Questions about this item

How can I confirm the 11.55V 41.7Wh battery is working correctly after installation?

The system should recognise the battery immediately, show a charging icon when the 19V 4A adapter is connected, and report a design capacity close to 41.7Wh in the OS battery report.

What is included in the box and do I need to buy any tools separately?

The package contains the black 3-cell Li-ion battery and two screwdrivers, so no additional tools are required for the swap.

My original part label reads L11421-2C2 — is this the correct replacement?

Yes, L11421-2C2 appears in the compatible part-number list, so this battery matches that original.
