Abstract

A battery cover system provides secure attachment between an electronic device and a battery terminal. A housing element includes a connector attached to the housing element and configured for electrical attachment to a battery terminal. The housing element also includes an electronic device attached to the housing element and to the connector. The connector may thus be attached to the battery terminal to provide a secure electrical contact throughout the life of the battery.
