As a consequence of these various factors, we recommend that you familiarize yourself with your device’s low battery warning notification process. After a while, you will become accustomed to the duration to expect for your particular hearing aid and its typical usage pattern.

A hearing aid uses on average about one battery per week and you need one hearing aid battery per hearing aid. Some hearing aids with very small batteries may only provide 4 days of use whereas ones with larger batteries may last up to 2 weeks. Like most technology devices, your hearing aid batteries provide power to your digital hearing aids and, therefore, assist your hearing needs every day. Historically, these types of batteries are accessed through a small battery compartment door that you have to change every few days or weeks. Now all hearing aid manufacturers offer rechargeable battery models within their portfolio. Even today there is no solid evidence that you can extend non-rechargeable battery life. However, to maximize the lifespan of your hearing aid batteries, it is important to handle them carefully and store them in a cool, dry place. Now zinc-air batteries are commonplace, as they are more eco-friendly and maintain reliable voltage. These use oxygen from the air as an electrolyte. These batteries have a longer lifespan than zinc-carbon batteries and can provide more power, making them a good choice for advanced hearing aids. However, they can be more expensive and may be more difficult to find in some areas.Are hearing aid batteries free on the NHS? The simple answer is yes, you can get free hearing aids, free NHS hearing aid batteries and repairs from the NHS. However, this is only the case if you have and currently wear NHS hearing aids. They will also give you the right advice about battery size, brands and maintenance tips - so you will always benefit from the right hearing aid battery. What are the four main hearing aid battery sizes and what is the colour-coding for hearing aid batteries? Here we breakdown the coding:

So, do hearing aid batteries expire? Rechargeable batteries need to be charged fairly regularly and standard batteries are disposable and need to be replaced. Rechargeable hearing aid batteries have a shelf life too but are generally the same as the device itself - roughly 4-5years. In a world where convenience is key, we don’t think the consumer attraction for this will change as portable recharging pods continue to become smaller providing handy on-the-go charging.

It is also a good idea to clean the battery compartment of your hearing aid regularly to remove any dirt or debris that may affect the battery's performance. The below advice will help get the most out of your hearing aid batteries. Generally, Zinc-carbon batteries typically last from 4 to 14 days, while rechargeable batteries can last from 4 to 7 days on a single charge.

Hearing aids don’t always have to use standard batteries or disposable batteries, there are rechargeable versions available – so they can be recharged. These are simply called rechargeable hearing aid batteries or lithium-ion batteries and pretty much all hearing aid brands have these as an option in their device ranges. It is important to store hearing aid batteries properly to ensure they last as long as possible. Store them in a cool, dry place and keep them away from metal objects. If you're not going to use your hearing aid for an extended period of time, remove the battery to prevent leakage.For all generic and standard hearing aid batteries, it really depends on the type of hearing aid that needs powering and its overall capacity, how often you are wearing your hearing aids and how much you stream via Bluetooth connectivity. This is also a similar case for rechargeable hearing aids. With rechargeable hearing aid batteries, you don’t have to buy new batteries when your old ones run out of power. You just recharge them and go! Rechargeable batteries should last as long as the life of your hearing aids. What is the cost of hearing aid batteries? Leave the door open: When you’ve taken your hearing aids off, turn them off and open up the battery compartment door. It reduces battery drain and helps trapped moisture escape, so the hearing aids are less likely to get damaged or the battery corrode. The tester is easy to use: Simply insert hearing aid battery and the LCD digital display lights up to show the charge level with an ascending bar.

Invest in a dehumidifier: This will help absorb any moisture that is hidden in your hearing aid and battery. Your battery power will be used to its full potential and it’s also a safe place to store your devices especially if you don't have a charging pod. We are generalising on the above, lifespan will also depend on your usage and streaming trend but usually the smaller the battery the shorter the lifespan. If out of the blue, your hearing aid battery life is shortened, there might be an issue with your aid. There are also rechargeable hearing aid batteries, which can be convenient for users who do not want to constantly replace disposable batteries. These batteries can be charged using a specialised charging unit and may be suitable for use in both traditional and advanced hearing aids.Hearing aid batteries come in different sizes, which are denoted by a number and colour code. The most common sizes are 10, 13, 312, and 675. The size of the battery you need will depend on the size of your hearing aid. Your hearing aid manufacturer or audiologist can tell you which size you need. Historically, the main types of hearing aid batteries are zinc-carbon batteries, which are made from a combination of zinc and carbon. These batteries are inexpensive and widely available, but they have a shorter lifespan than other types of batteries and may not be suitable for use in advanced hearing aids that require a higher level of power. If the battery compartment in your hearing aid doesn’t have a door, then it has a lithium-ion rechargeable battery inside. This means that these batteries take about 3-4 hours to fully charge and can usually last you around 24 hours.
