On a severely discharged battery,
use the 40A Boost mode for
few minutes, to help assist in
cranking.
Crank time varies with the amount
of current drawn. If cranking draws
more than the engine start rate,
crank time may be less than 5
seconds.
The thermal protector may have
tripped and needs a little longer
to reset. Make sure the charger
vents are not blocked. Wait and
try again.
