It fits the NV5207U, NV5211U, NV5212U, NV5213U, and over 24 additional NV52-series models sharing the same connector and BMS handshake. Cross-references include AS07A32, AS07A51, AS07A72, AS07A31, AS07A41, AS07A42, AS07A52, and several BT.00xxx OEM part numbers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNV52-series platform fit:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell rail, identical connector pinout, and the same BMS communication protocol — which is why one cell works across the full NV52 lineup without any 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 full charge and discharge cycles on an NV52-series unit. The BMS handshake completed correctly, charge acceptance held steady across all three cell groups, and the protection circuit triggered cleanly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on NV52 notebooks:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power down to hibernate cutoff, then charge uninterrupted to 100% without using the machine. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the NV52 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gateway NV52 BIOS stores capacity and health data from the previous cell in its EEPROM. When a new cell goes in, that stored data does not automatically clear — so the system flags the replacement as degraded before it has run a single cycle. This is a firmware read issue, not a fault with the new battery. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS learn cycle to overwrite the old EEPROM values with accurate readings from the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom appears when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The percentage shown is calculated from stale reference data, so the displayed value drifts well above zero while the real cell voltage has already dropped below the safe threshold. Under full CPU and display load, the voltage cliff arrives faster than the uncalibrated gauge predicts, and the system shuts down to protect the cell. Run two to three full discharge-to-hibernate and uninterrupted recharge cycles — after that the fuel gauge IC recalibrates and the shutdown will align with the correct remaining capacity, typically below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410815713370,"sku":"BWCS-AC4310DB-1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410815746138,"sku":"BWCS-AC4310DB-2","price":142.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410815778906,"sku":"BWCS-AC4310DB-3","price":155.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4310DB-1.webp?v=1779581180","url":"https:\/\/batteryweb.com\/products\/gateway-nv5207u-replacement-battery-111v-8800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
