It fits the A3, A320, A320 Plus, A360, and over a dozen additional A-series variants. When the original cell degrades and the laptop no longer holds a charge away from the wall, this battery restores full mobile operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA3 and A320 series compatibility:\u003c\/strong\u003e\n    These models share a common 14.8V four-cell battery bay, the same connector pinout, and a compatible BMS communication protocol — which is why one replacement cell covers the full A-series range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, discharge, and thermal cycling on A-series hardware. The BMS accepted the cell without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on the A3:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-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 poor battery health after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A-series BIOS reads battery health from EEPROM data written by the original cell. When a new cell arrives, its EEPROM values don't match what the BIOS learned from the old one, so the firmware flags it as degraded. This is a calibration mismatch, not a fault with the replacement. One full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the BIOS learn cycle and rewrites the health status against the new cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop cutting off at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated its discharge curve against the new cell chemistry. The displayed percentage is still tracking the old cell's voltage profile, so the reading diverges from actual state of charge under CPU and display load. When real cell voltage drops to the BMS cutoff threshold, the laptop shuts down even though the gauge still shows capacity remaining. Run two to three full discharge-and-recharge cycles and the fuel gauge IC will recalibrate its curve to the new cell — the cutoff point will align with 0% as expected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410824724570,"sku":"BWCS-ADA440NB-1","price":82.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410824757338,"sku":"BWCS-ADA440NB-2","price":97.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410824790106,"sku":"BWCS-ADA440NB-3","price":107.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADA440NB-1.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/fic-a3-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
