Questions & Answers

JOSE D C : can i use this battery for the leica cl film?DANA B : I do not have that camera, but the camera wiki says that it uses a PX625 mercury battery (1.35v) -- this MRB400 is not a direct replacement. You want the Wein Cell PX625/PX13 replacement battery (1.35v).
David E : Will this battery fit my Petri-Micro Compact 35mm camera?JAMES R : I used it in my Pentax SP 500. So I have no idea if it will fix yours.
cecilia o : will this batterery fit in my fujica camera st 701?ANDREW R : This battery is a zinc-air replacement for the the old mercury RM400. The Fujica ST701 requires two of these batteries.

Non-mercury replacement for EXP625 or PX625

This battery resolved a problem of meter accuracy in my Olympus OM-1 camera. When I was using a 625A (that fits perfectly), the meter was off by two stops.

Thankful for this battery.

This was worth buying. I was able to resurrect my old Minolta 201 and it does work accurately for the light meter in the camera.

It is the real deal. Right voltage.

It works just like the originals so a couple of my Minoltas and a Nikon have accurate metering now.

Wein Batteries are My Go-to for old cameras

I love Wein batteries. I've used them in 35mm and medium format cameras of various kinds and the consistency of the voltage is great.

Wein Cell PX625 Batteries Work Great

I bought these to power the meter in an old film camera that took 1.35v mercury batteries that are no longer available. Metering is accurate with these batteries, which is not the case with 1.4v zinc air hearing aid batteries which I tried, which gave overexposed readings in good light and underexposed readings in low light. The Weins are not cheap, but they work great. Can't say how long they last since I just started using them.

Make sure these batteries fit in your camera first

These batteries arrived fast and as described. I ordered these for my 35mm camera (Konica Autoreflex T3) but I realized these don't actually fit in the camera. They're too wide for the battery compartment. As far as the actual batteries, I can't actually review them since I wasn't able to use them. I'm sure they would've worked fine though if I could've used them.

Best 1.35 V Replacement Battery for Older Cameras

This battery is the correct voltage (1.35 volts) for my Konica Auto S2 camera light meter. Most new replacement batteries are 1.5 volts. I know I am getting more accurate meter readings with 1.35 volts. My research reveals that many other older cameras can use this battery (see owners manual for correct voltage). Note: Internet research recommended waiting at least 6 hours after installing the battery before light meter begins to function. I found this to be true.

Works perfectly

Provides accurate design voltage and thus accurate metering in my Nikkormat FTn. Can't speak yet to lifetime, but these cells work exactly as they're advertised to do. Will buy again!

I found the hard to find battery

By JimBob

I have a 35mm SLR [...] Camera over 35 yrs. old that still looks and works like new, but I had just about given up on finding the correct battery for it. It has sat up the past 15 yrs. for that reason. Thank goodness you carried the correct batter with the CORRECT voltage, 1.35 instead of the 1.5's currently available. Now the camera works like it is supposed to. Thank you for carrying this battery, I will be back for more. I highly recommend this product!
