Single-use battery GP Batteries ZA312
The GP Batteries ZA312 is a single-use Zinc-Air button battery designed for hearing aids that require PR41 (also called ZA312) size cells. With a diameter of 7.9 mm and a height of 3.6 mm, this battery is supplied in a blister pack of six cells and provides stable 1.4 V output suitable for a wide range of sensitive hearing devices.
These GP hearing aid batteries deliver long-lasting power and consistent voltage output thanks to Zinc-Air technology. They are manufactured to precise quality standards to ensure reliable performance across major hearing aid models and come in a compact blister pack for convenient storage and handling.
Remove a cell from the blister and peel off the protective tab immediately before inserting it into the hearing aid. Ensure the battery is seated with correct polarity and wait a few seconds after activation for the Zinc-Air cell to reach full performance. Replace batteries in all compartments at the same time if recommended by the device manufacturer.
Store unused batteries in a cool, dry place and avoid exposure to extreme temperatures. Dispose of used Zinc-Air cells according to local battery recycling regulations. If device performance seems reduced, check that the protective tab has been removed and that the battery is correctly installed.
