Since these cells are no longer available today, this set offers a functional solution. We mechanically adapt modern zinc-air hearing aid batteries (type P312) to the required format.\u003c\/p\u003e\n\u003cp\u003eThe included rubber ring centers the smaller cell precisely in the battery compartment and ensures secure contact. Electrically, the zinc-air cells are the ideal replacement: they deliver a stable 1.35V under load, ensuring correct exposure meter function without complicated adjustment.\u003c\/p\u003e\n\u003cp\u003eNote: Zinc-air batteries are activated by removing the seal.
