The GP Batteries IC-GP4420 are Zinc-Air batteries specifically engineered for hearing aids. The ZA13 format — also known as PR48, AC13, and DA13 — is one of the most widely used hearing aid cell sizes. The 1.4V Zinc-Air chemistry activates on contact with air and is optimised for the continuous low-current draw typical of hearing aids.

The batteries are non-rechargeable. Do not throw into fire or attempt to open them. Insert with correct polarity and recycle used cells according to local regulations.
