PX27 Battery Adapter for Rollei 35 SE, 35 TE

• Replacement for the discontinued PX27: The adapter takes the place of the no-longer-available 5.6V PX27 / V27PX mercury battery in the battery compartment.
• Powered by commonly available button cells: Instead of using old stock, you use four standard SR44 (or LR44) cells, which provide 6V in total and match the original cell’s height.
• Stable readings thanks to silver oxide: The included SR44 cells have a constant discharge curve, allowing the light meter to measure consistently.

Compatibility

Specifically tested for:

• Rollei 35 SE (not for Rollei 35 S or Classic)
• Rollei 35 TE (not for Rollei 35 T)

Not suitable for Rollei 35 LED, A110, or E110. These cameras take the battery directly in a round compartment and therefore require the cylindrical PX27 adapter. The adapter on this page is a square battery holder and does not fit in those cameras.

Scope of delivery

• Standard: 1x PX27 adapter + 4x SR44 button cells
• Complete set: Standard + 1x battery-compartment coin tool

Technical details

• Material: engineering plastic
• Color: Black
• Replacement for: PX27 / V27PX (5.6V mercury)
• Required cells: 4x SR44 or LR44 (included)

Description

Finding the right battery for your Rollei 35 SE or 35 TE is difficult because the original 5.6V PX27 mercury battery has been off the market for years. This adapter holds four commonly available SR44 button cells and brings them to the height of the old cell so the contact fits properly – together, they provide 6V.

Frequently asked questions

“Does the adapter also fit the Rollei 35 S, 35 T, or Classic?”

No. It has been tested for the Rollei 35 SE and Rollei 35 TE. Models without an E in their name have a different battery compartment.

“What about the Rollei 35 LED or the A110?”

Not those either. These two cameras take the battery directly in a round compartment; the cylindrical PX27 adapter is available for them.

“6V instead of 5.6V – will the exposure still be correct?”

Yes. The light meters in the SE/TE series are electronically regulated. The small voltage difference is negligible in practice, and the cameras handle it without any problems.

“Can I use LR44 instead of SR44?”

Yes, four SR44 or LR44 cells will fit. SR44 silver-oxide cells have a more consistent discharge curve, which is why they are included.

“Are the button cells included?”

Yes, four SR44 cells are included with every variant.
