How Long Can UPS Last? Battery Life & Guide

A Uninterruptible Power Supply (UPS), a critical component for safeguarding sensitive electronics, relies heavily on its battery to provide backup power during outages. The runtime of this battery, therefore, determines how long can UPS last, a crucial factor for both home users and large data centers like those managed by Schneider Electric. Understanding the factors influencing battery lifespan, along with employing proper maintenance techniques as outlined in the manufacturer’s guide, is paramount to ensuring optimal performance and preventing data loss or hardware damage when the electrical grid falters.
