1. Computer-executable instructions for determining active and standby battery power information, said computer-executable instructions comprising:
- a first program code for initializing at least one variable for use in performing calculations in said computer-executable instructions;
a second program code for reading raw electrical power data collected by a battery data collector and converting said raw electrical power data to active and standby battery information, said second program code using said at least one variable initialized by said first program code to read and convert said raw electrical power data;
a third program code for resetting a battery fuel gauge data to zero, said battery fuel gauge data a part of said raw electrical power data, said third program code called before said computer-executable instructions terminate as a result of full battery power drainage;
a fourth program code for resetting said battery fuel gauge data to completely full, said fourth program code called after said raw electrical power data indicate a battery power charge from partially empty to completely full; and
a fifth program code for resetting an expected battery full reading, said expected battery full reading a part of said raw electrical power data, said fifth program code called after said raw electrical power data indicate a battery power charge from completely empty to completely full.
