HEARING AID BATTERY HISTORY
RAYOVAC®, the #1 manufacturer of hearing aid batteries, has a long and proud history of innovations, which among others, includes the introduction of zinc air cells, new hearing aid battery references, pack sizes and innovative packaging designs.
However our relationship with the hearing industry stretches back much further with our first involvement nearly 80 years ago with the first wearable vacuum tube hearing aid in 1937.
Since then we have worked tirelessly with the industry to ensure that our products are developed to meet the changing needs of the consumer.
Our first production facility was opened in the USA in 1963 with a second hearing aid battery production facility opening in the UK in 1989 to serve the European market.
In addition to consistent hearing aid battery quality, RAYOVAC® supports its exceptional products with world-class programs, promotions and collateral materials.
In the future – as in the past and present – RAYOVAC® is committed to retaining its undisputed leadership position by continuing to provide the technology enhancements, packaging and shelf-life improvements and innovative programs that make RAYOVAC® the #1 Manufacturer of Hearing Aid Batteries.
