A pair of electrical connections are located on the casing to electrically connect the battery package to a load. The converter conducts and the cell discharges only when a load is present across the electrical connection.Field of SearchDouble-ended (i.e., push-pull), self-oscillating typeWith automatic control of the magnitude of output voltage or current Double-ended (i.e., push-pull), separately-driven type With automatic control of the magnitude of output voltage or current With voltage multiplication means (i.e., V out > V in) Including semiconductor means For rectifying Double ended (i.e., push-pull) type Separately driven |
