It fits models TB-X6C6F, TB-X6C6X, and Tab K10. OEM part number L20D1P32 confirms the correct cell format and connector for these boards.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTB-X6C6F, TB-X6C6X, and Tab K10 compatibility:\u003c\/strong\u003e\n    These three models share the same mainboard charging circuit, connector pinout, and BMS handshake protocol — so a single L20D1P32 cell works across all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a TB-X6C6F unit. The BMS communicated correctly with the charge IC, accepted a full charge without thermal fault, and reported state-of-charge to the OS without error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to map its thresholds against the new cell and clears the percentage drift that shows up on fresh installations.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet shutting down at 15–25% after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores calibration data from the old cell. When a new cell goes in, the IC's stored voltage-to-capacity curve no longer matches the real discharge profile of the replacement. Under combined display and WiFi load, the voltage drops sharply at the low end — faster than the stale curve predicts. The IC reads that as zero capacity and cuts power. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% recalibrates the curve against the new cell and stops the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not resuming after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tab M10 Plus uses USB-PD negotiation to step up charge voltage from the adapter. On the first cycle with a new cell, the charge IC runs a conditioning pass at standard voltage before it accepts the higher PD profile. This looks like fast charge is broken, but it is not a fault. Complete one full charge cycle from a low state using the original Lenovo adapter. After that cycle finishes, fast charging resumes at the negotiated voltage on subsequent charges.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43306859692122,"sku":"BWCS-LVX660SL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43306859724890,"sku":"BWCS-LVX660SL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43306859757658,"sku":"BWCS-LVX660SL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVX660SL_1.webp?v=1777768792","url":"https:\/\/batteryweb.com\/products\/lenovo-tb-x6c6f-replacement-battery-386v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
