It also fits the 1050, 1000, and 1000E models that share the same battery tray and connector pinout. Voltage and capacity match the original factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1020, 1050, and 1000 series compatibility:\u003c\/strong\u003e\n    These models run the same 11.1V three-cell voltage rail and use an identical connector and BMS handshake protocol. A single cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the 1020 platform. The BMS communicated correctly with the system board — no false fault flags and no premature cutoff under combined CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration after install:\u003c\/strong\u003e\n    After fitting this cell, 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's actual capacity 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\"\u003eAveratec 1020 shutting down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n\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 laptop reads residual EEPROM data from the old cell and plots the wrong discharge slope. Under full CPU plus display load, voltage drops faster than the gauge predicts, and the system hits the hardware low-voltage cutoff before the displayed percentage reaches zero. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% — the fuel gauge IC recalculates the curve against actual cell behaviour and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor or unknown immediately after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health data stored in the battery's EEPROM — on a new cell, that register either holds factory defaults or zeros, which the BIOS flags as degraded or unknown. This is a data mismatch, not a cell fault. Force a full learn cycle: discharge to hibernate cutoff, then charge without interruption to 100%. After one complete cycle the BIOS rewrites its health register from live cell data and the warning clears. Confirm the voltage reads at or above 12.4V at full charge before closing the lid.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410818531418,"sku":"BWCS-AT1020NB-1","price":67.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410818564186,"sku":"BWCS-AT1020NB-2","price":79.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410818596954,"sku":"BWCS-AT1020NB-3","price":87.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AT1020NB-big.webp?v=1779581181","url":"https:\/\/batteryweb.com\/products\/averatec-1020-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
