    Our SmartUPS 1000 fails every fortnight. The alarm sounds and the output fails. It switches over to battery, which drops immediately and the attached equipment powers off. Photos taken at the time show The overload and replace battery indicators lit - see attached.

    The ups power needs to be unplugged. When plugged back in the equipment powers up and the battery recharges in a few hours.

    I understand my predecessor replaced the battery within the last year.

    A manual test does not cause this issue.

    Can anyone advise me the way to resolve this please?

    Hi Malcolm - 

    that LED indicates an Overload. What do you have connected to the UPS? How many LED's are normally lit on the left hand side column?

    Hi Liam,

    From what I can see the load is a “small” HP server (+ monitor that is usually off), BT broadband modem, router and a couple of network switches.

     I can’t remember the lights. I will check when I am next on site which will be Monday and post then.

     I just spoke to the office. In normal operation none of the lights on the left are lit.

    When the batteries were dead in one of my older APC units, it would drop the load every fortnight when it went to do the self test.  Quite annoying because the UPS caused more outages than it prevented.  I was able to work around the problem by changing the settings to disable the self test, but of course the batteries were still dead so in a power outage everything switched off immediately.  But at least it stopped the extra outages until I was able to replace the batteries!

    As the batteries were dying though, it got to the point where they could sustain a small load like a light bulb, but they'd switch off when powering anything bigger, owing to the fact that the apparent capacity of lead acid batteries reduces as you draw more current.  So my guess is that your batteries are about to die.

    If you are sure they were only replaced a year ago (check the battery replacement date in the UPS config) then they could have just been a bad/cheap batch, or new old stock.  If you bought from a reputable supplier maybe you will have warranty options you can explore, but warranties around one year or longer aren't common for batteries, going to show just how long they are expected to last for!

    In the office during normal (mains powered) operation none of the left hand lights are lit. 

    The user guide seemed to suggest they only light when the ups is providing power, so I briefly turned off the mains power (I didn’t want the server to go down). None of the left hand lights lit then either.
