Globe-Union was a Wisconsin based manufacture of Automotive batteries for both the replacement and OEM markets. Today, Johnson Controls is the largest producer of private label lead acid batteries in North America, and is becoming a leader in Asia and South America. In 2000 Johnson Controls acquired Gylling Optima Batteries AB of Sweden. The Optima Gel Battery is well known for its quality and longevity. Johnson Controls completed the acquisition of German automotive battery maker HOPPECKE Automotive GmbH & Co. The company has a excellent customer base that includes many of Europe’s leading auto manufacturers. Johnson Controls also produce batteries for other applications such as marine, lawn and garden, commercial, motorcycle, wheelchair, and golf cart use. Most consumers have no idea of the size of the battery giant. When people think of Johnson Controls, they think of thermostats for HVAC purposes not batteries. Johnson Controls is not only the largest North American battery manufacture, but they literally control the North American battery market.
Johnson Controls manufactures batteries for the following private labels:
