Kirkland Signature Zinc Air Size 675 hearing aid batteries are designed for use in hearing aids that require size 675 batteries. These batteries utilize zinc-air technology, which activates upon removal of the protective tab, exposing the cell to oxygen and initiating the electrochemical reaction that powers the battery. Each cell delivers a stable 1.45 volts of power.

This 36-pack provides a generous supply of individually packaged batteries for convenient storage and use. The batteries are mercury-free, supporting environmental responsibility, and are manufactured in Germany to high quality standards. Size 675 is one of the most powerful hearing aid battery sizes, typically the largest standard size available, making it ideal for behind-the-ear (BTE) hearing aids and cochlear implant processors that demand extended battery life and high power output.
