yep, the bat has a drain on it just like any other "newer" car. This make has extra.
If the car sits, for more than a couple day, put a trickle or maintenance charger
on it.
IF camping look into a "solar" powered charger, usually available at RV dealers.
Know of a few people who say it works ! they have campers / motorhomes.
One neighbor parks his Mercedes for weeks while out on his boat, applies a solar charger
and it starts every time on a strong battery.
