Defective batteries
• Damagedbatterieswhichdonotretaintheir
charge.
It is often the case that batteries which
are in very bad condition can no longer be
charged; they need to be replaced because
they do not retain their charge.
• Shortcircuitedbatteries.
If, after several hours the battery charger
still does not indicate that the battery is
being charged, this usually means that
one of the elements is short circuited. The
battery needs to be replaced.
Malfunction
If your battery charger no longer functions
as it should, this may be due to the following
reasons:
• Theclamphasbeenconnectedwrongly.
Checkiftherightclampisconnectedtothe
right terminal.
• Thesafetyswitchisswitchedoff.
Battery life
The life of your battery will be considerably
longer if the following advice is taken:
• Checktheliquidlevelofthebatteryevery
month and, if necessary, fill it up with
distilled water.
• Cleantheterminalsofyourbatteryregularly
to prevent deposit. Put a little bit of vaseline
on the terminals.
• Ifthevehicleisseldomused,thebatterywill
discharge. Therefore it needs to be charged
regularly to maximum capacity. In this way
malfunctioning can be prevented.
If everything has been checked, and the battery
charger still does not charge as it should, it
needs to be taken to the Service address on the
warranty card.
