About this replacement
Asus TUF Dash F15 FX517ZE / Zenbook Pro 14 Duo OLED — 15.48V Li-Polymer Replacement Battery (C41N2101)
This is a 15.48V, 4650mAh (71.98Wh) lithium-polymer replacement battery for the Asus TUF Dash F15 FX517ZE-HN046W and a broad range of compatible Asus notebooks including the Zenbook Pro 17 UM6702RA and Zenbook Pro 14 Duo OLED UX8402ZE. It replaces OEM part numbers C41N2101, 0B200-04110000, and 0B200-04110100. The cell chemistry and connector match the original specification exactly.
- TUF Dash F15 and Zenbook Pro compatibility: These models share the same 15.48V four-cell architecture, identical BMS handshake protocol, and the same physical connector pinout — which is why one cell covers such a wide range of SKUs. Swapping a battery from an incompatible voltage rail will trigger an immediate BIOS fault, so confirm your OEM part number before ordering.
- Bench tested on actual hardware: We cycled this cell on a TUF Dash F15 platform, monitored BMS communication through the EC, and confirmed stable charge termination at 100% with no abnormal cutoff events. The BMS reported correct Wh capacity within two full cycles.
- Post-install calibration on the FX517ZE: After fitting this cell, run one full discharge to the hibernate-cutoff point, then charge uninterrupted to 100%. This forces the EC to reset its battery learn cycle and clears the inaccurate health warning that appears in MyAsus and BIOS after every cell swap.
Why the TUF Dash F15 shuts down at 20–30% after a battery swap
The FX517ZE draws sharp current spikes when the CPU and dGPU ramp simultaneously under load. If the fuel gauge IC hasn't calibrated against the new cell, it maps voltage readings from the old cell's discharge curve. At around 20–30% indicated charge, the new cell's actual voltage drops below what the EC expects for that percentage, and the EC calls an emergency shutdown rather than risk cell damage. This isn't a fault with the replacement cell — it's a calibration gap. One full discharge-to-hibernate followed by an uninterrupted full charge resolves it. After two cycles the fuel gauge IC locks onto the correct voltage curve and the shutdowns stop.
BIOS reporting "poor health" or 0% capacity on a brand-new cell
The Asus EC reads battery health data from EEPROM registers that the old cell wrote over its lifetime. When a new cell arrives, those registers haven't been populated yet, so the BIOS displays "poor health," an unknown Wh rating, or 0% on the first boot — none of that reflects the actual cell condition. Enter the BIOS, navigate to Advanced → Power Management, and run the Battery Health Charging reset if available. If not, complete two full discharge-to-hibernate and uninterrupted charge-to-100% cycles. After that the EC rewrites the EEPROM registers against the new cell and the health warning clears.
