It fits the N82, N82E, N82EI, N82J, and related variants that share the A32-N82 or A42-N82 part number. If the original cell is no longer holding a charge or the laptop dies mid-session, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN82 series compatibility:\u003c\/strong\u003e\n    The N82, N82E, N82EI, and N82J all run the same 11.1V battery rail and use an identical connector and BMS handshake. A single cell covers the range without modification.\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 N82 hardware. The BMS communicated correctly with the BIOS, accepted a full charge, and held voltage within spec across the discharge curve without triggering false low-battery cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the N82:\u003c\/strong\u003e\n    After fitting this cell, run the laptop down to hibernate cutoff, then charge uninterrupted to 100% before using it again. The N82's BIOS uses a battery learn cycle to map the new cell — skipping this step causes the fuel gauge IC to misreport capacity for several weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N82 BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe N82 BIOS reads health data from the battery's EEPROM, which stores cycle count, rated capacity, and charge history from the previous cell. When a new cell is installed, that EEPROM data starts at factory defaults — the BIOS interprets the mismatch as a degraded or unknown cell and throws a health warning. This is not a fault with the replacement. Running one full discharge-to-hibernate then an uninterrupted charge to 100% triggers the BIOS learn cycle, which overwrites the stale EEPROM read and clears the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eN82 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the old or degraded cell can no longer sustain voltage under combined CPU and display load — the cell hits a voltage cliff while the fuel gauge still reads a comfortable percentage. The OS fuel gauge IC calibrates against charge data, not live voltage, so it lags behind actual cell state. A replacement cell with full capacity eliminates the cliff. After fitting, complete two full discharge-to-hibernate and full-charge cycles so the fuel gauge IC re-maps to the new cell's actual voltage curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409806164058,"sku":"BWCS-AUN82HB-1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409806196826,"sku":"BWCS-AUN82HB-2","price":142.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409806229594,"sku":"BWCS-AUN82HB-3","price":155.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUN82HB-1.webp?v=1779580971","url":"https:\/\/batteryweb.com\/products\/asus-n82-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
