It matches the OEM part number RCB06S01 and fits directly into the SC560 battery bay. Voltage, capacity, and connector position match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSC560 fit:\u003c\/strong\u003e The SC560 uses a compact single-cell Li-ion pack at 3.7V nominal. This replacement matches the OEM discharge curve and BMS communication profile, so the phone's charge controller accepts it without flagging a fault condition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We cycled this cell through a full charge and discharge sequence. The BMS held cutoff at the correct upper and lower voltage thresholds, and the charge IC accepted the cell without triggering a protection trip.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated state — preventing erratic percentage readings from the first charge onward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SC560 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SC560's fuel gauge IC stores a learned discharge curve from the previous cell. When a new cell goes in, the IC still references that old curve, which causes the displayed percentage to drift from actual state of charge. The fix is one uninterrupted full discharge down to automatic shutdown, followed by a full charge to 100% without interruption. After that cycle, the IC recalibrates its coulomb counter against the new cell. Percentage accuracy stabilises from the second cycle onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Swisstone SC560\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops sharply under modem or display load — a voltage cliff the fuel gauge didn't predict from the old curve. The phone's power IC interprets the sudden sag as a critical low-voltage event and cuts power before the displayed percentage reaches zero. It is not a faulty cell. Run one full calibration cycle as described above — the fuel gauge IC will learn where the actual voltage cliff sits on this cell and adjust the shutdown threshold accordingly. If the shutdowns continue past the third cycle, check that the battery contacts on the SC560 chassis are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391831507034,"sku":"BWCS-SWC560SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391831539802,"sku":"BWCS-SWC560SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391831572570,"sku":"BWCS-SWC560SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SWC560SL-1.webp?v=1779142282","url":"https:\/\/batteryweb.com\/products\/swisstone-sc560-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
