Whitepaper: Lifespan Of UPS Batteries
The batteries in an uninterruptible power supply can consist of a single block or thousands of cells, depending on the application.
But without a well-maintained, properly functioning battery system that performs when required, a UPS is practically worthless.
In this whitepaper, we take an in-depth look at UPS batteries and offer some practical steps on how best to manage them.
It begins by taking a look at the difference between a UPS battery’s stated design life and its actual service life. Internationally-recognised guidelines from EUROBAT state that a battery is considered at end of service life when capacity drops below 80%, which is why industry best practice suggests replacing 10-year design cells in year 7 or 8.
The Lifespan Of UPS Batteries whitepaper goes on to explore the main factors that impact the length of battery life. These include ambient temperatures, the frequency and depth of discharge, operational voltages, and the period batteries are left in a discharged state.
Readers will also learn about the most common conditions that influence on battery life, such as grid corrosion, thermal runaway, and sulphation.
In addition, the whitepaper offers an overview of battery maintenance and how you can prevent premature battery failure. This includes a guide to some of the most effective battery tests (i.e. impedance testing or load bank testing), along with some top tips about optimal operating conditions and battery care systems.
