Hi All.
Well. I thought I did right in getting a car jump starter as a just in case for the RR.
We all know we can have thous occasional 'issues' meaning we need assistance to start.

Anyway. Sunday morning I needed it. The car battery was dead.

So with smugness, i got out the jump starter and no joy..all I got was a click from the starter motor.
It has a starting current of 300A and peak at 450A and a capacity of 450A. It was fully charged. its a Smart Box 21

My question is this. Is there a best way to use one of these with relation to what terminals I use?

I had a car close by so, used my jump leads and all was fine.

Your thoughts?
