Cameron & Co DS-CS-AUX330NB laptop battery 4.5 Ah Li-Polymer Black

Replacement battery for Asus ZenBook UX330 series

This Cameron Sino DS-CS-AUX330NB is a new 4.5 Ah lithium-polymer pack built for Asus ZenBook UX330, UX330C, UX330CA and UX330CAK ultraportables. It matches the original 0B200-02090100 and C31N1610 part numbers and delivers 11.55 V at 51.98 Wh in a black 307.72 x 135.34 x 2.92 mm form factor. Owners of compatible ZenBook models can swap the depleted cell without adapters or firmware changes.

Direct swap for worn 0B200-02090100

The pack replaces the factory battery when runtime has dropped or the laptop only runs on mains power. It restores the original capacity without requiring a higher-wattage charger or a BIOS update. The upgrade is worthwhile when the existing cell no longer holds a useful charge but the notebook itself still meets daily workload demands.

Steady output during long unplugged sessions

Li-Polymer chemistry maintains a stable 11.55 V through the discharge curve, so the ultrabook does not throttle abruptly as the charge falls. The slim 2.92 mm profile fits the original chassis without bending the palm rest or stressing the trackpad cable. Thermal behaviour stays consistent across repeated full cycles, avoiding the sudden shutdowns seen with aged cells.
