Hearing aid battery RAYOVAC Size 312 (PR41) 1.45V — pack of 8
Disposable zinc-air hearing aid batteries RAYOVAC Size 312 (PR41) provide a nominal voltage of 1.45V and come as a pack of 8 cells. These compact round cells are designed specifically for many in-the-ear and behind-the-ear hearing instruments that require Size 312 power, offering standard capacity for daily use and straightforward replacement in one small package.
RAYOVAC Size 312 hearing aid batteries deliver stable voltage over typical operating periods for common hearing aids and are activated by removing the protective tab for immediate use. The zinc-air chemistry provides a high energy density relative to the cell size, while the standardized Size 312 form factor ensures compatibility with a wide range of hearing device compartments. The 8-cell pack format offers convenient spare capacity for routine battery swaps.
To install, open the hearing aid battery compartment and remove one cell from the pack. Peel off the protective adhesive tab to expose the air inlet; allow the battery to rest for a few seconds so the zinc-air cell activates. Insert the battery with the correct polarity as indicated in the device compartment, then close the compartment. Replace depleted batteries with new cells from the pack to maintain device performance.
Store unused batteries in a cool, dry place and keep them in their sealed packaging until needed. After removing the activation tab, use the battery within the timeframe recommended by the device manufacturer for best life. Dispose of used batteries according to local regulations for battery recycling or hazardous waste.
