About this replacement
Asus ZenBook Flip 15 UX562 Series — 11.55V Li-Polymer Replacement Battery (C32N1810)
This is an 11.55V, 7400mAh (85.47Wh) Li-Polymer battery for the Asus ZenBook Flip 15 UX562 lineup. It fits the UX562FD-2G, UX562FN, and UX562FD convertible laptops. It replaces OEM part numbers C32N1810 and 0B200-03070100.
- UX562 series compatibility: All UX562 variants share the same 11.55V three-cell battery bay, connector pinout, and BMS handshake protocol. The same physical cell and EEPROM charge profile works across UX562, UX562FD, UX562FD-2G, and UX562FN without modification.
- Bench tested on actual hardware: We ran this cell through full charge and load cycles on UX562 hardware. The BMS negotiated charge current correctly, and the EC reported cell voltage without fault flags across CPU and display load transitions.
- First-cycle reset on the UX562: After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false "poor health" warning that appears in MyASUS after a cell swap on this platform.
Why the UX562 shuts down at 20–30% after a battery swap
The ZenBook's EC relies on EEPROM data from the previous cell to model remaining capacity. When a new cell goes in, that data is stale. The fuel gauge IC sees a voltage cliff under combined CPU and display load and triggers an emergency shutdown before the gauge reaches zero. Running two or three full discharge-to-hibernate and full-recharge cycles recalibrates the fuel gauge IC against the new cell's actual discharge curve. After calibration, the shutdown threshold shifts back to the correct low-battery range.
MyASUS showing wrong Wh rating after cell replacement
The Wh figure shown in MyASUS and Windows Battery Report pulls from the EEPROM's stored design capacity, not a live cell measurement. A replacement cell may carry a slightly different EEPROM Wh value than the original, which is why the reported figure can differ from the label on the battery. This is an EEPROM metadata difference, not a fault in the cell itself. After two full calibration cycles, the EC updates its learned capacity and the reported Wh value stabilises to reflect the actual cell.
