It matches OEM part numbers L12S3F01, L12C3A01, and L12M3A01. Install it when the original cell no longer holds a useful charge or fails to register in the OS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS210 and S215 platform compatibility:\u003c\/strong\u003e\n    Both the S210 and S215 lines share the same 10.8V three-cell architecture, connector pinout, and BMS communication protocol — which is why one cell covers all four variants including the Touch models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on the S210 platform. The BMS handshake completed correctly, charge current was accepted without fault codes, and the fuel gauge IC tracked voltage accurately after two calibration cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the IdeaPad S210:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate-cutoff under normal use — do not force-shutdown — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle 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\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IdeaPad S210 BIOS reads health data from EEPROM registers written by the original cell. When a new cell arrives, those registers don't match the new cell's chemistry profile, so the BIOS flags the battery as degraded even though the cell is fresh. This is not a fault with the replacement — it's a data mismatch. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the fuel gauge IC enough data to rewrite those registers. After two cycles the health warning clears and the reported capacity stabilises.\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 hasn't yet calibrated against the new cell's actual voltage curve. The S210's CPU and display together draw enough current that a miscalibrated gauge hits its low-voltage threshold earlier than the percentage readout suggests. The cell voltage at that point is typically dropping below 10.0V under load — which triggers the hardware shutdown before the OS can gracefully power down. The fix is the same calibration cycle: discharge to hibernate-cutoff, then charge fully to 100V without interruption. Repeat once more if the shutdown point is still showing above 15%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409755799642,"sku":"BWCS-LVS210NB-1","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409755832410,"sku":"BWCS-LVS210NB-2","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409755865178,"sku":"BWCS-LVS210NB-3","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVS210NB-1.webp?v=1779580733","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-s210-replacement-battery-108v-2150mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
