I was confused by this as well, but I later understood that this card (nid:1516558389219) talks about a regular battery, vs the other card (nid:1516558157624) which talks about a button battery
This is a button battery This is a regular battery
I hope I made this clear on the image:
It still needs to be approved

We can make it clearer on the card and/or the image, if needed
