## Long description

These RAYOVAC zinc-air button batteries are single-use cells designed for hearing aids and other small, low-drain devices that accept PR41 (often labelled 312) size. They use zinc-air chemistry to deliver a stable nominal voltage of 1.45 V and are supplied in a blister wheel for convenient removal. The cells are lightweight and compact, with dimensions suitable for modern hearing instruments and compact electronics.
Advantages
Zinc-air construction provides consistent voltage during use and a high energy-to-size ratio suitable for low-drain devices. The batteries are mercury-free and come on a peel-off wheel that keeps cells sealed until activation. A factory seal prevents air contact during storage; once removed and exposed to air, the cell activates and is ready for use after a short wait.
Suitable for
Hearing aids, including wireless models that connect to smart devices
Small personal audio devices and accessories
Compact medical or assistive devices requiring PR41/312 cells
When it may not be suitable
These zinc-air PR41 cells are intended for single-use applications and for devices that accept air-activated chemistry. They are not suitable for devices that require rechargeable cells or for high-drain electronics that demand sustained high current output.
Key specifications
Cell type: zinc-air, single-use
Nominal voltage: 1.45 V
Size: PR41 (commonly labelled 312)
Dimensions: height approximately 3.6 mm, diameter approximately 7.9 mm
Weight: approximately 0.58 g per cell

How to use
Remove a cell from the blister wheel and peel off the protective seal to activate it. After removing the seal, wait about one minute to allow oxygen to fully penetrate and the cell to reach optimal output, then insert it into the device according to the manufacturer’s orientation. The battery will remain active until its energy is depleted; dispose of used cells responsibly according to local waste regulations.
What to consider before purchase
Confirm your device requires PR41/312 zinc-air single-use cells
Check compatibility with air-activated batteries and the device’s recommended chemistry
Consider storage conditions—store sealed cells at a stable room temperature between 10°C and 30°C
Usage recommendations
For best performance, activate the battery by removing the seal and wait one minute before insertion. Do not expose sealed cells to air until ready to use, and dispose of spent batteries in accordance with local regulations rather than household waste.
