What Is Typical UPS Lifespan?

How long is a home UPS (eg 1000VA) supposed to last?

I notice mine seem to last 2-3 years after which the battery doesn't seem to hold charge any more.

Are you supposed to do some kind of maintenance on them to make them last longer?

Thank you

    You're supposed to replace the battery/batteries as they wear out.

  • That seems pretty typical for a lead acid battery in these, the trick is to always have a (and easily) replaceable battery as an option when you purchase.

  • I remember years ago when you had double banks, it would be recommended to discharge one bank at a time every 180 days …

    Don't think that is expected anymore.

  • Depending on usage/brand/quality of UPS and battery.
    2-3 years is normal. 5 years if you're lucky.
    A good UPS should have a software that you install on your PC to do the auto diagnostic. It will tell you the battery status and if it needs replacing.
    I've supplied APC, Eaton, and CyberPower for work. CyberPower is surprisingly much more reliable even though it's a lot cheaper.

  • Just stumbled on an old (2011) post

    The best way to achieve the most life out of your UPS batteries is to ensure the unit is well ventilated and kept cool, try to leave enough gap for air to flow around the unit.

    ………and 2-3 years was a popular last time,

    and (seen this myself) once battery is old everything may test and look OK but power will go off and instantly UPS may fail you ie once near gone in time then replace.

  • A UPS will fail one week before you actually need it.

    You'll ignore the warning, thinking "I'll replace the batteries at the weekend".

    Then it turns to poo on Friday….

  • It depends on what your needs are in an UPS.

    I found replacing batteries in my PowerWare 5110, they never lasted as long as the original, and they weren't cheap E-Bay ones either.

    My last UPS was a good 7 years old, and the battery was good for about 30 seconds before it shut down.

    When I built my new PC late last year, I decided it was time to buy a new, more powerful one. I'll probably replace the battery in it after a few years, though, as it was considerably more expensive than a replacement battery.

  • I'm really intrigued. Erm … wtf is a 'UPS'?

    • United Parcel Service

      • mmmyeah, hilarious brutes … I seriously actually didn't know what 'UPS' stood for in this context; and I would guess that's the same for the majority of OzBargainers. It's best not to use uncommon abbreviations in titles, because then no one can learn anything from your post, unless they already know a bit about it (i.e. are familiar with some obscure acronym). It's a bit like me posting:

        'Using a GER in my PTX for 2 hours straight; How to get the best DER/pg?'

        • This is posted in a computing sub forum, so it's a commonly understood acronym for people who have basic experience with computer hardware.
          The same way that you would use terms like HDD , RAM, CPU, USB , without needing to expand the acronym.

          • @eckorock: I get your general point e-rocks. Do you get mine though? What I am suggesting is that it would be nice if regardless of the actual forum (or 'sub' forum?) posted in, full terms were used in the title; so that peeps who are not educated/knowledgeable about the subject matter can actually LEARN from the forum post … because they are initially informed as to what it is actually about—instead of being 'baffled from the outset' because jargon has been used in the title, instead of full/explanatory terminology. The same general principle is held to be valid and largely adhered to across the more reputable (and 'high-impact') scientific literature for these exact reasons.

            Happy trails

            • @GnarlyKnuckles: Understand your point and appreciate where you're coming from.

              An expanded acronym in its own doesn't always help to explain what the thing is.

              Eg Universal Serial Bus
