solution for PX625 ???

[michel_vandeput]

Dear Leica friends,

Did you read this

It could be a solution for our Leicaflex, leicameter, Leica CL ...

Did you test it?

Best regards from Belgium

WeinCell makes a new replacement battery for the PX625 mercury. It's the MRB625 battery. See http://www.weincell.com. Adorama sells them for around 5 bucks.

 

I use them in my OM-1n and M5!

I've had bad expierences with the Wein cells. As soon as you peel open the sealing tape on the Wein cels, they star to dischage. I've NEVER gotten the 6 month life out of them as claimed (and the cell causes at least a 1 stop error). More like two weeks (in a Spotmactic).

 

There are only two real solutions.

 

1. Find real mercury cells. They are getting VERY hard to find but they are still out there. Expect toi pay $8 each or so.

 

2. Have the meter rebuilt with new resistor arrays to match the 1.5v batteries. I just had my wife's OM-1 meter rebuilt this way by Camtech. Simply "adjusting" the meter to use 1.5v does NOT work.

CRIS makes silveroxide adapter for px 625

It reduces 1.55 v silver oxide cell to 1.35 v

Thanks Martin, I had one battery left for my SLII, I ordered one of

the reducers. EXCELLENT !!!!!!

Most cameras and meters do not require replacing the resistors, as they are adjustable enough to be converted to 1.5v---however, it must be done by someone who knows what they're doing. Simply resetting the ISO based on a test reading is not enough, because the response is not linear (the discrepancy differs according to the light level). I don't know anything about Olypmuses but I have a very hard time believing that they require resistor replacement while all the others I've encountered do not.

 

That said, the CRIS adaptor is a fine solution for most cases. Once the camera needs a CLA anyway it's cheaper to have it recalibrated and then use the sizing washer from a Wein Cell and fit an MS76 inside it.

I'm using a CRIS adapter in a Luna-Pro meter and it seems to work just fine,

FWIW.

Michel,

 

I´ve been using the C.R.I.S. adapter (www.criscam.com) in a Rollei 35S for a couple of years and it works just fine.

Somewhere (maybe Classic Camera Repair Forum) I have seen a suggestion to use 675 zinc/air hearing aid batteries (@ about $1.00 each) as a

substitute with a short length of 18 ga. insulated wire wrapped around

to center the battery. Also have seen a suggestion to only expose

some of the air holes (in cameras which need them for meters only)

in zinc/air cells to prolong the battery life.

These folks have aPX625 Silver cell available. May be a better choice for some equipment.
