OEM part numbers covered include 5260, S104-N77000-012, S104-N77000-008, and S104-N77000-002. The cell matches the original 86.20 × 66.00 × 4.85mm footprint and connector layout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSlide 2 and Pulp Fab platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — all confirmed against OEM part cross-reference. One cell covers the full variant range listed above.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran full charge and discharge cycles on this cell and monitored BMS communication with the charge IC. The protection circuit responded correctly to cutoff thresholds, and no anomalous heat events were recorded during CC\/CV transition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Wiko Slide 2 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity defect. The Wiko Slide 2's fuel gauge IC was calibrated to the discharge curve of the original aged cell. When a new cell with a steeper voltage curve is installed, the IC misreads remaining capacity and the phone cuts power before the actual charge is depleted. Under modem or screen load, instantaneous current draw causes voltage to sag below the shutdown threshold even while the reported percentage still reads high. Run one full discharge to below 5% and a complete charge to 100% without interruption — this resets the coulomb counter against the new cell curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after sitting in storage with a depleted battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the cell discharged below approximately 2.5V during storage, the BMS enters lockout mode to prevent damage to the lithium polymer structure. The phone will show no response to the power button and may not register on a charger immediately. Connect the device to a wall charger — not a USB port — and leave it for 15–20 minutes before attempting to power on. Once the BMS detects voltage above its recovery threshold (typically around 2.9V), it will re-enable the charge path and the device will begin normal charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392029851738,"sku":"BWCS-WKS200SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392029884506,"sku":"BWCS-WKS200SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392029917274,"sku":"BWCS-WKS200SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKS200SL-1.webp?v=1779143047","url":"https:\/\/batteryweb.com\/products\/wiko-slide-2-replacement-battery-38v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
