Hearing Aid Batteries Panasonic PR 312 Zinc Air 170 mAh — 6 Pack

Panasonic PR 312 Zinc Air hearing aid batteries come in a pack of six and provide a nominal capacity of 170 mAh. These size 312 cells use zinc-air chemistry to supply stable voltage suitable for many behind-the-ear and in-ear hearing aids. The design includes easy-to-peel activation tabs and a standard diameter and height for straightforward replacement and compatibility with devices that accept PR 312 batteries.

Advantages

Zinc-air chemistry offers consistent output voltage while in use, supporting clear audio reproduction and reducing fluctuations as the cell discharges. The nominal 170 mAh capacity balances runtime and compact size, making the batteries suitable for daily use in small hearing instruments. Packaging in a six-pack allows multiple replacements without immediate repurchase and the peel-tab activation minimizes risk of premature activation.

How to use

Remove one battery from the sealed packaging and keep it in its foil until ready to use. Peel off the tab to activate the zinc-air cell and wait a few seconds for full oxygen exposure before inserting the battery into the hearing aid.
