Maybe, I just don't know anyone else with a 2010/11 diesel though.

I found that if the battery was pretty low, the engine fan would come on and stay on,, and flatten the battery. Is this what happens in your case?

Cool stuff.

I haven't personally experienced an issue with the fans - they aren't ever on when I get out the car. Do yours start up randomly?

Mine did the random fan thing - but the software update stopped that.

Still getting intermittent (and it isn;t happening ALL the time) 'low battery' warning though.

I think we're forgetting though that the car is actually doing what it's supposed to. The battery simply isn't up to the job. I don't think there's any other car that displays a 'Low Battery' warning though - it'll just go dead.

I agree.

I just don't want it to get to the stage where the battery is flat and it won't start at all. And until my battery is replaced for one that is actually up to the job, there's a danger this might happen. Which is daft on a new £xsquillion car.

Can anyone confirm what the replacement battery is going to be?

I just spoke to me Dealer. But to be fair given there's no 'fix' announced yet, it seems daft me asking them to come and collect the vehicle.

I think I'm going to deal with LR direct and see what joy I get. >happy to rock around in a new Disco, until ours is fixed - or maybe they can get the 'fix'/right battery out to the stealer to fix?

Thoughts?

i love the comment "speak to LR direct"
i have been doing this for the last 6 months with an ongoing electronics fault on my TDV8 with no success.
you're probably better off with the dealer

ah, ok. Good to know. Having not chatted to them previously, I thought it'd be good to get an idea of what they're like.

I think you're being over-cautious. If your car has the latest up to date software, it is highly unlikely the battery will fully discharge. I have left mine without starting (despite having the low-battery warning when I went to get something out the car) for two days and it was absolutely fine. Providing there is no other drain (which is unlikely with the new software), you should be fine. A battery charger is certainly not needed - the vehicle will charge the battery when it needs to. I have had the system explained to me properly now by a technician and my car does behave exactly as it should.

Ok thanks for the reply. Appreciate it.

So, chances are, even if the low battery warning comes on, normal use will keep it charged up, enough to stop it completely discharging?

You have the latest software, and are still getting 'low bat' warnings and using the car normally and it hasn't left you stranded?

If I knew what specs the 'replacement' batteries were going to be, I'd be tempted to source one and fit it.

That's okay. It's a stupid situation to be in but hey!

Yes providing there is no real additional drain on the battery. The warning will also be displayed if there is currently a heavy drain on the battery from what I gather e.g. you have the ignition switched on, RSE, radio etc. It's basically saying it won't be able to cope with that amount of drain for long. The BCM will also switch off items that it doesn't require to maintain battery e.g. DVD changer, CD changer as these are 'non-essential.' This is actually in the handbook under 'Battery.'

Since having the latest software applied (very recently), I have had the warning once or twice. I am even tempted to say that I may have the new battery installed but my dealer is somewhat unsure as to whether my vehicle actually has it - my car was early March build and the new batteries were apparently already included then. Where even is the battery in the Range Rover? The new spec battery should be an AGM style battery. I would avoid sourcing a battery yourself...the last thing you want is them to say you've voided your warranty using a non-approved agent etc.

Not sure if you know, but in order to get the 4.4 so efficient, the alternator will only be on when the battery NEEDS charging. As soon as you switch on the engine after getting a low battery warning, the alternator starts charging again. The battery is therefore only charged the bare minimum from what I was told.

mine does exactly as it should until i try to do something which takes battery power when the engine is turned off - like listen to the radio..or use the FBH. 30 minute shut down of the radio or 10 minute shut down of the FBH to preserve the battery is not good on a car costing 80k plus.
in fact it is unacceptable.
I suspect that a fair few people who tried LR due to the exceptionally poor last couple of winters may be quick to desert the brand after a couple of mild winters.
and LR will have only itself to blame.

This is great info, thanks for all that.

I'll keep an eye on it

Our car was ready early March, so probably has the 'old' battery.

I have friends (3!) with the same MY11 FFRR and they've all had flat (fully discharged) batteries. But they had their cars towards the end of last year (oct IIRC) and I suspect that since (with software updates etc) they've had no flat batteries.

I must check and see if they've had the low bat warning since.

No probs

I haven't been brave enough to try the FBH though...have you??

Nah, wife was the only one of us who had the 'fbh' remote on her keyring and she lost the battery cover bit, so i've hidden it anyway

Given we're too scared to use it we ought to ask for FBH's worth of compensation?

Haha yes true - I think so.

Re: battery, I think it's just plain stupid that the batteries are all the same across the range and do not take into account the equipment level chosen - someone with 100% standard spec has the same battery as someone with a full spec car.

Re FBH: To be fair though, it does work! I got very freaked out when all this smoke started coming out from under the driver's door but it was cold outside and I had just started the engine. The FBH comes on to assist the engine in heating up. I've only seen it work once as it's been very mild. I read somewhere though the smoke dies down after a few uses.
