PX27 Battery Adapter & Alternatives

The PX27 (also V27PX, EPX27, 4AG13, 4LR43) was a 4.5V alkaline battery used in compact cameras from the 1970s onward. Original batteries are hardly available anymore or cost a lot. Here you’ll find the right adapters depending on your camera.

Two different adapters — one battery type

The PX27 was used in various camera series with different battery compartment geometries. That’s why there are two specialized adapters instead of a universal solution:

Minox 35 series (GT, EL, GL, LX, PE, EC, TLX) → Minox-specific adapter with 4x SR44 button cells
Rollei 35 SE, 35 TE, A110 → Rollei-specific adapter with 3x LR44 button cells

Attention: The adapters are not interchangeable. The Minox adapter does not fit the Rollei and vice versa. Check which camera you have before ordering.

Adapter	For cameras	Battery type	Voltage	Price
PX27 Minox adapter	Minox 35 GT, EL, GL, LX, PE, EC, TLX	4x SR44	6.2V (regulated to 4.5V)	€19,95
PX27 Rollei adapter	Rollei 35 SE, 35 TE, A110	3x LR44	4.5V	€24,95

The best-selling PX27 replacement for the Minox 35 compact camera series. Uses 4x SR44 button cells and replaces the PX27 alkaline battery. Fits perfectly into the battery compartment of all Minox 35 models.

What’s included in the set?

The adapter comes complete with 4x SR44 button cells — you can start right away. SR44 silver oxide batteries are widely available (drugstores, watchmakers, online) and cost just a few euros per set.

Compatible with

Minox 35 GT
Minox 35 EL
Minox 35 GL
Minox 35 LX
Minox 35 PE
Minox 35 EC
Minox 35 TLX
Minox 35 PL

Specifically designed for the Rollei 35 SE and 35 TE — the only Rollei 35 models that use a PX27 battery. Also compatible with the Rollei A110 pocket camera.

Important difference: Rollei 35 is not the same as Rollei 35

The earlier Rollei 35, 35 S, 35 T, and 35 B use a PX625 battery (1.35V). Only the later models 35 SE and 35 TE were switched to PX27 (4.5V). If your Rollei 35 has an "S" or "T" (without "E"), you need a PX625 adapter instead.

What was the PX27?

The PX27 was a cylindrical 4.5V alkaline battery (dimensions: approx. 13 x 25.2 mm). It was produced from the 1960s by Eveready, Mallory, and Varta. The name varies by manufacturer: V27PX (Varta), EPX27 (Energizer), 4AG13, 4LR43, No. 27. Essentially, it’s three LR43/AG12 cells connected in series.

Why is the PX27 no longer regularly available?

Unlike the PX625 (which contained mercury and was therefore banned), the PX27 was a regular alkaline battery. It wasn’t banned — manufacturers stopped making it because demand dropped after the end of analog photography. Some suppliers still produce small batches, but at high prices (often over 10 EUR each).

Why not just insert 3x LR44 batteries loose?

3x LR44 batteries add up to 4.5V — the right voltage. But without an adapter, the fit isn’t correct: the cells wobble in the battery compartment, contact is unreliable, and corrosion can occur at the connections. The adapter holds the cells in the exact PX27 shape and ensures clean contact on both poles.
