C41N2110 Asus Zenbook 17 Fold OLED Compatible Battery 15.48V 4800mAh

Asus Zenbook 17 Fold OLED (UX9702AA) — 15.48V Li-Polymer Replacement Battery (C41N2110)

This 15.48V, 4800mAh (74.3Wh) Li-Polymer battery replaces the OEM C41N2110 cell in the Asus Zenbook 17 Fold OLED (UX9702AA). It powers the foldable 17-inch OLED panel, the processor, and all onboard components. The 0B200-04220000 is the alternate OEM reference for the same unit.

• Zenbook 17 Fold OLED compatibility: The UX9702AA runs a 4-cell Li-Polymer stack at 15.48V to handle both the full-size OLED load and the hinge-flex routing. The connector pinout and BMS handshake are specific to this chassis — no other Zenbook series shares this cell configuration.
• Bench tested on actual hardware: We cycled this cell through charge, discharge, and full CPU-plus-display load on the UX9702AA. The BMS negotiated charge termination correctly and held voltage above the low-battery shutdown threshold under sustained display brightness.
• Post-install calibration on the Zenbook 17 Fold: After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. The Zenbook's BIOS battery learn cycle needs this reset — skipping it leaves a false "poor health" warning in MyASUS that won't clear on its own.

BIOS reporting poor battery health immediately after swapping the C41N2110

The Zenbook 17 Fold BIOS reads health data stored in the old cell's EEPROM. When a new cell goes in, that EEPROM data is gone, and the BIOS flags the battery as degraded before it has run a single cycle. This is a firmware interpretation issue, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite the health register. After that cycle, MyASUS and Windows Battery Report should show accurate figures.

Zenbook 17 Fold shutting down at 20–30% battery remaining

This happens when the cell hits a voltage cliff — the point where voltage drops sharply under full CPU and OLED panel load faster than the fuel gauge IC can track. The BIOS sees a sudden voltage sag, interprets it as empty, and triggers an emergency shutdown even though the state-of-charge percentage still reads 20–30%. A degraded or poorly calibrated cell reaches that cliff earlier in the discharge curve. Run the full calibration cycle described above, and check that charge reaches at least 16.1V at the termination point before disconnecting power.
