It is not uncommon for a battery pack to have a thermistor and/or code resistor contact(s) to allow battery detection by a charger. Although these contacts can be changed based on the battery's environment, the battery pack will always have a B+ and B- contact for charge/discharge purposes. This invention will discuss how a battery can be detected by relying on battery voltage and a charger's discharge circuit.
