Schenker VIA 14 L140BAT-2 Replacement Battery 7.7V 4650mAh

Schenker VIA 14 — 7.7V Li-Polymer Replacement Battery (L140BAT-2)

This is a 7.7V, 4650mAh (35.81Wh) lithium-polymer battery for the Schenker VIA 14 and VIA 14 Late 2020 notebooks, as well as the Work 17 Tiger Lake-H. It replaces OEM part number L140BAT-2 directly. The cell matches the original voltage rail and connector pinout used across these models.

• VIA 14 and Work 17 Tiger Lake-H compatibility: Both platforms share the L140BAT-2 form factor, the same 7.7V two-cell Li-Polymer configuration, and an identical SMBus BMS handshake. The connector and PCB locking tab are the same across all three listed fit models.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a VIA 14 unit. The BMS communicated correctly with the BIOS, reported state-of-charge accurately after calibration cycles, and held charge threshold without tripping a fault cutoff.
• Post-install calibration on the VIA 14: After fitting the new cell, run one full discharge to hibernate cutoff — let the machine shut itself off, not a manual power-down. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on first boot after every cell swap.

The VIA 14 BIOS reads health data from EEPROM registers on the battery's BMS, not from live voltage alone. A brand-new cell ships with factory EEPROM values that don't match the laptop's stored history, so the BIOS flags it as degraded. This is not a fault with the cell. Running one full discharge-to-hibernate followed by an uninterrupted full charge forces the BIOS to rewrite its learn-cycle data against the new cell's actual capacity curve. After two to three of these cycles, the health reading normalises.

This happens when the fuel gauge IC's capacity map is still calibrated to the old, degraded cell. The OS reads a percentage based on a stale reference point, so the displayed figure and the cell's actual remaining voltage diverge sharply under load. When the CPU and display pull peak current simultaneously, the cell voltage drops below the BMS cutoff threshold before the OS gauge reaches 0%. Discharge fully to hibernate cutoff, charge to 100% without interruption, and repeat this twice — the fuel gauge IC recalibrates against the new cell and the shutdown threshold aligns correctly.
