ABSTRACT:
An electric storage battery is provided having a monitoring device for indicating the state-of-charge of the battery and particularly indicating whether a discharged battery is healthy and capable of being recharged or unhealthy and impending on a state of failure. The monitoring device achieves the foregoing by testing the open circuit voltage of the battery and determining if the voltage of the battery drops below a first preset value after application of a load and subsequently fails to rise above a second preset value after the load has been removed. Also, the monitoring device for the battery includes the capability of sensing when the battery has been placed into a system such as an engine system for an automobile and in response thereto modifying testing certain parameters. Preferably, the monitoring device is made integral with the battery case by providing a receptacle for receiving the device and a pair of connecting arms at least partially embedded in the battery container or cover.
