Our history

1972


Paul Ohlin Sales, Inc

Paul Ohlin founded Paul Ohlin Sales, Inc. in 1972 and worked as an independent manufacturers sales representative for battery industry pioneers, including Eagle-Picher and Alexander Batteries. His natural charm and humor helped form lasting business relationships with clients and vendors that still continue to this day. Paul operated with the simple, but effective business philosophy of offering quality products and treating people right. This approach remains our core goal.

1991


Ohlin Sales, Inc

In the early 1990s, we incorporated as Ohlin Sales, Inc., and Paul’s son, Tom, joined the company. Tom helped to transition us from manufacturers representative to a top distributor for industry leading brands. As our battery applications and offerings expanded, we began doing business as OSI Batteries.

2000

Acquired Battery Network

We acquired Battery Network in 2000, which gave the company a presence on the West coast and also helped support our 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.

A new look for OSI

2020 brought a lot of changes to OSI. We launched a brand-new website and went through a rebranding process to refresh our logo to a more modern look.
