UPS battery backup keeps equipment operational through short power failures and provides time to save data and perform orderly system shutdowns if faced with a prolonged blackout. It features a large internal battery that provides about 3 minutes of battery support for a full load (300 watts) and 14.6 minutes for a half-load (150 watts). During normal operation, incoming utility power keeps the UPS battery fully charged so that backup power will always be available if needed.
