A Reliable Supplier

Fedco Electronics, Inc. is a closely held corporation that was established in 1975 for the purpose of offering quality off-the-shelf electronic components. In the early 1980's the company began distributing quality replacement battery products to public utilities as well as the emerging computer market with the same off-the-shelf discipline. Today, although we continue to offer replacement batteries and AC adapters for the computer market at, we have developed a highly efficient facility capable of offering custom battery assemblies for low to medium volume requirements.

All of our custom battery packs are designed and manufactured in our Fond du Lac, Wisconsin facility under our ISO 9001:2008 certified Quality Management System, and managed by an experienced management team, including a staff of four graduate engineers. The custom molded plastic battery housings as well as custom Protection Circuit Modules and SM Bus battery status circuits used in our lithium-ion battery assemblies are manufactured by ISO certified companies located within Wisconsin. The end result is a truly "Made in the U.S.A" product line.

Our off-the-shelf discipline as well as a large inventory of standard battery assemblies enables us to offer quick turnaround time of functional prototypes. Often times only a change in connector design or similar revisions can produce a final product. When you call us at 1-800-542-9761 you will immediately be speaking to one of our experienced customer service staff who will be able to listen to and understand your needs.
