Rayovac is an established American battery brand with a long-standing reputation for hearing aid batteries, supplying sizes 10, 13, 312, and 675 to suit the most common behind-the-ear, in-the-ear, and receiver-in-canal devices. The zinc-air cells are designed to deliver consistent power output across the full battery life, making them a practical choice for everyday hearing aid users who depend on reliable performance. Size 312 and size 13 remain the most widely used formats in modern hearing aids, though the correct size depends entirely on the device manufacturer's specification - the battery door number or the existing cell packaging will confirm which is needed. Rayovac batteries are non-prescription consumer products and carry no medicinal claims. Ronaghan's Pharmacy stocks Rayovac hearing aid batteries for straightforward collection or delivery.
