Headquartered in Minnesota


Paul Ohlin founded Ohlin Sales Inc in the early 1970s as an independent manufacturers sales representative for battery industry pioneers including Eagle-Picher and Alexander Batteries.

  • EaglePicher Technologies’ history as a battery manufacturer dates back to 1922 when they developed a line of efficient lead acid batteries. The company’s longtime heritage as an industry leader in battery production has resulted in the diverse line of products that exists today. EaglePicher batteries have powered everything from Navy torpedoes to the Mars rover.
  • Alexander Batteries was founded in 1967 and quickly became a leading manufacturer of portable two-way radio batteries. In 1982 the company was awarded a contract to make batteries for U.S. Marine Corps and by 1995 the company manufactured 1,800 types of battery units including medical batteries and barcode scanner batteries.

Paul’s charm and humour helped form lasting business relationships with clients and vendors that continue to the present. Paul operated with the simple but effective business philosophy of offering quality products and treating people the right way – our core goal is to continue this tradition.

Paul’s son Tom joined the company in the early 1990s and helped transition it from manufacturers representative to our current model as a top distributor for industry leading brands and doing business as OSI Batteries. Battery Network was acquired in the early 2000s giving the company a presence on the west coast and helping support a growing nationwide customer base. The acquisition also led to some key supply chain partnerships both domestically and abroad that allowed us to introduce our own line of private label aftermarket batteries for portable two-way radios, barcode scanners, and more.

OSI Batteries has been an authorized distributor and value add center for EnerSys products since the early 2000s. EnerSys is the largest industrial battery manufacturer in the world and their reserve power batteries are marketed and sold principally under the PowerSafe, DataSafe, Hawker, Genesis, ODYSSEY and CYCLON brands. EnerSys battery products span a broad range of sizes, configurations and electrical capabilities, enabling us to meet a wide variety of customer applications.
