It fits the 10-inch detachable notebook platform, restoring power to the keyboard-base battery unit. Voltage and connector match the OEM specification across all 82AT and 82HK variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIdeaPad Duet 3 10IGL5 platform fit:\u003c\/strong\u003e\n    The 82AT and 82HK sub-variants share the same battery bay geometry, connector pinout, and BMS handshake protocol — which is why a single cell covers the full Duet 3 10IGL5 range. The 7.68V nominal rail matches the Celeron N4020 platform's power delivery spec exactly.\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 an 82AT unit. The BMS accepted the cell without fault codes, the protection circuit engaged correctly at low-voltage cutoff, and charge current tapered as expected near full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate-cutoff under normal use, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity — skipping it leaves the fuel gauge reading inaccurate health data from the previous cell's EEPROM.\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 immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IdeaPad Duet 3 BIOS reads health data cached in the old cell's EEPROM. When a new cell goes in, the BIOS compares its current readings against stale reference data and flags the battery as degraded — even when the cell is brand new. This is not a fault with the replacement battery. Running one full discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and clears the false warning. After two or three full cycles, the health indicator will align to the new cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts 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 discharge curve. The gauge loses accuracy at the low end and triggers a shutdown before the battery is actually empty — or the displayed percentage does not match the real state of charge. It is not a cell defect. Run two to three full discharge cycles from 100% down to automatic hibernate, then charge fully each time. After calibration, shutdown should occur at or below 5% with the low-battery threshold set to its default value in power settings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409653629018,"sku":"BWCS-LVP382NB-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409653661786,"sku":"BWCS-LVP382NB-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409653694554,"sku":"BWCS-LVP382NB-3","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVP382NB-1.webp?v=1779580312","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-3-10igl5-82at-replacement-battery-768v-3850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
