It uses the same connector and BMS handshake expected by the Aspire platform. Cross-references include AS10D31, AS10D51, AS10D71, BT.00607.125, and over 30 additional OEM part numbers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAspire AS10D platform fit:\u003c\/strong\u003e\n    The AS10D series cells all share a common 11.1V three-cell rail, identical physical connector, and the same BMS communication protocol. That is why one replacement cell covers hundreds of Aspire model variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an Aspire chassis and monitored the BMS handshake through a full charge cycle. The protection circuit responded correctly to overvoltage and overcurrent thresholds, and the system BIOS recognised the cell without error flags on connection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery alone until it reaches hibernate cutoff — do not interrupt — then charge uninterrupted to 100%. This forces the BIOS learn cycle to reset against the new cell's actual capacity curve 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 BIOS flags a new cell as poor health or unknown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Aspire BIOS stores battery health data in EEPROM and compares incoming cell readings against that cached profile from the old battery. A new cell has different internal resistance and state-of-charge curves, so the BIOS initially reads a mismatch and reports poor health or an unknown device. This is not a fault in the new cell. Running one full discharge-to-hibernate then a complete uninterrupted charge overwrites the cached EEPROM baseline and brings the health indicator in line with the actual cell condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAspire shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge believes 25% remains while the actual cell voltage has already dropped below the safe discharge floor under combined CPU and display load. The BMS triggers a hard cutoff to protect the cells — what you see on screen is the uncalibrated percentage at that moment, not the true state of charge. Complete two full discharge-to-hibernate and full recharge cycles; after that the fuel gauge IC will track the new cell accurately and the early shutdowns will stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410739822682,"sku":"BWCS-AC4551HB-1","price":124.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410739855450,"sku":"BWCS-AC4551HB-2","price":143.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410739888218,"sku":"BWCS-AC4551HB-3","price":157.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC4551HB-1.webp?v=1779581043","url":"https:\/\/batteryweb.com\/products\/acer-aspire-4333-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
