It matches OEM part numbers KN02XL, HSTNN-IB7R, HSTNN-UB7F, and TPN-W124. It physically seats and connects the same way as the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion 11M and x360 11-ad platform fit:\u003c\/strong\u003e\n    These models share the same 7.7V two-cell architecture, identical connector pinout, and BMS handshake protocol — which is why a single cell covers the Pavilion 11M-AD000, 11M-AD013DX, x360 11-ad022tu, and 28 additional variants on the same board revision.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Pavilion x360 11-ad unit and confirmed the BMS accepted the new EEPROM data without fault codes, the charge circuit progressed through CC\/CV stages correctly, and the system reported capacity within normal range after two full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on Pavilion 11M:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until Windows triggers hibernate at its cutoff threshold, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every 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 immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Pavilion 11M reads EEPROM data from the battery's protection circuit to determine health status. When a new cell arrives, that EEPROM reflects factory defaults — not data calibrated to your system — so the BIOS flags it as degraded or unknown. This is not a fault with the cell. Run one complete discharge-to-hibernate cycle followed by a full uninterrupted charge to 100%, and the BIOS learn cycle will overwrite the stale health data. After two to three calibration cycles, the HP Battery Check utility should report normal status.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down unexpectedly 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 yet mapped the new cell's discharge curve. The OS thinks 25% remains, but the actual cell voltage has already hit the BMS low-voltage cutoff — typically around 6.0V for a 7.7V two-cell pack under combined CPU and display load. The mismatch causes an abrupt shutdown rather than a graceful hibernate. To fix this, complete two to three full discharge-to-cutoff and charge-to-100% cycles so the fuel gauge IC can recalibrate its state-of-charge model against the actual cell characteristics.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409732304986,"sku":"BWCS-HPP110NB-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409732337754,"sku":"BWCS-HPP110NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409732370522,"sku":"BWCS-HPP110NB-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPP110NB-1.webp?v=1779580542","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-11m-replacement-battery-77v-4600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
