Hearing aid batteries are an essential part of your hearing aid as they are the engine that makes them work. But which ones are the best?
We know that hearing aid battery preference will be a personal choice for budget, and hearing aid fit. That is why we recommend starting with a hearing aid battery trial pack. This trial pack lets you try each battery brand without buying a whole pack of each.
You can buy a trial pack of batteries in different sizes:
Using high quality batteries is crucial for the maximum performance of your hearing aid regardless of its model. The best hearing batteries are ones that offer a balance of premium quality and price including the battery brands such as Rayovac, Panasonic, Duracell and Power One, all of which you can buy here.
Which batteries are suitable for hearing aids?
Batteries that are used for hearing aids come mainly in four sizes for the different devices. Most companies have unified the names and the colours so regardless of the brand if you know either the number or the right colour for your hearing aid you can never buy a wrong battery type. The four sizes are 13 (orange tab), 312 (brown tab), 10 (yellow tab), 675 (blue tab).
Taking care of hearing aid batteries
Providing your hearing aid with good batteries is the first step in guaranteeing that you will benefit most from your hearing device. You should also consider taking care of your batteries so you can prolong their life and performance.
Hearing aid batteries are mainly “Zinc Air” batteries, i.e. the battery is activated when the zinc in it reacts with the air. This type of batterie’s technology allows it to accumulate large amounts of energy. You will need fewer battery replacements and you will enjoy clearer sound. In order to minimise battery depletion before it is put in the hearing aid, each battery is sealed with a tab and only after its removal does the battery become active. However, you cannot preserve it if you put the seal back. That is why it is best to remove the tab when you need to use the battery. In addition, be careful not to mix old and new batteries or keep them among metal objects, because this may result in a foreshortened battery life.
Another reason to take good care of your batteries, besides prolonging their life, is to protect your hearing aid from damage.
- Always store your hearing aid batteries at room temperature and do not expose them to extreme heat or cold.
- Replace them after you sense that amplification has become diminished or the sound is distorted . Continued use of drained batteries may damage your hearing aid.
- Minimize battery depletion by opening the battery door and leaving it to dry overnight.
- Always replace batteries with clean hands as any dirt on them may harm your hearing device.
How long do hearing aid batteries last?
Depending on the type of hearing aid – analogue or digital, the total hours it is turned on and the amplification level, batteries can last from a week to a few months. If you are not sure what brand is right for you, try batteries from different manufacturers to help evaluate which suits you and your specific hearing aid use best.
