VARTA 13 / A13 / PR48 8-pack - Zinc-air Hearing Aid Battery

The VARTA 13 / A13 / PR48 Zinc-Air Hearing Aid Batteries, 8-Pack provides single-use power for audio amplification devices. These button cells use zinc-air chemistry to deliver a capacity of 310 mAh. Each pack contains eight batteries, offering a practical supply of replacement cells for hearing aid users. The size 13 format ensures physical compatibility with devices requiring A13 or PR48 designations. The compact button shape allows for straightforward insertion into designated battery compartments.

A stated storage life of up to four years keeps the cells usable after extended time on the shelf. Manufactured in Germany, the product is designed for standard and high-performance hearing aids, including models that support wireless or Bluetooth streaming. A stable discharge curve supports the continuous current draw required by modern hearing devices. Users must remove the sealing tab shortly before installation to allow ambient air to reach the zinc. This activation starts the chemical reaction that powers the hearing aid.
