SMART CHARGER 4 LCD 6/12V

Intelligent rectifier for charging WEL/GEL/MF/AGM batteries. 9-step charging process. LCD display. Power supply 230V. Charging voltage 6V/12V. Charging current 4A.

Technical parameters
SMART CHARGE 4 LCD  is an electronic charger for charging 6 and 12 volt lead-acid batteries:

WET  (liquid - acidic)
GEL  (gel)
MF  (maintenance-free)
AGM  (with fiberglass mat)
EFB  (for vehicles with Start-Stop system)
The rectifier has  a microprocessor control system and ensures automatic shutdown when the required battery voltage is reached and automatic resumption of charging after the battery voltage drops.

Cold battery charging function  : optimizes charging at very low temperatures (low temperatures may adversely affect the chemical structure of battery components).

LCD display
The rectifiers have a microprocessor control system and  an LCD display  that makes it much easier to monitor and adjust charging parameters.

Charging process
The 9-step charging process  ensures optimal battery charging conditions. The automatic control system will adjust each of the 9 charging stages to properly charge the battery:

STEP 1 - Diagnostic - analyzes the battery and checks whether it can accept the charging current; prevents charging of a damaged battery
STAGE 2 - Recovery charge - low voltage batteries are initially charged with a low current, but with an increased voltage; very discharged batteries can be restored to a usable state and this ensures a longer battery life, this step is skipped if the battery is minimally discharged and in good condition.
STEP 3 - Soft start - the rectifier gradually increases the charging current until the set charging current is reached
STEP 4 - Pulse charge - the battery is charged with a pulsed current (pulse fluctuations take place in the DC current range)
STAGE 5 - Reconditioning - preparatory stage for charging in the bulk charge stage
STEP 6 - Bulk charge – charging with a constant current to the previously set voltage (14.4÷14.7V)
STEP 7 - Absorption charge - after reaching the required battery charge level, it will change to constant voltage (CV) charging and the charging process will end
STEP 8 - Evaluation diagnostic - automatic monitoring of battery voltage after charging
STAGE 9 - Maintenance charge – the stage supporting the battery (float) and monitoring its condition; resumes charging at reduced current if necessary.
