CTEK ZAFIR 100 - Manual (Page 3)

MODE
”NORMAL” (14.4V)
Normal setting for wet batteries, MF and for most Gel batteries.
Mode ”SNOWFLAKE” (14.7V)
This setting is recommended for batteries at temperatures below 5°C. It is also recommended
for many AGM batteries. This setting is not recommended for maintenance charging when the
temperature at times exceeds +5°C. In this case, the NORMAL mode is recommended.
Mode ”SUPPLY” (13.6V)
The ZAFIR 100 can be used as a power supply without a battery attached in this setting. No
counter voltage is required to start the charger in this mode. Note that the charger is not spark
free in this mode.
Mode ”RECOND” (15.7V, 1.5A 0.5–4h)
This mode is used to recondition very discharged batteries where you could expect a stratified
acid (high acid weight in the bottom, low on top). Use this mode with care because it can cause
some water loss.
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 cable 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 cable 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 cable 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 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 connector can be connected.
Reverse Polarity Protection
If the battery cables are connected incorrectly, the reverse polarity protection will make sure
that neither the charger nor the battery are damaged. In this case, the red warning lamp (0) will
be lit.
Start charging
1. Connect the power cord to the power outlet.
2. Set the proper charging mode for the battery by pushing the Mode button until the correct
setting is lit. Choosing settings for your battery is described under ”BATTERY TYPES AND
SETTINGS”.
