Made in Germany, the Power One Zinc-Air Hearing Aid Battery is mercury-free and designed to be both durable and environmentally friendly.

Batteries typically last about 7 to 10 days. The actual battery life is affected by hearing aid usage.

Each package includes 60 individual hearing aid batteries. Power One batteries feature stainless steel casing to provide protection against corrosion. The three-fold sealing design and PTFE film technology increases reliability. Shelf-life loss of less than 2% per year when stored at room temperature.

For best results: After removing the adhesive tab, let a new battery sit for at least one (1) minute before inserting it into the device. Keep batteries stored in original packaging with a tab on until use.
