HOW TO USE THE BATTERY CHARGER

1.
Once the output clamps have been connected to the battery, connect the power cord to the
mains socket, making sure that the voltage corresponds to the rated voltage of the charger.
With the charger in "stand-by" mode, set the appropriate charge parameters using the mode

button to select the correct voltage.
For 12V batteries the following charging parameters can be selected via the "Function" button:
5A
12.5A
25A

The RECONDITION mode is for WET and AGM batteries that have long been inactive and have an
acid stratification. Caution: due to the high voltage that is reached during this charging cycle,
4A-8A-16A
recovery must be carried out with battery removed from the vehicle. A battery recovery connected
