Hearing aid batteries are an essential hearing aid supply. With the exception of rechargeable or disposable hearing aids, all hearing aids need an ongoing supply of hearing aids. Different types of hearing aids require different size batteries. The type of hearing aids and the amount of hearing aid usage affects how often that the hearing aid batteries need to be replaced.

Hearing aid batteries are typically sold in packs of four or six batteries or cartons of forty or sixty batteries. Some cartons of sixty batteries range in price from thirty to forty-five dollars. Prices vary depending on the type of battery, size, manufacturer, and where they are sold.

A hearing aid dryer dries the moisture that can interfere with the proper functioning of the hearing aid. Wearing hearing aids can cause moisture to accumulate in the hearing aid. This problem can be worse for some hearing aid users than others. A hearing aid user who is very active or sweats more than usual may need to use a hearing aid dryer regularly.

Hearing aid dryers can be electric or in the form of a jar with drying chemicals. An ear mold air blower is a bulb syringe used to dry moisture and blow debris from the hearing aid. Hearing aid brushes are small brushes used to clean dirt and debris from the hearing aid.

Some hearing aid supplies are designed to prevent the buildup of moisture in the hearing aid. One product is a set of replaceable latex covers for the hearing aid. The latex covers fit over the hearing aid while allowing a clear space to avoid obstructing the microphone. Latex covers should not be used by hearing aid users who are allergic to latex.

The hearing aid supplies help ensure that the hearing aid is able to function at its optimum level. Cleaning the hearing aid and removing moisture may help prevent hearing aid malfunctioning. Hearing aid supplies can be found on the Internet, at hearing aid suppliers, through audiologists, and at some stores.

When the tab on the back of the battery is pulled, the battery is activated. The battery works when the zinc inside the battery combines with air. The tab is meant to keep the battery inactive until the user is ready to use the battery and pulls the tab which allows air to mix with the zinc inside the battery.

Heat can loosen the adhesive that holds the tab on the battery. If the tab becomes loose, the battery may be activated before the user is ready to use the battery. This decreases the life of the battery. Therefore, hearing aid batteries should never be stored in cars, near a heat source, or other areas that may become hot.

Hearing aid batteries should be stored at room temperature. Batteries can be stored for three or four years before they start losing power. They should not be stored outside of a package among other metal objects as contact with metal can cause the battery to leak or rupture.

Once the tab on a hearing aid battery has become loose or has been pulled, the battery cannot be deactivated by replacing the tab. Once the battery is activated, it remains active until it wears out. The typical life of a hearing aid battery is five to seven days, but this can vary with different types of hearing aids and the frequency of use of the hearing aid. Digital hearing aids usually require more frequent battery changes than analog hearing aids. When purchasing a hearing aid, the customer may want to ask the medical professional how often the battery will need to be replaced.
