It matches the OEM part numbers TLp028B2, C2820009C2, TLp028BD, and TLp028BC. If your tablet no longer holds a charge or won't power on, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTab 2 and Xtreme 2 compatibility:\u003c\/strong\u003e\n    These four models share the same 3.7V cell format, connector pinout, and BMS handshake. The fuel gauge IC communicates over the same bus across all variants, so one part number covers the full family.\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 a KURIO tablet board. The BMS accepted the new cell without fault codes, and the charge IC stepped through its standard CC\/CV profile without interruption.\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 recalibrate against the new cell's actual capacity curve and clears the inaccurate percentage readings that appear immediately after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the KURIO Tab 2 shuts down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe tablet's display and WiFi radio together create a combined load spike that pulls voltage down sharply. When cell voltage drops below the BMS cutoff threshold under that load, the tablet shuts off even though the fuel gauge still shows charge remaining. An aged or degraded cell has higher internal resistance, which makes the voltage sag more severe. A fresh cell with lower internal resistance holds voltage above the cutoff under the same load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or stuck after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores calibration data from the old cell — it doesn't reset automatically when you swap the battery. Until you run a full discharge-to-shutoff cycle followed by a full uninterrupted charge, the reported percentage is based on stale data. After that single cycle, the IC rewrites its calibration registers against the new cell. If the percentage is still erratic after one full cycle, check that the connector is fully seated — a partial connection causes the gauge to read floating voltage values.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425846394970,"sku":"BWCS-HUC150SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425846427738,"sku":"BWCS-HUC150SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425846460506,"sku":"BWCS-HUC150SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUC150SL-1.webp?v=1779929950","url":"https:\/\/batteryweb.com\/products\/kurio-tab-2-replacement-battery-37v-2800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
