That would be until flat but somewhere along
the
line you need a big wad of amps for 10 secs to start.

Typical car battery is probably around 50Ah, and your
typical
laptop battery
is probably 2-3Ah. If we say your laptop runs for 2
hours on its 2.5Ah
battery, then it'll run for 2x(50/2.5) hours which if
my
maths is good today
is 40 hours. Obviously, how long your laptop
runs
for, and the size of the
batteries is variable. Quick
formulae...
time on car battery = h(c/l)
where:
h = time
your
laptop runs for
c = car battery capacity (Ah)
l = laptop battery
capacity
(Ah)
