Made in Germany, by Power one.

Power one batteries are manufactured in Ellwangen, Germany, at the world’s most up-to-date and biggest production site for hearing aid batteries. They are produced on fully automated high-speed lines. The high degree of automation of this process means that very few manual operations are required – the risk of error is therefore minimal.

Optimum service life and performance

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.

Perfect anti-corrosion protection

The stainless steel housing provides high-level stability and safe protection against corrosion. 100% tested

Each individual cell is tested for its electrical and mechanical characteristics in accordance with its specifications.

Quick activation

A system that has been optimized for extremely low internal resistance will enable the battery to activate within seconds once the tab has been removed.

Long shelf life

A highly developed film seal for every cell guarantees that the battery does not dry out or drain prematurely. This long shelf life has been demonstrated in long-term tests even under extreme climatic conditions.

Award-winning packaging

“comfort tab”: The extra-long tab on every battery can be gripped and removed with ease.

“comfort pack”: The double-walled pack with integrated rotary dispenser safely protects the power one batteries. This is so secure that any accidental removal of the tabs is prevented.

“quality seal”: The quality seal guarantees that all the cells are untouched in their original packaging and have been factory tested. A resealable system allows the pack to be closed again securely whenever a battery is removed.
