NHS Hearing Aid Batteries Options

NHS hearing aids and batteries present an alternative resource to assist the hard of hearing.

In this blog post, we highlight which batteries we supply to support an NHS hearing aid.

NHS Hearing Aid Batteries

Obtaining a hearing aid from the NHS is free of charge on a loan basis. In addition, the NHS provides you with a selection of free batteries as well.

Hearing aid care is essential for its longevity and proper functioning. Using and storing the appropriate type of hearing aid batteries is an important part of ensuring that your hearing aids will perform to its best capability.

At Hearing Direct, you will find a wide choice of hearing aid batteries from a number of leading brands and manufacturers that are NHS hearing aid compatible.

What Batteries Do I Get With My Hearing Aid?

When it comes down to hearing aid batteries, it's a case of identifying which batteries suit you and your device. As long as you insert the correct sized battery, your NHS hearing aid will be fully powered.

There are several brands offered by the NHS including:

The above battery brands will complement NHS Hearing Aids and other hearing aid manufacturers. However, all other zinc air brands on the market are suitable. All of which can be ordered online directly from hearingdirect.com.

Choosing Hearing Aid Batteries

There are various brands and sizes of hearing aid batteries, so before purchasing, it is important to know which battery type best fits your hearing device. Choosing a brand is mostly personal taste and preference and you may have to experiment with various brands to find which ones you prefer.

We have trial packs of batteries available which let you test different brands before settling on the right one.

What Size Batteries Do I Require?

We supply all the most popular hearing aid battery sizes. All hearing aid batteries come in 4 sizes with numerical values. To determine the exact size you need, you have to look at your hearing aid manual or consult your audiologist.

To make size choice easier, the batteries also have corresponding colours that are unified across all manufacturers.

  • 10 = Yellow
  • 13 = Orange
  • 312 = Brown
  • 675 = Blue

You can get the batteries you need for your hearing aid completely free if you carry your NHS brown record book with you when you pick them up. There are a number of places across the UK where NHS batteries are available, e.g. hospitals or GP surgeries. In addition, you can also turn to Deaf Access as they also provide the service. Solihull NHS Care Trust can even send you the batteries by post as an alternative to the regular collection in person.

Hearing Aid Battery Care

The batteries usually come in packs of six so you will have spare batteries after you open the package.

Make sure each battery has a protective seal on it before you change the battery. In cases where the seal is compromised, it is highly likely that the battery will not perform well. All hearing aid batteries are zinc air, which means they become active when they first make contact with air and this process is not reversible and commences as soon as the seal on the bottom is removed.

The average life of a battery varies depending on the amplification you use and how many hours per day you wear your hearing aid. The battery life could be anywhere between a week and a few months, assuming you use fresh batteries and store them and the device properly. To keep your batteries safe, it is best not to mix them with old ones, avoid putting them near metal objects (e.g. keys), ensure the seal stays in place until you need to use them or store them in a battery caddy.

To avoid contaminating the environment with dangerous chemicals, after using the batteries it is best to return them for recycling rather than simply throw them away. To assist in protecting the natural world, many manufacturers such as Rayovac have now stopped using mercury in the battery composition and provide eco-friendly batteries.
