Question: Which is better the rechargeable battery hearing aids or disposable batteries?
Answer: They both have great performance, and there are advantages to each. The rechargeable battery hearing aids are easy to store at night. With no off/on function, simply place them in the charger, and they are ready the next morning with a charge that can last up to 30 hours in some hearing aids. However, if you need to turn them off, you will push a button for five seconds instead of opening the battery door. If your hearing aids are battery-operated, not rechargeable, you’ll replace the batteries every three to ten days, depending on the hearing aids. You will also need to keep extra batteries nearby at all times. There’s no charger needed when traveling, so think of your lifestyle before making a decision.
