could be left unattended and never overcharge your batteries. 

 

 

BS’s  Pro  Smart  Chargers 

are  suitable  for  most  12V  automotive,  marine  and  deep  cycle 

batteries: They could help to restore drained or sulphated batteries. 

 

Short  circuit  protection: 

The  charger  will  automatically  turn  off  when  the  output  short 

circuit occurred and prevents any damage

The  charger  can  automatically  shut  off  when  the  output 

polarity reversed and without damage

 

 

Never overcharge your battery  

 

Heavy-Duty cables 

 

Corrosion-resistant output connectors  

 

Output clips and ring terminals provided: 

It comes with a quick connect fly lead and 2 

different kinds of connectors, crocodile clips and a ring terminals. The ring terminals are 
perfect for permanent connection to your battery. You can connect the lead to the battery and 
tuck the lead away while you are using your vehicle and when you get back to your garage 
simply plug the lead back into the charger

The 7 Stages Charge are: 

o

 

Rejuvenation

: Rejuvenates sulphated batteries with a high frequency pulse 

o

 

Soft Start

: Increases battery life by gently starting to charge the battery. 

o

 

Bulk Charge

: Reduces charging time by delivering maximum charge to set voltage. 

o

 

Absorption

: Ensures a full charge to the battery without overcharging. 

o

 

Equalisation (Calcium Mode Only)

: Returns a full hydrometer reading to calcium 

batteries by removing acid stratification. 

o

 

Battery Test

: Tests the battery to ensure fully charged. 

o

 

Float

: Float charge maintains the battery at 100% charge.
