Thank you!

Didn’t need the entire teardown, just the batter Watt-hour and general shape to make sure I am buying the correct thing.

Keep up the great work for the community.

It would also be helpful if you included the specification of the screws. For example, if you buy one without a battery.

Dell's website says this laptop should take a KG7VF battery but this guide says to use a F3YGT battery? Why?

I found out why. KG7VF and F3YGT refer to the same item. F3YGT is what is physically printed on the battery while KG7VF is what it's called on Dell's store. Very interesting procedure there Dell.
