Cadex Electronics Inc. was established in 1985. Isidor Buchmann, the founder and CEO recognized that the full potential of nickel-cadmium batteries was not achieved and developed battery analyzers 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."

Moving was nothing new for Cadex. “We have been packing and unpacking ever since I started the company in my house in 1980,” says the founder Isidor Buchmann. “Our frequent moves are not caused by poor planning but growth,” he quipped. The current address in Richmond, BC, is our 6th location, each move doubling and tripling the size.
Cadex engages in a partnership with Motorola to manufacture battery analyzers for distribution through Motorola's global network. In the same year, Mr. Buchmann is selected as a finalist in the Entrepreneur of the Year program.
Cadex reaches an agreement with Medtronic Physio-Control to design and supply intelligent chargers/conditioners for defibrillators.
Cadex achieves international market recognition with a customer base in over 100 countries. The company receives the prestigious British Columbia Export Award.
Cadex publishes the first edition of Batteries in a Portable World – A Handbook on Rechargeable Batteries for Non-Engineers. This popular book describing the basics of batteries and what the user can expect led to many subsequent releases in 2001, 2011 and 2016.
Cadex introduces the C7000 battery analyzer featuring the innovative SnapLock™ Battery Adapter system. This analyzer becomes the company's flagship and establishes a new global standard to which competitive products were compared.
As part of a five-year program for a US defense project, Racal Communications, now Thales Communications, commissions Cadex to build intelligent chargers and battery reconditioners. Cadex receives several awards, including two Supplier Recognition Awards for Outstanding Performance.
To accommodate a growing diversity of batteries, Cadex releases the first fully programmable battery analyzer. The Science Council of British Columbia and the National Research Council of Canada assist with funds. Interchangeable battery adapters configure the analyzer to the correct setting; a menu function allows reprogramming.
The four-station Cadex C2000 provides a low-cost alternative to the modular C6000 system. Batteries that fall below the set target capacity are automatically reconditioned with the AUTO program. Additional battery service programs are PRIME and CHARGE. The battery stations are pre-configured and cannot be changed in the field.
The Government of Canada awards Cadex with funds to assist in the development of a new battery analyzer system. The modular Cadex C6000 accommodates 16 Slave Modules to process 64 batteries unattended. The options include printer and bar code scanner.
A private company commissions Cadex to develop and manufacture a microprocessor-based fast-charger for the End-of-Train Unit. The ETU is a telemetry system that replaces the caboose on a freight train. This charger technology forms the basis for other Cadex products.
The modular Cadex 550 services three batteries simultaneously; ten with the extension unit. The detachable Slave Modules are custom-built for each battery type. The Cadex 550 sold reasonably well and became the workhorse for many two-way radio users, including railways, public safety and oil companies.
The strength of the early Cadex battery analyzers lies in “Recondition,” a proprietary program that restores nickel-cadmium batteries affected by memory. The Cadex 450 works in conjunction with the original charger and services batteries for GE two-way radios. Only a few units were sold.
