Minox 35 — Battery Adapter, Spare Parts & Accessories

The Minox 35 is one of the most compact 35mm cameras ever made. Many models today fail due to outdated mercury batteries or missing parts. Here you’ll find everything to get your Minox 35 working again — from battery adapters to replacement covers and filter adapters.

Which Adapter Fits My Minox 35?

Two Battery Compartments, Two Adapters

The Minox 35 comes in two generations with different battery compartments. The key difference: which battery your model expects.

  • PX27 (5.6V) — Minox 35 GT, GL, EL, PE, EC, LX, TLX → our PX27 adapter with 4x SR44
  • PX28 (6V) — Minox 35 MB, ML, MDC → our PX28 adapter with 4x LR44

Attention: The original PX27 and PX28 mercury batteries have not been available for years. Without an adapter, modern alternatives deliver the wrong voltage — this leads to incorrect exposures. Our adapters correct the voltage to the proper level.


Battery Adapters Compared

Adapter Replaces Cell type Compatible with Price
PX27 Adapter PX27 / V27PX 4x SR44 GT, GL, EL, PE, EC, LX, TLX from EUR 19.95
PX28 Adapter PX28 / 4SR44 4x LR44 MB, ML, MDC EUR 19.95
V28PX Adapter V28PX / 4SR44 4x SR44 MB (6V), MBC, ML from EUR 19.95

The two most important adapters for the Minox 35 at a glance. The PX27 covers the GT generation, the PX28 the later MB/ML models.

V28PX Multi-Adapter

The V28PX is not just a Minox adapter — it also fits Pentax 67, Mamiya RZ67, Canon AE-1, and many other classics. The Minox 35 MB/ML/MBC with 6V battery compartment works with it just the same.

Spare Parts

The battery compartment cover is the most commonly missing part on used Minox 35 cameras. Often lost or broken during battery changes — our replacement is made from durable material and fits all PX27 models.

Compatible models

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

Accessories

The Minox 35 has an unusual filter thread: 30.5mm. Standard filters don’t fit. Our filter adapter bridges the gap to common 37mm filters — UV, polarizers, close-up lenses.

Compatible models

  • Minox 35 GT
  • Minox 35 GL
  • Minox 35 EL
  • Minox 35 EC
  • Minox 35 LX
  • Minox 35 ML

Battery Refill Pack

SR44 silver oxide batteries last longer and provide more stable voltage than the cheaper LR44 alkaline cells. We recommend SR44 for all Minox 35 adapters designed for them. Four pieces are enough for a complete refill.


Things to know about the Minox 35

PX27 vs. PX28 — What’s the difference?

Both battery types are mercury batteries, banned in the EU since the 2000s. The difference lies in the voltage:

  • PX27 — 5.6 volts, used in older models (GT, GL, EL, PE, EC, LX, TLX). Our adapter stacks 4x SR44 silver oxide cells to exactly 6.2V. The camera’s internal voltage regulator compensates for the slight difference.
  • PX28 — 6 volts, used in later models (MB, ML, MDC). Here, 4x LR44 or 4x SR44 fit directly because the 6V closely matches the original voltage.

Why SR44 instead of LR44?

LR44 (alkaline) batteries are cheaper but steadily lose voltage during discharge. SR44 (silver oxide) batteries maintain nearly constant voltage until just before the end — which is crucial for the Minox 35’s light meter. Fluctuating voltage leads to fluctuating readings. For accurate exposure, choose SR44.

Lost your battery compartment cover?

The small sliding cover on the battery compartment of the Minox 35 often gets lost during battery changes. Without the cover, the battery is exposed — no contact, no function. Our replacement cover made of sturdy plastic is precisely crafted and fits securely in the frame. Fits all PX27 models (GT, GL, EL, PE, EC, LX, TLX).
