It replaces OEM part numbers 29518, 38403, 46607, 52030, C8872A, and EI-D-LI1. The battery matches the original connector, cell voltage, and BMS profile of the S3R's power system.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFinecam S3R compatibility:\u003c\/strong\u003e\n    The S3R uses a single 7.4V Li-ion cell pack with a two-wire BMS handshake. All listed OEM part numbers share the same connector pinout and voltage rail, so this replacement communicates correctly with the camera's charge controller without triggering a \"battery error\" flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the S3R's charge and discharge circuit, confirmed BMS cutoff at the correct low-voltage threshold, and verified the charge controller accepted the pack without error flags at both cold start and mid-session reinsertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session initialisation:\u003c\/strong\u003e\n    After fitting this battery, let the camera run a full charge cycle from the OEM charger before your first shoot. The S3R's fuel gauge recalibrates its percentage display to the new cell's charge curve during that first cycle — skipping it causes the indicator to drop inaccurately in the first session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Finecam S3R shows a battery error immediately after inserting a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S3R checks BMS communication at power-on before displaying the live view. If the replacement pack has been in storage, its cell voltage may have dropped below the camera's minimum recognition threshold — typically around 6.0V on a 7.4V nominal pack. The camera interprets a silent or low-voltage BMS response as a fault and throws an error rather than powering on normally. Connect the pack to the OEM charger for 15–20 minutes before reinserting — this pulls the cell voltage above the BMS wake threshold and restores normal communication.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during continuous shooting bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring burst shooting, the S3R drives the image sensor, processor, and flash circuit simultaneously, causing short but sharp current spikes. These spikes create a momentary voltage sag at the battery terminals, which the camera's percentage indicator reads as a sudden capacity drop. Once the burst ends and current draw returns to idle, voltage recovers and the percentage jumps back up. This is a display calibration artefact — run one full charge-discharge cycle through the camera and the indicator will track the cell's actual state curve accurately at 4.2V full and 6.0V cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360795623514,"sku":"BWCS-LI1SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360795656282,"sku":"BWCS-LI1SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360795689050,"sku":"BWCS-LI1SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LI1SL-1.webp?v=1778616259","url":"https:\/\/batteryweb.com\/products\/kyocera-finecam-s3r-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
