Rolle 35 Classic meter with jumpy needle

[zeiter]

I got a Rollei 35 Classic back in 2005 brand new. I love it. for the last couple of years , I've been using a 1.55 silver oxide battery in one of those converters from 1.55 to 1.35 v, shaped like a PX625, where I insert the small SR43 battery. Anyway, it's been very accurate. Recently, meter needle have been jumpy, like it would be working, then shift to OFF, I mean far left, then back to middle, randomly. Could stay ON or OFF for a while, etc... I checked the battery on my tester, and it's still full. My question : with these symptoms, could it be the battery even though showing full, as I heard silver oxide is unstable voltage ( never complained about it before ), or adapter at fault, or simply the meter is dying ( hopefully not ). Thanks.

Most Rollei 35 meters that did really die, died from the escaping mercury (or maybe it was the mercury cell's potassium hydroxide ;-) of dead PX 625 cells (kreeping along the contact "dissolving" a spotwelded joint inside the camera).

Maybe cleaning all contacts will help, maybe a new cell will help.

I think I found the source of the problem. My battery cover was screwed in a crooked way, and not pushed down to the max, which might have caused a battery to loose contact possibly inside.
