Technical FAQs 4

How long does an uninterruptible power supply last?

Like all other IT equipment, an uninterruptible power supply (UPS) has a finite lifespan. The average expected lifecycle of a UPS is eight-to-ten years. The batteries typically need to be replaced at least three times during that lifespan. Of course, once a UPS reaches the end of its lifespan, it should be replaced to mitigate downtime.

What are uninterruptible power supply hours?

Uninterruptible Power Supply hours refer to the duration a UPS can sustain power to connected devices during an outage. This time can vary widely based on several factors, including battery capacity, load requirements, and the UPS’s efficiency. Knowing how to calculate this can help you select the right UPS for your needs.

How long can a ups last without power?

Discover how long a UPS can last without power—from 1 to 8 hours! Learn about UPS battery life, runtime, and factors affecting performance.

How do you choose an uninterruptible power supply?

When choosing a uninterruptible power supply, IT teams can evaluate two criteria. One is the life of the unit itself – up to ten years. The second consideration is batteries. Every UPS unit has a battery, which as mentioned, must be replaced up to three times.
