Part number HB3S1. It fits the slim 10-inch tablet chassis and connects to the original BMS board without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMediaPad S10 series fit:\u003c\/strong\u003e\n    The S10, S101U, S101L, and 10FHD all share the HB3S1 form factor — same connector pinout, same voltage rail at 3.7V nominal, and the same BMS handshake protocol. One cell covers the full range.\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 full-draw discharge on a MediaPad 10FHD. The BMS accepted the cell without fault flags, held charge termination correctly at 4.2V, and showed no thermal anomalies during the high-current draw phase.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration for the MediaPad fuel gauge:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to automatic shutdown, then charge uninterrupted to 100%. This forces the tablet's fuel gauge IC to re-map against the new cell's actual capacity curve and clears the inaccurate percentage readings that appear in the first few cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MediaPad 10FHD reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MediaPad stores battery health data in EEPROM on the BMS. When you fit a new cell, the EEPROM still holds the degradation profile from the old one. The OS reads that stored data first — not the actual cell voltage — so it flags the battery as poor or unknown before any real measurement has occurred. Running two full charge-discharge calibration cycles overwrites the stale EEPROM values and brings the health indicator back to normal. No firmware update or factory reset is needed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet showing 23% then cutting to black mid-use after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a defective cell. Under combined Wi-Fi, display, and processor load, the cell voltage drops faster than the fuel gauge can recalculate. The tablet's low-voltage protection triggers a hard cutoff before the displayed percentage reaches zero. The fix is a full calibration cycle: discharge the tablet to automatic hibernate shutdown, then charge to 100% without interruption. After two cycles, the fuel gauge IC has enough data to accurately track voltage sag under load and the premature shutdowns stop. Target charge termination voltage is 4.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409785782362,"sku":"BWCS-HUS100SL-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409785815130,"sku":"BWCS-HUS100SL-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409785847898,"sku":"BWCS-HUS100SL-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUS100SL-1.webp?v=1779580888","url":"https:\/\/batteryweb.com\/products\/huawei-mediaapad-10fhd-replacement-battery-37v-6400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
