GEL:  14.1V

AGM/WET:  14.4V

Calcium:  14.7V

.  If  the  Battery  Condition  is  still  less  than  12.5V 

after absorption mode, this will be indicated by the GREEN Full Charge LED flashing.

Indicated 

by the BLUE Charging LED ON

 

Equalizing

: This stage begins  automatically if  the Calcium Battery type has been selected. This 

cycle  pushes  the  charge  voltage  up  to  an  equalizing  level  of  16.2V.

Indicated  by  the  BLUE 

Charging LED ON

 

Analysis

:  This stage diagnoses the battery condition within ten minutes. If the Full Charge LED is 

flashing, this indicates that the battery is still less than 12.5V after the absorption mode and that there 
is a fault with the battery. 

Indicated by the GREEN Full LED ON

 

Full / Float

: Battery is fully charged and is ready for use. It will be maintained at a safe constant 

voltage. Battery type selection: 

GEL: 13.4V

 

AGM/WET: 13.5V

 

Calcium: 13.6V

REJUVENATION PROCESS (EXTEND YOUR BATTERY LIFE) 

 

Your Battery Charger provides battery rejuvenation function.  

 

What does this feature do? 

Rejuvenation

 has been proven to break down the crystalline 

form of lead sulphate within the battery cells which helps extend your battery life.  

 

We recommend that you periodically use this rejuvenation (De-Sulphate) feature to ensure 
you get the maximum life out of your battery. 

 

To activate this rejuvenation feature, simply press and hold the ‘Battery Type’ Button for 3 
Seconds until the Rejuvenation LED begins flashing (YELLOW). 

 

Once the charger has entered the rejuvenation (de-sulphate) charging stage, the process will 
automatically time out after 24 hours or you can manually stop this process at any time by 
pressing and holding down the ‘Battery Type’ Button for 3 seconds. 

 

AUTOMATIC EQUALISATION PROCESS (For Calcium Batteries Only) 

Your Battery Charger also provides a battery equalisation function.  

 

What does this feature do? 

Equalisation

 helps to maintain and balance your battery cells by 

reversing the high concentration of electrolytes from the bottom of your battery. 

 

This allows all the cells to charge evenly and makes you get the most out of your battery. 

 

You can activate this feature weekly to ensure your battery is always well maintained. 

Note: If you select the Calcium battery type, the charger will automatically run the equalisation stage during the charging cycle. 
The Equalisation process does not occur for GEL or Sealed/WET Battery Type Selection

 

Depending on the charge rate selected, this process will time out after 1 to 3 hours. 

 

Equalising voltage is set to 16.2V for Calcium batteries.
