Our History

Cadex Electronics Inc. was established in 1980 in Vancouver, Canada. Isidor Buchmann, Founder, President and CEO, recognized that the full potential of nickel-cadmium batteries was not being achieved and developed a battery analyzer to exercise and rejuvenate them. In its early days, the company operated under the name Buchmann Enterprises Inc. and all activities were conducted in a small room of the founder's residence. In 1985, after the registered trademark for the name Cadex was granted, the company changed the corporate name to Cadex Electronics Inc. Cadex is derived from "CADmium-EXerciser."
