We know that battery preference will be a personal choice based on a number of factors such as price, number of cells needed, as well as brand loyalty. That is why we recommend starting with a trial pack. These trial packs let you try each battery brand without buying a whole pack of each. You can then make an informed decision on the best ones for your device.

How to make your batteries last longer

Providing your hearing aid with good batteries is the first step in guaranteeing that you will get the most benefit from your hearing device. You should also consider taking care of your batteries so you can prolong their life and performance.

Batteries used in hearing aids are mainly “Zinc Air”, i.e. the battery is activated when the zinc in it reacts with the air. This type of technology allows it to accumulate large amounts of energy. You will need fewer battery replacements and you will enjoy the clearer sound.  In order to minimize 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 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.
