It fits the Mini CQ10-800LA LTNA, Mini CQ10-811LA LTNA, Mini CQ10-600LA, and over 20 additional CQ10 variants sharing the same connector and BMS handshake. Cross-reference OEM part numbers 614873-001, HSTNN-IB1Y, or 629835-001 to confirm your exact unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCQ10 series compatibility:\u003c\/strong\u003e\n    These models share a common 10.8V three-cell Li-ion configuration, identical 630-series and HSTNN connector pinout, and the same BMS authentication protocol — which is why one cell works across all listed variants without firmware conflicts.\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 CQ10 unit, confirmed BMS communication across the SMBus data lines, and verified the charge controller accepted the cell without triggering a protection fault or authentication error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this cell, run the netbook on battery until it hibernates at low-voltage cutoff, then charge uninterrupted to 100% before unplugging. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on CQ10 units.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCQ10 shutting down at 20–30% remaining after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the BIOS fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell has different impedance characteristics, so the voltage-to-capacity mapping is wrong until it learns the new cell. Under combined CPU and display load, voltage sags faster than the uncalibrated gauge expects, triggering an emergency cutoff before the displayed percentage reaches zero. One full discharge-to-hibernate cycle followed by a complete uninterrupted charge corrects the mapping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting wrong Wh rating in system information after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure shown in BIOS or Windows battery report is read from EEPROM data embedded in the battery pack, not calculated live from the new cell's chemistry. If the replacement cell's EEPROM reports a rated figure that differs from the original, Windows will display a mismatched design capacity — this does not reflect actual stored energy. The fuel gauge will recalibrate the usable capacity over two to three full charge-discharge cycles. After calibration, check the full-charge capacity value in a battery reporting tool — it should read close to 47.52Wh.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409809965146,"sku":"BWCS-HQC10NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409809997914,"sku":"BWCS-HQC10NB-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409810030682,"sku":"BWCS-HQC10NB-3","price":121.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HQC10NB-1.webp?v=1779581043","url":"https:\/\/batteryweb.com\/products\/compaq-mini-cq10-800la-ltna-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
