Traditionally, hearing aid batteries required replacement every one to two weeks. Many of today’s products offer rechargeable options, essentially eliminating the need for regular battery changes. Many rechargeable batteries can provide up to 24 hours of hearing from a single charge. The benefits of rechargeable batteries are plentiful: You don’t need to worry about having extra batteries on hand. You will save time and money by not having to purchase disposable batteries. Your charger will serve as your devices’ overnight home for safe and dry storage.
