1. A battery type detector for determining which type of battery is coupled to a battery charger, the battery and the battery charger each having a housing, the battery type detector comprising:
- means for producing a predetermined one of a plurality of sense levels corresponding to a battery type comprising;
a regulated voltage,a first resistor disposed within the battery charger housing, anda second resistor having a resistance selected in accordance with said particular battery type and disposed within the battery housing, the battery housing having positive, negative, and sense terminals disposed thereon, and said first resistor coupled between said regulated voltage and said sense terminal and said second resistor coupled between said sense terminal and said negative terminal;
means for detecting said one of a plurality of sense levels; and
means, responsive to said means for detecting, for enabling a predetermined battery charging control in the battery charger corresponding to said battery type.
