Why does the battery voltage exceed the nominal battery voltage rating?

The battery voltage exceeds the nominal battery voltage rating. It solves automatically after two minutes or a little bit more. How to solve this? This error could be caused by the battery itself, or an issue with the UPS. We would need to look at data and event logs, and look at the age of the UPS and battery.

What is a terminal voltage in a cell?

Terminal Voltage The most identifiable measure of a cell is the ‘terminal voltage’, which at first may seem too obvious to be so simple. In fact, the terminal voltage can change dramatically as a cell goes through charge and discharge cycles. The ‘nominal voltage’ is what the chemists tell us the cell should produce with zero current flowing.

How efficient is a lead-acid battery?

A lead–acid battery at first had an efficiency of about 75%, but thankfully has improved with efficiencies to around 95% with some technologies. Final Voltage The term ‘final voltage’ designates the minimum useful and accepted voltage of a cell or battery at various rates of discharge.

When to stop a battery test?

Although the main criterion to stop a test is when the battery terminal voltage reaches the end of discharge voltage, which is obtained from the product of the end cell voltage and the number of cells, not all the cells discharge equally and the deeper they discharge, the faster the voltage will drop.
