A lithium battery is connected to the uninterruptible power supply. A voltage drop protector (VDP) is connected to the lithium battery and connected between the commercial power source and a device of a second type. Tolerable error thresholds for a voltage and frequency required for the device of the first type are smaller than tolerable error thresholds for voltage and frequency required for the device of the second type.
