Since these batteries (PX640) are no longer available, this adapter offers a functional solution. It is precisely made and adapts a common 675 zinc-air cell to the PX640 format.\u003c\/p\u003e\n\u003cp\u003eUnlike alkaline batteries, whose voltage steadily drops and is initially too high (1.5V), zinc-air cells maintain a constant voltage of about 1.4V. This ensures correct exposure values without recalibrating the camera. The adapter itself is purely mechanical and passes the current directly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant note:\u003c\/strong\u003e NEVER charge in the original charger.
