9) SAFETY FEATURES

• The charger is safe against user errors and provides optimal condition without damage.
• No risk of over-charging!
• The charger will not damage vehicle electronics.
Description
Diagnostic function automatically checks battery status (detects voltage).
Charging 80% of the energy
1) High rate charging
Charger delivers constant current of 3.8 A until the voltage reaches to 12.8 V.
2) Medium rate charging
Charger delivers constant current of 3.0 A until the voltage reaches to 14.1 V.
Since current is not delivered at highest constant level, charger will minimize the heating up of the battery, and hence
will eliminate the build up of gases. This ensures more efficient and safer performance.
Charging up to almost 100%
Use of a constant current of 3.8 A for extended periods of time risks gasing the battery.
Therefore a constant low charging current is given at 0.8 A to raise voltage from 14.1 V to 14.4 V.
Charger switches to trickle charge phase after sensing that the battery is truly fully charged.
Battery is fully charged and ready to use.
The battery will signal to the charger and will only take enough current to sustain small loads such as alarms or current
leaks in the vehicle wiring circuit.
Very low current of 100 mA is given to the battery. When voltage drops below 12.8 V, monitoring circuit senses that
battery needs more current to maintain its charge than available in trickle charge phase. The charger switches to
maintenance charge phase.
If the battery is loaded and/or terminal voltage falls below 12.8 V, the charger starts a maintenance charging pulse at
constant 0.8 A until voltage reaches to 14.4 V.
The maintenance charging is discontinued. Cycle of trickle charging and maintenance charging is repeated indefinitely
to keep battery in good condition when it is not in use and enables charger to be left connected indefinitely.
