UPS battery replacement
Batteries are a consumable part of a UPS. As capacity falls, the UPS may continue indicating normal operation but fail to support the load for the rated runtime during an outage.
PES POWER diagnoses and replaces batteries in UPS from any manufacturer.
How replacement works
- Diagnostics: we measure each battery’s capacity and internal resistance using calibrated instruments — a Kulon capacity indicator and a Fluke BT520 battery tester.
- Report: we show which batteries have failed and whether the entire string needs replacement.
- Selection: by bus voltage, capacity, dimensions and terminal type.
- Replacement: through bypass without interrupting the load where possible.
- Verification: discharge testing and delivery of a measurement report.

Frequently asked questions
How do I know batteries need replacement?
Runtime has decreased, the UPS reports battery warnings, or batteries are swollen.
Can only some batteries be replaced?
This is not recommended: new and old batteries in one string operate unevenly and fail faster.
Do you replace batteries in other UPS brands?
Yes, we work with UPS from different manufacturers.
How quickly can an engineer visit?
Starting from one day after the request.
