Past couple of years I didn't remove the sealed battery from the lawn
tractor which is kept in a detached garage. Winter temp in the garage
never dropped to 32F due to mild winters. There were no problems the

period, does this necessarily cause irreparable damage to the battery?

That's an acid solution in there, not water alone...freezing temp is
_well_ below 0F.
