It matches the original cell's voltage rail, physical footprint (47.20 × 36.20 × 15.50mm), and BMS communication protocol. Capacity is rated at 1230mAh (9.1Wh), identical to the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFinePix HS and X-Pro platform fit:\u003c\/strong\u003e\n    The HS30EXR, HS33EXR, and X-Pro1 share the same battery bay geometry and 7.4V power rail. All three bodies use the same BMS handshake, so one cell covers the full range without modification or adapter.\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 an HS30EXR body and an X-Pro1. The BMS accepted the cell without error flags, charge termination triggered correctly at 8.4V, and protection circuitry responded to simulated overdischarge at the expected threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the HS30EXR:\u003c\/strong\u003e\n    Insert the new cell and charge it fully inside the camera body or OEM charger before your first shoot. The HS30EXR's battery-remaining indicator calibrates its display mapping during this first cycle — skipping it often causes the percentage to drop erratically in the first few sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the HS30EXR battery indicator reads incorrectly after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HS30EXR maps its battery percentage display against a discharge curve learned from the previous cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The camera reads a mid-range voltage and maps it to the wrong percentage point, making the indicator appear to jump or collapse suddenly. Running one full charge-discharge cycle inside the camera body allows the firmware to re-anchor its voltage threshold table to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShot count dropping sharply when shooting with flash or continuous AF\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe rated shot count for NP-W126S-powered bodies is measured under controlled CIPA conditions — single shot, flash every other frame, no video. On the HS30EXR, enabling continuous autofocus, shooting bursts, or using the built-in flash on every shot stacks current draws that far exceed the CIPA baseline. The capacitor recharge current for flash alone can pull well above the camera's idle draw. If shot count feels short, check whether flash mode is set to Auto rather than forced-off, and confirm AF is set to single-shot rather than continuous tracking.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333557878874,"sku":"BWCS-FNP126MC-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333557911642,"sku":"BWCS-FNP126MC-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333557944410,"sku":"BWCS-FNP126MC-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNP126MC-1.webp?v=1778212934","url":"https:\/\/batteryweb.com\/products\/fujifilm-finepix-hs30exr-replacement-battery-74v-1230mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
