content: No, what sort of UPS do you have?Most things which work off a single AA battery don't use much power, so it makes sense to just use a decent quality alkaline battery.

content: Search for "AA battery eliminator" and you'll find lots of dummy AA cells with a lead. Check the voltage output as some of them look to be > 1.5V as they also come with a dummy cell with nothing inside.

content: I would step it up, and just do 18650's if you don't want to use lead acid batteries. You can't just stick those in any UPS though... it would need to be purpose built with a balance charger.
