It fits the 82XE variant range, including 82XE0001RK through to the broader 82XE lineup. Cross-reference OEM part numbers L22B3PA3, L22C3PA3, L22D3PA3, L22L3PA3, L22M3PA3, 5B11N45396, or SB11K39363 before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIdeaPad Slim 5 14ABR8 series compatibility:\u003c\/strong\u003e\n    All 82XE variants share the same three-cell Li-Polymer pack, connector pinout, and BMS handshake. The voltage rail sits at 11.31V nominal — any deviation trips the EC and prevents charging from starting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a 14ABR8 chassis. The BMS initialised on first boot, the EC recognised cell chemistry without firmware prompts, and charge current ramped correctly through CC\/CV phases to full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting, run one full discharge 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 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IdeaPad Slim 5 EC reads health data from the battery's EEPROM on first connection. When a new cell arrives with factory EEPROM values that differ from the old pack's learned data, the BIOS flags it as degraded or unknown. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate then a full uninterrupted charge — the BIOS battery learn cycle rewrites the stored health data against the new cell's actual charge curve. The warning clears after one to two calibration cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% remaining after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on this platform maps state-of-charge against the old cell's discharge curve stored in memory. A new cell has a different voltage-versus-capacity profile, so the IC misreads remaining charge and triggers shutdown well before the pack is actually empty. The cutoff happens because the reported voltage hits the low-threshold before the gauge recalibrates. To fix it, run two full discharge-to-hibernate and charge-to-100% cycles — by the second cycle, the fuel gauge IC recalibrates to the new cell and the percentage readout stabilises above 11.1V at the point the laptop would otherwise shut down.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409527079002,"sku":"BWCS-LVP233NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409527111770,"sku":"BWCS-LVP233NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409527144538,"sku":"BWCS-LVP233NB-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVP233NB-1.webp?v=1779579940","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-slim-5-14abr8-82xe0001rk-replacement-battery-1131v-4100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
