Like many Leica users I have ended up with a Leicameter exposure meter and of course the problem of suitable batteries rears its ugly head.

Eventually I discovered that the "ideal" replacement was the Weincell. Howevwe I have had mixed results. The first one I used was perfect, no problem. However a subsequent one used in another meter (an MR4) refused to give a battery ok indication. After fiddling with the meter contacts over a few days I could not get a reliable indication that the battery was ok and the meter gave inaccurate exposure readings. I put the meter (with battery) away and forgot about it for a few weeks. Recently I retrieved the meter from its hiding place, tried it out and all works well! Battery indicator reports battery ok and meter readings accurate. Do other folk have good/bad experiences with these batteries?

They have worked ok for me with a Pentax Spotmatic ll. That was several years ago. I don't know what the shelf life of these batteries is.
Just a thought. After exposing a Wein cell to air, it needs some time to come to life. In a very dry environment 24 hours is reasonable. Normally 30 minutes is more than enough.
