UPS systems - Battery Runtime Tests
70% of all UPS system failures are battery related so detecting any possible damage to the battery system is crucial for effective monitoring of the same. You need to observe the temperature, voltage, and current under load conditions for battery-runtime tests. You can continuously check the battery cell either manually or with a cell monitor. If the battery string no longer provides designed discharge time or 80% of the rated capacity, then you know it's time for full battery replacement. We would suggest that you regularly monitor your UPS system to facilitate its smooth running.
