It replaces OEM part numbers LK03XL, HSTNN-UB7I, TPN-W127, TPN-W128, and TPN-W129, among others. Install it when the original cell no longer holds charge or the OS reports degraded capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnvy 17m and ZBook 15v G5 platform fit:\u003c\/strong\u003e\n    These models share the same 11.55V three-cell battery rail, identical connector pinout, and matching BMS handshake protocol — which is why one replacement cell covers the full range from the Envy 17M-AE0XX to the ZBook 15v G5 4QH58EA.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on an Envy 17m chassis, confirmed the BMS completed its handshake without error flags, and verified the fuel gauge IC registered the cell correctly after two calibration cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the Envy 17m:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery only until it hibernates at the low-voltage cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the firmware displays 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\"\u003eWhy the Envy 17m BIOS reports poor battery health immediately after a replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Envy 17m BIOS reads health data from the battery's EEPROM — a small memory chip that stores charge cycle count, rated capacity, and manufacturer data. When a new cell arrives, that EEPROM data doesn't match the history the BIOS has accumulated from the old battery. The firmware flags this as a health warning rather than treating it as a fresh cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS learn cycle to re-calibrate against the new cell's actual data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEnvy 17m shutting down at 20–30% battery shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load, even though the OS fuel gauge still shows charge remaining. The fuel gauge IC hasn't yet mapped the new cell's discharge curve, so its percentage estimate runs ahead of real voltage. The cell hits roughly 10.0V under load and the BMS trips before the gauge reaches zero. Run two full discharge-and-charge cycles to let the fuel gauge IC learn the actual voltage-to-capacity curve for this cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409728045146,"sku":"BWCS-HPK170NB-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409728077914,"sku":"BWCS-HPK170NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409728110682,"sku":"BWCS-HPK170NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPK170NB-1.webp?v=1779580542","url":"https:\/\/batteryweb.com\/products\/hp-envy-17m-replacement-battery-1155v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
