ABSTRACT:
Battery capacity in a portable two-way radio is determined by measuring the voltage across the battery at predetermined time intervals and determining battery voltage slopes. Each battery voltage slope is compared with a previously determined battery voltage slope and the battery capacity is determined by analyzing the changing pattern of the battery voltage slopes.
