Abstract
A reusable battery indicator includes a voltage sensor, a communication circuit communicatively connected to the voltage sensor, an antenna operatively coupled to the communication circuit, and a connection mechanism having a connector and a retainer. The connector and the retainer are electrically connected to the voltage sensor, and the connector is adapted to be removably connected to a first battery terminal, thereby providing an electrical connection between the voltage sensor and the first battery terminal. The retainer is adapted to removably secure the voltage sensor to a can of a battery, thereby providing an electrical connection between the voltage sensor and the can of the battery. An electrical circuit is completed between the voltage sensor and the first battery terminal and between the voltage sensor and the can. The connection mechanism includes part of an electrical lock and key assembly.
