Battery cover with battery adapter for Rollei XF 35

• Replacement for the banned PX625: The XF 35 was designed for 1,35V mercury cells, which are no longer available. Zinc-air cells type 675 from the drugstore are the best available substitute.
• Holds the smaller 675 cell in place: The cover centres the battery and creates the necessary contact pressure so that it does not slide around in the oversized original compartment.
• Correct metering voltage instead of incorrect exposure: The 675 cells deliver around 1,4V, which puts them closer to PX625 levels than 1,5V alkaline batteries.

Description

If you are looking for a battery replacement for the Rollei XF 35, you will quickly run into the voltage problem: the camera was originally designed for 1,35V mercury cells of type PX625. These are no longer available. Modern 1,5V alkaline cells are too high and often lead to incorrect exposures. Zinc-air batteries of type 675 from the drugstore, on the other hand, deliver around 1,4V and therefore come closest to correct light metering.

The only problem with these cells: they are considerably smaller than the original and slide around in the battery compartment. This battery compartment cover is designed exactly for that. It centers the 675 cell and creates the contact pressure the camera needs for a reliable connection. Instead of expensive special adapters or makeshift solutions with aluminum foil: cover on, battery in, start shooting.

Frequently asked questions

Does this part replace only the cover or the adapter as well? Both. The cover is also the adapter: it holds a zinc-air cell of type 675 and closes the battery compartment of your Rollei XF 35. So you don't need a second part.

Which batteries fit and how many are included? Zinc-air type 675 with 1,4V. Six are included, which will last you quite a while. You can get more as hearing aid batteries at any pharmacy or drugstore.

Why zinc-air and not a regular button cell? Zinc-air keeps its voltage almost constant over its entire service life, much like the original mercury cell. Alkaline starts higher and drops steadily, which throws off the light meter of the XF 35.
