Low battery warning

Here’s a strange one.
Ctek’s plugged in showing all lights so indicating alls well.
Obd reader shows 13.9 v before starting and battery’s good.
Why then is the dash telling me low battery. Start car ?
Any ideas

Hi Alastair,

Yes there is two batteries, one aux batt on rear r/h side cubby hole.
Main battery in boot
May have to dig the aux batt out

Could be that ODB is reading one & the alert is reading the other ?

Other than that - agree that it seems odd..... though I remember mine doing it if I ran things for too long without starting it - and then it would start first time, so may be nothing to worry about if you've been sitting there running accessories for a while....

Do you double-lock the car when you leave it, otherwise it still has stuff running. 2017 SDV8 4.4 silicon silver AB

Hi Tinman,

Always double lock where ever i am, enhances security which was also highlighted in the security letter drop from LR a couple of weeks ago.
Cheers
