It replaces a degraded or failed original battery in these slim-body Android handsets. Voltage and connector match the original spec — no modification needed during installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSublim and Cink Slim platform compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol. Swapping between them uses identical hardware, so one cell covers the full group without voltage rail differences to account for.\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 load on the Sublim platform and confirmed the BMS accepted charge without cutoff events. Capacity was consistent with the rated 1500mAh across multiple discharge passes.\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 and run one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before the charge IC pushes high current into an uncalibrated cell — preventing erratic percentage readings from the first day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Sublim reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a learned discharge curve from the original cell. When you install a new cell, that stored curve no longer matches the new cell's actual voltage-to-capacity relationship. The OS reads voltage from the gauge IC and converts it to a percentage using the old curve — so the number shown can be significantly off. One full discharge from 100% to automatic shutdown, followed by a full charge, forces the coulomb counter to recalibrate against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot hold its voltage under the combined load of the modem radio, display, and background apps — even though the gauge IC still reads 20–30%. The cell voltage drops below the BMS cutoff threshold faster than the gauge can track. It is not a faulty cell — it is the gauge IC still running an uncalibrated curve. Run two full discharge-charge cycles without fast charging and the shutdowns will move down to the correct low-battery threshold near 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404215287898,"sku":"BWCS-WKS008SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404215320666,"sku":"BWCS-WKS008SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404215353434,"sku":"BWCS-WKS008SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKS008SL-1.webp?v=1779369426","url":"https:\/\/batteryweb.com\/products\/wiko-sublim-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
