About this replacement
Asus ROG Station 17 PX703GE / ROG Strix GL703GE — 15.2V Li-Polymer Replacement Battery (B41N1711)
This is a 15.2V, 4050mAh (61.56Wh) Li-Polymer replacement battery for the Asus ROG Station 17 PX703GE-GC153R. It also fits the ROG Strix GL703GE-EE083T, TUF Gaming FX705DT-AU068T, TUF705GD-EW070T, and over 200 additional models sharing the B41N1711 platform. Install it when the original cell degrades and the laptop loses portability.
- ROG and TUF FX/GL703 platform fit: These models share the same 15.2V four-cell Li-Polymer rail, B41N1711 OEM part number, and identical BMS handshake protocol — which is why one cell covers the entire lineup.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and load cycles on a GL703GE. The BMS accepted the cell without fault codes, and charge termination triggered correctly at 16.8V under a standard 150W adapter.
- Post-install calibration on ROG BIOS: After fitting, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on these boards.
Why the PX703GE BIOS flags a new cell as poor health immediately after swap
The Asus BIOS reads health data from the battery's EEPROM, not from live cell measurements. The old cell writes its degraded cycle count and capacity data to that register over time. A fresh replacement cell arrives with factory EEPROM values that don't match what the BIOS expects to see, so it flags the battery as degraded or unknown. Running one full discharge-to-hibernate then a full uninterrupted charge forces the BIOS to rewrite the learn cycle data against the new cell's actual chemistry and clears the warning permanently.
Laptop shuts down hard at 20–30% charge shown on screen
This is a voltage cliff — under full CPU and display load on the GL703 or FX705 platform, draw spikes sharply and the cell voltage drops below the BMS cutoff threshold before the fuel gauge reaches 0%. The fuel gauge IC hasn't yet calibrated its internal model against the new cell's discharge curve, so the percentage shown is inaccurate. The fix is two to three full discharge-to-cutoff and full recharge cycles, which lets the fuel gauge IC map the new cell's actual voltage-to-capacity curve. After calibration, the shutdowns stop and the percentage reads accurately down to approximately 3.0V per cell.
