PowerOne P675 Hearing Aid Battery (6 Batteries pack)

6 batteries in 1 packet Optimum Service Life & Performance Extreme Reliability Perfect Anti-Corrosion Protection Mercury Free - Hg 0% Wireless Approved    Type Designation p675 Type No. 24600 Voltage (V) 1.45 Electrochemical system Zinc Air Typical capacity (mAh) 650* Diameter (mm) 11.6 Height (mm) 5.4 Weight (g) 1.83 *180 Ohms 12h/day to 0.9V at 20°C / 55% r.h.   :::Quality 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®`).     :::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. "power 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   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.
