When the lights went out today I noticed my UPS battery didn't work. I checked the monitor and this is what I see:
As you can see it says the battery has 90% but when I pull the plug, it doesn't work.
Is there a way I can fix this or find out if the problem is battery or UPS?
This is my UPS model I bought this FEB 2012, so it's about 1yr8mo. I only noticed the problem now because it's only now there's been power interruption.
4Have you looked at the manual for a troubleshooting guide? They may tell you when to change the battery. Perhaps some information on the UPS would help us help you. – uSlackr – 2013-10-10T12:47:06.930
@uSlackr the manual only suggest that I charge the UPS for 6 hours which I will try later. – IMB – 2013-10-10T13:06:41.567
1Perhaps your equipment load exceeds the output of the UPS. Try unplugging your equipment and plugging in something like a table lamp. See if, and how long, it runs on the UPS. – HABO – 2013-10-10T13:17:44.097
@IMB I would contact the company and see if the unit its still under warranty. Your battery has clearly been used if it has lost 10% capacity in only a year. – Ramhound – 2013-10-10T13:36:14.377
1When testing a UPS do not unplug the UPS from the wall socket. That would also disconnect ground, and eliminates a safety feature to prevent shock. Instead connect the UPS to a power strip and that to the wall outlet. Use the switch on the power strip (which will maintain the ground connection) to simulate power loss. – sawdust – 2013-10-10T19:17:31.863
