Battery defective, too
small or too old. Please
check the battery and
contact EFOY-Hotline
[e-mail]
The on-board electrical system
including the battery has to be
checked. The EFOY COMFORT
has measured charging cycles
which were too short. This is an
indication of a defective, too old
or too small battery. The battery
parameters may also need to be
reviewed. Please refer to chap-
ter 6„Specifications“on page
104, for information about the
recommended battery capaci-
ties. Please contact your local
dealer to check the electrical
system and in particular the per-
formance of the battery. Charg-
ing cycles which are too short
can damage the EFOY COMFORT
fuel cell.
