Okay - not so much a 'repair' as just required maintenance... In this one I have to replace the battery in my Uninterruptible Power Supply to get it back in service. I take the opportunity to open up the UPS and show the insides while I get the old battery out and get a new one in. Enjoy!

    Well my APC UPS takes two SLA's. At $15 each, it's still cheaper than another unit.

    I cannot seem to find UPS batteries that last more than 4-6 months. Years ago, I could buy those batteries and they would last 3-5 years. Can you , please, recommend a solution?

    I'm an electrician in a hospital with several hundred UPS devices but no program to keep track of them. Departments buy them as they please but never take the trouble to connect with the electrical department about what they bought. The electrical department is just me. When they fail if it's just batteries I replace them. If not I don't have the time to spend trouble shooting them so I just toss them out. Of course everybody complains that is wasteful but I'm the only electrician and there are 25 buildings and 1200 employees, I already have my hands full. Furthermore many UPS units aren't worth repairing because they are so poorly made.

    I'll need to research this a bit more, but we have quite a few UPS's that still do not perform correctly after we've switching out the old batteries for new.

    I replaced the battery in my UPS and it charged up to 13.42 volts and does put out 122 volts but the low voltage LED lights up and it beeps while using it. New battery. Any idea why the low voltage led would light?

    Whereโ€™s a good place to get the replacement battery?

    Hi Fran, looks like I have the same model of UPS, Can I use a 12V 34W battery instead of the 12V 35W battery?, this is because I can't find the exact replacement battery in my country, thanks in advance.

    I just changed the batteries in my 3000VA UPS. It weighs 50 kilos or 110 pounds.

    I think 'teardown' might be a bit of embellishment.

    The batterys are intends by regular replacement. All two years is replacement, in hospitals every year. But hospital ups, as for sugery, hold two batterys. If electricity goes and one is empty ups work anyway. And you change one battery the other keeps inside.

    Ups. Basically a battery charger inverter and a relay….. electrical supply houses are the best sourse for inexpensive batteries

    i think you should put the positive on first less chance of sparking in my experience anyway

  15. Avataaar/Circle Created with python_avatars Gmotion EDC says:

    Awesome. Most people would have thrown it away instead of getting another battery!!

  16. Avataaar/Circle Created with python_avatars Mike Fochtman says:

    Well my main computer is a laptop, so I don't plug that into my UPS. But my cable modem and router are on a UPS. Unfortunately, UPS doesn't last as long as my laptop battery, so I lose internet after a while.

    "Reverse thread method" So great to see someone else understand that!! I've seen so many folks 'double-thread' plastic holes and the screw threads don't hold worth a darn. Nice video.
