It fits the 82K201EVMX and over 120 other 15ACH6 variants sharing the same battery bay and connector. Install it when the original cell no longer holds a charge or the laptop refuses to run unplugged.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e15ACH6 series fit:\u003c\/strong\u003e\n    All listed 15ACH6 models run the same 11.52V three-cell architecture with an identical connector pinout and BMS handshake protocol. Part numbers L20C3PC2, L20D3PC2, L20L3PC2, L20M3PC2, SSB10X55571, and SSB11B96720 are all cross-compatible within this chassis.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on an IdeaPad Gaming 3 15ACH6 unit. The BMS communicated correctly with the EC, charge accepted at the expected rate, and no fault codes triggered during either cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after swap:\u003c\/strong\u003e\n    After installing this cell, run a full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically appears after any cell replacement 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\"\u003eLaptop shutting down at 20–30% remaining after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 15ACH6 draws hard on the battery when the Ryzen CPU and display both run at full load. If the new cell hasn't been calibrated, the fuel gauge IC maps voltage curves from the old cell's EEPROM data. The EC reads a false state-of-charge, triggers a low-voltage cutoff while the gauge still shows charge remaining, and the laptop shuts down without warning. Run one complete discharge-to-hibernate cycle followed by a full uninterrupted charge to force the fuel gauge IC to re-baseline against the new cell's actual voltage curve.\u003c\/p\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\"\u003eThis happens because the embedded controller reads health data stored in the old cell's EEPROM and compares it against the new cell's reported capacity — the mismatch flags a degraded-battery warning before a single charge cycle completes. It is not a fault with the replacement cell. Navigate to Lenovo Vantage or the BIOS battery settings and initiate a battery gauge reset or learn cycle. After one full discharge-to-cutoff and recharge, the health indicator should return to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409572331610,"sku":"BWCS-LPG315NB-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409572364378,"sku":"BWCS-LPG315NB-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409572397146,"sku":"BWCS-LPG315NB-3","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LPG315NB-1.webp?v=1779580060","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-gaming-3-15ach6-82k201evmx-replacement-battery-1152v-3750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
