Sitting in the car waiting for my wife tonight, engine off, ignition off, radio on and after about 10 minutes I got a warning on the radio screen that said 'low battery'. I immediately started up and left it running but is that a sign that the battery is on its last legs? It is the original battery so it's getting on a bit. Going to Cornwall on Sunday and wondering whether I should run out tomorrow and get one. Has anyone else had this? Past: FL2 TD4 HSE Auto

Yes many times from when first purchased the car at 18 months old. Either when listening to the radio for extended peroids or powering my MSA frequency PMR radios on car rally's.
But as you say run the engine for 5 minutes and it took a least 5 hours with the radios in listening mode with occasional transmit for it to reappear.

Have to say do not quite understand this as it has happened only an hour after completing a 250 mile run and then as above.

This is an automatic warning that pops up when you have been listening to the radio on battery for about 10 minutes. It has nothing to do with battery level. Most other cars will run the radio for about an hour before shutting down but maybe the LR has a bigger drain so the time is less.

Had this happen to me Steve after running the radio while washing the car... Think it's just a fail safe....
Got the battery checked day after and was told its fine  BETTER looking half of the famous Twinlanders
