best hearing aid batteries
Hearing aids, especially modern hearing aids, are vital for the hearing impaired. However, they cannot function properly without being powered by batteries. There are many different types of hearing aid batteries, each with its own specific usage scenarios, advantages, and disadvantages. Therefore, the correct selection of hearing aid batteries is essential to ensure the stable operation of hearing aids and extend their service life.


 一、 Types of hearing aid batteries

Hearing aid batteries are mainly categorized into the following types according to their different sizes, capacities, and uses:

  1. Zinc-air battery: This is the most commonly used type of battery for hearing aids; the principle is to utilize the oxygen in the air and the zinc powder inside the battery to generate electricity by chemical reaction. The advantages of zinc-air batteries are their high capacity, stable voltage, and long service life, and they are suitable for most hearing aids. Depending on the size, zinc-air batteries can be categorized into A10, A13, A312 and A675 models.
  2. Silver-zinc batteries: Silver-zinc batteries have high energy density and good stability, but their price is relatively high. They are generally used in high-end hearing aids or special-needs hearing aids.
  3. Lithium batteries: Lithium batteries have higher energy density and longer service life. Still, they are more expensive and require special charging equipment, so they are not commonly used in hearing aids.

二、How long does the battery usually last?

The battery life varies greatly depending on the hearing aid model, power, degree of hearing loss, living environment, and other factors. Generally speaking, the more features and advanced the hearing aid, the higher the demand for power and the faster the consumption.

Secondly, the more severe the hearing loss or the higher the need for amplification, the faster the battery consumption. The climate also affects the consumption rate so that the battery will run out faster in winter.

三、How to choose the correct hearing aid battery

Choosing the correct hearing aid battery requires consideration of several factors, including the hearing aid model, frequency of use, battery life, and personal budget. Here are some specific selection strategies:

  1. Know your hearing aid's battery model: Different hearing aid brands and models often use different-sized batteries. Therefore, before choosing a battery, check the manual of your hearing aid or consult a professional to determine the model and specifications of the battery you need. Avoid purchasing the wrong type of battery, which may damage your hearing aid or affect its effectiveness.
  2. Consider frequency of use and duration: Frequency and duration are vital when choosing hearing aid batteries. If you need to use your hearing aid for an extended period every day, selecting a battery with a large capacity and a long battery life is more appropriate. On the other hand, if you only use your hearing aid occasionally, you can choose a battery with moderate capacity and a relatively low price.
  3. Pay attention to the quality and brand of the battery: The quality and brand are directly related to the hearing aid's operational stability and service life. High-quality batteries have better performance, longer service life, and higher safety. Therefore, when choosing batteries, you can select products from well-known brands to avoid the risks of purchasing poor-quality batteries. At the same time, you can also pay attention to the reviews and recommendations of other users to understand the actual use of the battery.
  4. Consider personal budget: The price of hearing aid batteries varies depending on brand, model, and capacity. When choosing a battery, we need to weigh it against our budget. Although price does not necessarily mean quality, too cheap batteries may have safety hazards or unstable performance. Therefore, we can choose cost-effective battery products that fit our financial situation and needs.

四、Use and Maintenance of Hearing Aid Batteries

In addition to choosing the correct battery, proper use and maintenance are crucial to ensuring the performance of your hearing aid batteries. Here are some suggestions:

  1. Install the battery correctly: When installing the battery, pay attention to the direction of placement of the positive and negative terminals to avoid short-circuiting or damaging the hearing aid. At the same time, make sure that the battery is in good contact with the hearing aid battery compartment to avoid affecting its normal use.
  2. Replace the batteries regularly: Replace the batteries regularly according to the frequency of use and battery life of the hearing aid. Avoid battery depletion, which can cause the hearing aid to stop working suddenly and affect the hearing experience.
  3. Store batteries in a dry, cool place, avoiding direct sunlight and high temperatures. High temperatures may accelerate the chemical reactions inside the battery, shortening its life. It is also important to avoid placing batteries with metal objects to prevent short-circuiting.
  4. Avoid mixing old and new batteries: Mixing old and new batteries may result in unstable battery performance, affecting the hearing aid's use. Therefore, when replacing batteries, ensure all batteries are new and try to use batteries of the same brand and model.

五、Battery or rechargeable hearing aids?

01. Battery hearing aids


  1. There is more room for choice, as there are different models and price levels suitable for users with different economic conditions and needs. 2.
  2. There is no limitation of power supply, no aging of batteries, and small batteries can be replaced at any time. As long as you carry a spare battery with you, you can ensure battery life, and you can listen as long as you want.


  1. The battery needs to be replaced manually. If the user has limited hand dexterity, blurred vision, or other conditions, it is not recommended to choose the battery model.
  2. Depending on the hearing loss, the use of the environment, the performance of the hearing aid, and other factors, the battery model of the hearing aid batteries can generally be used for 5-15 days. Then, the batteries need to be bought for replacement.

02. Rechargeable Hearing Aids


  1. Simple operation: You only need to put the hearing aid into the charging box every night before going to bed to charge it; the operation is effortless.
  2. There is no need to buy or replace the battery; just charge it directly like a cell phone, which is easy to operate. And now, some hearing aid charging boxes, such as the Chosgo hearing aid charging box, set charging, drying, storage of electricity, and other functions, not only do not need to buy batteries but the drying box is even saved.
  3. To reduce the occurrence of malfunctions, the rechargeable hearing aids' moisture-proof and dust-proof performance does not require opening and closing the battery compartment door; the shell is completely sealed, which helps to protect the hearing aid from moisture, sweat, and dust damage.


  1. Although rechargeable hearing aids are easy to charge, they take time and cannot be worn. If there is a charging problem, it is usually impossible to deal with on your own, and you must return it to the factory for repair.
  2. Not all hearing aids are available in rechargeable models, and rechargeable hearing aids are generally slightly more expensive than battery-operated hearing aids.

Choosing the correct hearing aid battery is essential to ensure the proper functioning of the hearing aid and to prolong its service life. When selecting a battery, we need to know the battery type of the hearing aid, consider the frequency and duration of use, pay attention to the quality and brand of the battery, and consider our budget. At the same time, proper use and maintenance are vital to ensure the battery's performance. By considering these factors, we can choose a hearing aid battery that suits our needs and brings a better hearing experience to people who are deaf or hard of hearing.

If you have a low budget and are only considering a basic hearing aid, it is recommended that you choose a battery-operated Chosgo V03B Mobile APP Control Bluetooth Hearing Aid.

If you are considering a mid-range or high-end Chosgo hearing aid, you can choose according to your needs. The battery model can be used with the battery installed; the rechargeable model can be recharged by placing it in the battery compartment, which saves you the trouble of changing batteries compared to the battery model, and you don't have to buy batteries later, which is also a trend in the future.
