It replaces the original HB6081V1ECW-22A cell when the stock battery has degraded, swells, or no longer holds a charge. The connector and BMS handshake match the original hardware.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMagicBook Pro 4600H \/ HLYL-WFQ9 \/ MagicBook Pro i fitment:\u003c\/strong\u003e\n    These three models share the same 7.64V battery rail, identical ZIF connector pinout, and the same BMS communication protocol — so one cell covers all three without any adapter or firmware difference.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the MagicBook Pro platform. The BMS accepted the new cell without triggering a protection cutoff, and the fuel gauge IC responded correctly once a calibration cycle was completed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the MagicBook Pro:\u003c\/strong\u003e\n    After fitting the new cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears 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 battery health as poor immediately after swapping the cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MagicBook Pro's BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell on first boot. A fresh cell with no cycle history triggers a mismatch flag, which shows as \"poor\" or \"unknown\" health — not a fault with the replacement. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100%. The BIOS battery learn cycle will rewrite the health register once the full cycle completes. After that single cycle the health status reports correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a faulty cell. Under full CPU and display load, the MagicBook Pro draws enough current to pull the cell voltage below the BMS cutoff threshold before the fuel gauge reaches 0%. The gauge IC was calibrated against the old cell's discharge curve, so it reads 20–30% when the actual usable charge is already gone. Two full discharge-to-hibernate and recharge cycles recalibrate the fuel gauge IC against the new cell's curve. After calibration, the shutdown point drops back to single-digit percentages where it belongs.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409539596378,"sku":"BWCS-HNR900NB-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409539629146,"sku":"BWCS-HNR900NB-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409539661914,"sku":"BWCS-HNR900NB-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HNR900NB-1.webp?v=1779579965","url":"https:\/\/batteryweb.com\/products\/honor-magicbook-pro-4600h-replacement-battery-764v-7300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
