It fits the S340-13IML variants including 81UM001GTA, 81UM000PJP, and the broader IdeaPad S340-13 series. Cross-reference OEM part numbers SB10W67222, 5B10U95572, or L18C3PF8 before ordering to confirm fitment.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS340-13 series fitment:\u003c\/strong\u003e\n    These slim 13-inch variants share the same battery bay dimensions, connector pinout, and BMS communication protocol — the same physical cell and firmware handshake covers all S340-13IML configurations listed above.\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 S340-13IML platform. The BMS negotiated correctly with the BIOS, charge current stepped down properly at the 80% and 95% thresholds, and no fault codes were logged during the full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the S340-13IML:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Lenovo Vantage 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 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S340-13IML BIOS reads health data from the battery's EEPROM on first boot. The old cell wrote its degraded cycle count and capacity history into that data — the BIOS carries that reading across until a learn cycle is completed. This is not a fault with the new cell. Run one full discharge to the point where the laptop hibernates, then charge to 100% without interruption. After that cycle, the BIOS recalculates health against the new cell's actual capacity and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the fuel gauge\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 voltage curve. The IC is still using discharge models built from the old, degraded cell — it misreads the voltage cliff and triggers shutdown early. The fix is two to three complete discharge-and-charge cycles without interruption. After calibration cycles are complete, the gauge tracks accurately and the early shutdown stops. If it persists past three cycles, check that the BIOS battery charge limit in Lenovo Vantage is not set below 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409533960282,"sku":"BWCS-LVS341NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409533993050,"sku":"BWCS-LVS341NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409534025818,"sku":"BWCS-LVS341NB-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVS341NB-1.webp?v=1779579986","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-s340-13iml-replacement-battery-111v-3650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
