Safety

Read Icon
Before use your charger, please read all instructions carefully.

CAUTION

If the supply cord is damaged, it must be replaced by the manufacturer or its service agent in order to avoid a hazard.
Disconnect the supply before making or breaking the connections to the battery.
The battery connection, which is not connected to the vehicle body, must be connected first (+) red. The other connection must be made to the vehicle body (–) black, away from battery and fuel lines. Only then connect the battery charger to the mains supply.
After charging, disconnect the battery charger from supply mains. Then remove the chassis connection and the battery connection, in this order, the conductor to be connected to the positive pole shall be colored red and that to be connected to the negative pole shall be colored black.

WARNING

The AC power plug must not expose to the water, and have to avoid the water flows towards the supply mains to protect the users from electric shock.

WARNING

Explosion hazard and fire hazard!
Explosive gases.

Prevent flames or sparks.
Provide adequate ventilation during charging.

Environment friendly disposal

You can help protect the environment! Please remember to respect the local regulations, power tools that are no longer usable must be collected separately and disposed of in an environmentally correct manner. The packaging is made of ecological materials which can be disposed of at local recycling facilities.

Operation

Before commissioning
Read the battery operating instructions before connecting up the charger.
Observe the vehicle manufacturer‘s recommendation if the battery is still connected to the vehicle.
Clean the battery terminals. When doing so, do not allow the dirt to come into contact with your eyes or mouth.
Ensure adequate ventilation. Hydrogen gas (electrolytic gas) may escape from the battery during charging and trickle charging.

Connecting

Connect the (+) port (red) of the charger to the (+) port on the battery.
Connect the (–) port (black) of the charger to the (–) port of the battery.
The (–) connector (black) can also be connected to the body, but far away from fuel lines
Note: Make sure that the (+) and (–) ports are fixed. Make sure that the screws of the clamps are firm.
Connect the power plug to the mains.

Disconnecting

Put the charger into standby mode by pressing the mode selector button.
Always start by unplugging the power cord.
Disconnect the (–) port (black) of the charger from the (–) connector of the battery.
Disconnect the (+) port (red) of the charger from the (+) port on the battery.

Overheating protection

If the unit becomes excessively hot during charging, the output power and output current is automatically reduced to avoid damaging the unit.

Note:

For regeneration mode, make sure that all connections between the battery and the electrical system are disconnected.

Pulse charging

This is an automatic charging function that cannot be selected manually. If the battery voltage in mode 1 & 4 is between 7.5 V (± 0.5 V) and 10.5 V (± 0.5 V), the charger automatically switches to pulse.

Trickle loading phase

The charger has an automatic trickle charging phase with max. 300 mA at full charge

Maintenance phase

When the battery is fully charged, 100 % LED will light up, the charger enters maintenance phase to keep the battery capacity in full condition.

Memory function

If the charger is unplugged during charging, the device saves the previously selected mode. When reconnected to the mains and if the battery is of the same type (6 V or 12 V), the device automatically starts in the last mode.

Attention: If the type of connected battery is different from the last one used (e.g. if the last time was in cold/AGM mode and you need to connect a normal lead-acid battery this time), please reselect the mode manually to avoid overcharging and damage.
For mode 5 (regeneration mode) and mode 7, 8 (push mode) there is no memory function.

Battery detection

As soon as the charger is connected to a 7.3 V – 10.5 V battery, 6 V & 12 V LED will flash alternatively, the charger will try to automatically detect the battery voltage (6 V or 12 V) in a complex measuring procedure. After 1-3 minutes, the charger will detect whether the battery is a 6 V or 12 V battery and switch to the appropriate 6 V mode or 12 V motorcycle mode.

Override Mode

If the charger detects that the connected battery is a 6 V battery and enters 6 V mode, but the user is very sure that it is a 12 V battery, the user can press and hold the mode button for 5 seconds to switch the charger to any 12 V charging mode.

CAUTION

Please only use this override mode if you are sure that the battery to be charged is a 12 V battery. The 12 V mode can charge the battery already from 3.75 V low voltage. Therefore, a 6 V battery could be overcharged and further dangers (increased gas leakage, explosion, fire…) for humans and animals.

Device protection function

In the event of a short circuit on the charging cable, the fuse (5b) on the charging cable prevents damage to the device and the electrical system

Maintenance and care

Always unplug the mains connector before cleaning the charger.
The device is maintenance-free.

Turn off the device.
Use a dry cloth to clean the plastic surfaces of the device.
Never use solvents or other aggressive cleaning agents.
The devices may only be repaired by qualified personnel with original spare parts in order to maintain operational safety.
For 24 V battery, please use C70.
