It also fits the HP 15-CS and 17-BY series, along with over 270 additional HP notebook models sharing the same HT03XL platform. Cross-reference OEM part numbers include L11119-855, HSTNN-LB8M, and TPN-I130 through TPN-I134 before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e250 G7 \/ 255 G7 platform compatibility:\u003c\/strong\u003e\n    These models share the same three-cell Li-Polymer pack format, connector pinout, and BMS handshake protocol. The 11.55V nominal rail is dictated by the HP charging IC on this platform — swapping to a different voltage pack will trip the controller and prevent charging entirely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the full HP charge cycle on a 250 G7 unit. The BMS negotiated correctly with the EC firmware, charge current stepped down normally at the 90% threshold, and the pack reached full charge without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the 250 G7:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery only until it hibernates at low-charge cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears in HP Support Assistant 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 fitting the HT03XL\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHP's EC firmware stores historical charge data from the previous cell in EEPROM. When a new pack is installed, the BIOS compares actual charge acceptance against that stale data and flags the battery as degraded before any real measurement has occurred. This is not a fault with the replacement cell. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — this overwrites the EEPROM baseline and the health warning clears on the next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHP 250 G7 shutting down at 20–30% battery shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge maps a voltage reading to a percentage using the old cell's profile — the new cell hits a voltage cliff at a different point, so the laptop loses power well before the display reads zero. It is not a defective battery. Run two to three full discharge and charge cycles without interrupting them, and the fuel gauge IC re-learns the correct curve. After calibration, shutdown should not occur above 5% remaining.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410733858906,"sku":"BWCS-HPG250NB-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410733891674,"sku":"BWCS-HPG250NB-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410733924442,"sku":"BWCS-HPG250NB-3","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPG250NB-1.webp?v=1779580500","url":"https:\/\/batteryweb.com\/products\/hp-250-g7-replacement-battery-1155v-3550mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
