Battery pack
First Claim
1. A battery pack configured to operably couple via a plurality of electrical terminals to a battery charger, the plurality of electrical terminals including a positive voltage terminal and a negative voltage terminal, the battery pack comprising:
- a plurality of designated terminals configured to operably couple to the battery charger, such that the plurality of designated terminals exclude the positive voltage terminal and the negative voltage terminal and wherein a number of the designated terminals are connected to a reference voltage and the number of designated terminals connected to the reference voltage determines an attribute of the battery pack.

Abstract
A method is provided for identifying a battery pack that is operably coupled to a battery charger. The method comprises: measuring voltage at a plurality of designated terminals of a first battery pack while the battery pack is coupled to the battery charger; determining how many of the designated terminals are connected to a reference voltage, such as battery positive; and identifying an attribute of the battery pack based on how many of the designated terminals are connected to the reference voltage.
