SR43 (1.55V) ×1 → approximately 1.35V
This MR-9 / H-D / PX625 / PX13 mercury battery adapter restores the original
1.35V operating voltage for vintage film cameras that originally used PX625
/ PX13 / MR‑9 / H‑D mercury batteries.
The adapter converts a 1.55V SR43 silver oxide battery (also known as SR43W,
SR43SW, 386; 301 equivalent, or 1.5V LR43) to approximately 1.35V through a
built-in voltage regulation circuit. This closely replicates the behavior of
the original mercury cell and helps maintain accurate meter readings.
