It fits the Sanyo SCP-5300 feature phone directly, matching the original battery's footprint, connector, and voltage rail. Capacity is 1000mAh — identical to the factory spec listed for this handset.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCP-5300 platform fit:\u003c\/strong\u003e\n    The SCP-5300 uses a single-cell Li-ion pack at 3.7V nominal. This replacement matches that voltage rail and the BMS handshake the phone's charge IC expects. No modification needed — the connector seats and the charge circuit accepts the cell as original.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the SCP-07LBPL through charge and discharge cycles on the bench. The BMS engaged charge termination correctly at 4.2V and held cutoff at the low-voltage threshold without tripping into lockout under normal load conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100% before normal use. The SCP-5300's fuel gauge IC is calibrated to the old cell's discharge curve — one full cycle lets it remap against the new cell and report accurate percentages.\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-5300 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SCP-5300 uses a fuel gauge IC that tracks charge state by learning the discharge curve of the installed cell over time. When a new cell goes in, the IC is still mapped to the old cell's curve — often a degraded one with a compressed voltage range. The mismatch causes the display to read 80% when the actual state of charge is closer to 50%, or drop suddenly near what it thinks is empty. One full uninterrupted discharge-charge cycle forces the IC to relearn the new cell's actual voltage-to-capacity curve and corrects the readout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff failure. Under screen-on or radio load, the cell's terminal voltage sags faster than the fuel gauge IC anticipates, crossing the low-voltage cutoff threshold before the displayed percentage reaches zero. On a fresh cell this is most common before the first full calibration cycle — the IC's empty-point estimate is set too high based on the old degraded cell. Complete one full discharge to shutdown and a full charge to 100%. If the shutdowns continue past two full cycles, check that the battery contacts on the phone are clean and making full contact, as high contact resistance amplifies voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405155500122,"sku":"BWCS-SY5300SL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405155532890,"sku":"BWCS-SY5300SL-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405155565658,"sku":"BWCS-SY5300SL-3","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SY5300SL-big.webp?v=1779370315","url":"https:\/\/batteryweb.com\/products\/sanyo-scp-5300-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
