Is it ok to disconnect the battery for a month if I'm a traveling ?
I have a Jaguar XJ8 and I would like to know what setting would be different when I return like if I am going to loose any saved data from the air suspension system or from the main computer or new fault messages .
I just do not see the point of leaving the battery connected if I am not going to drive the car

 

If you you leave the battery connected you will have the benefit that the car is locked with

alarm and immobiliser activated.

 

Get a small 1-2 amp battery tender, they're inexpensive and keep everything fully charged and all your settings remain.

Thanks

Thanks good idea
