UPS Battery Maintenance and Testing

UPS Battery Maintenance & Testing


UPS Battery maintenance programs by Sure Power provide essential diagnostics which help extend VRLA battery and wet cell battery life and help you avoid expensive downtime. Batteries are the lifeblood of your UPS or telecommunications system, the power source for your standby generators and may provide backup power for your switchgear. In the event of a power emergency, batteries will provide continued operation of your computer, voice and data communications systems – but only if they work.

You have control over most of the conditions that lead to battery failure. Common conditions include excessive cycling, improper charging, lack of temperature control, installation and manufacturing problems.

The key to ensuring the reliable operation of your battery backup is a comprehensive predictive maintenance and testing program. Typically sealed VRLA battery systems require annual maintenance according to IEEE-118. Flooded / Wet Cell battery systems are generally on a quarterly maintenance plan per IEEE-485.

Sure Power offers preventative maintenance contracts based on each company’s specific needs. A typical scope of work might include:

  • Clean tops of batteries, racking, cabinet, etc.
  • Measure and record float voltage readings
  • Measure and record internal readings
  • Re-torque all connections
  • Measure and record connection resistance
  • Measure room temperature
  • Measure cell / battery temperatures
  • Measure and record system settings including chargers, rectifiers and UPS
  • Measure and record cell specific gravities (If applicable)
  • Add water as required (Flooded cells)


After a UPS battery system is installed, periodic battery testing will maximize the lifetime of the system and identify potential issues to rule prevent unexpected problems. Ensure that your UPS system will deliver the protection expected from it by scheduling regular AC / DC load bank and battery load testing.
