Choosing a battery

What size/type of battery do I need?

Every battery has a number and a colour. The colour of the sticker on the battery indicates the type:

For hearing aids:

• 10-yellow                                 (height:  3.6 mm, diameter: 5.85 mm)
• 13-orange                                (height: 5.4 mm, diameter: 7.90 mm)
• 312-brown                                (height: 3.6 mm, diameter: 7.90 mm)
• 675-blue                                   (height: 5.4 mm, diameter: 11.6 mm)

For the speech processor of a cochlear implant (CI):

• 675+/CI light blue/grey/green (height: 5.4 mm; diameter: 11.6 mm) specifically for CI

This information will be indicated on the battery and on the packaging of the battery. To find out which battery you need, you can consult your hearing aid's instruction manual or ask your hearing care professional or ENT doctor. We have also made an overview for you with all the different battery codes (battery code page).

 

Can I use rechargeable hearing aid batteries?

You can use rechargeable batteries if your hearing aid does not have a high rate of power consumption. If your batteries currently last ten or more days, then rechargeable batteries are worth looking into. 

 

Which brand of battery should I use?

We supply all the main brands of hearing aid batteries. Which is the best for you depends on how you use your hearing aid. If you know which size of battery you need it is easy to make a choice based on price and quality.

If you would like to test out different batteries to see which performs best, you can order a sample pack containing multiple brands of batteries. 

 

Which batteries are best to use with more powerful hearing aids?

If you use more powerful hearing aid it's best to go with one of the more expensive batteries. These are the more powerful ones. If you would like to test out different batteries to see which performs best, you can order a sample pack containing multiple brands of batteries. 

 

Which brand should I choose if I'm travelling to a warm and humid climate?

Batteries can oxidise slightly in a warm and humid climate. This can damage your device. The best battery to use in a warm and humid climate is the Power One because this battery is guaranteed not to oxidise. Keep in mind that batteries don't last as long in extreme temperatures. 

 

Which batteries should I use for a cochlear implant (CI)?

For this you should use high capacity 'Implant Power' batteries (675+, these usually have a light blue, grey or green sticker) A cochlear implant usually requires two or three batteries. When you replace these batteries, replace them all at the same time to maintain good performance. When replacing the batteries, it's best to switch off the processor. This is better for the lifespan of the batteries.

 

Battery use

Why do I always have to wait 1-2 minutes after removing the battery sticker?

When you remove the sticker, oxygen comes into contact with the battery. This oxygen activates the battery. The battery requires 1-2 minutes to become fully activated. If you place the battery into the device straight away, power is immediately drawn from the battery and the battery will subsequently supply less energy. 

 

What's the best way to store my batteries?

Keep the batteries in a dry place at room temperature. Never put your batteries in the fridge as this will cause them to create condensation when they are removed, which can damage the batteries. 

 

What should I do if I'm not planning on using my hearing aid for an extended period?

If you are not planning on using your hearing aid for an extended period, you should remove the battery from the device. The battery may otherwise oxidise and possibly damage your hearing aid. 

 

Will my batteries last longer if I replace the sticker whenever I'm finished using the hearing aid?

No.  The battery is activated when the sticker is removed. Replacing the sticker each time will have no effect. 

 

What can I do to protect the environment?

Mercury-Free batteries are the most environmentally friendly choice of battery. All batteries are of the zinc-air kind and are therefore the most environmentally friendly. When the battery is fully discharged,

the battery consists of the metal casing, the internal zinc and less than 1% mercury. The materials are easy to sort and recycle.

Used batteries and rechargeable batteries are classed as hazardous waste. For this reason, to dispose of them, please take them to a battery collection point, e.g. your local supermarket. The metal casing and the zinc can then be reused by the manufacturers. 

 

How do I know if my batteries are still carrying sufficient charge?

The handiest way is to use a battery tester. It's easy to know when the battery is fully discharged as your hearing aid will stop working. Most hearing aids will emit a beep when your batteries are almost completely discharged. 

 

How many days will a battery last in a hearing aid or in the speech processor of a cochlear implant?

This depends on a number of factors:

• the number of hours that you use your hearing aid each day

• the amount and type of noise in your environment
• the age and model of your hearing aid
• the program settings and volume
• the strength and quality of the battery
• the kind of battery: rechargeable, zinc-air or mercury-free
• the temperature and the degree of humidity of your environment
• the way in which the batteries are kept (in a dry place at room temperature)
• whether you correctly wait 1-2 minutes after removing the battery sticker before using the battery

For speech processors: The lifespan for processors with 3 batteries is between 2 and 3 days for most users. The lifespan for processors with 2 batteries is between 1 and 2 days for most users. 

 

Why do hearing aid batteries discharge faster than other batteries?

A hearing aid battery is smaller than other batteries and therefore has a reduced capacity. In addition to this, a hearing aid battery is used intensely all day. This is not the case for most other batteries.

 

Accessories

Why should I use a hearing aid dryer?

Hearing aid dryers extend the lifespan of your hearing aid. What's more, it turns out that you can extend the lifespan of your batteries by 10 to 20%. The reason for this is that a hearing aid consumes less energy when it is completely dry. You can leave the battery in the hearing aid when you use a hearing aid dryer. Do leave the battery compartment open however. 

 

What is a cerumen (earwax) filter and when should I replace it? 

A cerumen (earwax) build-up can result in reduced performance from your hearing aid. Earwax can find its way into in-the-ear (ITE) hearing aids. With the aid of a cerumen filter, you can protect your ITE hearing aid.

We advise you to check each day whether your cerumen filter is indeed of replacement. This is done by checking whether a build-up of earwax is present. If you notice that the performance of your hearing aid is getting worse, it may also be time to replace the filter.
