Rollei 35 Batteries 
The
Rollei 35 cameras including the Rollei 35S, that have an analog meter,
(light reading needle and follow pointer needle) use the PX625, 1.35
volt battery.
This is a mercury cell which has
become illegal in many states and as I understand it is no longer
manufactured by the major battery manufacturers that supply the U.S.
There are some Zinc - air cells that were made by a couple of mfgrs.
that replace the PX625 without requiring re-calibration, assuming that
the camera is not out of calibration. However these have a short life
span.
Also CRIS in Arizona offer an adaptor which reduces the voltage of the
PX76 1.5V battery to 1.35V and helps form the shape of the original PX
625. This adaptor is about $30.-- but it allows you to use the easy to
find PX76.
Battery manufacturers now offer the alkaline PX 625 A , 1.5 volt
battery as a replacement. These batteries have a more drastic voltage
fall off curve than the zinc - air cells, but they usually last a few
months, and they are more readily available than the zinc - air cells.
However if you use the alkaline PX625 A, the meter will need to be
re-calibrated.
I can calibrate your Rollei 35 or Rollei 35S for either battery.
The Rollei 35 TE , SE and LED use a 5.6volt mercury battery which is
also now illegal in most ot the U.S. Minox makes a replacement for it
which is a plastic holder and several small button cells. You can
