It restores power to calling, messaging, and app functions when the original cell has degraded or failed to hold charge. Dimensions are 53.00 × 33.90 × 5.70mm — confirm these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eClassic, Hit, and Simple compatibility:\u003c\/strong\u003e\n    These three Skylink models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Skylink platform. The BMS accepted charge correctly, protection circuits triggered at expected voltage limits, and the connector seated without play.\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\"\u003eWhy the Skylink Classic reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a discharge curve built from the old cell's behaviour. When a new cell goes in, the IC has no reference data for how voltage drops under load across the new cell's capacity range. The percentage readout drifts because the IC is mapping measured voltage against a curve that no longer applies. One full discharge down to auto-shutoff followed by a full uninterrupted charge resets the coulomb counter and re-anchors the gauge to the new cell.\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 fuel gauge IC hasn't yet recalibrated and the cell voltage drops sharply under modem or screen load — a voltage cliff the old curve didn't predict. The phone's low-voltage protection trips before the displayed percentage reaches zero. It is not a faulty cell. Run one full cycle without interruption and let the gauge track the actual discharge curve. After calibration, the shutoff point should align with a reported level below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404286754906,"sku":"BWCS-DEP215SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404286787674,"sku":"BWCS-DEP215SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404286820442,"sku":"BWCS-DEP215SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP215SL-1.webp?v=1779369550","url":"https:\/\/batteryweb.com\/products\/skylink-classic-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
