Abstract
Embodiments of the present disclosure provide a method and apparatus for testing a condition of a battery. In one embodiment, a testing instruction for the battery is received from a controller of a device. In response to reception of the instruction, the battery is caused in a testing mode in which the battery and a power supply of the device concurrently provide power to the device, a first voltage provided by the battery being greater than a second voltage provided by the power supply. A condition of the battery is determined by monitoring an output current of the battery. Through the method and apparatus of the embodiments of the present disclosure, consumption for battery test may be reduced without a need of interrupting operations of the apparatus.
