It fits the 82XG variant across all regional SKUs and matches the original connector, dimensions, and BMS handshake. OEM part numbers covered include L22C4PA5, L22D4PA5, L22M4PA5, 5B11K39349, and over a dozen related sub-part codes.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIdeaPad Slim 5 16ABR8 series fit:\u003c\/strong\u003e\n    All 82XG sub-variants share the same 15.36V four-cell rail, connector pinout, and BMS communication protocol — which is why one cell covers 230-plus regional configurations without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an 82XG board and confirmed the BMS completed its handshake on first boot, reported correct voltage, and accepted a full charge without triggering overvoltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates at low charge, then charge uninterrupted to 100%. This forces the BIOS to complete its 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 poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IdeaPad Slim 5 uses an embedded controller that stores charge history from the previous cell in EEPROM. When a new cell is installed, that stored data no longer matches actual cell behaviour, so the BIOS flags the battery as degraded. This is not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — the BIOS battery learn routine will overwrite the stale EEPROM data and the health warning will clear on the next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop 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 is still calibrated to the old, degraded cell and has not yet mapped the new cell's actual voltage curve. Under combined CPU and display load, the new cell hits a voltage point the IC interprets as critically low — triggering shutdown well above actual depletion. Run two to three full discharge-and-charge cycles to let the fuel gauge recalibrate against the new cell's chemistry. After calibration, the laptop should sustain operation down to the intended 3.2V per-cell cutoff before shutting down.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409643667546,"sku":"BWCS-LVP245NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409643700314,"sku":"BWCS-LVP245NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409643733082,"sku":"BWCS-LVP245NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVP245NB-1.webp?v=1779579940","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-slim-5-16abr8-replacement-battery-1536v-4800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
