The pack dimensions are 290.34 × 89.60 × 5.60mm, matching the original footprint inside the chassis. Compatible OEM part numbers include L19D4PH3, L19M4PH3, 5B10Z49514, 5B10Z49518, 5B10Z49519, and SSB10Z49515.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga S750-14 Pro and Slim 7 Pro 14ACH5 compatibility:\u003c\/strong\u003e\n    These models share the same 15.44V four-cell battery rail, connector pinout, and BMS handshake protocol.

The BMS handshake completed normally, charge accepted without interruption, and the protection circuit triggered correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for the Yoga S750-14 Pro:\u003c\/strong\u003e\n    After fitting this battery, 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 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLenovo's embedded controller reads cycle count, charge history, and rated capacity from EEPROM data stored in the outgoing cell. When a new cell is installed, that EEPROM register is blank or carries mismatched values, so the BIOS flags the battery as degraded before it has run a single cycle. This is a firmware interpretation issue, not a cell fault. Run one complete discharge-to-hibernate followed by a full uninterrupted charge. After two to three cycles the fuel gauge IC recalibrates against the new cell chemistry and the health status normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC still holds calibration data from the old, degraded cell. The percentage readout appears stable, but the new cell hits a voltage cliff under combined CPU and display load that the uncalibrated gauge did not anticipate. The system interprets the sudden voltage drop as a critical low-battery event and shuts down to protect the hardware. To fix it, fully discharge to hibernate-cutoff — do not force-shutdown — then charge to 100% without interruption. Repeat this cycle twice more until the gauge tracks accurately against real cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409653399642,"sku":"BWCS-LVS750NB-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409653432410,"sku":"BWCS-LVS750NB-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409653465178,"sku":"BWCS-LVS750NB-3","price":125.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVS750NB-1.webp?v=1779580312","url":"https:\/\/batteryweb.com\/products\/lenovo-yoga-s750-14-pro-replacement-battery-1544v-3850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
