I got a BT + [Battery Tender Plus, ~$45] initially for my BMW motorcycles. It's good for extended charging of all batteries except for the BMW AGM [Absorption Glass Mat] batteries.
While not optimal, I open the trunk, pull up the battery compartment cover, pull up the plastic battery cover [you need to unscrew the bolts on the sides] and connect the alligator clips, then leave the cover on lightly & close the trunk.
Which all works until that one day when I drove out of the garage with the tender still attached.....
