Maxell Hearing aid battery PR44-675

These zinc-air button batteries are specifically designed for hearing aids, including modern wireless models, and are color-coded for easy identification. As zinc-air batteries are air-activated, they come with a factory seal to keep them inactive until use. Once unsealed, oxygen interacts with the zinc in the battery, activating it. To achieve the best performance from the battery, wait one minute after removing it to fully activate it before inserting it into your hearing aid. Once activated, the battery remains active until the power is depleted. These batteries are delivered on a wheel, making it easy to remove them from the packaging. They are mercury-free and more environmentally friendly, so just make sure to dispose of them responsibly. Store them at room temperature between 10°C and 30°C for optimal performance.
