1. A service tool for programming an in-vehicle electronic battery monitor to register batteries of an automotive vehicle with the in-vehicle electronic battery monitor, comprising:

  • an operator input configured to receive operator entered battery parameters related to battery parameters specified for the automotive vehicle;

    a sensor configured to couple to a storage battery in the automotive vehicle and sense an electrical parameter of the storage battery;

    I/O circuitry configured to couple to the in-vehicle electronic battery monitor, to thereby provide battery registration information to the in-vehicle electronic battery monitor associated with the storage battery and the in-vehicle electronic battery monitor of the type used to monitor the storage battery of the vehicle during operation of the vehicle based upon parameters of the storage battery stored in a memory of the in-vehicle electronic battery monitor and communicate with a controller of the vehicle using a databus of the vehicle; and

    a microprocessor configured to perform a battery test on the storage battery using the sensor and determine measured battery parameters based upon the battery test, compare the measured battery parameters with the operator entered battery parameters to thereby verify that the operator entered battery parameters match the measured battery parameters and further configured to store battery registration information in the memory in the in-vehicle electronic battery monitor through the I/O circuitry as a function of a result of the battery test and thereby verify that the battery registration information matches the storage battery of the vehicle by storing parameters of the storage battery in the memory of the in-vehicle electronic battery monitor to reduce errors in measurements of the storage battery performed by the in-vehicle electronic battery monitor.
