Oh, and last year I was away for three and a half months and my D4 started fine when I got back. So I don't think the problem is with the car itself.

My D4 can be parked up for a month or more at a time and found that even with the DBS the cranking battery can get quite low. I put a switch in the isolator for two reasons; one to reduce the quiescent battery drain; and two leave me with a charged second battery so I can jump start myself if needed.
The switch just goes in the ground wire for the isolator.
Andy - I suggest you leave your bonnet closed and monitor the battery voltage from pins 3 & 4 on the 12S (white) tow socket. (3 is ground and 4 is permanent power from your battery).
Note there will be a minor voltage drop at the socket - compared to what is at the terminals, due to the ~4m of cable run.
Cheers,
Rob
I bought a Ctek to 12S converter plug from the Disco UK site, it lets me leave the car locked in my complex and the charger locked in the car.Quote:

Hi Silenceisgolden, as of two years ago, only the standard SC80 draws that sort of current.
The new SC80-CB and all SC80-LR have been made with low current drawing relays and actually draw less than 200ma.
The USI-160 draw about 140ma.
The USI-160, the DT90 and the ABG-25 all have the TIME-OUT feature which demonically reduces the amount of battery consumption for vehicle not used regularly and the SC80-CB and SC80 will have this feature added in the not to distant future.
If anyone is not using their vehicles regularly, then a small current capacity switch can be fitted in the earth wire coming from the SC80 and this can be used to turn the SC80 off when the vehicle is not going to be used for some period of time.
As Jonesy said, lock it up, close bonnet and test using the 12S at the rear.
How about just hooking up a 5W solar trickle charger for $20?
I think I now have the reason I kept having low battery levels in the D2.Makes sense as the issue started after fitting the DBS the battery system.The D2 also had long rests between use,more than the D4 at the moment.D2 averaged 10000km per year whilst I owned it,D4 just turned 8000km in almost 7 months.Quote:

Tested the batteries at 6am today,12.77V.and at 5.45pm 12.77v.Initial drop off probably due to the charger just being disconnected and batteries balancing.

Andy - lock the damn car!
You do realize by law (and insurance) if the car is currently tampered with or stolen your insurance is void (and you can be subject to fines as well for unsecured vehicle)
