5 Tips To Extend The Life Of Your Hearing Aid Batteries

Hearing aid batteries will be a regular purchase for many of you. If you have recently bought from our Rayovac hearing aid batteries collection, you may have found this information at the exact right time. We have put together our best advice to help you get the most out of each and every cell:

Our Tips:

1. Wash your hands before handling the batteries
2. Keep them away from other metals
3. Only remove the tab when you plan to use that battery
4. Let them air for 30 seconds - 1 minute
5. Open the battery drawer FULLY when not in use

Wash Your Hands Before Handling The Batteries

We have learned that dirt can come from a range of sources, taking off our shoes, shaking someone else's hand, putting dishes into the dishwasher and much more.If any of this dirt touches the battery, it could cause corrosion, shortening the length of your battery more than normal. Clean your hands before touching the batteries to prevent any unnecessary damage. Make sure to also keep the battery away from mouths or dirty surfaces.

Keep Hearing Aid Batteries Away From Other Metals

If you have bought hearing aid batteries before you will notice that they come in a packet that prevents them from touching each other. This is because if they come into contact with other metals, they could short-circuit, rendering them useless.

While the urge may exist to have a pile of spare hearing aid batteries lying around for convenience, keep them in the packet if doing so. Also, keep the batteries away from other metal objects like coins or keys as this could also short-circuit the hearing aid batteries.

Only Remove The Tab When You Plan To Use The Battery

You will notice that hearing aid batteries come with a tab seal, this is to prevent the zinc from mixing with oxygen before use (thus starting the degrading process).

This is why it’s important to only remove the tab just before you are ready to use that individual battery. Once you remove the tab, let the battery breathe.

Let Them Air For 30 seconds to 1 minute

The key is in the name. One of the classic tips for extending the life of hearing aid batteries is to let them air once you’ve opened the tab but before inserting them into your devices.

The standard voltage of Rayovac hearing aid batteries lies between 1.0-1.25 volts. However, let your batteries mix with the air for at least one minute, and this voltage increases to 1.4 - 1.45 volts.

Open The Battery Drawer Fully When Not In Use

When you take your hearing aids out at night to go to bed, some people only slightly open the battery drawer. However, opening up the battery drawer the full way gives the moisture inside the best chance to escape.

By extending the life of your hearing aid batteries, you can save yourself a lot of money in the long term. Think about if you extended every battery you had in one pack by a few days and how much this would add up for each cell you have purchased.

Another option to save money on hearing aid batteries is to go rechargeable. We stock a range of rechargeable hearing aids from Phonak, Signia and Resound, all with an array of benefits.
