It fits the Fujifilm FinePix 1700z, 2700, 2900z, and 4800 Zoom, along with twelve additional FinePix models that share the same battery compartment and connector. If your original NP-80 no longer holds a charge, this is the direct replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFinePix NP-80 platform compatibility:\u003c\/strong\u003e\n    All listed FinePix models run the same 3.7V rail with an identical physical connector and battery compartment depth. The BMS handshake on these bodies is voltage-threshold based, not chip-authenticated, so the camera reads cell state through voltage alone — no firmware pairing required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through full charge and discharge cycles on a FinePix body. The BMS accepted the cell without rejection, charge termination triggered correctly at 4.2V, and low-voltage cutoff engaged at the expected floor without tripping prematurely under flash load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on FinePix bodies:\u003c\/strong\u003e\n    Before shooting, run one complete charge cycle through the OEM charger or inside the camera body itself. FinePix cameras map their battery-remaining indicator to a learned discharge curve — skipping this step can cause the indicator to read inaccurately until the first full cycle completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling slowing down before the battery indicator drops\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe FinePix flash capacitor draws a sharp recharge current between shots. As the cell ages or sits near the lower end of its charge, internal resistance rises enough to slow that capacitor recharge — even when the battery gauge still shows bars. The camera body interprets this as normal operation and won't warn you. If flash recycling time increases noticeably mid-shoot, check cell voltage directly; anything below 3.6V under load will show this behaviour. A full recharge cycle restores normal recycling speed if the cell is otherwise healthy.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the FinePix display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe FinePix indicator maps remaining charge to a fixed voltage-threshold table calibrated to the original NP-80 discharge curve. A new cell with a slightly different discharge profile can cause the indicator to skip or jump — particularly between the 50% and 20% range where the curve diverges most. This is a display calibration issue, not a cell fault. Run two full charge-to-discharge cycles inside the camera body and the indicator will re-anchor to the new cell's actual curve. After two cycles, readings should stabilise within one bar of actual charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333575245914,"sku":"BWCS-RDB200FU-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333575278682,"sku":"BWCS-RDB200FU-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333575311450,"sku":"BWCS-RDB200FU-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RDB200FU-1.webp?v=1778212955","url":"https:\/\/batteryweb.com\/products\/fujifilm-finepix-1700z-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
