It fits the X-T4, GFX100S, GFX50S II, and X-H2S mirrorless camera bodies. Capacity matches the OEM cell — no downgrade.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX-T4, GFX100S, GFX50S II, X-H2S compatibility:\u003c\/strong\u003e\n    All four bodies share the NP-W235 footprint, contact layout, and 7.4V rail. The BMS handshake across this series reads the same authentication signal, so one cell covers the full platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the X-T4 body. The BMS accepted the cell, reported state of charge accurately after one full charge cycle, and cutoff triggered correctly at low voltage — no false shutdowns mid-shoot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on camera bodies:\u003c\/strong\u003e\n    Charge this cell once inside the camera body or OEM charger before heavy shooting. Fujifilm's BMS maps voltage thresholds to the discharge curve during that first cycle — skipping it causes the battery-remaining indicator to jump or read incorrectly in the field.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the X-T4 drains faster under sustained 4K video than stills shooting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eIn 4K video mode, the X-T4 runs the sensor, processor, in-body image stabilisation, and autofocus simultaneously — a combined draw well above what stills shooting pulls from the same cell. The NP-W235's 15.17Wh capacity is rated against CIPA stills conditions, not continuous video load. Under video, the draw can be two to three times higher, and the battery-remaining percentage drops faster than stills shooters expect. If the body gets warm during extended recording, that's normal thermal output from the processor and IBIS motor — not a fault with the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the X-T4 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's BMS hasn't yet mapped the new cell's discharge curve to its percentage thresholds. The OEM firmware uses voltage waypoints calibrated during the first charge cycle — a new cell that skipped that step reports voltage readings the BMS maps inconsistently. The fix is straightforward: run the battery down to the camera's auto-shutoff point, then charge it fully inside the camera body or with the OEM BC-W235 charger. After that single cycle, percentage display stabilises to within a few points across the full charge range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333603557466,"sku":"BWCS-NP235MU-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333603590234,"sku":"BWCS-NP235MU-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333603623002,"sku":"BWCS-NP235MU-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP235MU-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/fujifilm-x-t4-replacement-battery-74v-2050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
