It fits the AS62FM945GM1, AS62FP945GM1, AS62J945PM1, AS62JM945PM1, and at least nine additional models in the same series. If your original cell has degraded or stopped holding charge, this replaces it directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAS62 series compatibility:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell configuration with the same connector pinout and BMS communication protocol. That's why one cell fits across the full AS62 lineup without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, discharge, and BMS handshake verification. The protection circuit responded correctly to over-voltage and over-current events, and the cell held within 2% of rated capacity at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery only until it hibernates, 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 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 AS62 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS on these ASmobile notebooks stores learned capacity data from the previous cell in non-volatile memory. When a new cell arrives with a different charge history, the BIOS compares it against stale figures and flags the health as poor or unknown. This is not a fault with the replacement cell — it's an EEPROM mismatch. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and resolves the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% battery shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't been calibrated against the new cell's actual discharge curve. The gauge was trained on the old cell's voltage-to-capacity profile, so it misjudges where the voltage cliff is. Under combined CPU and display load, the cell hits the BMS cutoff voltage before the OS expects it. Run two full discharge-to-hibernate and full-charge cycles — by the third cycle the fuel gauge tracks the real cutoff at or below 10%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410852053082,"sku":"BWCS-AUF3NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410852085850,"sku":"BWCS-AUF3NB-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410852118618,"sku":"BWCS-AUF3NB-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUF3NB-1.webp?v=1779581357","url":"https:\/\/batteryweb.com\/products\/asmobile-as62fm945gm1-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
