Whitepaper: Lifespan Of UPS Batteries
Depending on the application, the batteries in an uninterruptible power supply can consist of a single block or thousands of cells. 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, and operational voltages.
You'll also learn the most common conditions that influence 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.
