Being able to keep in touch and communicate with one another is so important. As we are all being asked to spend more time apart, to reduce the spread of coronavirus (COVID-19) you may be thinking about your hearing aid battery supply and how to get the most from your batteries.

RAYOVAC® is committed to providing our hearing aid battery customers with the power to hear more. To this end, we have put together some answers to questions that our customers are asking.

How can I make my hearing aid batteries last longer?

With encouragement to visit stores as little as possible during this period, you may be wondering whether your hearing aid batteries are lasting for as long as they could be. There are a number of Factors affecting hearing aid battery life.

These include:

  • The size of the battery – the larger the battery the longer it will last, with the size depending on which hearing aid you have.
  • Battery freshness – a fresher battery will provide you with more power for longer. Make sure that you check the best before date on your batteries.
  • The extent of your hearing loss – the more severe your hearing loss, the more power your hearing aid will need.
  • How much you use your hearing aid – the more you use your hearing aid the faster your battery will drain.
  • The environment –Extremes of temperature and humidity (for example in the bathroom) can reduce battery life. By storing your batteries in a cool, dry place (but not in the refrigerator) you will help preserve their power for longer.

You can also ensure that your hearing aid battery lasts longer by switching off your hearing aid when it is not in use or removing the battery overnight.

Please see our FAQ below on where to buy batteries, should you be unable to visit your usual supplier due to COVID -19 restrictions.

How should I store my spare hearing aid batteries?

By keeping track of your usage and making sure to use older batteries first, you can ensure that you have what you need without over-stocking and avoid reduced performance.Our tips for hearing aid battery storage include:
