Just acquired 2011 Discovery 4 and getting Low battery warning after few minutes listening to ipod without engine running. I guess ive got a duff battery but will check levels etc.

Can someone recommend good heavy duty battery make?

I went through a few batteries on my voyager which needs a heavy duty battery as everything is electric - seats, doors, boot lid etc + an agricultural 2. 8 diesel to turn over. The best i've found & its been on the car 3 & a half years now & never let me down is one from halfords - in fact its a halfords own brand. I've replaced like for like from chrysler, like for like from our local factors & even ordered from a battery 'specialist' only for them all to fail after a year to 18 months.

Had no choice when buying this one as it was boxing day morning & halfords was the only place open. cost a couple of quid more, but only maybe a tenner more & as said its been on there 3 & half years now & is perfect no matter how many times my 3 year old opens & closes the doors when he's got hold of my keys.

 

PS - Don't mention your D4 having a problem to C1 or Griff. ................ :P:P

2011 model its now 2014 the battery is had it get a new one. If you want the best then buy an Odyssey, not cheap just the best!! It might be worth while getting the D3 checked over on diagnostic at a good independant LR specialist as you could have something like a door lock switch that is not working and one or more of the ECUs are not being turned off when the car is locked over night resulting in the battery running down.

It's not uncommon to get that warning. The thing is that whilst the radio/mp3 etc is playing, many of the car's other systems are still "awake", and the D4 system is very sensitive (perhaps a little too sensitive?), so gives the warning. Still, it's better to be warned than not having the power to start the car.

 

By all means get the battery checked, but you'll probably find that it's fine. It's a regular question on the disco4. com forum.

Sorry you have a D4 not a D3, but they are almost the same thing and have much the same problems. Get the battery checked and the D4's systems.

They look pretty similar, but they are quite different vehicles. See my post above re the battery warning. ;)

The battery monitoring system (BMS) will shut the car down in order to preserve enough charge to start the car - this is normal and has done this on my 61 plate D4 since new, after only about 5 or 10 minutes listening to the radio without the engine running.

Also, the alternator will be reluctant to charge the battery until the car is on over-run, in order to reduce fuel consumprion, so it takes a lot of driving to restore the battery - check this out in the disco4 forum.

 

Get the battery checked as others have said, but I don't believe you have a problem.

Thanks, I think you may have identified the issue.

I had not been doing long trips for 10 days only doing short trips to shops etc . ...after being laid up with a virus.

After posting this thread I did a 50mile trip and waiting for the wife in a shop I played the IPod with no message. I guess I haven't been doing enough charging miles this week.

 

Should have known. ...my father had same problem earlier this year.

The car is hungry for battery - in fact some D3 (and D4) owners fit a second battery.

You will find the battery will misbehave even more later in the year when there is more drain from lights and screen heaters etc.

For me this manifested itself in the park heating not operating from time to time - the BMS likes to ensure you have enough charge to start the engine, and I have never had a failure in this respect, even on the coldest of days.

There are two solutions:

Drive the car a lot, 50+ miles at a time.

Or, charge the battery up once a week during the winter. You can buy an adaptor for a CTEK charger from the Disco4 forum (or make your own) that plugs into the tow socket (12S or 13pin) that makes life easier, but obviously you would need to be parked close to a power point, and the tow socket flap needs to be removed.

My battery and probably yours, is AGM, and they are better at withstanding long periods of low state of charge than normal lead acid batteries. AGM batteries need to charge on the snowflake symbol on a CTEK.

 

Edit: Definitely worth registering on the forum - they even have a caravanning section, but not as good as CT :rolleyes:

To be fair a lot of newer cars are like this, the last couple of Ford Mondeo's I have had have done the same, and they are driven regularly and have not had any problems with battery. But park up and sit with radio on and after 10-15 mins it will warn of battery voltage. If you ignore it, it will eventually turn the radio off. Seems to be designed to protect battery from draining, so fair enough.

I have joined the disco3. com, thanks for the heads up. But, since you raised it here, why bother getting the caravan plug adapter for the Ctek? Cannot the loadspace 12v PowerPoint (which isn't ignition dependant) be used to charge the battery using the Ctek 'cigarlighter' adapter?

I think you'll find the D4's load-space power point is switched.

One make, forget which but not LR also has this clever idea of only charging when it feels like and the fix being to drive with the side lights or something on all the time for the ECU to "see" a small load. Just a thought

Mine is definitely ignition dependent - perhaps yours has been modified Eric.

Yes, so is mine. Just checked it. They will power for a few minutes, perhaps giving the impression that they're not switched.

Sneaky!!

 

I just stuck my RAC Ring inflator in for a few seconds . ..and it whirred. ...so I 'assumed' (fatal error I know!) it was unswitched.

 

Confess I can't be bothered to go back out and recheck. LOL. ......have ordered the caravan plug version from Disco3.

 

Thanks Gents
