Bulk Charging Time - CTEK MULTI US 3300 User Manual

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.
Pulse: Maintenance charge. The charging process ranges between 95% and 100%. The
battery receives a pulse if the voltage falls. This stage will keep your battery in a good
condition if it is not being used.
