Schenker XMG PRO 17-M19 Compatible Battery 11.1V 5400mAh

Schenker XMG PRO 17-M19 MSB — 11.1V Li-ion Replacement Battery

This is an 11.1V 5400mAh (59.94Wh) lithium-ion battery for the Schenker XMG PRO series mobile workstations. It fits the XMG PRO 17-M19 MSB, XMG PRO 15-M19 GFP, XMG PRO 17-E20, XMG PRO 17-E20 vqr, and nine additional models sharing the same battery bay and connector. Dimensions are 137.80 × 75.00 × 22.30mm.

• XMG PRO 15 and 17 series compatibility: These models share a common battery bay geometry, connector pinout, and BMS communication protocol across the M19 and E20 platform generations. The cell voltage rail and handshake logic are consistent across all listed variants, so the same replacement cell works without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the XMG PRO platform and logged BMS communication at each stage. The protection circuit engaged correctly at low-voltage cutoff, and charge termination signalled at 100% without overvolt event.
• First-cycle calibration after install: After fitting the new cell, run one complete discharge to hibernate-cutoff — do not interrupt — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health or capacity warning that appears after every cell swap on XMG systems.

BIOS reporting battery health as poor immediately after replacement

The XMG PRO BIOS reads health data from EEPROM registers on the battery's fuel gauge IC. When a new cell is installed, those registers still hold degradation data written by the old cell. The BIOS compares measured capacity against the stored rated value and flags the result as poor — even though the new cell is fully functional. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn-cycle data and clears the warning. If the BIOS still shows poor health after two full cycles, check that resting open-circuit voltage reads at least 12.4V before connecting.

XMG PRO shuts down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The OS reads a percentage derived from the old cell's data, so the displayed figure and the real cell voltage diverge. Under combined CPU and display load, the cell hits its low-voltage cutoff before the OS registers 0%, triggering an immediate shutdown. Run two full discharge-to-hibernate and charge-to-100% cycles without interruption — after the second cycle the fuel gauge IC recalculates its reference curve and the shutdown threshold aligns with the displayed percentage. Confirm calibration is complete by checking that cell voltage reads between 11.0V and 11.1V at the point the OS shows approximately 10% remaining.
