BATTERY AND ELECTRONIC DEVICE

A battery and an electronic device are provided. The battery has at least one notch at an end of a protection board away from a battery cell. The notch has a first side wall and a second side wall opposite the first side wall. A first preset distance is present between the first side wall and an outer edge of one side of the protection board, and a second preset distance is present between the second side wall and an outer edge of the other side of the protection board. The first preset distance and the second preset distance are both greater than 0. Such design saves a design area of the battery, providing more space for arrangement of other components in an electronic device.
