Battery storage

Storing 3 batteries for the winter. One is a deep cell for the trailer, and two are maintainability free from the truck. All are 12 volt. My question is, can I connect them all together, pos to pos and neg to neg, and put the battery tender on to keep all three charged?

    Yes, that is what I do.
