1. A method, comprising:
- providing a plurality of contacts, each of the plurality of contacts for coupling to a respective one of a working electrode, a reference electrode and a counter electrode of a sensor;
providing a power supply including a rechargeable battery;
providing battery recharging circuitry operatively coupled to two of the plurality of contacts and the rechargeable battery, the recharging circuitry including an electrostatic discharge protection circuit; and
charging the rechargeable battery via the plurality of contacts when the plurality of the contacts are decoupled from the sensor;
providing a signal representative of an indication of charging the rechargeable battery when the plurality of contacts are decoupled from the sensor; and
suspending wireless data communication during charging the rechargeable battery.
