It fits the Aspire V5-471G, V5-431, V5-531, and 31 additional V5 variants. Install it when the original cell can no longer hold a charge or the system shuts down unexpectedly under load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV5 series compatibility:\u003c\/strong\u003e\n    All listed Aspire V5 models share the same 14.8V four-cell Li-ion rail, the AL12A32 connector layout, and a common BMS handshake protocol — so one replacement cell works across the full V5 lineup without adapter or firmware difference.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a V5-471G. The BMS reported correct voltage at each stage, accepted charge without cutoff errors, and held stable voltage under combined CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for V5 units:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears 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 Aspire V5 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Aspire V5 BIOS maps discharge curves from the previous cell's EEPROM data. After a swap, it still references the old voltage curve, so when the new cell hits a voltage the BIOS misreads as near-empty, it triggers an emergency shutdown. This is not a fault with the replacement cell. Run one full discharge to hibernate cutoff followed by an uninterrupted charge to 100% — this forces the fuel gauge IC to re-map against the new cell's actual discharge profile. After two to three full cycles, the shutdown threshold corrects itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWindows and the Acer BIOS read health data stored in the battery's EEPROM. A new cell ships with factory EEPROM values that don't match the discharge history the BIOS expects, so it flags the battery as degraded or unknown. This is a data mismatch, not a defective cell. Complete the calibration cycle above — discharge fully to hibernate cutoff, then charge to 100% without interruption — and the BIOS will rewrite the health register against actual measured capacity. Check battery health again after the first full cycle completes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409799610458,"sku":"BWCS-ACV500NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409799643226,"sku":"BWCS-ACV500NB-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409799675994,"sku":"BWCS-ACV500NB-3","price":121.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACV500NB-1.webp?v=1779580970","url":"https:\/\/batteryweb.com\/products\/acer-aspire-v5-replacement-battery-148v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
