The tried and true 'wet cell' is the preferred choice. All the other options are personal choices & solutions for a variety of issues not associated with the end results of starting the car and its short-term (only) storage. Remember, the storage of a car requires you to disconnect the battery, so its OEM sized battery is the choice that most makes sense (especially for the cost associated with its purchase). Spills, storage, and options added into the electrical system are all grouped into the 'what do I do about' isms. Good luck!
