It fits the X-T4, GFX100S, GFX50S II, and X-H2S mirrorless cameras. The NP-W235 powers the sensor, autofocus system, image stabilisation, and video processing across all four bodies.\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 form factor and the same 7.4V rail. The BMS connector pinout and physical housing are identical across the range, so one spare covers the full lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the X-T4 body. The BMS accepted the cell after one full charge via the in-camera USB-C circuit, reporting capacity correctly on the battery indicator.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new cell:\u003c\/strong\u003e\n    Complete one full charge cycle through the camera body or OEM charger before shooting. The X-T4's BMS maps battery-remaining percentage against the cell's discharge curve — skipping this step causes the indicator to read inaccurately until the cycle completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy sustained 4K recording drains the NP-W235 faster than photo shooting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDuring 4K video on the X-T4, the sensor, image processor, in-body stabilisation, and autofocus all draw current simultaneously. That combined load is substantially higher than single-shot still photography. The BMS monitors cell temperature under this sustained draw — if the cell runs hot, it throttles output before the percentage indicator drops to zero. This is normal behaviour, not a fault with the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or reading 0% then recovering on the X-T4\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's indicator threshold map doesn't yet match the new cell's discharge curve. The X-T4 builds that map during the first full charge-discharge cycle. Until then, voltage readings near the lower end of the curve can fall between calibration points, causing the display to jump. Run one complete cycle — charge to full, shoot until the camera shuts off — and the percentage readout stabilises. After cycling, the cell should hold a resting voltage of approximately 8.2V at full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333617975386,"sku":"BWCS-NP235MC-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333618008154,"sku":"BWCS-NP235MC-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333618040922,"sku":"BWCS-NP235MC-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP235MC-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/fujifilm-x-t4-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
