Verify exact model number before purchase

Check the label on your existing battery or the notebook service tag to confirm the part number matches KU531AA-TM. This pack fits a specific list of models including 6440b, 6450b, 6930b, 6530b, 6535b, 6550b, 6730b, 6735b, 6500b, 6700b, 8440p and 8440w; other EliteBook or ProBook units will not accept it.

Questions about this item

What comes inside the box and is any extra cable or adapter required?

The package contains the 6-cell lithium-ion battery itself; no additional cable or adapter is needed because the unit plugs directly into the laptop's proprietary battery bay.

How do I know this KU531AA-TM is the right capacity for my EliteBook or ProBook?

The 5100 mAh, 10.8 V specification matches the original equipment rating for every listed model including the 6440b, 6530b, 8440p and 8440w, so it replaces the factory pack without capacity mismatch.

What runtime can I expect from the 5100 mAh rating once the battery is installed?

The 5100 mAh figure restores the same charge capacity the notebook shipped with, delivering comparable run time to the original battery when the machine is used under similar workloads.
