Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions
My TUF Dash F15 shows the battery Wh as 0 or completely wrong in Windows after I fitted the new cell — is the battery faulty?
The Wh figure Windows displays is read directly from the EEPROM on the battery's BMS, and a new cell ships with those registers either blank or set to factory defaults that don't match your system's logged history. This isn't a fault — it's an uninitialised data field. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% each time. After the second cycle the EC recalculates and writes the correct Wh figure, typically 71–72Wh on this cell.
The charge stops at exactly 80% and won't go higher — did I get a defective battery?
This is almost always the BIOS-level charge limit in Asus Battery Health Charging mode, not a battery fault. Open MyAsus, go to Customization → Battery Health Charging, and check whether "Balanced Mode" or "Maximum Lifespan Mode" is active — both cap charge below 100%. Switch to "Full Capacity Mode" and plug the laptop in again. The cell will charge to 100% within the next charge cycle.
The fuel gauge is jumping around — it reads 60%, then drops to 35% two minutes later without heavy use. What's causing it?
The fuel gauge IC on the FX517ZE calibrates its state-of-charge model against the cell's discharge curve over the first few cycles. With a new cell installed, the IC is still using the voltage-to-capacity mapping it built for the old, degraded cell — so readings are erratic until it relearns. Let the battery discharge fully to hibernate-cutoff, then charge uninterrupted to 100%, and repeat once more. After two complete cycles the fuel gauge IC locks onto the new cell's curve and the readings stabilise.
