F.A.Q.

The chemistry of modern hearing aid batteries are not as harmful as those of previous generations, however, If you or your child accidentally ingest a Hearing Aid Battery, it is recommended you consult your doctor immediately.

In 2017, our company achieved an ambitious target to become the world’s first fully ‘mercury-free’ Hearing Aid Battery manufacturer, paving the way to a more eco-friendly future. Since the conversion to mercury-free products, RAYOVAC® has continuously invested in research, development and the manufacturing process, to enable the global switch to the highest quality mercury-free products.

Rayovac currently do not manufacture rechargable hearing aid batteries. Please do not try to recharge any of our products.

Yes, Hearing Aid Batteries are affected by climate, particularly when the weather introduces the Hearing Aid Battery to moisture or dryness. Humid/tropical environments can cause the battery to take on moisture which interferes with the delicate zinc-air chemistry and consequentially reduces battery life. Similarly, dry conditions, such as those associated with very cold environments can cause the hearing aid battery to dry out and prematurely fail.

There are a number of factors which can influence the life of your Hearing Aid Battery. We have created a helpful guide to ensure you get the longest lasting performance from your Hearing Aid Batteries.

It is recommended you store your Hearing Aid Batteries at room temperature, free of moisture. Avoid storing batteries in hot places as this can reduce the life of the batteries. Refrigeration is not recommended as this will introduce moisture to the battery. Hearing Aid Batteries should be kept out of reach by infants or children.

You should not carry around loose batteries in your pocket or purse as interaction with metal objects such as coins or keys can cause the hearing aid batteries to short. When travelling, it is recommended you store your Hearing Aid Batteries in a Rayovac Hearing Aid Battery Caddy, to ensure your batteries are not damaged.

A zinc air technology, such as that used in our Hearing Aid Batteries, uses air from outside of the battery to activate the chemistry within. The factory applied tab seals the air holes in the battery and ensures freshness until you are ready to use the battery. Do not remove the tab until you are ready to use the battery. To activate the battery, you simply remove the tab. After removing the tab, wait about one minute prior to inserting the battery into your hearing aid. This allows sufficient time for the air to enter and activate the ingredients. Replacing the tab when the battery is not in use will not extend the battery life.

Please see the instructions of your brand of Hearing Aid to determine which batteries you should use to power your device.

Most Hearing Aids will come with a specific brand of battery, this does not mean they must specifically use these batteries. Your Hearing Aid will require a certain size of Hearing Aid Battery and can only take that specific size. However, brands are interchangeable.

Rayovac hearing aid batteries undergo over 262 quality checks during the manufacturing process meaning all products are manufactured to the highest possible standard. However, if your customer believes their product quality has been compromised, please contact our customer service team.
