Abstract: A battery pack in one aspect of the present disclosure includes a rechargeable battery, a rewritable nonvolatile memory, a write request receiver, and a write controller. The rewritable nonvolatile memory includes storage areas including a write-inhibit area. The write request receiver receives a write request and data from a charger. The write request includes a first address assigned to a first storage area of the storage areas. The data includes a first data element. The write controller executes a write process for the received data. The write process includes avoiding writing the first data element to the first storage area in response to determining that the first storage area is the write-inhibit area.

Abstract: A main body of a motor-driven appliance is configured such that a plurality of battery packs are attachable thereto. Each of the battery packs contains a battery. The main body of the motor-driven appliance acquires, from each of the plurality of battery packs, discharge capacity information indicating a discharge capacity of the contained battery. The main body of the motor-driven appliance sets at least one control parameter to control discharge from a power source to a motor, in accordance with at least the discharge capacity information of a battery with a lowest discharge capacity, among the acquired respective discharge capacity information.

Abstract: A charger of the present invention may include a plurality of battery connection parts to which battery packs can be connected to charge, with each battery connection part having an indicator. The indicators may be configured such that when charging is expected to be completed more quickly in a first battery connection part compared to a second battery connection part, the indicator of the first battery connection part is displayed differently from the indicator of the second battery connection part.
