Two-Pack 2040mAh Camera Batteries

This twin pack supplies two lithium-ion cells rated at 2040 mAh and 7.2 V each, giving 14.7 Wh per unit. They are built as direct replacements for the Fujifilm NP-W235 and work with the BC-W235 charger. The bundle suits photographers who need spare power for long shooting days.

Broad Camera Compatibility

The batteries fit Fujifilm X-T4, X-T5, X-H2, X-H2S and X-S20 mirrorless bodies, plus the GFX 100S and GFX 50S II medium-format models. They are not compatible with the GFX 100 or the original GFX 50S. Using the original BC-W235 charger keeps charging behaviour identical to the factory cells.

Safety-Certified Construction

Each cell meets UL 1642 and CE standards and includes over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits. The lithium-ion chemistry delivers stable voltage through the discharge cycle. The compact 3 by 2 by 2 inch form factor slots into the camera battery compartment without modification.

Questions about this item

How many times can each 2040mAh NP-W235 cell be recharged before capacity drops noticeably?

The lithium-ion cells meet UL 1642 and CE standards and include over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits that help extend cycle life.

What stops the batteries first during continuous shooting or 4K video — heat, voltage sag, or the 14.7 Wh capacity limit?

The 14.7 Wh capacity is the hard limit; once the 2040 mAh at 7.2 V is depleted the camera shuts down.

Do the NP-W235 packs get hot or make the charger fan spin loudly when left on the BC-W235 all day?

Built-in over-heating protection prevents excessive temperature rise, and the cells are certified to UL 1642 and CE safety standards for stable all-day operation.
