Rayovac’s Portage Plant Celebrates its 50th Anniversary

Middleton, WI - August 1, 2014

Today, Rayovac’s Portage plant is celebrating 50 years of operation. To commemorate half a century of community involvement in the city of Portage, Rayovac is proud to announce this unique milestone.

Rayovac, a division of Spectrum Brands, Inc. (a subsidiary of Spectrum Brands Holdings, Inc.) Holdings headquartered in Middleton, WI, holds the rank of global market leader while producing the number one selling hearing aid battery in the world. Rayovac’s proprietary formulation and manufacturing process were crucial to achieving these lofty milestones. All Rayovac hearing aid batteries are produced in Portage or at a companion facility in the United Kingdom. Each year, the facility manufactures hundreds of millions of hearing aid batteries, its primary focus, while also producing a large quantity of lithium batteries.

Over the course of 50 years, the Portage facility has experienced a number of significant milestones. The Portage plant was constructed in 1963, with production commencing in 1964. From that point, the Rayovac Portage manufacturing facility has continually grown in both size and scope of production. By 1977, production demands had grown beyond manufacturing capacity, so Rayovac moved into its current facility on Portage Road. In 1982, the facility began producing zinc air batteries.

"The Portage plant has been successful for the past half a century because of the adaptability of the workforce as well as continual investment in product development and new technology," said Dave Young, Portage Plant Manager. "The plant’s steady growth through the years is a testament to the commitment and effort of everyone working at this facility."

Rayovac has been at the forefront for its industry leadership in technology, performance, reliability and sustainability. A proud member of the United Nations Environment Programme (UNEP) Global Mercury Partnership, Rayovac is committed to removing mercury from hearing aid batteries and urging the ban on usage of those with mercury in the U.S. At the 2012 In Business Sustainability Awards Program, the plant won the prestigious Eco-Product of the Year Award for eliminating mercury from its hearing aid batteries and the Eco-Efficiency Initiative of the Year Award in recognition of its effort to improve the plant’s practices and achieving a reduction in its carbon footprint.
