VARTA 675 / PR44 - Hearing aid battery

The VARTA 675 / PR44 Zinc-Air Hearing Aid Batteries, 6-Pack provides single-use power for hearing aid devices. These button cells use zinc-air chemistry that activates on exposure to air. They are made for hearing aids requiring the 675 or PR44 format. A nominal voltage of 1.45 V suits standard hearing aid electronics. This configuration is compatible with the audio amplification components in modern hearing instruments.

The construction contains no mercury, which addresses household disposal and environmental safety concerns. The cells are interchangeable with any device specifying A675, 675, or PR44 power sources. Users can match the designation printed inside their hearing aid battery compartment. Made in Germany, production follows consistent material regulations. The chemistry provides a steady discharge rate suitable for continuous daily operation.
