How does an APC battery backup work?

A standby UPS resorts to battery backup power in the event of common power problems such as a blackout, voltage sag, or voltage surge. When incoming utility power drops below or surges above safe voltage levels, the UPS switches to DC battery power and then inverts it to AC power to run connected equipment.

What happens if UPS is turned off but is still connected to a plug for 24 hours?

Yes, it will shorten the life expectancy of its batteries. Every night, with the UPS unplugged, the batteries self-discharge. Every day, when you plug the UPS back in, the batteries have to charge back up to compensate for the self-discharge. This daily partial discharge, full charge cycle will reduce the battery life.
