About Master Battery

Master Battery is a trusted, locally operated battery distributor serving Knoxville and Nashville, Tennessee. For decades, we have supported automotive, commercial, industrial, and retail customers with dependable products, knowledgeable service, and practical solutions.

Today, Master Battery operates as part of Stored Energy Holdings Inc. (SEHI), a growing national network of battery distribution companies that includes Northeast Battery, Tri-State Battery, and Battery Men. While each company maintains its strong local identity and customer relationships, together we benefit from shared resources, expanded product access, and coordinated logistics across multiple regions.

This structure allows Master Battery to combine the responsiveness of a local business with the purchasing power and operational scale of a larger organization—ensuring competitive pricing, reliable inventory, and consistent service.
