In the past, the theory of rechargeable batteries for hearing aids was an idea that was much better in principle than it was in practice. Early rechargeable hearing aid batteries were so large that they could only be used in over-the-ear type aids; they also took hours to recharge and then didn’t hold a charge for very long. Instead of the twelve to fourteen hours of use that hearing aid wearers need, these early batteries commonly lasted only five to six hours.
Numerous technological advancements were needed to make rechargeable batteries a practical option. Batteries became smaller and held a charge longer. And the rechargers themselves were redesigned. All of these changes add up to making rechargeable batteries more eco-friendly and cost-efficient, and thus an excellent choice for use in your hearing aid. For example, over a three-year period the average hearing aid wearer would use up an average of three hundred disposable batteries at a cost of $300 to $400 dollars; all of these batteries would have to be disposed of in a proper recycling bin and not just thrown in the trash. In contrast, the hearing aid wearer using rechargeable batteries would only need 6 of them for that same three-year period, none of which needed to be thrown away; total cost (including the recharger) would be in the range of 100 to 200 dollars.
Other benefits of rechargeable batteries include, interestingly enough, having to open fewer sealed-tightly-in-plastic-to-avoid-easy-access battery packages, which can often be a challenge for those over seventy, who just happen to be the primary wearers of hearing aids. In contrast, some of the newer aids that use rechargeable batteries, don’t even have to be opened. You simply place the entire unit into the recharging station overnight. There are even portable battery rechargers, the size of a pen, which you can use anywhere because they don’t need to be plugged into a wall socket.
Rechargeable hearing aid batteries may have gotten off to a rocky start, but today that are an excellent viable option. They will help you save money and reduce waste. In addition, using rechargeable batteries does not mean you lose the option of using disposable ones; if you’re stuck somewhere without your charger, you can just buy disposable batteries and still use your hearing aid successfully.
