It replaces OEM part numbers including 493529-371, HSTNN-XB80, HSTNN-OB80, and 504610-001. Fits Mini 1001, Mini 1001TU, and over 130 additional Mini variants sharing the same connector and voltage rail.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMini series platform fit:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell architecture, identical BMS handshake protocol, and the same physical connector. One cell fits all variants listed — no adapter or wiring change required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Mini 1000 unit and confirmed the BMS completed charge handshake, accepted full CC\/CV charge to 12.6V, and reported cell status correctly through the OS fuel gauge IC.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on HP Mini:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. HP Mini's BIOS battery learn cycle requires this to clear the inaccurate health warning that appears after every cell swap.\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 immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Mini BIOS reads EEPROM data embedded in the battery cell. A new cell carries factory EEPROM values that don't match the BIOS's stored charge history from the old battery. This mismatch triggers a health warning that looks like a fault but isn't. Run one complete discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — that sequence resets the learn cycle and clears the warning on most Mini units.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't been calibrated against the new cell's actual discharge curve. The IC is still referencing voltage thresholds from the depleted old cell, so it reads 20–30% but the cell voltage is already dropping below the safe cutoff under CPU and display load. Run two to three full discharge-to-charge cycles without interruption. After calibration, the gauge will track the new cell correctly and shutdowns at false-high percentages stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410864865370,"sku":"BWCS-HP1000HB-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410864898138,"sku":"BWCS-HP1000HB-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410864930906,"sku":"BWCS-HP1000HB-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HP1000HB-1.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/hp-mini-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
