Up to 19% off
New arrival
From $86.99 USD $106.99
Shipping calculated at checkout.
Fits Asus ROG Strix GM501GM-EI017T and 34 related models; replaces OEM C41N1727, 0B200-02900000, 4ICP7/48/70.
15.4V, 3550mAh Li-Polymer delivers 54.67Wh — matches the original pack capacity for full system load on CPU and discrete GPU.
Connector seats flush into the battery slot with single locking tab on the right side; orientation keyed to prevent reverse insertion.
We bench-tested this cell in the GM501GM platform; the BMS accepted charge without fault codes and held voltage stable under sustained 45W CPU draw.
After installation, run one full discharge to hibernate cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after every cell swap.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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

🔹 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 Strix GM501GM-EI017T — 15.4V Li-Polymer Replacement Battery (C41N1727)

This 15.4V, 3550mAh (54.67Wh) Li-Polymer battery replaces the C41N1727 cell in the Asus ROG Strix GM501 series gaming laptops. It fits the GM501GM-EI017T, GM501GM-EI007T, GM501GS-EI017T, GM501GS-XS74, and over 30 additional GM501 variants. The 4-cell configuration matches the original voltage rail and connector pinout exactly.

  • GM501 series compatibility: Every GM501 variant on the fit list shares the same 15.4V four-cell architecture, connector housing, and BMS communication protocol — so one cell works across the entire platform without modification.
  • Bench tested on actual hardware: We ran this cell on a GM501GM under sustained CPU and GPU load. The BMS held the charge curve steady through full draw cycles, with no overcurrent trip or thermal cutoff during stress testing.
  • Post-install discharge cycle: After fitting this cell, run the laptop on battery until it hibernates at cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after installation

The GM501's BIOS reads EEPROM data from the installed cell to calculate health status. When a new cell goes in, the EEPROM values don't match the BIOS's learned baseline from the old battery, so Windows and the BIOS both flag the replacement as degraded — even though it's brand new. This isn't a fault with the cell. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% rewrites the learn cycle baseline. After two to three full cycles, the BIOS health readout will normalise to reflect actual cell capacity.

Laptop shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC hasn't calibrated against the new cell's actual discharge curve. The GM501 draws hard under gaming load — full CPU plus display plus dGPU simultaneously — and if the fuel gauge IC is still referencing the old cell's voltage-to-capacity map, it misjudges the voltage cliff. The laptop shuts off before the displayed percentage reaches zero. To fix this, run two to three full discharge-to-cutoff cycles so the fuel gauge IC can build an accurate map of the new cell's voltage curve. After calibration, shutdowns at 20–30% stop and the displayed percentage tracks real remaining capacity correctly.

Frequently Asked Questions

Why does Windows show my new GM501 battery as 0% or "unknown" right after installation?

The fuel gauge IC in the GM501 reads EEPROM data from the previous cell to initialise its charge state. When a replacement cell goes in, the IC has no reference data for it and defaults to 0% or "unknown" until it completes a calibration cycle. Run the laptop on battery until it shuts down at cutoff, then charge uninterrupted to 100%. After one full cycle the fuel gauge IC picks up the new cell's voltage curve and the percentage reads correctly.

My GM501 battery stops charging at 80% and won't go higher — is the replacement cell faulty?

It's not the cell. The GM501 BIOS includes a Battery Health Charging mode that caps charge at 80% to slow cell wear during long plugged-in sessions. Check the MyASUS app or BIOS settings under Battery Health Charging — if it's set to "Balanced" or "Maximum Lifespan" mode, it will hard-stop at 80%. Switch the mode to "Full Capacity" and the charge limit lifts to 100%.

System info shows the wrong Wh rating for this battery — it doesn't match the 54.67Wh on the listing. What's happening?

The Wh figure Windows reports is pulled from the EEPROM on the cell, which stores the manufacturer's rated capacity at factory conditions. The listed 54.67Wh is the actual measured capacity at standard discharge rate — minor variation between the two figures is normal and not a sign of a faulty or mismatched cell. Confirm the cell is genuine by checking voltage under load: the GM501 battery should hold above 14.8V at moderate CPU load during the first few cycles.
