Cameron & Co DS-CS-AUX581NB 3.9 Ah battery

This replacement battery fits Asus ZenBook Pro Duo models including the UX581 and UX581GV series. It uses Li-Polymer chemistry and carries a 3.9 Ah capacity. The pack is finished in black and matches the original C42N1846 form factor.

Direct swap for the internal pack

The cell installs inside the chassis without extra cables or adapters. It restores mobile runtime for dual-screen workflows and frees the user from tethered operation. No external charger or docking station is required for daily use.

Replaces a depleted or failing original unit

When the factory battery no longer holds charge or reports service warnings, this unit restores full mobility. The upgrade is worthwhile once runtime drops below useful levels for portable work. Buyers needing higher capacity than 3.9 Ah or a different voltage cannot use this pack.

As a solid-state Li-Polymer pack it has no moving parts and produces no audible noise; normal warmth occurs during charge or high discharge but stays within laptop thermal limits.
