    Reviewed in the United States on June 24, 2023
    Verified Purchase
    This battery is a perfect OEM replacement for the suggested models and is much cheaper than replacing the entire UPS unit itself. I have quite a few UPS's around the house and save a lot of money every few years when the batteries need to be swapped out by purchasing this replacement battery, not to mention the waste savings by not throwing out the entire UPS units. I can usually get 2-3 years of constant use out of these batteries which is typical for a battery this size with 24/7 usage.

    My UPS had the faulty chirp of a dead battery. Although more expensive that 3rd party batteries I chose APC because they offer free recycling so I wasn't stuck with a big heavy battery to dispose of! Dead easy to swap out and worked a charm!
