Renata Zinc-air Hearing Aid Batteries are engineered to power both analog and digital hearing assisted devices. Their high constant voltage assures long battery life.

Packaged in easy-to-use dial cards, we stock all popular sizes—10, 13, 312 and 675. Renata hearing aid batteries are precision-made in Switzerland and Germany.

Trust you hearing to Swiss-quality power

Founded in Switzerland in 1952, Renata is a producer of micro-batteries for electronic applications, specializing in zinc-air batteries for hearing devices, silver-oxide batteries for watches, and 3V lithium coin cells.

Renata is experienced with the end-to-end battery production process—from development and inspection of raw materials to the testing of the final product. Research, development, production and quality testing are grouped at its modern, highly automated, production plant headquarters in Itingen.

Renata is ISO 9001 and ISO 14001 certified by Bureau Veritas (Switzerland, updated December 2020).
  • 100% mercury-free.
  • Long battery life due to optimally high constant voltage.
  • Optimized for wireless communication.
  • Ideal for analog, digital, and ultra high power hearing aids.
  • Developed in Switzerland and quality manufactured in Germany.

Why is zinc-air technology used in hearing aids?

The battery capacity is greater than any other battery with the same design. In addition, zinc-air batteries are especially suitable for high currents; therefore they meet the needs of hearing aids perfectly.

Can I use my Renata zinc-air battery in both analog and digital hearing aids ?

Yes you can. Engineers have developed our zinc-air batteries over a period of many years so that the latest generation of Renata batteries is ideally suited to both technologies.

How should I store my zinc-air battery?

Ideally a zinc-air battery should be stored at room temperature in the original package. Storage in a very dry orhumid climate (e.g. exposed to direct sunlight) or in a cold place (e.g. in a refrigerator) may significantly shorten the battery service life. Batteries should not be allowed to come into contact with metal pieces (such as coins or keys), as this may create a shortcircuit.

What points should I bear in mind when my zinc-air battery is fitted in the hearing aid?

Oxygen from the surrounding air reacts with the zinc to supply the required current. In its original pack, the battery is sealed with adhesive tab which protects it against environmental influences. In this condition, very little oxygen is present in the battery. Its voltage is therefore reduced. After removal of the tab, oxygen enters the battery and the voltage rises to more than 1.4V (open circuit voltage). Wait for 1 to 2 minutes after removal of the adhesive tab before placing the battery in the hearing aid.

What is the voltage of my battery?

An activated zinc-air battery which is not under load has a voltage of more than 1.4V, the operating voltage is slightly lower than this. If the voltage falls below 1.1V in a digital hearing aid, an alarm sounds or the device switches itself off.

Do more air holes mean a longer battery life and greater power?

No. The quality and design of the air electrode are the decisive factors.

How long will my battery last?

In principle, Renata batteries are typified by a broad spectrum of use and a long service life. However, the service life of a zinc-air battery depends on different factors such as the type of hearing aid, the chosen amplification, the surrounding noise level and climatic conditions such as temperature or atmospheric humidity.

Are battery testers suitable for zinc-air batteries?

In zinc-air batteries, the voltage remains constant through the period of use and the state of discharge therefore cannot be determined by measuring the voltage. Conventional battery testers are not suitable.

For your health and safety, this item can not be returned or exchanged after opening. Thank you for your understanding. Order carefully, 20% restocking fee for unopened returns.

As with any "zinc-air" hearing aid battery that is "air activated", it is highly recommended that you wait at least 60 seconds after you remove the Protective Tab before turning on your hearing aid. This will activate the battery and you will get the most out of it.
