If you don’t change the default Ah value (indicated by an ?)
the charger will use the default Ah rating that comes closest
to the entered CCA value.
There can be a dierence between the entered CCA value
and the default Ah value since there is no direct one to one
relation between the two. The default Ah value will come
close but there can be dierences found in the eld. The
advise is to always enter the true Ah value of the battery.
