About this replacement
Asus ROG Strix GL703GM Scar Edition — 15.4V Li-Polymer Replacement Battery (C41N1716)
This is a 15.4V, 4800mAh (73.92Wh) Li-Polymer battery for the Asus ROG Strix GL703GM Scar Edition and GL703GM gaming laptops. It replaces OEM part C41N1716 and fits the four-cell configuration used across the GL703GM platform. Install it when the original cell no longer holds charge or causes unexpected shutdowns under load.
- GL703GM platform fit: The GL703GM and ROG STRIX S7BS8750 variants share the same 15.4V four-cell bus, connector pinout, and BMS handshake protocol — one cell covers the full range without modification.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a GL703GM unit. The BMS negotiated correctly, charge termination triggered at 16.8V, and the protection circuit tripped cleanly on a simulated over-discharge test.
- Post-install calibration on GL703GM: After fitting, run the laptop down to hibernate cutoff under real load — gaming or a sustained CPU stress test works — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.
Why the GL703GM shuts down at 20–30% battery remaining after a cell swap
The GL703GM's fuel gauge IC builds a discharge model around the original cell's chemistry profile stored in EEPROM. A new cell has a different actual voltage curve, so the IC misjudges the remaining charge and calls shutdown too early. This is not a fault with the replacement cell — it is a calibration gap between the new chemistry and the old model. Run two to three full discharge-to-hibernate, then charge-to-100% cycles, and the fuel gauge IC recalibrates to the new cell's actual voltage floor.
BIOS reports battery health as "poor" or "replace" immediately after installation
The BIOS pulls health data from the battery's EEPROM, which on a new cell shows zero charge cycles completed and may flag a mismatch against the previous cell's wear history. This triggers a false health warning — the cell itself is new, not degraded. Boot into the BIOS battery care settings and confirm charge mode is set to full capacity, not battery health mode. Complete one full learn cycle (full discharge to hibernate, uninterrupted charge to 100%) and the health flag clears on the next boot.
