120-Pack Size 312 Zinc-Air Cells

These PowerOne hearing-aid batteries arrive as 20 cards of six, giving a total of 120 zinc-air cells rated at 1.45 V. They are intended for daily-wear hearing instruments that require the size 312 form factor. The mercury-free chemistry meets current environmental standards. Each card protects the cells until the tab is removed.

Fits Standard Size 312 Compartments

The cells slot directly into any hearing aid designed for size 312 batteries, so no adapter or holder is needed. Removing the protective tab activates the zinc-air chemistry, after which the cell delivers its rated voltage until depleted. Buyers who need a different voltage, a rechargeable format or a larger pack quantity will not be served by this product.

Questions about this item

How long will the 1.45 V zinc-air cells last under daily all-day hearing-aid use?

Actual runtime depends on the hearing aid's current draw; the 120-cell pack (20 cards of 6) is sized to provide months of supply for typical daily wear.

Do the size 312 batteries generate noticeable heat or noise during continuous operation?

Zinc-air chemistry produces no audible noise and negligible heat in normal hearing-aid operation.
