It fits via the OEM-spec connector and communicates with the HP BIOS over the standard SMBus interface. Capacity figures come from the product data, not estimated web figures.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion m6 and Envy dv4 platform fit:\u003c\/strong\u003e\n    Both lines share a common 11.1V three-cell-series architecture and the same physical bay dimensions. The BMS in this pack is keyed to respond to HP's BIOS polling on the SMBus, so the firmware handshake completes without a driver workaround.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We seated this pack in an m6-1045dx and an Envy dv4-5260nr, confirmed SMBus communication established within 30 seconds, and verified the BMS reported state-of-charge correctly to the HP power manager without triggering a charge-fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff on battery alone, then charge uninterrupted to 100% before unplugging. This forces the fuel gauge IC to recalibrate against the new cell chemistry and clears the inaccurate health warning the BIOS logs 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 this pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eHP's BIOS reads health data from the battery's EEPROM on first contact. The old cell writes cycle count and degradation flags to that register, and the BIOS caches that data even after a swap. A new pack ships with a fresh EEPROM, but the BIOS log still holds the previous battery's status until a full learn cycle forces a rewrite. Run one full discharge to hibernate, then a full uninterrupted charge to 100%. After that cycle completes, recheck the battery report in HP Support Assistant — the health flag clears once the BIOS has written a new baseline from the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff event, not a capacity fault. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track, and the pack hits the BMS low-voltage cutoff while the OS still shows 20–30% remaining. The fuel gauge IC has not yet mapped the new cell's discharge curve, so its percentage estimate lags reality. Run two full discharge-to-hibernate and full charge cycles back to back — after the second cycle, the fuel gauge recalibrates the curve and the shutdown threshold aligns with the displayed percentage. Target cell voltage at cutoff is 9.0V across the pack (3.0V per cell).\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410738741338,"sku":"BWCS-HDV6HB-1","price":115.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410738774106,"sku":"BWCS-HDV6HB-2","price":131.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410738806874,"sku":"BWCS-HDV6HB-3","price":145.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV6HB-1.webp?v=1779580887","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-m6-1000-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
