A battery pack ( 110 ) having a plurality of cells ( 103, 105 ) utilizes a pull up resistor ( 116 ) multiplexed between separate voltage supply sources ( 120, 122 ) and a single battery contact ( 106 ) to monitor individual cell temperatures. A plurality of thermistors ( 102, 104 ) are coupled in series between ground potential ( 108 ) and the single battery pack contact ( 106 ), each thermistor being coupled to one cell of the pack. Individual voltage divider circuits are formed for each thermistor ( 102, 104 ) as the pull up resistor ( 116 ) is multiplexed between the voltage supply sources ( 120, 122 ).
