Kanto Camera MR-9 Battery Adapter

The solution for the discontinued (H-D, PX13, PX625) mercury battery. The adapter is the same size as the original battery. No additional modification is required (apart from certain exceptions).

This adapter has a built in circuit to reduce the voltage of SR43(386) battery 1.55V to that of a mercury battery approx. 1.35V. So you don’t have to fiddle around and have the camera converted.

Only use the Voltage Transformation Adapter with silver oxide batteries. Alkaline batteries give poor results.
