Page 9: Charging Cycle
Consult your battery manufacturer when in doubt. CHARGING CYCLE MULTI US 3300 operates in a four step fully automatic cycle. It starts the charging with an almost constant current (0.8A or 3.3A) until maximum voltage (14.4V or 14.7V) is reached. At this point the charger switches to constant voltage, and the current supply to the battery is gradually reduced. -
Page 10: Bulk Charging Time
Desulphation: Desulphation with pulsing for sulphated batteries. Bulk: Charging where about 80% of the energy is returned. The charger delivers an almost constant current until the battery voltage reaches the set level. Absorption: Charging up to almost 100%. The charge current tapers and the voltage is kept constant at the set level. -
