This BOOSTER has been designed to offer you the quality and benefits of a portable energy source. To find 
out about the characteristics of your BOOSTER in detail read these instructions carefully and keep them in a 
safe place for future reference.  
 

Important safety warnings.  
1. 

The use of accessories not recommended or not sold by the BOOSTER manufacturer could cause 
damage to the appliance or to people.  

2. 

When using the LESA power supply unit or the lighter plug cable, always pull on the plug and not the 
cable to unplug the device.  

3. 

Do not recharge the BOOSTER if the plug of the charger or lighter plug cable are damaged but replace 
them immediately.  

4. 

The BOOSTER may be used whatever the weather conditions: rain, snow, high or low temperatures.  

5. 

Do not immerse the BOOSTER in water.  

6. 

Do not use the BOOSTER close to inflammable liquids not protected by suitable containers.  

7. 

If the BOOSTER suffers a sharp blow or is damaged in any other way have it checked by a qualified 
technician.  

 

The BOOSTER should not be left completely flat for long periods of time

. The damage to the 

accumulator could be irreversible thus considerably reducing performance. 

When the device is not used 

for long periods of time it should be recharged at least once every four (4) months

 using the LESA 

power supply unit or the lighter cable.   
 

Technical characteristics.  
1. 

The BOOSTER accumulator supplies 3200A at breakaway (American regulations) in  the first few 
seconds of initial starting, then issues a minimum of 900A in continuous, more than enough to start  most 
petrol and diesel fuelled cars, it’s protected against tension peaks to safeguard electronic control units. 

2. 

1000A clamps with six-wire copper cable.  

3. 

Multifunction electric power supply. Use by means of the lighter plug 24V.  Protection provided by 20A 
automatic thermic switch 

4. 

Light-up indicator charge control button. For full control keep the “TEST” button pressed for at least 10 
seconds. 

Active safety features.  
1. 

The negative and positive clamps are fixed into special slots fitted with copper braid and rubber coverings 
which ensure the maximum safety.  

2. 

The guide slots block the cables preventing unnecessary slack and fouling.  

3. 

The BOOSTER, with its sealed energy battery (12 V/26 Ah x 2), is protected against electrolytic leakage. 
It can be laid down and/or used in any position.  

 

Recharging procedure.  
1. 

By pushing the “TEST” button, the display shows the charge voltage (with mains recharging cable 220V 
inserted in lighter socket). We recommend recharging the apparatus after each time it is used with the 
special automatic power supply unit which allows the accumulator to be fully recharged without the risk of 
overload.  

 

Three ways of recharging the BOOSTER.  
1. 

After the engine has been started leave the BOOSTER connected for a further 3-5 minutes.  

2. 

Recharge using the cable with the lighter plug LESA1 (optional) inserted in the lighter socket 24V. while 
the engine is running.  

3. 

Recharge using the automatic power supply unit LESA 7 24V. Insert the plug of the charger in the wall 
socket and the plug in the booster. The display shows (Lo) if the booster is flat, charge it for at least 30 
hours. 

Most recharging will be completed in 12 hours.
