Welcome 
Customers
If you're looking for unipower.com, then you're in the right place. Welcome to OSI Batteries, the new home of Unipower brand products.
You may have been automatically redirected here, as OSI Batteries completed the migration and shutdown of the old Unipower website on 10/14/22. Along with that migration, we have moved all customer account information, skilled manufacturing staff, production capabilities and standards, and process quality expertise to our newly renovated OSI headquarters. You can rest assured that your customer experience will continue to be the primary focus of our Unipower medical division. Additionally, we deliver professional battery solutions for all the operational needs of your business. Contact us with any questions you may have about this transition, or to learn more about how OSI can help you power your day.
