The charging time depends on the state of charge of the battery. If the battery is completely discharged,
the approximate charging time until the battery is approximately 80
% charged can be calculated using
the following formula:
Battery capacity (Ah) ÷ Charging time (h) = Charging current (A).
The charging current should be
⅒
to
⅙
of the battery capacity.
Note!
Gases are released during the charging process. Make sure that the rooms are well ventilated.
As long as the unit is charging, the LCD display lights up green. When the battery has finished charging,
the LCD display lights up blue.
Stopping the charging of a battery
•
Pull the plug out of the socket.
•
First detach the black charging cable from the body.
•
Then disconnect the red charging cable from the positive terminal of the battery.
•
Important!
In case of positive earth, first disconnect the red charging cable from the body
and then the black charging cable from the battery.
•
Screw or slide the battery plugs (if present) back into place.
Testing 12
V batteries
Connect the charger to the battery. The LCD symbol “H” (fig.
2) indicates the state of charge (1
bar =
25
%). The battery voltage is shown on the LCD display.
Overload switch-off
The charger is equipped with electronic protection against overcharging, short circuit, and reversed
poles. In addition, one or more fine-wire fuses are fitted. If a fuse is defective, it must be replaced by a
new fuse with the same ampere rating. If necessary, contact a qualified electrician.
Battery maintenance and care
•
Make sure that your battery is always securely fastened.
•
A proper connection to the mains supply of the electrical system must be always ensured.
•
Keep the battery clean and dry. Apply a thin layer of grease to the terminals with an acid-free
and acid-resistant grease (e.g., Vaseline).
•
For batteries that are not maintenance-free, check the acid level about every 4
weeks and
top up with distilled water if necessary.
Danger!
Always disconnect the mains plug before starting cleaning work.
