An alternative to disposable batteries is silver-zinc rechargeable batteries, which can power a hearing aid for a full day, require mere hours to recharge, and only need to be replaced approximately once each year. The drawback is that you’ll need help replacing them once they expire. You should expect to pay between $25 and $100 for a typical hearing aid battery charger.

Additionally, rechargeable hearing aid systems that utilize lithium-ion power packs allow you to simply plug your hearing aids directly into the recharging station to recharge them each night. This eliminates the need to constantly buy new batteries. These systems are better for the environment, as well. In five years, you will probably go through eight rechargeable batteries.
