Questions about this item

Does the 6-cell 4400 mAh unit ship with any tools or cables, or must I buy them separately?

The battery is a direct replacement for the original Samsung pack; no extra tools or cables are required for installation.

My original battery is marked AA-PB9NC6W — is the 11.1 V 4400 mAh version the correct match?

Yes, AA-PB9NC6W appears in the compatibility list, so this 11.1 V 4400 mAh 6-cell unit is the right choice.

What does the 49 Wh rating mean for daily run-time on a Samsung NP300E?

The 49 Wh capacity restores the factory run-time spec for the NP300E, giving roughly the same hours per charge as the original battery.
