CTEK XC 800 - Manual (Page 3)

BATTERY TYPES
The following recommendations should only be considered as guidelines. In the event of
uncertainty always refer to the battery manufacturer’s recommendations.
CTEK XC 800 is suitable for charging all types of 6V lead-acid batteries: open batteries, MF,
AGM and most GEL-batteries. Battery sizes from 1.2 to 32Ah. The charger can maintain
batteries up to 100Ah.
CHARGING
Charging batteries mounted in a vehicle:
1. The power cord should be disconnected before connecting or disconnecting the battery
leads.
2. Identify the pole that is grounded (attached to the chassis). Ground is normally connected to
the negative terminal.
3. Charging a negatively grounded battery. Connect the red wire to the positive pole of the
battery and the black cable to the vehicle’s chassis. Be careful not to connect the black cable in
the vicinity of a fuel pipe or the battery.
4. Charging a positively grounded battery. Connect the black wire to the negative pole of the
battery and the red cable to the vehicle's chassis. Be careful not to connect the red cable in the
vicinity of a fuel pipe or the battery.
Charging of a battery not connected to a vehicle:
1. The power cord should be disconnected before connecting or disconnecting the battery
leads.
2. Connect the red wire to the positive pole of the battery and the black cable to the negative
pole.
Connecting the provided cables with eyelet terminals:
Make sure that the cable is not being pinched or in contact with warm surfaces or sharp edges.
When the cable is mounted on the battery, it should not be connected to the charger. Connect
the eyelet terminals to the battery's poles – the red cable to the positive pole and the black
cable to the negative pole. After this, the quick contact can be connected.
Reverse Polarity Protection
If the battery cables are connected incorrectly, the reverse polarity protection will make sure that
the charger and the battery are not damaged. In this case, the red warning lamp
will be lit.
