I have just bought a Yashica Mat-124 TRL. Looing in the manual, the
batteries used were either a PX-13B or EPX-B (1.3v). Knowing that
they do not use the mercury batteries anymore, what do I use? What
can I expect from using the newer batteries? I have seen the battery
issues but they seem to be mostly on the 124G. I went to the site
for the MR-9, but that seems to be just for the 124G. Does anyone
have experience with the 124 and newer batteries? Thanks for your
assistance.

I think Wein Cell makes a replacement for the PX-13B. I believe it's a silver oxide battery with a voltage regulator to simulate the mercury ones. But I must say that the meter on my 124G was pretty useless if you're shooting slides. You'd be much better of with a small meter like the Sekonic 308B in my experience.

I found the meter in my Mat 124 to be terribly unreliable, even after using a benchtop voltage regulator. I had been looking for an excuse to get handheld meter, and this was it. :-)

You'd use batteries? In a YashicaMat? Oh well, if you really want to do that, go to
CRIS cameras
and look at their battery adapters that allow you
to use modern batteries to power equipment that wants
mercury cells. Their MR-9 adapter will make a S76 battery
look like a PX-13.

Hi,
I've asked Kyocera, Germany, a few month ago. They would carry out a little modification so you can use a 1.5V cell instead of the obsolete 1.3V mercury cells. Costs about 50.- Euro.

1.3 volt mercury batteries are easily found at most stores that carry classic cameras. leon hertzson at the camera place (who has a web site) always has a good stock. i buy mine at new england photo in arlington, mass. rather than using an adapter, a bettre long term solution is to have the meter recalibrated to be accurate with the higher voltage cell.

I just bought a Yashica Mat 124G. Just where in the heck is the battery on this little beauty?
