Questions about this item

Will the 14.8V 40Wh XCMRD battery fit alongside the original Dell AC adapter I kept from my Inspiron 15 3521?

Yes, the battery matches the 14.8V 40Wh specification used by the Inspiron 15 3521 and other listed models, so your existing Dell AC adapter will charge it normally.

How can I verify the 4-cell lithium-ion pack is working correctly after installation?

The laptop should recognise the battery immediately, show 14.8V in the BIOS or OS power meter, and report a design capacity near 40Wh with normal charge and discharge behaviour.

Does the package include only the 10.72 x 1.82 x 0.79 inch battery, or are screws and tools also supplied?

Only the 4-cell XCMRD battery is included; mounting screws and any opening tools must be sourced separately.
