➡
Check the capacity of the charger equipment!
Rule of thumb: At least 1/10th of the battery capacity is
needed, plus consuming equipments in use during the
charging process (cf. p. 8, “The correct charging techni-
que”).
Our recommendation:
The faultless technical condition of
your vehicle is the best pre-condition for safe, problem-
free use. Have your vehicle maintained regularly by a
professional engineer. A thorough vehicle check before
starting your holiday will largely safeguard you against
unpleasant surprises.
