UPS is not very suitable for this application. The batteries inside are usually SLA (sealed lead-acid) and discharges (say below 50%) will reduce their life significantly (I would be surprised if they last more than 100 cycles). Even discharging them below 80% will start causing a damage to the battery.
Also the voltage conversion losses are greater as the voltage gets converted from DC to AC (in the UPS) and then back to DC.
