Schenker L140BAT-4 VIA 14 Replacement Battery 7.7V 9300mAh

Schenker VIA 14 / Work 17 Tiger Lake-H — 7.7V Li-Polymer Replacement Battery (L140BAT-4)

This is a 7.7V, 9300mAh (71.61Wh) lithium-polymer cell for the Schenker VIA 14, VIA 14 Late 2020, and Work 17 Tiger Lake-H laptops. It replaces OEM part L140BAT-4 and connects directly to the motherboard via the original harness. Capacity figures come from the product data — not web estimates.

• VIA 14 and Work 17 Tiger Lake-H compatibility: Both platforms share the same physical cell footprint, connector pinout, and BMS communication protocol over SMBus. The L140BAT-4 part number covers all three listed variants — the BIOS reads the same EEPROM data block regardless of build date.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the VIA 14 platform. The BMS reported capacity correctly after two calibration cycles, and the protection circuit triggered cleanly at low-voltage cutoff without requiring a hard reset.
• First cycle after installation: After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% without putting the laptop to sleep mid-charge. This forces the BIOS battery learn cycle to reset and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting the L140BAT-4

The Schenker VIA 14 BIOS reads charge history and cycle count data stored in the old cell's EEPROM. When a new cell is installed, that data block is blank or mismatched, and the BIOS flags it as degraded. This is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle. After two full cycles, the BIOS should report health above 95% and capacity close to the rated 71.61Wh.

Laptop shuts off at 20–30% remaining shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The percentage displayed is still mapped to the old cell's chemistry profile, so the voltage cliff arrives earlier than the OS predicts. Under combined CPU and display load, the cell voltage drops faster than the uncalibrated gauge expects, and the BIOS pulls the plug before the screen reads zero. Run two full discharge-to-hibernate cycles and the fuel gauge IC will remap the curve to the new cell — after that, shutdowns at 20–30% should stop.
