Does replacing the battery could cause a short circuit for motherboard

Hi guys I am very sorry for bothering you guys, I just want to ask about battery replacement.

So I live in Indonesia where they sell only the 4g version of the note 20 ultra (SM-N985F/DS). However, I got myself a note 20 ultra 5G (SM-N986B) from Singapore. Lately, I have been trying to replace my battery since it's in bad condition. So I went to a local samsung service center. At first, I was accepted since my device can use the same battery as the local note 20 ultra's battery.

However, later on, the technician called me and explained that replacing the battery with the local one might cause some issue. The technician mention about something about the different pins in the motherboard between the 2 phones (I dont really understand).

So based on that, I decided to cancel the reparation. Yet recently, I found out that both device actually use the same battery model, which is EB-BN985ABY. Thus, I am confused, does switching the battery between the 4G and the 5G version could actually cause some problem ? Can any of guys help me understand this problem?

(ps. Sorry for my grammar mistakes, english is my second language)

Here is the battery I am currenty buying, almost all websites said that it was suitable for my note20 ultra 5g.

And here is the battery used by the local note20 ultra 4g. As you can see they are identical.
