Duracell DURDA312B16ZM09 Hearing Aid Battery 1.45 V Zinc Air 312 185 mAh

The Duracell DURDA312B16ZM09 is a size 312 hearing aid battery with zinc air chemistry, rated 1.45 V with a 185 mAh capacity. Supplied 16 per pack, 36 packs per case.

Size 312 sits in the middle of the hearing aid battery range and is, by volume, the most widely used of the three. At 185 mAh it carries nearly twice the capacity of a size 10 while remaining small enough for in-the-canal aids — which is precisely the compromise most hearing aid designs settle on. Size governs everything in a device worn inside the ear, and 312 is where acceptable runtime and acceptable physical size meet for the majority of wearers.

Zinc air chemistry means the cell draws oxygen from the surrounding air through ports in its face, sealed at the factory by a coloured tab. The battery is inert while tabbed and activates the moment the tab is pulled — permanently. Replacing the tab does not pause it. Cells should therefore be left sealed until they are going into the aid, and a partly used cell cannot be shelved for later.

The tab colour is standardised across manufacturers, which lets a wearer identify size at a glance without reading print on a cell smaller than a shirt button.

The 16 per pack, 36 per case format suits pharmacy, audiology practice, and retail distribution.

Users include hearing aid wearers, audiologists, pharmacies, and care facilities.

Verify the size required against the specific device before ordering.
