Aggieturbo Posted January 3, 2009 Share Posted January 3, 2009 My LR draws about 140 milliamps when everything is switched off. Presumably this is the clock as there is nothing else I can think of. I don't have anything non-standard (that I am aware of!). Does this value sound ok or is it too high? Thanks, Tony Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 3, 2009 Share Posted January 3, 2009 Sounds reasonable - unless you've got good reason to think otherwise? Quote Link to comment Share on other sites More sharing options...
Aggieturbo Posted January 3, 2009 Author Share Posted January 3, 2009 The vehicle doesn't get used much, maybe only once in two weeks, and it turned over very slowly this morning. In the end I had to put it on charge for a couple of hours to get it to start. It had a new Bosch battery in Feb 2007 so would have thought that was okay. I guess it's just lack of use and the cold weather. Does anybody know how far you need to travel to replace the power used to start it? the other problem is that when I do use it I may only go a total of 10 miles including a stop. I have an isolator switch by the battery compartment, I think I'll try using that to se if it preserves that battery. Quote Link to comment Share on other sites More sharing options...
western Posted January 3, 2009 Share Posted January 3, 2009 probably drawn by the clock & radio memory [if fitted] sounds reasonable. putting it on charge overnight is much better. Quote Link to comment Share on other sites More sharing options...
landy andy. Posted January 3, 2009 Share Posted January 3, 2009 Driving it for 10 miles in this weather, with heater on, lights on, rear demister, and heater, I doubt your putting much if any charge back in to the battery, after having used the glow plugs and then a few spins on the key. Just a thought??? Andy Quote Link to comment Share on other sites More sharing options...
Aggieturbo Posted January 3, 2009 Author Share Posted January 3, 2009 Heater? Rear Demister? what are they, its an 88 Land Rover for goodness sake! - Your probably right though, I do try to be conservative with the eletcrics. Quote Link to comment Share on other sites More sharing options...
western Posted January 3, 2009 Share Posted January 3, 2009 if your heater isn't giving it's best have a go at adjusting the cables/flaps Quote Link to comment Share on other sites More sharing options...
santalars Posted January 6, 2009 Share Posted January 6, 2009 140 mA sounds ok. Depending on the size of your battery that will give you 100 to 400 hrs before you get trouble with starting. As I have some additional systems which permanently draw some power and my car is sometimes parked for up to two weeks I have fitted a solar panel and a charge controller to keep the battery topped up at all times. I have a 20 Wp panel and all together it was around €150 (the same in pound at current). I have the same system on my boat and I'm very satisfied with them.

Cat_J Posted January 6, 2009 Share Posted January 6, 2009 If you had a 95Ah battery it would run at 140mA for 678 hours. A 65 would last 464, a 45 would last 321. 168 hours in one week 336 in two so with a 95 Ah battery you should still be able to start after and week and in good weather after two. Obviously a lesser battery would suffer more but I've left some quite draining things on before and still started on my 95Ah Bosch. What is your batterys CCA?

crazyfarmerboy Posted January 6, 2009 Share Posted January 6, 2009 if you are going to be leaving it alot for 2 weeks just disconnect the battery before you leave it. Does not take long but you will have to cahnge the time on the clock. That is what i do when i know i am leaving mine. thanks Quote Link to comment Share on other sites More sharing options...
western Posted January 6, 2009 Share Posted January 6, 2009 or fit a isolator for a easier disconnect without going into the battery bay. Quote Link to comment Share on other sites More sharing options...

I've allowed for some potential to remain in the battery to operate the glow plugs and the starter motor. No point in having the battery empty. Here's a picture of my solar panel: Quote Link to comment Share on other sites More sharing options...
Three Blades Posted January 7, 2009 Share Posted January 7, 2009 Buy one of these for £10 at Maplin (they are on discount) and leave it on the dash to top up the battery when you leave it for days on end. http://www.maplin.co.uk/Module.aspx?ModuleNo=47902 Quote Link to comment Share on other sites More sharing options...
