Compatible replacement battery

The Beisite C41N1906 is a new 15.4V lithium-polymer battery rated at 90Wh and 5675mAh. It replaces ASUS part numbers C41N1906 and C41N1906-1 for TUF Gaming and ROG Zephyrus Duo 15 laptops.

Decisive specification

The 15.4V 90Wh rating is the single figure that determines whether this unit matches the original power requirements of the supported ASUS models. Buyers who need a different voltage or capacity cannot use this part.

Sustained load behaviour

Lithium-polymer chemistry delivers stable voltage across the discharge cycle during extended gaming or rendering sessions. The 5675mAh cell count supports consistent runtime without the sharp voltage drop seen in lower-capacity packs.

Questions about this item

What does the 15.4V 90Wh rating mean for daily use in a TUF Gaming A15?

The 15.4V 90Wh rating matches the original specification, so the laptop will report the same capacity and charge thresholds as the factory pack.

Which connector standard does the C41N1906 use, and does it limit charge rate?

It uses the proprietary ASUS multi-pin connector used on FA506, FA706, FX506 and FX706 chassis; the connector itself does not limit the charge rate — the laptop's embedded controller manages current.

Will this battery physically fit the FA506IV and GX550LXS without modification?

Yes, the C41N1906 is a direct mechanical replacement for the listed FA506IV, FA706IU, FX506IV, FX706IU and ROG Zephyrus Duo 15 GX550LXS models.
