All you like to ask or tell about the famous Rollei 35 : the orginal Rollei 35 made in Germany , the 35 series made in Singapore and the German Classic
i PURCHASED A WEIN CELL MRB625. IT DID NOT FIT IN THE BATTERY HOLE. IT WAS TOO LARGE. I HAVE A ROLLEI 35 MADE IN GERMANY & A SECOND ROLLEI 35 MADE IN SINGAPORE. SAME THING. I PROBABLY SHOULD HAVE READ THE WHOLE FORUM FIRST.
If your "WEIN CELL MRB625" doesn't fit into your "Rollei 35 S", the battery compartment's lid is in its very place (or you got cheated and purchased a fake camera or fake battery ;-).
