For owners of listed Asus models needing

It suits users whose original pack has lost runtime or no longer holds charge. Buyers with different Asus ultrabooks or other brands should look elsewhere because the connector and cell layout are model-specific. The product is not a higher-capacity upgrade and does not add features beyond the original design.

Voltage and capacity match the original 11.31V

The electrical rating determines whether the battery will communicate correctly with the laptop’s charging circuit and report accurate remaining time. A different voltage or watt-hour value would cause charging errors or sudden shutdowns. This unit replicates the factory rating exactly.

Questions about this item

Will the 3ICP7/55/90 form factor fit my ZenBook UX303UB without modification?

The 3ICP7/55/90 cell pack matches the original C31N1339 dimensions, so it slides into the UX303UB battery bay with no chassis changes.

What is the correct screw sequence when replacing the battery in a UX303LA?

Remove the nine bottom-case screws, disconnect the old pack, connect the new 11.31V 50Wh unit, then refit screws in a star pattern to avoid warping the palm rest.

How often should I calibrate the 50Wh Li-ion pack to keep capacity accurate?

Run a full charge–discharge cycle every 30 days; the onboard fuel gauge will then report remaining capacity within a few percent of the true 50Wh rating.
