 The correct rule:
All batteries inside the UPS should be replaced together.
4️⃣ Not Performing Thermal Camera Checks 🌡️
Electrical measurements may be normal.
But heating problems remain invisible .
This error:
-
Loose connections go unnoticed
-
Overheating went unnoticed.
-
Fire risk
Why does that happen?
📌 Hidden risks remain in UPS maintenance that doesn't involve thermal testing.
5️⃣ Not checking the age and manufacturing date of the battery.
There is a mistake if these questions are not asked during maintenance:
-
How old are the batteries?
-
What is the production date?
📉 Result:
-
Batteries nearing the end of their lifespan go unnoticed.
-
UPS will cause problems again shortly.
6️⃣ Not Checking Connections and Terminals 🔌
During maintenance:
-
Just look at the battery
-
Cables and terminals are skipped.
This too:
-
Warming
-
Voltage drop
-
Sudden interruption
It creates a risk.
📌 A loose connection can render even a perfectly good battery useless.
7️⃣ Ignoring Environmental Conditions 🏢
UPS and batteries:
-
Very hot
-
Airless
-
Dusty
If it operates in these environments, maintenance is inadequate.
📉 High temperature:
-
It shortens battery life by 30–50%.
-
It strains electronic circuit boards.
8️⃣ Not reviewing alarm and log records 🔔
UPS systems often have problems:
-
Alarm
-
Log
as notified in advance.
If these records are not checked:
-
Repeated mistakes go unnoticed.
-
A malfunction would be a surprise.
9️⃣ Failure to Report Maintenance 📄
Saying "it's done" isn't enough.
After maintenance:
-
Test result
-
Battery status
-
Risks
-
Suggestions
If it's not in writing, the action is unproven .
🔟 Setting the wrong maintenance frequency
-
Checking your CCTV or server UPS once a year is ❌
-
Extending the maintenance interval when the battery is more than 2 years old is ❌
📌 Maintenance of critical systems:
It should be done more frequently and in more detail .
What is the common result of these mistakes?
-
UPS will not work during outage.
-
Camera recordings stop
-
The servers shut down.
-
Business and data loss occurs.
👉 And the sentence is always the same:
"We had a UPS, but it didn't work."
What is the correct approach to UPS maintenance?
✔️ Load and discharge test
✔️ Thermal camera inspection
✔️ Battery group evaluation
✔️ Connection and environment control
✔️ Written reporting
📌 Maintenance is a verification process, not a check .
