6 volt Batteries split at the corners
...sometime this winter. I'm not sure what the hell happened or why, but they both split on the four corners and leaked the water out. Any suggestions as to why? They were out in the weather hooked up...

Sorry to hear of your dilemma, a fully or nearly fully charged battery will resist freezing, but when they are significantly discharged they are susceptible to freezing which appears to be the scenario you described. We have always left our batteries on our rig during the winter enduring many cold fronts delivering sub-zero temps, but our rig is stored in our backyard and is always plugged in allowing our smart converter to keep them fully charged. It's an unfortunate circumstance, Samsclub/Costco is where we purchase our replacement batteries as they always have the best prices in town.
