MK Battery was founded by Mark Kettler and Mark Wels in January 1983 and incorporated in August 1984, as a California "C"- type corporation. The company has over 100 employees including Mark Wels who continues to manage the company as President. MK Battery was acquired by East Penn Mfg. Co. Inc., Lyon Station, PA, in September 1995, and operates as a wholly-owned subsidiary of East Penn. In January 2002 MK Battery opened its first direct sales and distribution branch in Europe, located in Kettering, Northamptonshire, England. A second European branch opened in March 2005 in Arnhem, The Netherlands and, in 2009, the company opened offices and distribution in Sydney, Australia to service the Asia Pacific region.

Headquartered in Anaheim, CA, MK Battery now operates 20 distribution centers in the USA, five in Europe, and one in Australia, out of which we deploy a fleet of route delivery trucks. Each distribution center is staffed by MK Battery personnel. Additionally, East Penn Mfg. Co. (DEKA) provides warehouse services to MK Battery in numerous other USA locations. East Penn Canada, East Penn owned, markets MK Battery's brand names in Canada and supports MK Battery with inventory in multiple locations throughout Canada. Consequently, MK Battery has one of the most extensive distribution systems for sealed batteries in all of North America and throughout much of the world.  As such, MK Battery brands are sold and distributed on all seven continents.
