I my experience, this is by far the best way to maintain batteries that are not in use for long periods of time.Quote:

With solar, the battery is allowed to settle ( rest ) at night.
BTW, up to a 10w solar panel can be used, with out a regulator.
I can't drive at the moment and my D4 has been sitting in the garage for a weeknight so
I have the Traxide dual battery
When I went to get in the car today I got the message low bsttery please start the car
The car started ok
But why the message

the internal temp monitoring isnt for the battery, its for the device itself.

Hi Rich and the voltage level for the warning is set at 12.2v, while my isolator cuts out at 12.0v but your D4 can be started from a battery with 11.58v.Quote:

BTW, if any landy is a daily town drive vehicle, you will be surprised how many have a voltage level of around 12.2v to 12.4v.
For those with the inclination, try measuring your cranking battery voltage in the morning, before you start your motor.
Again, many of you may be a bit surprised at how low your cranking batteries are.
I was a bit surprised I got that message after a week or so. Any way it it is on the charger tonight. I have one of those CTEK 5 amp ones.Quote:

It would be good to know what is drawing on the battery when it is All locked up and close down though.
My accessories are
traxide dual battery, I think the 4s set up
linear electronics LED gizmo to cater for LED lights in trailers
Tekonsha P3 brake controller
Could the installation of one of these cause some extra draw on the batteries.

What kind of charger was it eevo ?
Yes, that's what I summarised from Cteks claims in my earlier post.Quote:

The higher amp models (15a and up) have a battery temp monitor.
Thanks Tim.Quote:

Tim,
If you use a timer to turn the charger on off, you could simulate the same as the solar charging as you mentioned above.

Forum rules say I can't cant answer that.Quote:

Hi All, just closing the loop on this thread that I started.
In the end, I did nothing (parked the Disco in the carport and turned the ignition off), came back 24 days later and it started first press without any hesitation - as did the Passat.
I don't know if that proves anything but at least the answer is here for the next punter that comes along!
Cheers

It proves a lot. It proves that your battery/s are in good nick.Quote:

By how much in your case I do not know. It could be a few days, weeks or some months.
Because of the unknown here, is the reason why I would have put a charger on it for the length of time you were parked.
At the very least I would have disconnected them, as you would have also had a parastatic drain.
If you do this again down the track when they are a little older, you might find that it wont start.
