It cross-references a wide range of OEM part numbers including AS07A51, AS07A72, AS07A31, and AS07A42, covering over two dozen NV-series models. Capacity comes in at 73.26Wh — matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNV52 series platform fit:\u003c\/strong\u003e\n    The NV5207U, NV5211U, NV5212U, NV5213U, and the rest of the NV52 line share the same voltage rail, connector pinout, and BMS handshake protocol. One cell design covers the entire run because Gateway standardised the battery interface across this chassis generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an NV52-series unit and monitored BMS communication throughout. The protection circuit held cutoff at the correct thresholds and charge acceptance completed without error flags across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff — do not force-shutdown — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on first boot after any 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 replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NV52 BIOS reads EEPROM data written by the original factory cell. When a new cell is installed, that stored data no longer matches what the fuel gauge IC is reporting, so the BIOS flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS learn cycle to overwrite the old EEPROM reference values. After one or two full cycles the health status normalises.\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 happens when a degraded original cell can no longer sustain voltage under combined CPU and display load — the cell hits a voltage cliff faster than the fuel gauge IC can track. At high draw, terminal voltage collapses below the BMS cutoff threshold before the displayed percentage reaches zero. If you see this on an original battery, the cell is at end of life regardless of the percentage shown. Replacing the cell and running a full calibration cycle will realign the fuel gauge IC; confirm the fix by checking that reported voltage at 20% sits above 10.8V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410815418458,"sku":"BWCS-AC4310HB-1","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410815451226,"sku":"BWCS-AC4310HB-2","price":139.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410815483994,"sku":"BWCS-AC4310HB-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4310HB-1.webp?v=1779581180","url":"https:\/\/batteryweb.com\/products\/gateway-nv5207u-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
