NHS Hearing Aid Batteries Options

Taking care of your hearing aid is essential for its longevity and proper functioning. Using and storing the appropriate type of batteries is an important part in ensuring that your hearing aid will perform to its best capacity. There are different brands and sizes of hearing aid batteries, so before purchasing it is important to know which battery type corresponds to your hearing device. Choosing a brand is mostly personal taste and preference. You may have to try various brands to see which ones you prefer.

Obtaining a hearing aid from the NHS is free of charge on a loan term basis. In addition, the NHS provides you with free batteries as well. There are several brands offered by NHS including Rayovac, Power One, ZeniPower and Duracell. However, all other Zinc Air brands on the market are acceptable. All hearing aid batteries come in 4 sizes. To determine the exact size you need, you have to look at your hearing aid manual or consult with your audiologist. To make size choice easier, the batteries also have corresponding colours that are unified across all manufacturers. These are yellow tab size 10, orange tab size 13, brown tab size 312 and blue tab size 675.

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 too provide the service. Solihull NHS Care Trust can even send you the batteries by post as an alternative to the regular collection in person.

Storage and care for batteries

The batteries usually come in packs of six so you will have spare batteries after you open the package. Make sure that every time you change the battery each new one has a protective seal on it. In cases where the seal is compromised, it is highly likely that the battery will not perform well. All batteries are zinc air, which means they become active when they make first 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.
