Zinc Air (ZA) Batteries – Ideal for Hearing Aids
These batteries activate when exposed to air and are primarily used in hearing aids and small medical devices. They offer high energy density and steady voltage but must be used soon after activation.
What to Know About Zinc Air Batteries
Zinc air cells are available in sizes like 10, 13, 312, and 675, often color-coded for hearing aid compatibility. Their performance depends on air exposure, so keeping them sealed until use is key. Environmentally safer than many alternatives.
