A manufacturer-supplied version or a universal charging station is used for the charging process. Accumulators for hearing aids the size of customary button cells are available. Even for a hearing aid that does not include an integrated accumulator, rechargeable batteries can be an option. Replacing hearing aid batteries does no longer apply. The great advantage of this integrated rechargeable battery system is that batteries will no longer have to be replaced. Just as with other electronic devices powered with batteries, hearing aid users can resort to an accumulator to supply energy to their hearing aids. The alternative to hearing aid batteries: the accumulator With daily use of the device, the batteries have an average service life of five days up to three weeks, depending on wearing time and inherent energy capacities. The various types of hearing aid batteries can be very easily determined according to the standardized color scheme of their protective film: yellow, brown, orange and blue (in order of increasing battery size). In the United States, the most commonly sold type is type 13, primarily used in behind-the-ear devices (BTE).

Some devices can only be operated with type 10 hearing aid batteries, others exclusively with type 675 batteries. Not every battery matches any given hearing aid.

Once the film is removed, even repositioning cannot prevent the normal self-discharge. After removing the film and inserting the batteries into the hearing aid, there can be a delay depending on the particular battery used, until energy supply is ensured. This prevents air from entering through the perforations and reacting with the zinc. In order for this reaction to occur only when the hearing aid batteries are in use, the perforations are factory-sealed with a colorful protective film. The result of this chemical reaction is energy, accounting for the necessary current supply. Zinc-air-systems function according to a simple basic principle: Air penetrates into the casing through perforations on the battery surface and reacts with the contained zinc to produce zinc oxide. Predetermining factors in choosing the right battery for your device are energy requirements and the design of the respective hearing aid. Hereby, the basic rule of thumb applies: The bigger the battery, the more energy it can supply. Hearing aid batteries are mainly offered in four different sizes: 10, 312, 13, and 675. Whereas in the past mercury and zinc batteries were primarily used, today it is zinc-air-systems that are most popular, characterized by a longer service life. As the name might suggest, the small, round, and flat shape resembles a customary button. The usual choice for hearing aid batteries are the button cell batteries, a type of micro batteries.
