Must be cheap ones then. The minimum should be 16mm and decent ones are
25. But cost.

It's really a matter of how long you are prepared wait, for enough
charge to be put into the flat battery, to be able to start the car.
Connect with thick enough cross section cables and good clips and you
would be able start as if the good battery were in the car. Most jump
leads with a completely flat battery need the engine running and a few
minutes, before there is enough to start the car.

Rather than full size jump leads I carry in my boot for emergencies, a
pair of home made leads. I used four of the large clips as used to be
used on old battery chargers and for leads coax cable - not TV coax,
but commercial coax which is double copper screened. Very flexible and
they do contain quite a lot of copper, but not enough to provide an
instant start - five minutes of charge and even my biggest engine will
start.

Hum, so a less than 10AHr SLA can fully charge a 60AHr car battery in
6hrs, interesting... I think dennis has just solved the world energy
crisis.

You are TMH ICMFP as you can plainly see that I said nothing of the kind.

"Such a device could probably supply 10A, which would fully recharge a
typical battery in about 6 hours" - sounds pretty much like teflon Dennis is
at it again...

Explain the difference between your statement at that of Mr Liquorice
halfwit.
