Replacement battery for Asus U-series laptops
This lithium-ion cell pack fits Asus U20, U30, U50, U80, U81 and U89 models, matching part numbers such as A31-U80 and A32-U50. It is built for owners who need a direct swap for an ageing original battery without modifying the chassis. Buyers whose laptops use a different form factor or voltage cannot use this unit.
4.4 Ah capacity at 11.1 V for daily workloads
The 4400 mAh rating delivers several hours of typical office use, web browsing or video playback on a single charge. Runtime shortens under heavy multi-tasking, discrete graphics loads or when the screen brightness is kept at maximum. The pack does not support fast-charging protocols beyond the laptop’s standard circuitry.
Black housing with OEM-compatible connectors
The 206 x 47 x 30 mm black casing aligns with the original battery bay and locks using the stock latches. No extra cables, tools or driver discs are included in the package. Installers simply remove the old pack, snap this one in place and let the system calibrate on first use.

How can I confirm the battery is recognised correctly after installation?

Does the package include a charger or only the battery itself?
Only the black 206.00 x 47.00 x 30.00 mm battery is supplied; an AC adapter must be purchased separately.
