The battery of my Samsung Galaxy Book NP750XDA-KDEIT doesn't hold a charge anymore so I wanted to replace it.

Initially I ordered the first compatible battery I could find on Amazon, and I purchased one with model AA-PBSN4AF. When I installed it, the battery wouldn't charge, and later I found out on this website that this particular model was not compatible.

So, I then purchased the correct model, AA-PBSN4AT on AliExpress (I couldn't find it available anywhere else that ships to Italy) and I can see on the back that the text is exactly the same as the original one, except...
