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 ZenBook 15 UX533FD — 15.4V Li-Polymer Replacement Battery (C41N1814)
This is a 15.4V, 4700mAh (72.38Wh) Li-Polymer battery for the Asus ZenBook 15 UX533FD and UX533 series notebooks. It replaces OEM part numbers C41N1814, C41PpEH, and 0B200-03120100. The battery slots into the UX533FD chassis and connects to the same 4-cell battery management circuit the original cell uses.
- UX533 series compatibility: The UX533FD, UX533FDA, and their retail variants all share the same 15.4V four-cell battery bay, connector pinout, and BMS handshake protocol. That common architecture is why one cell part number covers the full range.
- Bench tested on actual hardware: We cycled this cell through charge, full-load discharge, and BMS communication checks on a ZenBook 15 board. The protection circuit tripped correctly at low-voltage cutoff and the charge IC resumed without fault codes.
- Post-install discharge cycle: After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity curve and clears the inaccurate health warning that appears after every cell swap.
Why the ZenBook 15 shuts down at 20–30% after a battery swap
The fuel gauge IC inside the UX533FD stores a learned discharge curve from the previous cell. When a new cell goes in, the IC still uses that old curve to estimate remaining capacity. Under full CPU and display load, actual cell voltage drops faster than the stale model predicts — the laptop hits the hardware low-voltage cutoff while the OS still shows 20–30% remaining. Running two or three complete discharge-to-hibernate, charge-to-full cycles forces the fuel gauge to rebuild its model against the new cell's real voltage behaviour. After calibration, the shutdowns stop and the percentage readout tracks accurately.
BIOS reporting battery health as poor immediately after replacement
The BIOS reads battery health data from an EEPROM register that the old cell wrote to over its lifetime. A fresh cell arrives with either blank or factory-default EEPROM values, which the BIOS interprets as a degraded or unknown battery. This is a data mismatch — not a fault with the new cell. Complete the full discharge-then-charge calibration cycle described above. After one to two full cycles, the BIOS battery health indicator updates to reflect the new cell's actual state and the poor-health flag clears.

Frequently Asked Questions
My ZenBook 15 shows the wrong Wh rating in Windows Battery Report after fitting the new C41N1814 — is the cell undersized?
No — the Wh value shown in Windows Battery Report pulls from the EEPROM data embedded in the battery, and a replacement cell may carry a factory-default or slightly different rated figure than the original. The actual usable energy delivered by a 4700mAh, 15.4V cell is 72.38Wh regardless of what the EEPROM reports. Run one full calibration cycle — discharge to hibernate cutoff, then charge uninterrupted to 100% — and the reported design capacity will align with the new cell's chemistry.
The fuel gauge on my UX533FD is jumping around — showing 60%, then 45%, then back to 55% within minutes of unplugging. What's wrong?
The fuel gauge IC on the ZenBook 15 board uses a learned discharge model built up over hundreds of cycles on the original cell. After a cell swap, that model no longer matches the new cell's voltage curve, so the percentage readout swings erratically as actual voltage diverges from the stored prediction. This settles after two to three complete discharge-to-hibernate, charge-to-full cycles that let the IC recalibrate against the new chemistry. Do not interrupt the charge during calibration cycles — stop at hibernate cutoff each time and let the charger reach 100% before unplugging.
Charge stops at exactly 80% on my ZenBook 15 and won't go higher — is the replacement battery faulty?
This is almost always a BIOS charge-limit setting, not a battery fault. Asus notebooks running MyASUS or certain BIOS versions ship with Battery Care Mode enabled, which caps charging at 80% to reduce long-term cell stress. Open the MyASUS app, go to Customization → Battery Health Charging, and switch the mode from Balanced to Full Capacity. If MyASUS is not installed, enter the BIOS at startup, navigate to Advanced → Battery Health Charging, and disable the limit there.
