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 ROG SCAR II GL504GW-ES043T — 15.4V Li-Polymer Replacement Battery (C41N1731)
This is a 15.4V, 4300mAh (66.22Wh) Li-Polymer cell built to the C41N1731 specification. It fits the Asus ROG SCAR II GL504GW-ES043T and a wide range of ROG Strix GL504 and G715 variants. The four-cell configuration matches the original voltage rail exactly — no adapter or modification needed.
- GL504 and G715 platform compatibility: These models share the same 15.4V four-cell bus, C41N1731 part number, and identical connector pinout. The BMS handshake protocol is consistent across GL504GW, GL504GS, G715GW, and G715GV variants, so one cell spec covers the entire platform without firmware conflicts.
- Bench tested on actual hardware: We ran this cell on a GL504GW unit and monitored BMS communication across charge and discharge cycles. The protection circuit engaged correctly at low-voltage cutoff, and the charge controller accepted the cell without throwing an unrecognised-battery flag.
- Post-install discharge cycle on ROG SCAR II: After fitting this cell, run one full discharge until Windows hibernates, then charge uninterrupted to 100% without waking the system. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after installation
The ROG SCAR II BIOS reads health data from the outgoing cell's EEPROM and carries that degraded profile into the new session. The replacement cell has no stored cycle history, so the firmware interprets the mismatch as a fault. Running the full discharge-to-hibernate then uninterrupted charge sequence lets the fuel gauge IC write a clean baseline to EEPROM. After one or two complete cycles, the BIOS health indicator normalises and reflects the actual cell condition.
Laptop shutting down at 20–30% shown after battery swap
This is a voltage cliff problem, not a capacity problem. Under full CPU plus display load on the GL504GW, the power draw spikes sharply — if the fuel gauge IC still holds calibration data from the old, degraded cell, it underestimates how quickly voltage drops under that load. The system hits hardware undervoltage cutoff before the displayed percentage reaches zero. Run two complete calibration cycles — full discharge to hibernate-cutoff, then a full uninterrupted charge to 100% each time — so the fuel gauge IC maps actual voltage curves against the new cell at 15.4V nominal.

Frequently Asked Questions
Windows is showing my new battery as "0% available (plugged in, charging)" and it's been two hours — is the cell dead?
The fuel gauge IC carried calibration data from the old cell into the new session, and the readings are meaningless until the IC maps the new cell's voltage curve. Plug in, let it charge uninterrupted to 100%, then run a full discharge to hibernate-cutoff without interrupting it. After that first complete cycle, the percentage display on most GL504GW units corrects itself within one additional charge.
The MyASUS app is showing a different Wh rating than the original battery — should I be worried?
The Wh figure displayed in MyASUS pulls from the EEPROM on the previous cell and may still reference the old cell's rated or degraded value rather than the replacement's actual 66.22Wh spec. This is an EEPROM data mismatch, not a fault with the new cell. Run the BIOS battery learn cycle — one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% — and the reported Wh value will update to reflect the installed cell.
My GL504GW charges to 100% normally but the BIOS health screen still says "Battery health: Poor" after a week of use — what's wrong?
The BIOS health status on this platform is slow to update because it cross-references cycle count and capacity data stored in the cell's EEPROM against its own learned baseline. If the learn cycle hasn't completed cleanly, the health flag persists. Enter the BIOS, navigate to Battery Health Charging, set the limit to 100% (not Balanced or Full Capacity mode), then complete two full discharge-to-hibernate and uninterrupted charge cycles. Check the health screen again after the second cycle — it should clear at that point.
