Hi All
i have a slight issue with my 2019 XE R Sport

i hadn't driven it for 12 months and the battery was dead and i mean Nothing - Zip - DEAD FLAT
i manually unlocked the car put some jumpers on the front terminals under the bonnet and opened the boot to gain access to the battery
i fitted a new battery
all good so far.

When i went to start the car i have no dash panel lights or stereo. and the car wont turn over at all.
I've tried locking and unlocking the car manually and electronically. do i need to wait for a set time before restarting the car. (Does something have to recharge in the computer before starting)

am i missing something here

Thanks in advance

 

Current battery voltage is 12.4v I do recall reading somewhere that 12.6 is minimum required to start the xe Jag is this correct, Could this be my issue
