Questions about this item

How do I install the K5XWW 60Wh battery in my Dell Latitude 7389 2-in-1 and which step is often missed?

Power off the laptop, remove the base screws, disconnect the old battery cable before lifting it out, connect the new 7.6V pack, then replace the cover; the step people skip is unplugging the old cable first.

What maintenance or replacement will this 60Wh Li-polymer battery need over time?

The pack is rated for up to 500 recharge cycles; after that capacity drops and a replacement battery will be required.
