Aside from paying a high price for a battery from the UPS maker, buy one with the same specs in a brand you know to be reputable for your area.
How do you figure that? The 9ah will run longer
Amp Hours basically gives a reference on how long a battery will run on a certain load, example, a 1amp load will run 9 hours on a 9ah battery and 7 hours on a 7ah battery. a 9 amp load will run 1 hour on the 9ah and 45 minutes or so on the 7ah.

And the capacity of the battery won't boost up the VA rating of a UPS, that is determined by the DC to AC circuits in the UPS. All you will get is extended run time.
Yes i heard same just like Zepher mentioning above! and if it does really extend the time so i would be more than happy...

The goal of a UPS is to keep your system running long enough after a power failure to be able to save your work and do an orderly shutdown. Seems like 8 minutes is plenty of time to do that. If you really want to be able to run for the duration of the power failure without interuption, you should look into a backup generator.
strollin i really agree with you and your right about 8 mins that it's enough time to shutdown the PC properly but in my country the power-failure does'nt happen once in a while coz it's going on daily-basis and on scheduled time and this becomes a real big problem when im gaming coz as soon as there's power out while gaming (where the whole pc is running on peak mostly) it sucks the life of the backup time within seconds.

On a more serious note you could use a car battery instead

Golf cart batteries would do a better job, they're heavier duty.

I'd consider a couple of 6V golf cart batteries in parallel, along with an appropriately sized inverter and a smart, 3-stage charger to maintain the batteries.

I can get them but my UPS does not support External Batteries and it is mentioned in the booklet that do not attach external batteries and you may damage the ups or something like that...

i also wanna know that my UPS running 2 12v batteries @ 24v probably so can i use 6v batteries lets say 4x 6v batteries with some good ah's?

If the power goes out on a schedule, wouldn't it make sense to shutdown the PC when it gets close to that time instead of waiting for the PC/UPS to die?
You can schedule a message to remind you and/or shutdown the PC with a scheduled task.

That would kinda fall under the external battery clause....but that might be what you end up doing anyway.....

I would go with the battery type that it is supposed to be. If you could attach an external It would likely pull to much amperage from the UPS's charging system since it would be a bigger and more powerful battery.
You could get a new UPS too.

That's why I suggested golf cart batts, inverter and charger previously. Those three items together would replace his existing UPS with a much heavier duty, homemade UPS. I have a similar setup for my RV, coupled with a Honda 2000W generator I can power all my electronic goodies in the RV as long as I have gas to run the genny to recharge the batts when they get low.
