Lots of late model vehicles have relatively high standing "drains" or loads on the electrical system, things like security, navigation, stereo's, the main dash screens etc which all combine to create a significant load even when the vehicle is off.
Two weeks is about the maximum they can sit before they won't start in lots of cases.
I drove a mid size bus for a school that drained a bit when sitting, it had two N50ZZ in series for 24v and if you left it for a fortnight over the school hols it wouldn't start. Used to have to take it for a run every week to keep the batteries topped up. Did it right from brand new and the dealer reckoned it was normal, an autolecky checked it over and gave it a clean bill of health as
well.

Forgot to add a mate has a XR6 turbo and he puts a trickle charge on it if it isn't going to be driven for more than a week as it flattens the battery over about a fortnight.

Have also got an XR6 Turbo, battery goes flat regularly if it's not recharged every 3-4 weeks.

G'day Chris.
A short wouldn't do that as a short is a short and carries high current usually.
Seeing you asked the question, I would like to know how you determined the current drain as most people wouldn't normally be able to find that?
I don't know what is a normal standing drain for an XR6, but if it has only recently become a problem I would look at the following items.
Does the boot light turn off when boot is closed??? Problem may be a faulty switch on lock mechanism. Not so much faulty but simply not "switch opened" to shut off the boot light globe.
Not knowing the alternator condition it is possible the alternator has a diode which leaks a small amount of current through it's rectifier and that drains the battery prematurely. Also the regulator, depending on type can do the same. A flow
check between charge cable to alt terminal may show some backflow. Same for the regulator wires. We rely heavily on very small pieces of silicon in diodes and IC's to be correct all the time.
Have you had any additional 12v gear fitted recently, ie, around the time the fault was noticed?? Sometimes people add items which connect to wires and it turns on a small relay and it's coil drain is approx what you say is happening.
If the flow is still there, you may be able to sequentially remove one fuse at a time to see which circuit is the culprit and then look at those 12v components each in turn.

Thanks guys
I had the battery checked by super cheap and auto
barn both read 12.7
RMD I turn off everything in the car . and put a multi meater between the earth strap and its terminal.

.
A "multi MEATER" ???
Will that measure the voltage on an "earth STEAK" ??? LOL

Hi Allan,
No mate you got that wrong. A multi MEATER is a good ole fashioned mixed grill !!!
