What drains the battery more?

[RNajarian]

My 2005 955 is a regular Garage Queen. Safe secure in the locked garage behind a gate I don’t need to lock the doors. The car is driven maybe once every 3-4 weeks.

What drains the battery more? Leaving is locked or unlocked?

I read somewhere that locking the vehicle drains less energy from the battery than leaving it unlocked.

Thanks

Locked activates the interior motion sense. (somewhat draining) - that can be shut off with a quick press shortly after locking.

Unlocked should be minimal drain.

That’s what I was thinking. I normally park it unlocked, and the batteries in my Cayenne last about 8 years.

I leave mine on a battery tender if I am not driving it for a week or two. The same with the 911s.

Locking many vehicles shuts down most of the onboard small computers.
