4 STEP CHARGE

Progressive battery charging curves

Auto adjust

 

STEP 1 - High charge:

 

During this stage the

 

charger supplies a

 

maximum current and

 

the voltage increases

 

progressively according

 

to the battery type

 

selected. This step

 

depends on the initial

 

state of the batteries.

 

The “Fast Charge” LED

 

is on.

 

STEP 2 - ABSORPTION: This is an adjustable

period during which the voltage is kept at its maximum and the current decreases in order to optimise the battery charge. The “Absorption” LED is on.

STEP 3 - FLOAT:

The voltage is kept at float level in order to maintain the charge without increasing the temperature of the batteries. They can be left connected without any damage. The “Float” LED is on.

POWERPACK function: Full current is available for on-board supply.

STEP 4 - RESET:

If the battery voltage goes down below 11.5V/23.0V, then the charge cycle starts all over again with step 1.
