Because you damaged them.
When you short out a cell, the instantaneous, insanely high, amp draw causes the normally stable chemicals in the cell to become...less stable. The chemical reaction that causes batteries to work gets thrown all out of whack from the high rate of speed it's asked to perform at. Hydrogen gets pushed out of the molecules into bubbles that form inside the cells, preventing the reaction from happening at an efficient rate in the future. If the pressue form those bubbles gets to great, your cells will outgas some of it. Maybe not enough for you to notice goo at the end of your cells, but even with just the internal bubbles, your packs will have less voltage and less runtime because the chemistry no longer has access to some of it's hydrogen. It may seem
to have more 'punch', but I'd be willing to bet if you threw those cells on a TurboMatcher for a few cycles, you'd find out that you'd hurt them.
