Which Hearing Aid has the Longest Battery Life?

When it comes to hearing aid batteries, the battery life can vary depending on the type of hearing aid, the battery brand, and the size of the battery. However, some hearing aids have longer battery life than others.

According to the Hearing Aid Battery Club, the hearing aids with the longest battery life are typically those that use size 13 batteries. These batteries can last up to 240 hours, or about 10 days, depending on the hearing aid and usage.

However, keep in mind that battery life can vary depending on how often you use your hearing aid and the features you have enabled.

Do Some Hearing Aid Batteries Last Longer than Others?

Yes, some hearing aid batteries last longer than others. Battery life can vary based on the brand and type of battery, as well as the size of the battery.

In general, zinc-air batteries tend to last longer than other types of batteries. These batteries use oxygen from the air to activate the battery, which can provide longer battery life. However, keep in mind that zinc-air batteries can’t be recharged and can lose power even when not in use.

It’s also important to note that battery life can vary between batteries of the same brand and size. This is because the production process can affect the battery’s performance.

Is There Any Difference in Hearing Aid Batteries?

While all hearing aid batteries serve the same purpose, there are some differences between them.

The main difference is the size of the battery. Hearing aid batteries come in different sizes, with the most common sizes being 10, 13, 312, and 675. The size of the battery you need depends on the size of your hearing aid.

Additionally, different brands of batteries can have different performance characteristics. Some batteries may last longer or perform better in high-drain situations.

What is the Most Common Hearing Aid Battery Size?

As mentioned earlier, the most common hearing aid battery sizes are 10, 13, 312, and 675. The size you need depends on the size of your hearing aid.

In general, smaller hearing aids, such as in-the-canal or completely-in-the-canal models, use smaller batteries (size 10 or 312), while larger hearing aids, such as behind-the-ear models, use larger batteries (size 13 or 675).

When shopping for hearing aid batteries, be sure to check the size requirements for your specific hearing aid. Using the wrong size battery can damage your hearing aid or result in poor battery life.


When it comes to hearing aid batteries, there are many factors to consider, including battery life, brand, type, and size. By understanding your hearing aid’s requirements and comparing different battery options, you can find the best battery for your needs and ensure reliable performance from your hearing aids.
