As of Jan 2018, the battery adhesive strips are not in the parts list above. (Maybe they were at one time, but are no longer available?) I used some very small 3M Command hook adhesive strips instead.

Will the device boot up with no error message after replacing it with new battery? Or do you need some programming before or after replacing it?

There is no error when battery is changed.

Just successfully changed my battery without any issue. Booted up normally and able to do everything I was able to do before.

Thank you for the awesome guide :)

The Sony Experia Z5 Compact is water and dust proof. Will heating the back after putting it back on reseal the phone - or is there another step that needs to be added?

Pretty annoying, this mentions NOTHING about the battery adhesive strips to order separately, and neither of the “things to buy” come with them. I just replaced my battery, but it’s just flopping around inside at the moment. Where do I order the battery adhesive strips to adhere the battery to the motherboard? Note for others doing this too, you NEED the adhesive strips separately beside the battery and the back adhesive!

Yeah I ran into the same issue, I found them at https://www.teknikdelar.se/mobilreservde... but that's a Swedish company I think. I made a suggested edit to this post, suggesting the need for strips to be at least mentioned but I got a reply of “just use some tape".
