If there was any open space inside the box, the batteries did that to the box and each other when they moved around. Judging by that picture, it looks like you didn't properly package your batteries.

When shipping, the boxes do not stay upright. You should expect them to have a 10 foot drop. Expect these things and pack accordingly. When we shipped computer battery backups at a previous job, we cut down boxes to fit exactly over the retail box, like wrapping a christmas present.
