It matches OEM part numbers 45N1116 and 45N1117. At 23.31Wh, it restores the portable power capacity lost to cycle-degraded factory cells.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX230s and X240s platform fit:\u003c\/strong\u003e\n    Both the X230s and X240s series share the same 11.1V battery rail, connector pinout, and BMS handshake protocol — that is why one cell covers all four listed models, including the touchscreen variants.\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 X230s unit. The BMS communicated correctly with the BIOS, charge termination triggered at the expected voltage, and no protection cutoffs fired under normal CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle BIOS reset procedure:\u003c\/strong\u003e\n    After fitting this cell, let the laptop discharge fully to hibernate cutoff, then charge uninterrupted to 100% without interruption. This single learn cycle resets the BIOS battery calibration and clears the inaccurate health warning that appears on almost every cell swap in this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ThinkPad X230s shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe X230s fuel gauge IC builds a discharge model against the previous cell's chemistry data stored in EEPROM. When a new cell goes in, that model is stale — it predicts a voltage floor that does not match the new cell's actual discharge curve. Under combined CPU and display load, the measured cell voltage drops faster than the old model expects, and the BIOS triggers an emergency shutdown before the actual remaining capacity is exhausted. Running one full discharge-to-hibernate followed by a full uninterrupted charge retrains the IC against the new cell. After two or three full cycles the reported percentage tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting incorrect Wh rating after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh value displayed in BIOS and Lenovo Vantage is read from the battery's EEPROM, not measured live. Replacement cells occasionally carry EEPROM values from a different production batch, which can show a Wh figure that does not match the 23.31Wh specification on this cell. This is a data mismatch, not a capacity fault — the actual stored energy is correct. If the wrong figure concerns you, cross-check with a full discharge cycle and monitor the real-world drain against your workload rather than relying on the BIOS readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409756618842,"sku":"BWCS-LVX220NB-1","price":70.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409756651610,"sku":"BWCS-LVX220NB-2","price":82.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409756684378,"sku":"BWCS-LVX220NB-3","price":91.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVX220NB-1.webp?v=1779580734","url":"https:\/\/batteryweb.com\/products\/lenovo-thinkpad-x230s-ultrabook-replacement-battery-111v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
