Questions about this item

Does the GT6TK battery ship with installation tools or cables, or do I need to buy anything else?

The battery is supplied as a standalone unit; no tools, cables or additional parts are included in the package.

Should I choose the GT6TK or MWK05 part number for my Latitude 9440 2-in-1?

Both part numbers refer to the same 11.55V 5065mAh battery and are interchangeable for the Latitude 9440 2-in-1 and 9450 2-in-1.

What does the 11.55V 5065mAh rating mean for daily runtime on a Latitude 9450 2-in-1?

The 11.55V 5065mAh capacity matches the original specification, so runtime will be comparable to the factory battery when new.
