Kirkland Signature Size 13 Zinc Air Hearing Aid Batteries are included as a complimentary gift with a qualifying Costco hearing aid purchase. Each pack contains 48 batteries providing reliable, long-lasting power for a wide range of digital and programmable hearing aids.

These mercury-free batteries operate at 1.45 volts and are constructed using zinc air technology, which activates upon exposure to air. Simply remove the pull tab and allow the battery to breathe for approximately one minute before inserting it into your hearing aid for optimal performance. The batteries feature a patented construction designed for consistent power output and a shelf life of 2–3 years when stored properly.

Made in Germany, these batteries are compatible with most hearing aids that use the Size 13 format, identifiable by the orange pull tab color. The 48-count supply provides an extended supply for everyday use.
