Replacement Battery for ASUS TUF and ROG Models

This 15.4V lithium-ion pack replaces part numbers C41N1906 and C41N1906-1. It fits TUF Gaming A15, F15 and A17 chassis as well as ROG Zephyrus Duo 15 GX550 series laptops. The black Type B unit is designed for owners of the listed models who need a direct swap for a depleted original battery.

Capacity and Chemistry Constraints

Rated at 90W and 5675mAh, the cell uses lithium-polymer chemistry at 15.4V. That energy level is fixed by the form factor and voltage, so runtime will match the original specification rather than extend it. Users needing longer unplugged time must carry a second pack or use external power.

Build and Daily Handling

The black casing aligns with the internal mounting points of the compatible ASUS chassis. No tools beyond a standard screwdriver are typically required for the swap. The pack is not a universal fit; it will not work in laptops outside the listed FA506, FX506, FA706, FX706 or GX550 families.

Questions about this item

Which capacity version of the C41N1906-1 battery should I choose for my ASUS TUF Gaming A15 FA506IV?

This replacement battery is offered in a single 90W (5675mAh) capacity at 15.4V, matching the original C41N1906 and C41N1906-1 part numbers for the listed models.

What does the 90W rating mean for actual runtime in my laptop?

The 90W (5675mAh) rating indicates the total energy the pack stores; real-world runtime depends on your specific model's power draw, screen brightness, and workload, but it restores the factory capacity for compatible FA506, FX506, and FA706 series machines.

What connector interface does the C41N1906-1 use and what does it limit?

The battery uses the proprietary ASUS multi-pin connector built into the C41N1906-1 casing; it fits only the listed TUF Gaming A15, F15, A17, and ROG Zephyrus Duo 15 models that accept part numbers C41N1906 or 4ICP5/63/133.
