Renata Size 675 1.45V Zinc Air Hearing Aid Batteries (12 Pack)

Renata batteries are characterized by offering a wide range of applications and their long operating life. Our newest generation not only meets the highest requirements in the industry today, but is also optimally suitable for analogue and digital, as well as for ultra-high-power hearing aids. Our zinc - air batteries are designed for high currents and are valued in particular for their extra - long operating life.

Oxygen is the energy source for our zinc - air batteries.  Oxygen from the ambient air reacts with the zinc in the interior of the battery and generates a current.  In its original packaging, the battery is sealed by an adhesive strap that protects it against environmental factors.
