This Wein MRB625 1.35V Zinc-Air Battery replaces PX625, PX13, and MR-9 batteries and is ideal for camera exposure meters that used to use the old mercury batteries that are now discontinued.
- Equivalent to PX625, PX13, PX67
- Voltage output is more stable than alkaline replacements
- No adjustments or adapters are required
- Up to 10-year shelf life: Wein cells are not activated until the pull tab is removed (removing the battery and replacing the tab prolongs battery life).
