Replacement battery for GFX 50S

This lithium-ion battery replaces the Fujifilm BC-T125 cell used in the GFX 50S medium-format camera. It is built for photographers who need a spare or a direct replacement for a depleted original pack. A fully decoded chip communicates with the camera exactly like the factory unit. The pack weighs 33.4 grams and measures 123.85 x 110.93 x 42.86 mm.

Upgrading from an exhausted original cell

When the original BC-T125 no longer holds a useful charge, this pack restores full shooting time without changing workflow. The jump is worth it as soon as the original shows reduced capacity or fails to complete a session. No firmware update or menu change is required because the decoded chip mirrors the original handshake. Overcharge, over-discharge, over-voltage and short-circuit protection are built in.

Fits the GFX 50S battery compartment

The pack slides into the existing GFX 50S battery bay and locks with the same latch mechanism. It charges in the standard Fujifilm charger that accepts 110 volt input, so no new charger is needed. Shock-absorbing foam in the retail box protects the cell during transport. Buyers who need a higher-capacity cell or a different voltage will not be served by this model.

Questions about this item

What are the exact dimensions of the 123.85 x 110.93 x 42.86 mm battery so I can confirm it fits my Fujifilm GFX 50S?

The battery measures 123.85 mm long, 110.93 mm wide and 42.86 mm thick, matching the Fujifilm BC-T125 form factor for the GFX 50S and Medium Format GFX bodies.

The listing mentions installation videos — what is the critical step people often miss when connecting the decoded chip?

Align the connector pins precisely and press firmly until the latch clicks; a loose connection prevents the fully decoded chip from communicating with the camera.

After how many full charge and discharge cycles will the lithium-ion pack reach its best performance?

The manufacturer states a new battery achieves optimal performance after 2 or 3 complete charge and discharge cycles.
