Dyno Battery

Dyno Battery

The year was 1947, shortly after the end of World War II, Charles E. Knowlton Sr., a Seattle resident since 1928, and his son, Mark A. Knowlton, pooled their resources and purchased a modest eight-man "plant" the Dyno Battery Company, which manufactured car batteries. Building on Dyno's already established reputation for producing a quality product, Charles and Mark embarked on a program to increase volume and product line.
