User interface for rechargeable batteries

A method for indicating a state of a rechargeable battery, comprising:

• determining at least one of a charging status and a state of health of the battery with a processor disposed within a housing of the battery;
• displaying on a plurality of visual components positioned on a surface of the housing of the battery, a plurality of visual cues indicating at least one of the charging status and the state of health of the battery;
• and
• providing an actuatable switch on the surface of the housing of the battery, an activation of the switch causing the plurality of visual cues to be displayed on the plurality of visual components.

A rechargeable battery configured to be removeably inserted within a mobile device, comprising:

• a battery housing having an external surface including a user interface region that is exposed when the battery housing is inserted into the mobile device, the user interface region comprising a plurality of visual components;
• a battery cell within the battery housing, the battery cell having a charging status, a state of charge, and a state of health;
• a processor disposed within the battery housing and configured to communicatively couple to an external device, wherein at least one of the processor and the external device are configured to determine the state of health of the battery cell;
• and
• a switch coupled to the plurality of visual components, activation of the switch causing a plurality of visual cues relating to at least one of the charging status and the state of health of the battery cell to be provided on the plurality of visual components;
• wherein the state of health corresponds to whether a tested capacity of the battery divided by a capacity metric of the battery is below a predetermined threshold.
