Apologies if this has been asked before but what spec of jump leads do you carry/use in your mini for jump starting?
Back in the old days when you needed Jump Leads you'd just buy a set of jump leads, nowadays (at Halfords at least) there's leads for up to 1.2L, 1.8L, 3.5L etc etc all with different cable ratings.
Car is a 998cc so I'm assuming the up to 1.2L with 10mm2 cable area seems to be the correct choice, but what are the pro's/con's of buying larger cable area size in regards of jump starting performance and/or electrical safety?
