Is there enough room to lift one up on top of the other to allow the lower one to slide out? Then once the lower one is out the top one would take the position of the removed one and that slides out too. There has to be a way to get them in and out without destruction of the container and door. You may need a thin piece of wood to lay on top of the one battery as it is holding up the other battery, or two people with one holding the one battery so the other gets slid out? Without seeing or having photos this is just a guess.
