Theoretically, re-chargeable batteries for hearing aids are definitely a great idea, but in the past this idea didn’t always succeed in reality. 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 12 to 14 hours of use that hearing aid wearers need, these early batteries commonly lasted only 5 to 6 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. Together, these enhancements propelled rechargeable hearing aid batteries so far forward that they are now more eco-friendly and often more cost-efficient than disposable batteries. To emphasize these two qualities, during a 3-year span a binaural (both ears) hearing aid user will go through an average of 300 disposable batteries, which would have to be replaced at a cost of 300 to 400 dollars, and would have to be disposed of. In the same time period, the cost of rechargeable batteries (plus the charger) would be about $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 70, who just happen to be the primary wearers of hearing aids. With some rechargeable hearing aids, you don’t even need to open them to remove the batteries; simply place the entire aid in a recharging unit over night, and it’s all done for you automatically. 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. And, you can always revert to disposable batteries in a pinch. If you don’t have access to your charger, just pop in a few disposable batteries in the meantime.
