Four-Pack Li-Ion Replacement

The Kastar four-pack supplies four NP-W235 lithium-ion batteries rated at 7.2V and 2040mAh each. They replace the Fujifilm NP-W235 and work with the BC-W235 charger. The set suits photographers who need multiple spares for long shooting days.

Upgrade from single OEM units

A single factory battery often forces a change mid-session; four cells let you rotate through a full day without recharging. The jump is worth it when you shoot events, travel or video where power outlets are scarce and downtime costs shots.

Sustained load behaviour

Each cell delivers 14.7 Wh and includes protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The safety circuits meet UL1642 and CE standards, so voltage stays stable through continuous capture instead of sagging after a burst.

Questions about this item

What camera models accept the NP-W235 2040mAh 7.2V battery?

This pack fits Fujifilm X-T4, X-T5, X-H2, X-H2S, GFX 100S and GFX 50S II cameras. It does not fit the GFX 100 or GFX 50S models.

How do I install the batteries in the Fujifilm BC-W235 charger?

Align each battery's contacts with the charger slots, press down until it clicks, then connect the charger to power. The step often missed is waiting for the charge indicator to turn solid before removing them.

When should I replace these Li-Ion cells?

Replace them when they no longer hold a full 14.7 Wh charge or when run time drops noticeably below the rated 2040mAh capacity. The built-in protection circuit meets UL1642 and CE standards.
