What do you need to know about hearing aid batteries?

Date:May 10, 2019

In terms of hearing aids, batteries are one of the most important things. Hearing aids require a high-quality hearing aid battery to obtain a stable power supply for proper and correct operation. Low battery or defective batteries can seriously affect the performance of hearing aids.


There are five things you should know about hearing aid batteries:

Longest battery life

Standard hearing aid batteries last for 3 to 22 days, depending on the type of hearing aid, battery type and capacity, and the frequency with which the hearing aid is used.

Replacement battery

Depending on how often you use your hearing aid, you may need to replace the battery once a week or replace it twice a month. You should replace the battery if any of the following conditions occur:

• The sound becomes distorted, or you must increase the volume of the hearing aid than normal.

• The “Low Battery” beep or voice sounds, indicating that the battery is low and should be replaced. Switch to a new set of batteries as soon as you hear this sound.

Note: The batteries should be removed immediately to prevent them from expanding and difficult to remove afterwards.

Protective seal

You may have noticed that each battery in the package has a small sticky label in orange or other colors. These protective seals prevent the battery from discharging, so do not remove the seal unless you are using the battery. Also, never buy an open battery pack because the battery is extremely likely to be damaged.

Let the battery breathe

It is recommended to leave the battery for about 1 minute before inserting the hearing aid. Please note that this helps to charge the battery, but may not directly extend battery life.

How to minimize battery drain

Once you remove the protective seal from the battery, it begins to discharge. However, there are three things that can help minimize battery drain.

1. When not wearing the hearing aid, turn it off or open the battery cover. Please note that you should always open the battery door at night to prevent moisture from escaping and help protect the battery from corrosion.

2. If you do not use the hearing aid for a long time, remove the battery completely. You can store it in the protective case of the hearing aid.

3. Avoid storing batteries and hearing aids in extreme temperatures, heat and cold, as they can quickly drain the battery and shorten the life of the battery.


• Tip 1: The battery may suddenly lose power, so be sure to carry an additional device with you. Keep extra packages on your wallet, car, briefcase or desk.

• Tip 2: Keep the spare battery away from coins, keys and other metal objects to avoid accidental discharge before use.

• Tip 3: Store the battery at normal room temperature, do not refrigerate or expose to extremely hot or cold temperatures.

• Tip 4: Wash your hands before replacing the battery. Grease and dust residue on the battery can damage the hearing aid.
