Check your current pack

Before ordering, confirm the exact model number printed on your existing battery matches the supported list such as TP300LA-DW007H or Q302LA-BHI3T09. The connector layout and physical dimensions must align with your chassis so verify the part code on the old unit first.

Sustained discharge behaviour

The lithium-polymer chemistry delivers a steady 4 Ah output during extended work sessions rather than only in short bursts. Capacity holds up through repeated charge cycles making it reliable for daily mobile use without sudden voltage drops.

Questions about this item

Does the DS-CS-AUQ302NB arrive as a single battery or does the package include tools or cables for installation?

The DS-CS-AUQ302NB is supplied as a single Li-Polymer battery unit; no tools, cables or additional accessories are included in the box.

The listing shows many Asus model numbers — how do I confirm which version matches my laptop?

Check the original battery label for part number 0B200-00930200 or C31N1339; if either code appears, this 4 Ah black battery is the correct replacement.

What runtime can I expect from the 4 Ah rating once the battery is fitted in a ZenBook UX303?

The 4 Ah capacity restores the original factory runtime for compatible models such as the UX303UA and TP300L series; actual hours depend on screen brightness, workload and power settings.
