One box of 60 Extra Power Size 13 Zinc Air Hearing Aid Batteries per order
Product Information
Featuring with its consumer-focused extra long tabs, Extra Power batteries are manufactured at the world’s most up-to-date and biggest production site for hearing aid batteries in Erlangen, Germany—well recognized for manufacturing quality and detailed precision.
Subject to Germany’s stringent safety guidelines and quality checks, every cell is tested for its electrical and mechanical characteristics in compliance with its specification. A long service life with a guaranteed high cell voltage thanks to a patented cathode technology makes frequent battery changing redundant and promises the best sound.
Extra Power hearing aid batteries provides additional safety even under extreme environmental conditions. Each individual cell is tested for its electrical and mechanical characteristics in accordance with its specifications.
A highly developed film seal for every cell guarantees that the battery does not dry out or drain prematurely. The stainless steel housing provides high-level stability and safe protection against corrosion.
Why zinc air technology?
Zinc air batteries have an especially high energy density and exhibit an almost flat drain curve. They are therefore the ideal power supply, especially for today’s digital hearing aids.
The air holes of the battery are initially sealed with a protective tab. They are kept in this way, in an “inactive state”, until they are needed. The inherent self-drain of zinc air batteries with protective tab attached amounts to a mere 3% a year. The film is removed when the battery is inserted into the hearing aid. After several seconds of activation time, the battery begins to produce current.
In the activated state (with protective tab removed), zinc air batteries can only be stored for a limited period and should be used as quickly as possible.
After removing the tab, please wait for 5 minutes so that the battery can fully activate and function at peak performance.
