It replaces OEM part numbers AS07A32, AS07A51, AS07A72, and a range of BT.006xx Acer\/Gateway codes. The physical dimensions are 208.20 x 44.94 x 19.90mm — confirm these against your current cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNV52 series fit group:\u003c\/strong\u003e\n    The NV5207U, NV5211U, NV5212U, and NV5213U share the same 11.1V three-cell battery bay, connector pinout, and BMS handshake protocol — which is why one cell covers all of them. Voltage rail and thermistor wiring are identical across the run.\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 chassis and confirmed the BMS accepted the new cell without triggering a charge-fault flag. Charge current stepped down correctly at 95% as the protection circuit expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on NV52 BIOS:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it hibernates at cutoff, 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 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\"\u003eBIOS reporting battery health as poor immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gateway NV52 BIOS stores charge history and health data in the old cell's EEPROM. When you swap cells, the BIOS compares the new cell's reported state against that stored history and flags a mismatch as poor health. This is a firmware read error, not a fault in the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle and the warning clears on reboot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down hard at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below what the board needs under combined CPU and display load, even though the OS fuel gauge still shows charge remaining. The fuel gauge IC estimates state-of-charge from a model built on the old cell — it hasn't calibrated against the new one yet. The voltage cliff happens faster than the gauge predicts during the first few cycles. Run two full discharge-to-hibernate cycles and the gauge IC recalibrates; the cutoff point should stabilise above 10% shown after that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410853822554,"sku":"BWCS-AC4310NB-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410853855322,"sku":"BWCS-AC4310NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410853888090,"sku":"BWCS-AC4310NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4310NB-1.webp?v=1779581356","url":"https:\/\/batteryweb.com\/products\/gateway-nv5207u-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
