Power One Hearing Aid Batteries - Size 312 (p312) - 60 Batteries
- Made in Germany - 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.
- Extreme Reliability - Power One provides additional safety even under extreme environmental conditions thanks to its three-fold sealing design and patented PTFE film technology. PTFE is a very special type of plastics: its also serves as a non-stick coating on pans (as Teflon®) and as a breathable membrane in clothes (as Gore-Tex®).
- Tested - Each individual cell is tested for its electrical and mechanical characteristics in accordance with its specifications.
- Compatibility - Our size 312 Power One hearing aid batteries are compatible with all major hearing aid brands, including Oticon, Phonak, ReSound, Starkey, Widex, Signia, Unitron, and more.

Less plastic waste
I prefer these batteries to Duracell since there’s much less plastic waste in the packaging. Performance seems equivalent. Fast service and good price from Hearing Tracker.
