My batteries (2) have always been very difficult to remove. They are quite tight when installing, after the electric contacts begin to seat. It takes much effort to get the battery to move when trying to extract, and is difficult until the electric contacts clear their seats. Not sure just where the tightness is.
I too thought it was the contacts that makes it hard to remove, but I don't think so, now. If you watch the battery go in, the upper part of the compartment, in the center, has a thin projection that the top of the battery latch catches behind. Even after releasing the latches, that projection still makes contact with the smooth, flat part of the battery. Because it's thin, I think it may be binding by trying to follow the battery, out. At least, that's the way it looks to me.
