How to Test, Buy and Change Hearing Aid Batteries

When you start using hearing aids, your audiologist will provide you with information about cleaning and storing your hearing aids and changing the batteries. Hearing aid batteries need swapping on a regular basis, so it’s useful to know how to test, buy and change them. Once you start wearing hearing aids, you’ll soon get used to looking after the devices and you’ll be able to change the battery in a matter of minutes. If you’re new to using hearing aids, or you’re looking for some tips and tricks to get the best out of your batteries, here’s a handy guide to testing, buying and changing hearing aid batteries. 

Testing hearing aid batteries

It’s always a good idea to test your hearing aid batteries to make sure they have run out before you replace them. There are two ways to test a battery. You can use a battery tester and read the result on the display, or you can place the battery inside the hearing aid, put your hands around the hearing aid and move it close to your ear. If you can hear a high-pitched sound, this means that the battery is working. The lifespan of batteries varies according to the type of battery you buy, but if you purchase the same battery every time, you should have a good idea of how often you need to replace empty batteries. Some hearing aids will beep when the battery needs changing. In this case, the beeps will appear sporadically before a series of beeps indicates that the battery has run out. 

Buying hearing aid batteries

When you start wearing hearing aids, your audiologist will talk to you about hearing aid batteries. Hearing aid batteries come in a range of sizes, and the size you need will usually be dictated by the type of hearing aid you have. Your audiologist will be able to advise you which batteries you need to buy for your hearing aid. Hearing aid batteries are color-coded to make it easy to decipher which one to purchase. 

Changing hearing aid batteries

If you’re not using to changing hearing aid batteries, there’s nothing to worry about. Your audiologist will show you how to replace old batteries, and after a couple of attempts, you should find the process straightforward and stress-free. Before you take the old batteries out, make sure they are empty. If they are, remove them and dispose of them safely. When you’re ready to place the new batteries inside the hearing aid, follow these steps:

1. Check the expiry date of your new battery
2. Remove the protective tab from the new battery
3. Leave the battery for three to five minutes
4. Place the battery inside the chamber with the plus and minus signs in the right place
5. Close the battery chamber door
6. Turn your hearing aids on

It’s a good idea to leave your batteries for a few minutes once you’ve removed the tab, as this enables the batteries to become activated. Most hearing aids now have zinc-air batteries, and the zinc is activated by the air to create zinc oxide. This produces energy for the hearing aid. 

Getting more out of your hearing aid batteries

When you buy batteries on a regular basis, it’s understandable to want to get the best out of them. Here are some useful tips to prolong the lifespan of your hearing aid batteries:

• Use new batteries first, and avoid buying in bulk. Hearing aid batteries have a long shelf-life, but the power drains over the course of time. It’s best to have a single spare so that you don’t spend money on batteries that won’t perform at the highest level. 
• Take your batteries out when you’re not using your hearing aids; if you don’t plan to use your hearing aids for a prolonged period, removing the batteries can help to extend their life expectancy.
• Wash your hands when handling the batteries; batteries can become damaged and contaminated by grease, dirt, and dust, so try and wash your hands before replacing or removing them. 
• Store your hearing aids in a dry, safe place; excess moisture is a real problem for hearing aid batteries, so make sure you keep your hearing aids in a dry, safe place. Using a hearing aid dehumidifier can also help.
