CHARGING A LEAD-ACID BATTERY
• First ensure that it is a lead-acid battery with a voltage of 6 V or 12 V. Rechargeable batteries with other voltages cannot be charged!
• Disconnect all consumers from the rechargeable battery.
• If the rechargeable battery is built into a vehicle, switch off the ignition and all consumers.
Please strictly observe any and all information and safety instructions of the vehicle on how the rechargeable vehicle battery needs to be
charged. Modern vehicles are equipped with sensitive electronic components and control units which will be damaged when handled
improperly!
• First, connect the charger to a mains socket (220 – 240 VAC/50/60 Hz).
• Now, connect the charger to the rechargeable battery observing correct polarity. Reverse polarity on the connected rechargeable battery is indicated by LED 3.
• Then, you may select one of the two modes by activating the MODE button. The next chapter contains the description of the individual operating modes.
¼
Only in the first 10 seconds after connecting the rechargeable battery, it is possible to select the desired charge mode. If you, for example, selected the
wrong mode, you must disconnect the rechargeable battery once again from the charger and reconnect it.
• After charging, disconnect the charger from the mains voltage.
• Then remove the terminal from the minus pole of the rechargeable battery and then from the plus pole.
DESCRIPTION OF OPERATING MODES
6V mode (1)
The 6 V-mode is suitable for charging rechargeable 6 V batteries with a capacity from 1.2 Ah (please observe the technical data of the battery manufacturer
concerning the maximum charging current).
Press the MODE button again and again until LED 1 flashes. After approx.
10 seconds
the LED is constantly on and the charging procedure starts.
The charging current is 1 A +/- 10%. At approx. 7.1 V the charging current will be reduced to 0.6 A. The charging end voltage is 7.2 V +/- 0.2 V.
LED 4 indicates the charge status. When the LED is constantly on, the rechargeable battery is full.
12V mode (2)
The 12V mode is suitable for charging rechargeable 12 V batteries with a capacity from 1.2 Ah (please observe the technical data of the battery manufacturer
concerning the maximum charging current).
Press the MODE button again and again until LED 2 flashes. After approx. 10 seconds the LED is constantly on and the charging procedure starts.
The charging current is 1 A +/- 10%. At approx. 14.2 V the charging current will be reduced to 0.6 A. The charging end voltage is 14.4 V +/- 0.2.
LED 4 indicates the charge status. When the LED is constantly on, the rechargeable battery is full.
Regeneration mode
If a deep discharged rechargeable battery is connected to the charger, the regeneration mode is the first mode to start. Pulsing charging currents are used to try
and bring the deep discharged rechargeable battery to a voltage at which regular recharging function can be started. The maximum time of the regeneration mode
is 20 minutes. If no adequate battery voltage can be achieved during this time, the charger stops the process, the battery will be detected as defective and LED 3
is on.
Defective rechargeable batteries/Short-circuit and reversed polarity protection
The charger recognises defective rechargeable batteries automatically. In this case the selected charging programme will not be started. LED 3 is on.
Rechargeable batteries with short-circuit respectively with reverse polarity connection will also be detected immediately. In consequence the charging programme
will not be started. LED 3 flashes.
