The disclosed invention provides a system and apparatus for monitoring battery status and usage to facilitate battery protection, battery repurposing and battery maintenance. Wireless interrogation of a battery's location and key attributes provides efficiencies to manage the total lifecycle of an electric vehicle battery, whether installed in a vehicle or in an environment external to the vehicle environment. A wireless battery tether, combined with a wireless battery reader, a wireless battery gateway and a centralized battery monitoring server allows management of the high-voltage battery through its lifecycle.
