Question about new MacBook Air battery from ifixit

Hello,

just received a new battery from the the ifixit EU store and it came with transparent plastic tabs on each individual part of the battery (that is in addition to the transparent plastic packaging of the whole battery). Don't know if links are allowed, but here is a picture I got off google with the same kind of transparent cover, so you can get the idea:

My question is - do I leave those on when installing the battery, or I should peel them off. They seem to be attached quite firmly, making me think they should stay on...any advice is appreciated :)
