    Hello.

    After 9:00 AM PDT this morning, the planned almost all day power outage occurred. I was away in the kitchen from my room when the power outage struck. After a minute of walking fast back to my room to check to manually shut down my two old desktop PCs, it was too late. I heard a loud nonstop beep from the old APC Back-UPS XS 1500 (model: BX1500G) UPS (started using 8/27/2012 and battery's date shows 5/17/2012); that was still running including its loud fan. I also saw the UPS' front small status screen saying F01.

    According to my quick Google searches and manual, F01 means On-Battery Overload. How is that possible if there were no problems with flowing power from my room's wall outlet? It seems to only happen when there is no power from the wall outlet. Is 400 watts (45% load from two desktop PCs + a 23.6" 1080 LED widescreen monitor -- see http://zimage.com/~ant/antfarm/about/MyComputerStuff.txt for the full details) too much for the old battery? Do I need a new one?

    I tried running PowerChute Personal Edition v3.0.2's tests with it after my power was restored. No problems.

    Thank you in advance. :)

    hi Ant , your battery has more than 5 years , the recommendation is change them every 3 or 4 years maximum , probably the  F01 error came from bad batteries .

    when you change them don't forget to put in powerchute the new date of batteries , 

    regards,

    If the batteries are bad, then shouldn't had its tests failed from both UPS' automatic internal and Windows' PowerChute's tests?

    probably they are not totally dead , but when the batteries are old the acid inside them starts to dry causing it to short-circuit in the battery or fail to deliver voltage ramdomly , so maybe the test don't detect it yet , but soon it will do ,

    OK, I did some brief testings this morning with my UPS since I could reproduce the issue easily:

    Total watts used by 2 PCs + 1 monitor = ~425 (UPS failed with F01 overload & battery shutdown)

    Linux/Debian PC + 1 monitor = ~113 watts (UPS stayed up & battery power working)

    Windows PC + 1 monitor = ~324 watts (UPS failed with F01 overload & battery shut down)

    So my Windows desktop PC is sucking up a lot of battery power for UPS to fail. :( So a new battery will fix this problem?

    Thanks. I'll plan to buy a new APC RBC124 UPS Replacement Battery Cartridge for my APC Back-UPS XS 1500G BX1500G from https://smile.amazon.com/APC-APCRBC124-Replacement-Cartridge-SMC1000-2U/dp/B004F08NSM for $55.45 soon (apc.com web site shows it $70 and out of stock! :(). :)

    Also, I ran more tests from PowerChute after fixing its misdetections of my UPS model as shown in my http://forums.apc.com/spaces/4/back-ups-surge-protectors/forums/general/81530/how-do-i-reset-apc-powerchute-personal-edition-v3-0-2-after-switching-to-a-different-apc-ups/1 forum thread.  I noticed UPS took longer to do its tests. They passed again with both connected PCs and 1 monitor. FYI:

    OK, I got the battery replaced but how do I know how old these are? I saw no labels or anything on them. :(

    I also just tested its new battery by unplugging its power AC cable from the wall outlet after replacing it almost 12 hours later. No battery overload and shut down like the old battery. Now, I will need to recycle the old battery by dropping off at a local store soon.

    you can know the exactly date of the batteries normally for serial number , you need to ask the maker, he will tell to you how to read the serial number of them ,
