About GNB Systems

About Great Northern Battery Systems

Canada's Largest In Stock Selection of Batteries

With a long strong history in Ontario, Great Northern Battery Systems was born in 1936 as Heart Battery. Providing a wide range of batteries for automotive, commercial, marine and industrial applications Heart Battery grew until in 1958 it was purchased by Harold Fisher and renamed Acme Battery.

Acme Battery continued where Heart Battery left off by providing a wide selection of batteries and related products. By providing top quality products, knowledgeable advice and highly competitive pricing Acme continued to grow and expand becoming a wholesale supplier to many OEM’s, as well as establishing a country wide dealer network.

In 1996 and still owned by Harold Fisher, Acme Battery changed its name to Great Northern Battery Systems. Joined by his children Allessa and Erroll, the Fisher family has continued to grow GNB Systems into one of North America’s largest battery wholesale distributors on a per capita basis.

In 2017 GNB Systems grew again with the addition our Toronto location. Managed by Lowell Fisher, Harold’s youngest son, the Toronto showroom and sales centre is strategically located on Highway 27 in Woodbridge.

Today with 2 locations, Hamilton and Toronto, Ontario, GNB Systems continues to provide a full range of batteries, battery accessories, chargers and more.
