Abstract
An apparatus for monitoring the condition of a battery. The apparatus includes a battery clip that is used to secure a battery to a battery connection and a battery monitoring IC. The battery monitoring IC takes a “load vs. no-load measurement” and the results are recorded in a register. When the battery reaches a certain low voltage state, register bits are set and an output is generated. Furthermore, the exemplary embodiment includes a removal detection circuit for detecting removal and replacement of the battery and for preventing voltage floating on the battery output line.
