It uses the same connector and BMS communication protocol as the factory pack. Fits models cross-referencing OEM part numbers including L08L6C02, L08S6C02, and 57Y6266, among others listed above.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG430 series fit:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell rail, identical connector pinout, and the same BMS handshake expected by the EC firmware. A replacement cell on the same voltage and protocol responds correctly to charge commands from the system board without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge initiation, BMS wake-up, and load discharge on G430-series hardware. The protection circuit engaged correctly at low-voltage cutoff and the system board recognised the pack without fault codes during our test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration tip:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that commonly appears after every cell swap on 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 G430 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe G430 stores cycle count, capacity data, and health flags in EEPROM on the original battery pack. When a new cell is installed, the BIOS reads that data as absent or zeroed out and flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running a full discharge-to-hibernate followed by an uninterrupted full charge lets the EC rewrite its fuel gauge registers to match the new cell. After one or two full cycles, the health indicator normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated to the new cell's voltage curve. The OS reads a stored discharge profile from the old, degraded cell and miscalculates the remaining capacity. Under combined CPU and display load, voltage drops faster than the uncalibrated gauge predicts, and the system hits hardware undervolt cutoff before the screen shows zero. Run two full discharge-to-hibernate cycles with no interruptions. After calibration, the gauge tracks the actual voltage curve and the early shutdowns stop. Target a resting voltage of 12.5–12.6V at a full charge to confirm the cell is performing within spec.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410810503258,"sku":"BWCS-LVG430NB-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410810536026,"sku":"BWCS-LVG430NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410810568794,"sku":"BWCS-LVG430NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVG430NB-1.webp?v=1779581158","url":"https:\/\/batteryweb.com\/products\/lenovo-3000-g430-4152-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
