Do hearing aid batteries contain lithium?

Hearing aid batteries 312

Most of the hearing instruments we currently use need batteries to work. Hearing aid batteries are different from standard batteries. They are Zinc-Air batteries and use a different technology.

Many people who use hearing aids are concerned about how many batteries they will waste in their hearing aid.    It is normal to be concerned that you do not have to make an excessive investment in hearing aid batteries.

The life of hearing aid batteries will be affected by the factors we have named above but also by the size of the battery. It is therefore quite difficult to dictate how many batteries a hearing aid will use.

Contact with metallic objects such as keys or coins may cause a short circuit in the hearing aid batteries, therefore, it is recommended not to carry loose batteries in a purse, wallet or purse.

These rapidly rechargeable batteries are environmentally friendly. By using our rechargeable button cell batteries, you will help protect the environment. The rechargeable batteries do not contain heavy metals such as mercury, cadmium or lead. These high performance NiHM batteries are characterized by excellent reliability and quality with no memory effect. All power one batteries are manufactured in Ellwangen (Germany) and undergo strict quality and safety tests.

Hearing aid batteries that have been physically defined as rechargeable (NiMH technology) have a lower energy density compared to zinc-air hearing aid batteries (main batteries). This is expressed by a lower capacity, which is consistent with approximately 1/10 of the capacity of the main batteries. In contrast, rechargeable hearing aid batteries can be recharged approximately 500 times, which means that if a hearing aid is fitted with an ACCU battery, it has a capacity of one day, whereas if the same hearing aid is fitted with a zinc-air battery, it can have a capacity of up to 10 days.

How to recharge hearing aid batteries

How do zinc air batteries work? Unlike common household batteries such as AA, AAA and 9-volt, zinc-air batteries are activated by oxygen in the air. Without oxygen, zinc-air batteries cannot power the hearing instruments.

For optimal performance, open the battery compartments of your hearing instruments whenever you are not wearing them. This limits battery drain and helps alleviate moisture build-up. Turning off your hearing instruments when not in use can also help extend battery life.

Batteries for hearing aids at home

Like any other type of electrical audio device, hearing aids need power to operate. The energy needed to detect and amplify sound is provided by batteries, which are available in two versions: disposable and rechargeable.

Today, rechargeable batteries are used only for BTE hearing aids and those with in-the-canal receivers. Rechargeable batteries are not currently available for custom In-The-Ear hearing systems.

It is a good idea to always have spare batteries on hand in case an in-use battery runs out. You may need to replace a battery if the sound seems unusually distorted or if you have to turn up the hearing instrument volume more than usual. Some hearing instruments beep when the batteries are running low to warn you of the need to replace them.

Disposable batteries are available for behind-the-ear, in-the-ear, in-the-canal and fully in-the-canal hearing aids. Larger hearing instruments generally require larger batteries.
