WARNING: Always make sure that all connections are secure and stable. Always make sure that the
device is laying stable and cannot slip and fall down.
Protection against polarity reversal: If the clamps or eyelets have not been correctly connected to the
battery, this is signalled on the device with a flashing red LED. The plug should then be removed from
the power socket and the connection process should be reversed.
Always make sure that there are no electric consumers connected to the battery when the item is
maintenance charging. Shut off ignition of the car, lights etc..
Don’t open a battery terminal in modern cars. In modern cars the current to hold the memory in the
different electronic units is less than critical for our maintenance charger.
Please check from time to time that the power socket has still voltage and no one pull out the power
plug from the socket.
CHARGING PROCESS FOR THE DEVICE
The device can be connected to a standard 6V or 12V car battery / starter battery / motorbike or
scooter battery. It starts the fully-automated maintenance battery charging process, including se-
lecting the charging voltage required depending on the type of battery being used (6V/12V) in a fully-
automated process.

No voltage supply. Check wall power socket
Red LED is flashing:
Device is not charging. Check clamps and contacts. Clean any dirty contact.
Or:
If polarity is reversed (+ with –), the clamps should be connected correctly.
Then first disconnect the plug from the power supply and start the connecti-
on process from the start as previously described.
Red LED is on:
Device is maintenance charging the vehicle battery
Green LED is flashing: Battery is over 80% charged and usable for engine start.
Green LED is on:
Battery is fully charged and usable for engine start. The maintenance battery
charger stops charging and waits until voltage fall down to 6,5V/13V (6/12V
battery). Then automatically starts maintenance charging again. This is run-
ning in the background and not visible.
