Hearing Aid Batteries Size 10a - The Different Types of Hearing Aid Batteries

When a person reaches a certain age, their hearing will lessen until it becomes no more. Aside from that, even children can have congenital disabilities that cause them to have a hearing impairment. Luckily, it can easily be turned around by having a hearing aid.

A hearing aid is a device that's precisely what it sounds like: it allows a deaf person to hear. However, being a gadget, it can be pretty hard to maintain since some parts, such as the battery, are hard to come by. Conversely, one who cares for a deaf person should also acquaint themselves with the basics of a hearing aid battery to help their loved one improve their quality of life.

For this reason, we'll discuss the basics of hearing aid batteries in this article. Read on below to get started.

Types of Hearing Aid Batteries

First and foremost, there are two primary types of hearing aid batteries. These are:

Standard Disposable Batteries

Standard disposable batteries are the most common hearing aid batteries, especially zinc-air ones. As the name suggests, this hearing aid battery should be disposed of immediately after its lifespan ends.

One of the advantages of disposable batteries is that they're affordable, but there's a catch: they don't come with an expiration date. So, if you're planning to purchase them, it would be best to buy them from a reputable seller, especially if they're not cheap. You should also compensate for its shortcomings by keeping it in a cool, dry place. It would also be wise to keep your eye on it since standard disposable batteries usually lose their charge after a few days.

Rechargeable Hearing Aid Batteries

Like any other electronic device that uses batteries, even hearing aids have a rechargeable variant. Rechargeable hearing aid batteries are more expensive, but they're worth it in the long run. They're much more economical than the disposable ones since they can be recharged and reused.

Aside from that, it's practical since you don't have to spend as much on batteries as you would if you get disposable ones. Still, never buy them without checking their authenticity and quality, as that would be a waste of money.

Hearing Aid Battery Sizes

Hearing aid batteries also come in different sizes, meaning you can't just look at a hearing aid battery and know that it will work for your hearing aid. These sizes are as follows:

Size 5

Size 5 is the smallest of hearing aid batteries, and it comes in a size of 9.6 mm x 4.3 mm x 5.3 mm while powered at 1.45 V. It's also the most common battery size since it's used in pretty much every hearing aid in the market.

Size 10a

The size 10 is bigger than the Size 5 by a significant amount. It's 5.8 mm wide by 3.6 mm high. The Size 10 is the second most common battery since it's mainly used in heavy-duty hearing aids.

Size 312

The size 312 battery is one of the more popular choices for cheaper hearing aids. Its size is 7.9 mm wide by 3.6 mm high.

Size 13

The size 13 is the second-biggest hearing aid battery. It's used in hearing aids requiring great power to function efficiently, such as digital technology. Its size is 7.9 mm wide by 5.4 mm high.

Size 675 Hearing Aid Battery

The size 675 is the biggest hearing aid battery at 11.6 mm wide by 5.4 mm high. It's primarily used in hearing aids with the highest power required.

What Should You Get?

In the end, whether you'll buy disposable or rechargeable hearing aid batteries will depend on you. It would be best to go with the more practical one for your situation, such as getting rechargeable batteries if you'll be too busy to dispose of the used ones. On the other hand, if you might not use the hearing aid that often, getting disposable ones would be better.

The same goes for the battery size. It all depends on the specs of the hearing aid, so be sure to look at the instruction manual to ensure that you'll buy the correct size.


The purpose of a hearing aid is to stimulate one's hearing, and for that, it needs a lot of power. For this reason, it's crucial to understand the basics of hearing aid batteries since they're the source of that power. Just be sure to shop around and know what you need so that your hearing aid will work properly.
