It replaces OEM part numbers BP-800S, BP-900S, and BP-1000S. Voltage and physical footprint match the original — 68.20 × 24.85 × 6.50mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFinecam S3, S3L, and S5R compatibility:\u003c\/strong\u003e\n    These three bodies share the same battery bay dimensions, connector pinout, and BMS voltage thresholds. A single cell spec covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, rest, and discharge on compatible hardware. The BMS accepted the cell without error flags, and protection circuits triggered correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    Insert the battery and run a full charge inside the camera body or OEM charger before your first shoot. Some Kyocera BMS implementations need one full in-body charge cycle to calibrate the battery-remaining indicator accurately.\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 toward the end of a shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs a Li-ion cell approaches the lower end of its discharge curve, internal resistance rises and the current available for capacitor recharge drops. The Finecam's flash capacitor draws a sharp burst of current to recycle — that burst takes longer when the cell voltage sags below roughly 3.5V. The result is a noticeable pause between shots in flash mode, even though the battery indicator still shows charge remaining. If recycling lag appears early with a new cell, confirm the charger brought the pack to 4.2V before the shoot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or reading 100% then dropping suddenly\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Finecam maps remaining charge to a voltage-threshold table calibrated for the OEM cell's discharge curve. A replacement cell with a slightly different curve can cause the indicator to misread — showing full for longer, then stepping down sharply. This is a calibration issue in the camera's fuel gauge, not a fault in the cell itself. Running two or three full charge-to-cutoff cycles inside the camera body typically re-aligns the indicator to the new cell's actual discharge profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333866258522,"sku":"BWCS-BP800-1","price":22.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333866291290,"sku":"BWCS-BP800-2","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333866324058,"sku":"BWCS-BP800-3","price":27.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP800-1.webp?v=1778213288","url":"https:\/\/batteryweb.com\/products\/kyocera-finecam-s3-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
