Hearing Aid Battery GP ZA 312 1.4 V Zinc-Air, 6 pcs (GPZA312978C6)

GP ZA 312 zinc-air hearing aid batteries deliver a nominal voltage of 1.4 V in a compact size 312 format. Supplied as a pack of six disposable cells, these batteries are intended for use in many behind-the-ear and in-the-ear hearing aids that accept size 312. Zinc-air chemistry provides a steady operating voltage and a capacity suited to typical daily use in personal hearing devices.

Advantages

These GP ZA 312 batteries offer consistent voltage output and a chemical design that activates when exposed to air, helping to preserve shelf life until first use. The small size is compatible with a broad range of hearing aid models that specify size 312 cells. The six-pack format supports short-term replacement needs and makes it easy to keep a small stock for daily use.

Suitable for

• Behind-the-ear (BTE) hearing aids that require size 312 batteries
• In-the-ear (ITE) and receiver-in-canal (RIC) devices compatible with 312 cells
• Everyday use where stable voltage and predictable runtime are required

When it may not be suitable

This product is not intended for rechargeable hearing aids or devices that require other cell sizes. It may not be appropriate for users who need extended high-capacity runtime beyond typical daily usage, or for devices with very high current draw that recommend larger or special-purpose batteries.

Key specifications

• Cell chemistry: zinc-air
• Nominal voltage: 1.4 V
• Cell size: 312 (standard hearing aid size)
• Quantity: 6 disposable cells per pack

How to use

Remove a cell from its packaging and keep the protective tab in place until ready to use. When you are ready to install the battery, peel off the tab to expose the air inlet; the battery will activate and begin to deliver voltage. Insert the cell into the hearing aid following the device manufacturer's orientation instructions. Replace batteries individually as they deplete and dispose of used cells according to local regulations for household batteries.

What to consider before purchase

• Confirm your hearing aid model accepts size 312 batteries
• Consider how many batteries you use per week to determine how many packs you need
• Check storage conditions — keep unused cells in a cool, dry place to preserve shelf life

Usage recommendations

Store unopened packs at room temperature and avoid excessive heat or humidity. Peel the activation tab only when you are ready to use a battery, and carry spare cells in a protective case to prevent accidental activation. Replace batteries promptly when audio performance diminishes to ensure reliable hearing aid function.
