APC UPS VS Microtek Double Battery

MY MARKET EXPERIENCE:

After obtaining advice from members here i went to Ganesh Chandra Avenue for purchase of UPS in Kolkata (I decided finally that i will purchase either APC UPS of 800 VA or if budget permits depending on cost 1 KVA)....

PROBLEM:

The shopkeeper said that since APC UPS is having single battery of 800 VA or say 1 KVA; the time UPS can provide my system backup is same irrespective of weather its 500 VA or 800 VA or 1 KVA...

Instead he suggested me microtek double battery 800 VA and suggested that i should go for it...as it has double battery and its battery which doubles backup time and not VA...

WHAT I NOW WANT:

I still love premium products (of course within my range) and therefore want to purchase APC say 800 VA but the shopkeeper says that since all APC UPS in India are having only one battery its going to give same 15 minutes backup say be it 500 VA or 800 VA or 1 KVA...

WHY I AM PUZZLED:

I hardly understand all this complex watt; volt; amperage etc. My guess was that if i go for say 1 KVA insstead of 500 VA I will get double time from same APC UPS...

CLARIFICATION NEEDED:

Can anyone plz say what this shopkeeper is saying is true or what exactly is the logic....I am utterly confused...???????????????????????????????????????????

A LITTLE BACKGROUND: (reminder)

P4 3 Ghz
3*512 MB RAM
CD DVD R/RW
HDD 160 GB three partitions
HDD 80 GB two partitions
windows xp operating system / windows advanced 2000 server
motherboard intel 865 GBF

(system in AC room)

The application that I currently always use in SAP using Oracle database on windows server 2000 when using 160 GB HDD...

At other times normal surfing using windows xp professional with 80 GB HDD...

WHY I NEED UPS

I need Ups to ensure that when I am using SAP with oracle database...there is no unexpected power outage as it may corrupt SAP software...which is a headache to get installed again...

PLz reply urgently as UPS is really needed considering 5-10 minutes powerout at 2-3 times a day...

thanks again....

Hi Sunandoghosh

I don't think that having a single battery would affect the backup time. The only benefit you may get is that if one goes bad you can still run the other one albeit for a samller amount of time. This may also be of some use when hot swapping the batteries which doesn't seems such an important issuse considering your situation.

So basically if you run 800 VA on lesser load the backup time would be increased and 15 mins of backup time irrespective of the load seems incorrect.

Instead of microtek you can go for the powerware 500 va model, with 1-4 batteries. They will deliver the ups to you at home I think.
Also you may try smartpower 1kva model, which produces sine curve output like normal AC connection. Smartpower's factory is located at Kolkata and the 1kva model has got a pc interface(optional maybe) like the apc.
Finally, I don't think the person gave you correct information that the 1kva model carries the same battery as the 500va model, you may do a little research at the apc india website.
btw, why don't you have an online chat with apc guys at the apc india website?

Theoritcally, what your dealer is telling you, is correct, the load capacity of UPS dosen't tell you how much backup its gonna provide, but normally a a more higher capacity battery would be used in 1 kVA UPS than a 500VA UPS, so you get a higher backup time.
And don't trust those dealers, they only tell those you to buy those products in which they get higher margin.Best thing would be to compare the battery capacity of 2 UPS (usually given in Amp-Hr) given in specfication sheet of UPS, to find out which would provide more backup.
