Innovative developments and the highest manufacturing standards ensure the outstanding quality of our product range. This quality is demonstrated time and again with valued customer feedback, the awards we win and the simple fact that the number 1 selling hearing aid batteries worldwide are Rayovac batteries*. Alongside our research and development work, this result is primarily due to our employee expertise and stringent quality control.
We have developed an advanced test regime that accurately reflects device and consumer requirements. ”Following the most recent guidelines established by ANSI and IEC, battery performance, quality and reliability are strictly monitored assuring the very best performance battery after battery.”
Our European manufacturing facility in Washington produces hearing aid batteries to the highest certifications, along with using Statistical Process Controls to ensure consistency of product. To maintain our market leading position, we use internationally qualified professionals to launch new products as well as improve on our existing lines. Over a century of continual, innovative development is kept up to date thanks to constant research and further developments.
To demonstrate our leadership in hearing aid battery performance, our engineers perform a series of quality tests to ensure customers receive a consistent battery every time. Over 300 in-process tests are performed on incoming materials, the latest in laser and camera measurement is used to assess and inspect and 69 finished cell tests are performed on each cell lot.
We push our batteries to the limit, testing at extremes of temperature and humidity before every single battery is electrically tested for OCV and impedance prior to shipment. Combined, these tests ensure our customers receive batteries that are reliable, and allow them to simply live their life, uninterrupted.
We are so confident that your patients will be satisfied with our hearing aid batteries that we guarantee them. If customers are unsatisfied with the life or performance of Rayovac batteries we will refund their money, and we will repair or replace any hearing aid damaged by our batteries. Battery and hearing aid should be forwarded to Rayovac. ***Guarantee is void if the battery shows signs of recharge.
