It replaces OEM part numbers 312-0867, 312-0931, 312-0935, F144M, H766N, J590M, J658N, M457P, and K711N. Physical dimensions are 203.71 × 46.97 × 36.19mm — verify against your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMini 10 series compatibility:\u003c\/strong\u003e\n    The Mini 10, Mini 1011, and Mini 10v all run the same 11.1V three-cell architecture with an identical connector pinout and BMS handshake protocol. That shared platform is why 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 ran this cell through charge, discharge, and BMS communication checks on a Mini 10 unit. The BMS handshake completed without fault codes, and charge acceptance held steady across three consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install calibration on the Inspiron Mini 10:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff — do not interrupt it. Then charge uninterrupted to 100%. This single learn cycle resets the BIOS fuel gauge against the new cell chemistry and clears the false \"poor health\" flag that almost always appears after a cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health after swapping the Mini 10 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mini 10 BIOS stores learned capacity data in EEPROM from the previous cell. When a new cell goes in, that stored data no longer matches actual cell behaviour, so the BIOS flags health as poor or unknown. This is a firmware state, not a defect in the replacement cell. Running one complete discharge-to-hibernate followed by an uninterrupted full charge forces the BIOS to rewrite its learned capacity values against the new chemistry. After that cycle, health status should read normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eInspiron Mini 10 shutting down at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell — its state-of-charge map still reflects the old, degraded cell's voltage curve. Under combined CPU and display load, the new cell hits a voltage profile the uncalibrated gauge misreads as near-empty, triggering an early shutdown. The fix is the same learn cycle: discharge fully to hibernate, then charge to 100% without interruption. After two to three of these cycles, the gauge recalibrates and the cutoff point moves back to the correct low-voltage threshold near 10.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410814468186,"sku":"BWCS-DEM911HB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410814500954,"sku":"BWCS-DEM911HB-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410814533722,"sku":"BWCS-DEM911HB-3","price":121.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEM911HB-1.webp?v=1779581211","url":"https:\/\/batteryweb.com\/products\/dell-inspiron-mini-10-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
