start.
If one of the options above occur, the charger shows this by turning to 'Power Safe Mode'
and the power lamp starts flashing green.
Can I start my vehicle whilst the charger is connected?
Yes. Remember to disconnect the charger from the vehicle before moving away.
Can I leave the charger connected to the battery for a
long time?
Yes. CTEK chargers are designed to fully charge a battery and then automatically switch over
to long term maintenance. Before leaving the charger unattended for a long time ensure
that the battery is fully charged as indicated by the green LED.
Can I charge my vehicle through the 12V (cig) socket?
Yes, if your socket is still live when the ignition is turned off. Check the vehicle user manual contact
your vehicle retailer or test it with any other cig-plug device that works with your vehicle. The
maximum amperage charger that can be used is 10A.
Can I use a smaller or bigger charger than recommended
for my battery?
Choose charger depending on the size of your battery. Charging with a smaller charger than
recommended will take longer time and will not optimally extend the battery life and
performance. If your battery has an Ah rating that exceeds that of the charger limit it could
mean that the charger will be unable to charge the battery sufficiently and may even lead to
it becoming discharged. Charging with a bigger charger than recommended could possibly
have an adverse effect on the battery performance and battery service life.
The CTEK manual says:" Connect the black clamp to the
vehicle chassis remote from the fuel pipe and the
battery". In the picture next to this the black clamp is
connected to the battery's negative pole. Which is
correct? "
The charger should be connected according to the vehicle user manual. If there are no other
recommendations in the manual the negative or black connector should be safely connected to the
chassis. If your vehicle has the start stop technology, it will be fitted with a BMS (battery
management system) you cannot connect directly to the negative battery pole the connection must
be made to the earth or ground point. If the battery is disconnected or removed from the vehicle,
then both connections can be made directly to the battery terminal.
