Rayovac 312 Long Lasing Hearing Aid Batteries (4-pack) - Preferred by Most Audiologists

All hearing aid batteries are not created equal! Part of Sonic Alert's quality assurance is the added convenience of longer battery life. We spec and use 312 zinc air batteries as the first choice, as they last approximately ten days, while a #10 battery lasts about half as long (3-5 days). In addition to longer life, 312 batteries also provide more power which further enhances background filtering, providing more crisp hearing.
