It fits directly in place of the original cell when the factory battery no longer holds a charge or fails to power the handset. Voltage and capacity match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCP-6000 cell compatibility:\u003c\/strong\u003e\n    The SCP-6000 uses a single-cell 3.7V Li-ion pack with a low-current BMS suited to a feature-phone load profile — low modem draw, no fast-charge protocol. This replacement matches that voltage rail and connector, so the phone's charge IC accepts the cell without handshake errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the cell through a full charge and discharge sequence, confirming BMS cutoff activated correctly at both the low-voltage floor and the high-voltage ceiling. The charge IC accepted the cell without flagging an error state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, run one complete discharge from 100% down to automatic shutoff, then charge uninterrupted to full. The SCP-6000's fuel gauge IC calibrates its coulomb counter against the actual cell discharge curve during this cycle — skipping it causes the percentage readout to drift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SCP-6000 reports the wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the SCP-6000 stores a discharge curve mapped to the original cell's internal resistance and capacity. A new cell has different impedance characteristics, so the IC's stored curve no longer matches reality. The percentage display drifts — often reading high early and dropping sharply near the end. One full uninterrupted discharge-to-shutoff followed by a full charge resets the coulomb counter against the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the phone's minimum operating threshold under load — even though the displayed percentage suggests charge remains. The fuel gauge IC is still reading against an old or uncalibrated curve, so the reported percentage doesn't match actual cell voltage. Under screen-on or call load, voltage sags past the cutoff point before the display reaches 0%. Run one full calibration cycle first; if shutdowns persist, check that the replacement cell terminals are fully seated and making clean contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405154549850,"sku":"BWCS-SY6000SL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405154582618,"sku":"BWCS-SY6000SL-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405154615386,"sku":"BWCS-SY6000SL-3","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SY6000SL-big.webp?v=1779370298","url":"https:\/\/batteryweb.com\/products\/sanyo-scp-6000-replacement-battery-37v-650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
