Maxell Hearing aid battery PR41-312

These zinc-air button batteries have been specifically designed for hearing aids, including modern wireless models, and are color-coded for easy identification. Since zinc-air batteries are air-activated, they come with a factory seal to keep them inactive until use. After peeling, oxygen interacts with the zinc in the battery to activate it. To achieve optimal battery performance, wait one minute after removing the battery 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 take the battery out of the packaging. They are mercury-free and more environmentally friendly. Just be sure to dispose of them responsibly.
