4 Operation
Operation of the booster is not required for daily use.
Only when the battery type is changed (for possible battery types, refer to
Section 5.1), during initial start-up or when retrofitting accessories do one-
time settings have to be configured (see Section 8).

This means the maximum charge current (
to
70 A
) is possible when the alternator is delive-
ring full voltage (14.6V) and the leisure area
battery is discharged (refer to last column).
Measurement: Vehicle with LiMa voltage 12.6V
to 15.0V; voltage drop on the cable to the star-
ter battery: 0.4V; Leisure area battery: 14,7 V
(almost fully charged) or 12.5V (almost flat)
Maximum input current
60 to 65 A
