UPS power goes off instantly as soon the external supply stops
I have a V-GUARD UPS (UPS-50E) which I have been using along with my computer for a quite long time. For a few months, its not giving me the stand by power to switch off my machine safely and the power goes off instantly when the external supply ends. I had a battery replacement couple of years back. What could be the reason for this to happen? I tried hooking the UPS to the wall power outlet for a long time and it didn't help. Even the "Backup Battery Low" indicator is not flashing when the UPS is switched on. Please can you advise any steps that I can execute towards resolving this?

In our office, I have had to replace UPS batteries AGAIN two years after I replaced the original batteries in the units. I had purchased the replacement batteries locally, so I don't know if the brand of replacement batteries was not as good as the original batteries or what. But your weak battery light is not flashing ... I would try a replacement battery (if it isn't too expensive) but I know that some of the older batteries are no longer used in the newer UPS units so if the problem wasn't the battery you are stuck with a new battery and nothing to use it for.
Also visually the batteries to see if they are cracked or bulging. If they are then you know the batteries are the culprit.
