Questions about this item

Does the KingSener AA-PBYN4AB battery ship with any cables or tools, or do I need to buy them separately?

The battery is supplied as a standalone unit. No cables, tools or mounting hardware are included, so nothing extra needs to be purchased for installation.

Should I choose the 45Wh or 6000mAh version of the AA-PBYN4AB for my Samsung 530U3C?

Both figures describe the same cell; 45Wh and 6000mAh are equivalent ratings at 7.4V, so there is no separate version to pick.

What does the 6000mAh rating actually deliver in a Samsung NP535U3C during everyday use?

At 7.4V the 6000mAh cell stores 45Wh, which typically powers a compatible ultrabook for several hours of mixed workloads.
