Battery Drain Issue
My Defender has under 1000 km on it , it sits for a week at a time and the battery is drained to a point where the alert is activated. I had to put it on a charger twice now. Also battery drained when I went camping for two days from just opening & closing the doors. I am thinking it’s a dud battery from the factory.

Yes, I agree a bad or poorly connected battery in the most likely cause. It is the least expensive fix, so is always the first thing to do repair-wise.
Just checking to make sure that your charger is for an AGM battery .. not a traditional lead-acid one? A lead-acid charger will destroy an AGM battery by over-charging it (been there, done that). When deeply discharged the AGM takes a while to charge .....

@Hovdebo - One thing to be aware of is that if you leave the keys in it, it's known to drain the battery. No idea why, but something is turned on when the key is in the vehicle. I know many who just leave their keys in their vehicles once they are in the garage, for instance. If you are leaving it in there, you may want to either get a faraway(sp?) cage/pouch for them or pull the keys when exiting. If you don't leave the keys in it, I'm out of ideas!

Sounds actually normal to me. Whenever a door is opened up, 20+ computers fire up. That takes a lot of juice. U can turn off interior lights by touching and holding the front upper light for 20 seconds or so. I also leave a door propped open when camping to prevent this. I put mine on a charger every month or so. I do this with all my rovers. Short trips never fully charge the battery.
At least is tells you when the battery is low instead of killing it completely.
Also, good idea to have a lithium jump pack whenever camping in case it does die. My buddies LR4 died frequently while camping.
Microstart is the best brand in my opinion but any large pack will do. Very compact and really works. I was skeptical at first but have jumped many trucks with mine.
