Flat battery

[Baj]

Hereby known as Flattery.

I have a Flattery due to playing with the headlights and listening to my huge stereo while buggering about with LEDs.

Is there anything I need to know before jump starting a 99 ME7 Auto V70?
I have not had a car with so many computers on before and dont want to fry anything expensive :)

I have a 2001 V70 t5 & have boostered it at least a dozen times in the last week with no ill effects. Battery now changed & all OK.
