Autonomic battery reconditioning

A method comprising:

• controlling a rechargeable battery in an information processing apparatus driven by the rechargeable battery, by:
• acquiring a present full charge capacity that is a full charge capacity which said battery has at the present time, said full charge capacity being a capacity in a state where said battery is fully charged, and said full charge capacity being decreased by repeatedly charging or discharging said battery;
• acquiring information indicating a total amount of charge provided to said battery in a time period from a start time of using said battery until said present full charge capacity is acquired;
• and
• performing a battery management by fully discharging or fully charging said battery if the present full charge capacity acquired is smaller than an expected full charge capacity that said battery should have depending on the information.

Apparatus comprising:

• a rechargeable battery;
• a full charge capacity circuit, coupled to said battery, which acquires a present full charge capacity which said battery has at the present time, the full charge capacity being a capacity in a state where said battery is fully charged, and the full charge capacity being decreased by repeatedly charging or discharging said battery;
• a total charge circuit, coupled to said battery, which acquires information indicating a total amount of charge provided to said battery in a time period from a start time of using said battery until the present full charge capacity is acquired;
• and
• a first circuit, coupled to said battery, which performs battery management by fully discharging and fully charging said battery if the present full charge capacity is smaller than an expected full charge capacity that said battery should have depending on the information.
