In the Triton Hearing online shop, you will find a range of quality hearing aid products.

Hearing aids are becoming smaller and more powerful, regardless of whether they run on standard or rechargeable batteries. When deciding on which battery to buy, it is worth considering type, performance, manufacturer, service life, quality and capacity.

Below you will find all of the information you need to make buying and changing your batteries as straightforward as possible, allowing you to get the most out of your hearing aids!

How do hearing aid batteries work?

Zinc-air batteries are air-activated and will not work until the coloured tab has been removed. Once removed, air can enter the battery cell, producing zinc oxide and generating energy.
It is important that you remove and discard the coloured tab, only when you are ready to use the battery. Replacing the tab will not extend the battery life.

How often do I have to change my hearing aid batteries?

Each hearing aid will take one battery. How often you replace them will largely depend on the battery's size, how long you wear your hearing aid and your hearing aid's performance.

It varies by device, but in general, batteries lengths tend to be:
  • Size 10 - 5 days per battery
  • Size 13 - 10 days per battery
  • Size 312 - 7 days per battery
  • Size 675 - 14 days per battery

What are the different types of hearing aid battery?

Hearing aid batteries are produced by various manufacturers and come in a variety of sizes. 
  • Behind-the-ear (BTE) hearing aids typically take size 13 and 312 batteries
  • In-the-ear (ITE) hearing aids tend to take sizes 312 and 10
  • A more powerful size 675 battery is used in larger models, as it provides a higher energy supply for longer

What size do I need?

If you want to order more batteries but are unsure what size you need for your hearing aid, the old packaging can be helpful. Hearing aid batteries come in four sizes: 10, 13, 312, and 675.

How do I insert the batteries?

  1. Open the battery case and remove the old battery
  2. Remove the protective coloured foil from the new battery
  3. Insert the new battery with the side that had the sticker facing upwards
  4. Close the battery case
  5. Since the battery only begins to work at this point, it may take a few moments before your hearing aid is supplied with power.
  6. Standard hearing aid batteries are not rechargeable and cannot be thrown in your kitchen bin. Order a free battery recycling box from our online shop and when it is full, bring the recycling box to your local Triton clinic!

What are rechargeable hearing aids?

Hearing aids don't always have to be powered by standard, disposable batteries. Rechargeable batteries are an alternative option. One advantage of rechargeable batteries is that they don't need to be changed. Once the battery runs out, you can recharge it overnight.

Your audiologist will be happy to explain which hearing aid models come with rechargeable batteries and whether they would be appropriate for your hearing situation.
