Power One Evolution Size 10 Zinc Air Hearing Aid Batteries (12 Batteries)

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. This process's high degree of automation means that very few manual operations are required - the risk of error is minimal. Everything from one source: Power One is the only manufacturer worldwide to supply a range of rechargeable batteries, innovative chargers, and zinc air batteries. 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 plastic: it also serves as a non-stick coating on pans (as `Teflon®`) and as a breathable membrane in clothes (as `Gore-Tex®`).
