Battery charger SMART 4 6/12V 4A SMART4

SMART CHARGER 4 is an inverter, intelligent and portable charger for 6 and 12-volt lead-acid, gel, AGM, MF, and EFB batteries with free electrolyte flow, intended for mechanical vehicles (petrol and diesel), motorcycles, motorboats, etc.

 

Automatic shutdown upon reaching the required voltage on the battery and automatic resumption of charging when the battery voltage drops.

 

7-stage charging process ensures optimal battery charging conditions. The automatic control system adjusts each of the 7 charging stages for correct battery charging:

 

STAGE 1 - diagnostics - analyses the battery and checks if it can accept charging current, prevents charging of a damaged battery

STAGE 2 - pre-charging - low voltage batteries are pre-charged with a small current, ensuring greater battery longevity

STAGE 3 - soft start - the charger gradually increases the charging current until full charging current is reached

STAGE 4 - CC1, CC2, CC3 (Constant Current) - fast charging. The charging current is set automatically depending on the battery's state of charge

STAGE 5 - CV (Constant Voltage) - charging to 14.6V. Intended for charging nearly fully charged batteries. It will finish charging the battery upon reaching 14.6V

STAGE 6 - Resting - ends the charging process when the battery is fully charged

STAGE 7 - Restoring - automatic battery monitoring. The charging process will resume when the battery voltage drops below 12.8V (for 12V batteries). The charger will restart the charging process beginning from stage 1.

 

Chargers have a microprocessor control system, LED indicators showing the charger's operating status:

 

SELECT switch for charging voltage 6/12 V depending on the battery's nominal voltage 2A - 6V and 4A - 12V

LED Power - indicates the charger is connected to the power supply

LED Charging - indicates the battery charging stage

LED Charged - indicates the end of charging

LED Error - indicates battery connection error, unrecognised battery, or incorrect charging voltage selection.
