It fits the Yoga 510-15ISK, 510-14AST, 510-14IKB, and over a dozen closely related 510 variants. OEM part numbers covered include L15L2PB1, L15M2PB1, L15C2PB1, 5B10K84491, 5B10K84639, and 5B10K85056.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga 510 series compatibility:\u003c\/strong\u003e\n    All Yoga 510 variants listed share the same 7.6V battery rail, identical 219.50 × 118.96 × 6.30mm cell footprint, and the same BMS handshake protocol — so one cell covers the full platform without connector or firmware conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Yoga 510-14IKB through full charge and load cycles. The BMS communicated correctly with the EC, charge current tapered normally at capacity, and no protection trips occurred under sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Yoga 510:\u003c\/strong\u003e\n    After installation, run one full discharge to hibernate cutoff — let the laptop power off on its own — 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\"\u003eWhy the Yoga 510 BIOS flags a new cell as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Yoga 510 stores battery health data in EEPROM on the old cell's fuel gauge IC. When a new cell is installed, that EEPROM data is gone. The BIOS reads zero learned cycles and no charge history, so it reports poor health or an unknown battery — even when the new cell is fully functional. Running a complete discharge-to-hibernate then a full uninterrupted charge forces the embedded controller to write fresh baseline data. After one to two full cycles, the health indicator updates to reflect the actual cell condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eYoga 510 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a calibration issue. Under combined CPU and display load, a degraded or uncalibrated cell drops below the EC's minimum voltage threshold before the fuel gauge hits zero — the system cuts power to protect the hardware. On a new replacement cell, it usually means the fuel gauge IC has not yet mapped the discharge curve of the new chemistry. Discharge fully to hibernate cutoff twice in a row, charging to 100% each time between cycles. If the shutdowns stop after two cycles, calibration was the cause; if they continue, check that cell voltage at the connector reads at least 7.0V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409724407898,"sku":"BWCS-LVG510NB-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409724440666,"sku":"BWCS-LVG510NB-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409724473434,"sku":"BWCS-LVG510NB-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVG510NB-1.webp?v=1779580558","url":"https:\/\/batteryweb.com\/products\/lenovo-yoga-510-replacement-battery-76v-4600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
