Will the 36Wh 10.8V battery fit my Asus X555L without any adapter changes?

Yes, the 36Wh 10.8V unit is built to the A31N1519 form factor and is listed for the X555L, so it slides into the existing bay with no extra hardware.

How can I confirm the 3200mAh pack is charging correctly after I install it?

Power on the laptop; the OS battery icon should show a rising percentage and the firmware will report the design capacity near 36Wh once calibrated.

Does the box include the A31N1519 battery only, or are screws and tools also supplied?

The package contains the 36Wh Li-polymer battery itself; mounting screws and any opening tools are not included and must be sourced separately.
