Flat battery

L322 Range Rover Vogue 2004 4.4petrol

My battery goes dead after leaving the car for 8+ hours. The battery is 6 months old and has been drop tested and is fine and if I fully charge it off the car its still fully charged a week later if I don’t put it on the car. Drove around for a week or so with a volt meter attached and was always over 14v and have tried pulling different fuses over night but no joy. Its now sat with battery reading 6.7v and my friend phoned me to say there is a glow from one of my headlights. Once I got home I looked and it was just the n/s full beam light glowing and flickering. Ive had the car 9 months and no end of problems with the eas and now it has a can bus problems I did wonder if this was related to the battery problem but 2 days ago I did the coil conversion (yes I know) but haven't told the computer yet just unplugged the power to the air pump. Many Thanks

As ^^^^ best place to ask.

Got any water in the rear cubbies. Battery drain is common so the good guys can help

Good luck

Hi there and welcome
Let it go to sleep then use a dvm to measure milli volts across each fuse

Are they aftermarket headlights? Led bulbs?

Many thanks everyone. I have posted on the other site. No they not aftermarket lights or bulbs just a standerd bulb that i belive is a H7
