Questions about this item

How can I confirm the DS-CS-AUX31NB is working correctly after installing it in my UX31A?

The battery should charge to 100% in the OS power meter and report a design capacity close to 6800 mAh or 50.32 Wh; sustained run-time matching your previous genuine pack confirms it is functioning as intended.

What comes in the box with the DS-CS-AUX31NB and what must I source separately?

The package contains only the 7.4 V 6800 mAh Li-Polymer battery measuring 317.00 x 131.92 x 7.90 mm; you will need to reuse your existing screws and any thermal pads or connectors from the old battery.

Which capacity version of the DS-CS-AUX31NB should I choose for a Zenbook UX31E-RY009V?

This model is offered in a single 7.4 V 6800 mAh (50.32 Wh) Li-Polymer variant, which matches the original C22-UX31 specification for all listed UX31, UX31A and UX31E sub-models.
