LR4 Low voltage, new battery, 2016 S

Last week I found my battery dead. I started with cables and booster together.
Battery fully charged at the workshop, but the next morning, low battery again.
Wend to the dealer and got brand new battery, fully charged.
next morning - again low battery!
Charging is good.
Radio is Off, AC is OFF, Lights is OFF.
What can be consuming the battery over night?

That’s a big drain...
Glovebox light or something like that, or a chafed wire going to earth.

Cubby box fridge is on!
 It can when others can't,
It will when others won't,
It goes where others don't.

Rocker switch under the lid.

It will when others won't,
It goes where others don't.

You have quiescent drain. Have you had a fuse pop recently?

One of the modules or electrical items in the car is continuing to draw current. Once you’ve ruled out the obvious of lights on etc. You need to look at the drain

I had an issue (well still have) that turned out to be the camera module. I had a feeling it was as I had a battery blow a cell and blow the fuse for the cameras. I put a new one in thinking that was all it needed but I then had a quiescent drain until I pulled the fuse.

I confirmed it by disconnecting the battery and placing my fluke in series and watching the current draw. When the car went to sleep the current draw dropped but there was still a significant amount. After pulling the fuse the draw fell dramatically.

If your handy with electrics, search the forum for quiescent drain as I think Robbie wrote an article or how to.

The problem was not the battery, but it was voltage unit t the terminal, wit very little corrosion, that led to a different voltage on the unit.
Good cleaning solved the problem.
Thank to you guys.
