About this replacement
Asus F560UD / X560UD Series — 10.8V Li-ion Replacement Battery (A31N1730)
This is a 10.8V, 2600mAh (28.08Wh) Li-ion replacement battery for the Asus F560UD and X560UD series laptops, including the F560UD-AX8203T, X560UD-EJ386, X560UD-BQ376, and X560UD-BQ373T among others. OEM part numbers A31N1730 and 0B110-00550100 both reference this same cell configuration. Install this when the original cell no longer holds a charge or the laptop refuses to run off battery at all.
- F560UD / X560UD platform fit: These models share the same 10.8V three-cell architecture, connector pinout, and BMS handshake protocol. The EC firmware expects the same EEPROM signature across all variants in this family, so this cell communicates correctly with the charge controller without any adapter or modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the X560UD platform. The BMS accepted the cell, the charge controller stepped through its CC/CV phases without interruption, and cell voltage held stable at 10.8V nominal under sustained CPU and display load.
- Post-install calibration for the F560UD: After fitting this battery, run the laptop down until Windows triggers hibernate, then charge uninterrupted to 100% before unplugging. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after fitting a new cell
The Asus EC reads health data from the EEPROM on the old cell and caches it. When you swap in a new cell, that cached data persists until a full learn cycle overwrites it. The BIOS health screen can show "Replace" or a low percentage even on a brand-new cell. Run one full discharge to hibernate cutoff, then a single uninterrupted charge to 100%. After that cycle, the EC recalibrates against the new cell's actual charge curve and the health warning clears.
Laptop shuts down at 20–30% remaining after battery swap
This happens when the fuel gauge IC hasn't yet mapped the new cell's voltage-to-capacity curve. Under full CPU plus display load, the cell hits a voltage cliff earlier than the gauge predicts, and the system shuts down to protect itself — even though the displayed percentage still looks reasonable. The fix is two to three full calibration cycles: discharge to hibernate, charge to 100%, repeat. After those cycles the fuel gauge IC tracks the actual voltage curve of the new cell and the premature shutdowns stop.
