Abstract

A battery test unit for testing batteries while stored in a cassette-type package having an electrically conductive base sheet and a housing, mounted on the base sheet, forming a plurality of individual battery compartments. Each compartment stores an individual battery and has a contact access opening in its cover. The housing and the base sheet are arranged to store each battery with one terminal in electrical contact with the base sheet and the other terminal accessible through the contact access opening in the cover of each compartment. The battery test unit of this invention is a handheld, manually operated device comprising a body having a receptacle region for receiving the cassette-type package, a selector switch for selectively individually making electrical connection through the cassette access openings with one terminal of each stored battery in the corresponding cassette compartments, a meter for testing each battery selectively connected by the selector switch, and a main contact for making electrical connection with the cassette base sheet.

A battery test unit for testing batteries while stored in a cassette-type package having an electrically conductive sheet base and a housing mounted on the base, with said electrically conductive sheet base being accessible at the outside of said housing, said housing forming a plurality of individual compartments each for storing an individual battery and having a contact access opening in each compartment, the housing and base being arranged to store each battery with one terminal in electrical contact with the conductive sheet base and the other terminal accessible through the contact access opening, said battery test unit comprising:

a body having a receptacle region for receiving the cassette-type package;
main contact means in said unit and being positioned near said receptacle region for making electrical connection with the electrically conductive sheet base of a cassette-type package received in said body receptacle region for simultaneously making electrical connection to the one terminal of each battery in said package which is in electrical contact with said conducting base sheet;
movable selector means in said unit for selectively individually making electrical connection through the cassette compartment access openings with one terminal of each battery stored in the corresponding cassette housing compartments of the cassette-type package received in said body receptacle region;
meter means in said unit for testing each battery for metering the charge condition of the battery, said meter means being electrically connected to said selector means and to said main contact means;
and
indicator means in said unit associated with said meter means for indicating the charge condition of the individual battery with which said selector means is making electrical connection.
