    let's say you have 3 types of batteries, 12V 7ah, 12V 7.2AH, and 12V7.5ah.

    what do these batteries translate to into the UPS va advertised on like a backups 700, or a backups 350? or, let's say you have a 350va UPS with a 12V battery, how many ah would it be rated at?

    thanks

    Go to APC's website - they have some great calculators on which UPS to buy based on your load and desired runtime.

    350VA / 12V * RUNTIME = AH

    Keep in mind that with 60Hz alternating current, the wattage is about 2/3 of the VA rating.
