1) Diagnosis & Recovery
Initializes the recovery process for drained batteries by pulse charging with high & low current in order to restoring the battery capacity.

2) Bulk
80% of energy is returned in this phase of charging. Here charger performs in two states: High Rate Charging and Medium Rate Charging.

3) Absorption
In this phase complete charging up to almost 100% is achieved. Charger switches to trickle charge phase after sensing that the battery is truly fully charged.

4) Analysis
After absorption phase, charger analyses condition of battery for 5 minutes to confirm the battery whether can retain charge or not. Battery that cannot retain charge with warning indication by flashing of “ FAL ” on digital display.
 
5) Trickle Charge
Battery is fully charged and ready to use. If the battery needs more current, the charger will switch to Maintenance Charge phase.

Standby feature
When battery remains connected with vehicle’s wiring system, during the trickle mode, circuits continuously monitor the current drawn by the battery.

6) Maintenance Charge
As charger continuously monitors the terminal voltage in order to determine if a maintenance charging should be initiated. If the battery is loaded and/or terminal voltage falls below 12.8V (for 12V battery) or 25.6V (for 24V battery), the charger starts a maintenance cycle until voltage reaches to 14.4V (for 12V battery) , 16V (for 12V Lead-Calcium battery) or 28.8V (for 24V battery). The maintenance charging is discontinued.
