Hi, I have a question today.
I own a Rodenstock Apo-Ronar 9/360 in a beautiful Compur Electronic 3 shutter on an original Linhof board. A wonderful lens, I like it very much.
For the shutter you need a battery. I found out what possibilities are available (button cells, dedicated batteries, external power source, solar cells from China, which you glue on a lens cap with a hot glue gun etc.). I purchased two batteries in the USA with exactly the right dimensions to replace the original battery: an Exell Alkaline Battery A133 that replaces the original PX21 - everything worked wonderfully!
But today, after three months, I saw that the battery bulges at one pole. Apparently it is about to explode. Of course, the battery is dead and the wonderful shutter only releases in its shortest time and T.
Why is that? I have the same type of battery in a Compur Electronic 1 with a 210 Symmar. I love these shutters. They are so precise, they have the modern time scale and they are also ergonomically great. On the Symmar or Compur Electronic 1, the battery from the same manufacturer that I bought at the same time is still ok. I have perhaps only released both shutters 100 times so far.
Is it possible that there is an electronic defect in Compur Electronic 3? But why does this shutter work with the battery of Compur Electronic 1 then?
