Abstract: A battery pack in one aspect of the present disclosure includes a battery and a controller provided with a counter value. During discharge of the battery pack, the controller calculates an addition value in accordance with a total number of use of the battery pack under a specified condition. The controller updates the counter value by adding the addition value. The controller prohibits the discharge of the battery pack in response to the counter value reaching a protection threshold.
