Etone brass metal battery adapter for older film camera exposure meters mr9

1 adapter: €16 2 adapters: €24 This is an eTone PX625 / MR-9 Brass Battery Adapter, designed to allow modern button cell batteries to be used in classic vintage cameras and light meters that originally required discontinued mercury batteries (PX625 / PX13 / MR-9). Since mercury batteries are no longer produced, this adapter solves the problem by allowing the use of modern alternatives such as LR44 / SR44 or 675 Zinc-Air cells, by resizing them to fit perfectly into the original battery compartment. It is a precision CNC-machined solid brass sleeve that ensures a secure fit, stable electrical contact, and long-term reliability. The small ventilation hole also allows Zinc-Air batteries to activate properly by letting air enter the cell. Unlike plastic adapters, this brass version is durable, non-flexible, and provides excellent conductivity. 📸 Compatibility Cameras that use 1 adapter: Olympus Trip 35, Olympus OM-1, Olympus OM-1N, Canonet QL17, Canonet QL17 G-III, Canonet QL19, Canonet New 28, Minolta SRT-101, Minolta SRT-201, Minolta SRT-102, Rollei 35, Rollei 35S, Leica M5, Leica CL, Nikkormat FT, Nikkormat FTN, Nikkormat FT2.
