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. 

 
2. 

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

 

 

For charging 12V 5Ah to 100Ah batteries 
Maintenance for 12V 5Ah to 150Ah batteries 
Suitable for charging WET and Gel batteries

 

 12.5A

 

 

For charging 12V 70Ah to 250Ah batteries 
Maintenance for 12V 70Ah to 360Ah batteries 
Suitable for charging WET and Gel batteries

 

 25A

 

 

For charging 12V 150Ah to 550Ah batteries 
Maintenance for 12V 150ah to 800Ah batteries 
Suitable for charging WET and Gel batteries

 

 5A

 

 

For charging 12V 5Ah to 100Ah batteries  
Maintenance for 12V 5Ah to 150Ah batteries 
Suitable for charging AGM-START&STOP and AGM-SPIRAL and EFB or WET batteries 
with temperatures below 5C° 

 12.5A

 

 

For charging 12V 70Ah to 250Ah batteries 
Maintenance for 12V 70Ah to 360Ah batteries 
Suitable for charging AGM-START&STOP and AGM-SPIRAL and EFB or WET batteries 
with temperatures below 5C° 

 25A

 

 

For charging 12V 150Ah to 550Ah batteries 
Maintenance for 12V 150ah to 800Ah batteries 
Suitable for charging AGM-START&STOP and AGM-SPIRAL and EFB or WET batteries 
with temperatures below 5C° 

 5A

 

 

For charging 12V 5Ah to 100Ah batteries 
Maintenance for 12V 5Ah to 150Ah batteries 
Suitable for charging lithium batteries

: LiFePO4

 (do not charge other types of lithium 

batteries) 

 12.5A

 

 

For charging 12V 70Ah to 250Ah batteries 
Maintenance for 12V 70Ah to 360Ah batteries 
Suitable for charging lithium batteries: LiFePO4 (do not charge other types of lithium 
batteries) 

 25A

 

 

For charging 12V 150Ah to 550Ah batteries 
Maintenance for 12V 150ah to 800Ah batteries 
Suitable for charging lithium batteries: LiFePO4 (do not charge other types of lithium 
batteries) 

 

Lithium batteries are equipped with a BMS that in some cases can prevent the start of 
the charging cycle; in this scenario to activate the charge process Press and hold the 
“Function" button for 5 seconds, after setting the charger in lithium mode. 

 

4A-8A-16A 
AGM

 

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, 

recovery must be carried out with battery removed from the vehicle. A battery recovery connected 
to the vehicle could cause damage to the on-board electronics. (Only in 12V mode)

 

 
After selecting the appropriate 12volt function the charging process starts automatically after 5 seconds.
