It fits the internal battery bay and connects via the original flex cable and BMS harness. OEM part numbers covered include ER06068XL, ER06XL, HSTNN-OB3I, N59734-271, and TPN-DB1T.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG11 platform fit:\u003c\/strong\u003e\n    The Elite x360 1040 G11 and EliteBook 1040 G11 share the same battery bay dimensions, BMS handshake protocol, and 11.55V nominal voltage rail — one cell fits all three listed models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a G11 chassis and confirmed the BMS handshake completes on first boot. The EEPROM initialises correctly and the HP battery manager reads full capacity without a manual learn cycle trigger.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst cycle after install:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates at low charge, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap on G11 hardware.\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 BIOS reads health status from EEPROM data stored on the battery's BMS board. A new cell ships with fresh EEPROM values that don't yet match the laptop's learned charge history, so the BIOS flags it as degraded. This is a calibration state, not a fault. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — the BIOS learn cycle resets and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated against the new cell's actual voltage curve. Under combined CPU and display load, the cell voltage drops faster than the uncalibrated gauge predicts, and the system hits the low-voltage cutoff before the percentage reaches zero. The gauge reads a false floor. Complete two full discharge-to-hibernate cycles charging back to 100% each time — after cycle two, the fuel gauge IC maps the new cell's curve accurately and the shutdowns stop. Confirm calibration is complete when the gauge reads below 10% without a forced shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409532485722,"sku":"BWCS-HPE411NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409532518490,"sku":"BWCS-HPE411NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409532551258,"sku":"BWCS-HPE411NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE411NB-1.webp?v=1779579905","url":"https:\/\/batteryweb.com\/products\/hp-elite-x360-1040-g11-replacement-battery-1155v-5600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
