It fits the N46, N46V, N46VJ, and N46VM among other models in the same family. It replaces OEM part numbers A31-N56, A32-N56, and A33-N56.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN46 series compatibility:\u003c\/strong\u003e\n    These models share the same 10.8V power rail, physical form factor, and BMS handshake protocol — one cell covers the full lineup without connector or firmware conflicts.\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 N46 hardware, confirmed the BMS communicates correctly with the EC, and verified the fuel gauge IC registers accurate state-of-charge data.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the N46:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false health warning the N46 EC 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\"\u003eWhy the N46 BIOS flags a new battery as poor health immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe N46 embedded controller reads EEPROM data stored on the old cell and compares it against the new one. A fresh cell has no charge history, so the EC interprets the mismatch as a degraded unit. This triggers the health warning before the battery has run a single cycle. One complete discharge-to-hibernate followed by a full uninterrupted charge gives the EC enough data to recalibrate and clear the flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eN46 shutting down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still has calibration data from the old, worn cell. It maps the new cell's voltage curve incorrectly, so the remaining-charge estimate drops off a cliff under CPU and display load. The laptop hits what it thinks is 0% well before the cell is actually empty. Run two to three full discharge-to-hibernate cycles and the gauge IC will remap to the new cell's actual voltage curve — shutdowns should stop occurring above 10%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409795678298,"sku":"BWCS-AUN56NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409795711066,"sku":"BWCS-AUN56NB-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409795743834,"sku":"BWCS-AUN56NB-3","price":121.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUN56NB-1.webp?v=1779580871","url":"https:\/\/batteryweb.com\/products\/asus-n46-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
