Hearing aid batteries are the “bane of hearing aid users’ existence.” People have long wanted to get rechargeable batteries for their hearing aids, to avoid the regular swapping of small, fiddly items that some people find hard to handle. But the challenge wasn’t that easy.
Some of the first rechargeable batteries were fine when they were new, but as time progressed these batteries would not hold a charge over a full day. When people can’t rely on their batteries to get them through a day, they resort to carrying non-rechargeable, single-use batteries as a back-up, which defeats the purpose of rechargeables.
The advent of new battery compounds has solved the problem of short charges. Several manufacturers have now introduced new rechargeable hearing aid strategies that last long enough to avoid carrying back-up single-use batteries.
Different manufacturers are following different strategies. Some are using removable batteries designed to be retrofit into existing hearing aids, provided the model is compatible. This is advantageous for users who want the convenience of rechargeable batteries, but who have already invested in new hearing aids recently.
Other manufacturers have chosen to seal their batteries into the hearing aids permanently. This requires users to buy new hearing aids, but additional advantages of these hearing aids include high water resistance, capable of being under water up to 3 feet in depth for up to 30 minutes without damage. Hearing aids like these are well-suited to children, allowing them to “be children,” running through the water splash parks like all their friends.
Rechargeable hearing aids are very popular with seniors whose fingers are not as flexible as they used to be. Just pop the hearing aids into the charger at the end of the day and they’re ready to go after the lights stop flashing.
