- Stable 1.35V like the original: 675 zinc-air batteries inherently provide the exact voltage your camera’s light meter needs for accurate readings.
- Replacement for the dead PX1/MR50: The adapter ensures a perfect mechanical fit, while the zinc-air battery supplies the voltage of the no longer available 1.35V mercury battery.
- No 1.5V misreadings: Modern 1.5V alkaline batteries fool the light meter; the zinc-air cell instead maintains a constant 1.35V.
- Ready to install: Adapter and matching batteries included – just insert and shoot.

Description
The original 1.35V mercury batteries (PX1/MR50) are no longer available. Using common 1.5V alkaline batteries instead fools the light meter – readings become inaccurate. This adapter solves that: it holds a 675 zinc-air hearing aid battery, which inherently provides a constant voltage of exactly 1.35V.
The adapter ensures the mechanical fit in the battery compartment, while the zinc-air cell provides the correct voltage. Matching batteries are included – ready to use right away.
