Reducing battery consumption when camping with your l322

Spent last week camping in Alpe d'Huez in the French Alps while competing in a mountain bike race and the car was parked in a field without being moved for about five days. However, I was constantly unlocking and locking the car to take gear in and out mornings and evenings (my tent attached to the side of the car - see photo). On Friday afternoon the boot wouldn't open and then I realised the car wouldn't start. Flat battery.

Luckily I was able to borrow some jump leads and get the car started after about 25 minutes of charging from a friend's car. I didn't think about how much power each unlock, door open, door close and lock cycle was consuming. It got me wondering if there are any ways you can reduce the amount of power accessing the vehicle consumes.

I've since learned that you can disable the interior lights by holding the central interior light switch until it flashes, which is a good start (assuming you have another light source when accessing the vehicle at night). However unlocking the car still powers up the binnacle display and also the central touch screen and these remain on for a short while after locking the vehicle. Is there any way to unlock and open the vehicle and close it again without all the computers etc. from powering up?

Any other tips for reducing the battery consumption when you aren't planning on moving the vehicle for while but still need to access it? I'd be interested in any tips L322 campers can offer Smile

Mains outlet and battery charger ?
Take along a second battery or fit a dual battery setup ?
Start it and leave running for a while every few days ?

I had the DBPower 600A battery charger with me but it didn't succeed in starting the car which is why I resorted to the jump start. The field I was camping on was only used for camping for the week of the event I was attending so it had not mains or water supply. I could have started the car every few days but it's a bit annoying for the other campers. I was hoping there might be some secret way of accessing the car without everything coming online Laughing

Of course, I could have simply unloaded everything into the tent but the car is obviously more secure when your camping spot is not occupied during the day. 2012 Vogue 4.4 TDV8 automatic (LHD), Santorini Black

You can fit a temporary second battery in the boot connected to the rear fuseboard and disconnect the negative terminal from the front battery during your stay.

When the front battery is disconnected it will retain its full charge so that when you want to start the car all you do is reconnect the terminal and away you go. Even easier if you fit a battery isolating switch to the front battery.
When you have the front battery disconnected the second battery will quite happily keep the car operating, just make sure your drivers door can be opened by key if you happen to discharge the second battery.

If the second battery does discharge all you have to do is leave it connected, start the car via the front battery and go for a run to recharge it.
You can connect the second temporary battery by Anderson plugs, crocodile clips etc.

This arrangement also works for those leaving their cars in airport carparks for extended periods and guarantees the car will start when required. Thumbs Up I haven't lost my marbles, they're in a bag somewhere

If I understand correctly what I've been reading in other forum battery related posts & from my own recent experience with our car, a major issue with the RR is that many electrical systems in the car take at least 20 minutes to shut off after locking the car.
So the electrical consumption is much higher than you might think if the car is locked / unlocked a few times - especially if there's an interval of more than 20 minutes between them.
Leaving the car unlocked, seems to be even worse. I've twice flattened the battery over what was as little as 6 hours when working on the car while leaving it unlocked.
The car appears to hold it's charge fine /re-start OK for more than 3 days - when left locked.
( I'm assuming this indicates no major electrical system drain issues.)

The message appears to be to keep the car locked & unlock as few times as possible - unless the engine is re-started to re-charge the battery. Paul,

you could get a solar charger and put it on the roof and wired directly the battery for the duration. Thumbs Up

that would trickle charge the battery while you are camping. need a fairly big charger though. There is nothing that can't be fixed with a hammer😜😜

Solar panels connected to the main battery - although there doesn't appear to be a lot of sun in your pic.

Would they be safe or stolen if you left them connected while away from the campsite?

My panels. Hmm, pix significantly degraded when uploaded.
