Default Unusual way to kill a battery but why wouldn't it jump start?

Since we bought our Chevrolet Bolt electric, the 9-4X just sits in the garage. We had a spell of single digit temperature cold weather and afterward, the 9-4X wouldn't start; obviously a dead battery. I put the charger on it to no effect. Upon removal, it was obvious what had happened. The back end of the battery case was bulged out. Evidently being discharged changes the chemistry enough so the electrolyte froze and broke the case and most likely the battery internals as well.

I know well a seldom-used battery should be on a trickle charger/battery maintainer, but I just got lazy and didn't do it.

I tried jump starting and even with the bad battery removed, the starter wasn't being engaged. What about this requires special handling for a dead battery?
