Assuming the load has remained the same, it seems like the battery has lost its capacity. If it is within warranty period, get it replaced. If not, still replace at own cost.
As a general rule, be very careful with procuring batteries. Many dry/SLA batteries imported here by various traders are at the end of their shelf life and near expiration. Unless you can be sure of legitimacy of the distributor/agent and the manufacturing date of the battery, avoid them. Also, due to our excessive load shedding scenario, there is too much battery cycling which results in early loss of capacity. In the cost of a single SLA battery, you can have two local wet batteries (usually recently manufactured/assembled) from known brands having warranty coverage. Plus, you can replace them when they loose capacity with fresh units in the same total cost of an equivalent SLA setup. Maintaining them and periodically checking and topping up battery water is however a PITA.
Absolutely right you are, infact, and I am sure Farhan will also cofirm to this when I say, when I was buying the battery, I had detailed convo with farhan about shelf-life / manufacturing date about SLA batteries and relate stuff. and I knew about the pros & cons of SLA & normal batteries but I guess the thought of having a "Maintenance free battery" clouded my judgment cause that thought made me forget my location and the kind of mind-set I am dealing here with.
On top of that, I wasn't able to buy from farhan as I already paid another dealer here (long story). Now I think if the issue is with battery, it could only be due to lack of confirmation of the shelf-life of the battery plus I also think battery was already in use for quite some time... Had I been able to buy from farhan, could have been a different story.
And most funny thing is, the warranty period of the battery which was of 6 months, has expired 3 days ago
Anyways, I'll see what I can do once the problem is pin-pointed and if its the battery, I will surly go for a normal wet battery if I can't confirm the shelf-life / manufacturing date.
Thank you for replying...

Very nice... Aise zaror help mile gi.. ::Middlefinger::
1 - get a PROPER Dc clamp voltmeter, preferably a Uni-T brand.
2 - when ups shows dead battery BEFORE (while beeping) and AFTER it shuts down, check battery terminal voltage.
3 - when dead and starts charging put the clamp on the red wire to battery and measure DC amps.
4 - when ups says battery full check terminal voltage.
5 - report all readings here
This D/D will easily identify which thing is at fault.
PS: screw you still Bayatch.
I will get the voltmeter tonight. I will test as per instructed and report back. BTW I am assuming by "terminal voltage" you mean the + and - terminals of...... the battery...?
