Firstcall PX625 Battery 1.5v

The voltage is spot-on at 1.5v, so my trusty old meter reads perfectly without any recalibration fuss. Dropped one in and it fired up instantly, which is exactly what you want from a mercury-free replacement for these vintage cameras.

My old Canon F-1's light meter was reading dead until I popped this in—the 1.5v output is spot on for the 625A spec. It's been steady through a whole roll of shots, no voltage drop-off that I can tell.

My vintage Minolta meter came back to life with this battery—the 1.5v voltage is spot on for accurate readings. No more guessing with expired cells, and it fits snugly in the compartment.
