Abstract:
A remote control is powered by multiple batteries connected in series. The remote control includes a voltage comparison circuit configured to compare a midpoint voltage from a node connecting two of the batteries to a reference voltage. The remote control is able to determine if there is a non-uniform drain rate in the batteries based on the comparison.
