What is the main factor that determines the performance of a UPS? Is it the VA rating, the number of batteries or something else?

Someone recommended a friend of mine to buy a "double battery" UPS as it supposedly gives more backup time than single battery UPS no matter the rating. Is this true?

look at VA rating of the UPS and get decent brands like APC.

^Does the number of batteries has nothing to do with performance?

Quality of battery determines the backup time. UPS rating determines the max amount of load that can be given to that UPS.

Yes, battery quality and VA, and of course APC.
