It replaces a failed or degraded original cell and restores portable operation without AC power. Voltage and connector match the original specification across all three models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS1 PRO, S1 X1, and S2 PRO compatibility:\u003c\/strong\u003e\n    All three models run the same 14.8V battery rail with the same connector pinout and BMS handshake protocol, so one replacement cell covers the entire platform without wiring or firmware differences.\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 the S1 PRO platform. The BMS communicated correctly with the motherboard, charge termination triggered at 100%, and low-voltage cutoff engaged at the expected threshold before cell damage could occur.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a full discharge down to hibernate cutoff, then charge uninterrupted to 100%. That single cycle resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Lingrui hardware.\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 after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS stores capacity and health data in EEPROM tied to the original cell. When a new cell is installed, that stored data no longer matches the actual chemistry, so the firmware flags poor health immediately. This is not a fault with the replacement battery. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite the learn-cycle data against the new cell. After two to three cycles the health indicator should read normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The OS reads a percentage based on old EEPROM data, but the cell hits its real voltage floor earlier than the software expects — triggering an abrupt shutdown. It is not a defective cell. Run three complete discharge-to-hibernate and full-charge cycles to allow the fuel gauge IC to remap the curve. After calibration, the shutdown threshold should align with the actual remaining capacity, and the display should read 0–5% before hibernate engages.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409542316122,"sku":"BWCS-ARG200NB-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409542348890,"sku":"BWCS-ARG200NB-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409542381658,"sku":"BWCS-ARG200NB-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARG200NB-1.webp?v=1779579964","url":"https:\/\/batteryweb.com\/products\/lingrui-s1-pro-replacement-battery-148v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
