The VARTA 312 / A312 / PR41 Zinc-Air Hearing Aid Batteries, 8-Pack contains eight single-use cells for hearing aids. Each cell uses zinc-air chemistry and delivers a nominal 1.45 V. The button-shaped cells fit standard 312 battery compartments. With eight cells per pack, you have enough for regular replacement. Zinc-air remains the standard chemistry for this category because of its energy density in low-drain devices.
Each cell is mercury-free, which reduces heavy metal content. The batteries keep their charge for up to four years when stored in suitable conditions. The leak-resistant construction helps protect hearing aids during normal use. They are made in Germany, in line with regional production standards. The build is consistent enough to give stable power during everyday use.
Key Features:- Suitable for standard and high-performance hearing aids – covers a range of power needs.
- Interchangeable with 312A and DA312 – fits devices using either label.
- 7.8 mm diameter – standard size for 312 cells.
- 3.45 mm height – fits size 312 battery compartments.
