Power One EVOLUTION Size 312 Hearing Aid Batteries - Improved Battery Life
Power One EVOLUTION Hearing aid batteries with highest energy density are the result of consistent research work and ongoing development. Our expertise here is based on the synergy of wide-ranging material research, many years of experience in cell development and our own manufacturing plant technology. Our newest development is the power one EVOLUTION, based on TFT (Thin Foil Technology). It has a very high energy density, more capacity than our well-established hearing aid batteries and therefore a longer operating life – by up to 15%.

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®`).
