Description

This set lets you power your analog camera with modern zinc-air technology. The rubber ring centers the smaller 675 battery in the PX625 battery compartment. Since zinc-air batteries have a voltage of 1.4V (very close to the original 1.35V mercury batteries), the light meter works accurately again. Conventional 1.5V alkaline batteries would cause exposure errors.

Please note: Zinc-air batteries are activated by removing the sticker and need air to operate. They have a lifespan of about 3–6 months after activation.

Suitable for cameras that draw battery power from contacts at top and bottom:
