Kirkland Signature Size 13 Zinc Air Hearing Aid Batteries deliver premium performance through patented battery construction and components, offering the best combination of high power and long life. These 1.45 Volt batteries are mercury-free and made in Germany, designed to improve performance in a wide range of hearing aids including digital, programmable, and those used by individuals who are severely hearing-impaired.

Kirkland Signature's proprietary air-access technology allows each battery to draw on precisely the amount of air needed, maximising power without compromising performance. The result is a more consistent, better-performing hearing aid battery every time. Each battery's pull tab creates an airtight seal that preserves freshness until the battery is activated for use.

The packaging is designed with convenience in mind: large pull tabs make insertion and handling easy, and the dial-style packaging provides secure, portable transport. Each pack contains 48 individually packaged batteries. Safety warning: keep batteries away from small children and dispose of used batteries immediately — swallowing a battery can cause serious injury or death within two hours due to chemical burns.
