Do you think my iPad leaks battery acid?

I have an old iPad it's an IPad 2 (not iPad Air) and it's from like 2010 or something. I got it refurbished off the Internet and it was in great condition except for a few scrapped spots or scratches and that was like 3 years ago. The battery seems to work fine and the battery life is good but I'm nervous that since it's kinda old the battery might leak a little and maybe get on my hands or something. Would it do this or would it only do that if it gets wet or something?

What do you think of this situation and why did they do this?

There's a boy that I have had a crush on since the beginning of the school year. There was a teacher that came to the school to teach a certain class. Then when the teacher came and she wanted to know everyone in the class's names the boy that I have had a crush on since the beginning of the school was sitting next to a girl that's not pretty and I was sitting by myself. Then the teacher asked who wanted to do a favor for her and the girl that was sitting next to the boy that I have had a crush on said he wanted to do it and then the next day when the teacher asked the boy that I have had a crush on since the beginning of the school year said he wanted to do it. Then I was sitting in class and the teacher asked who wanted to take attendance using her iPad and the boy that I have had a crush on since the beginning of the school year said he wanted to do it and the teacher let him do it. Then he would walk around taking attendance and he walked towards where I was sitting and there was an empty seat next to me because the girl that sits next to me wasn't in class or was sitting somewhere else and when he walked towards me I was sitting down and he was standing up and I acted like I didn't mind and in front of the class the teacher and a girl standing next to her looked at me giving me a dirty look which is weird because at first their expression wasn't giving me a dirty look and it changed when I acted like I didn't mind that the boy I have had a crush on was standing next to me.
