You have family, friends, responsibilities, hobbies, and a well rounded life. You don’t have time to put that life on hold to change your hearing aid batteries multiple times a day—and with Powerone rechargeable hearing aid batteries, you won’t have to. These high-performance NiHM batteries ensure you can go all day without recharging, as charges last over 12 hours. Simply pop them into your charger at night (not included), and wake up to fully charged batteries for another day of wherever life takes you. Because your safety is always the top priority, the Powerone Accu plus hearing aid batteries 312 do not contain any heavy metals like mercury, cadmium, or lead. When you choose rechargeable button cells, the environment—and your wallet—will thank you. All power one batteries are subjected to strict safety and quality checks, so you can use them again and again with confidence.
