Das charging device automatically goes through the
following stages:
Stage
1: Desulphation
The Desulphation stage may break down sulphation that occurs in batteries
that have been left flat for extended periods of time, returning them back
to full charge. Sulphation occurs when lead-sulphate hardens and clogs up
the battery cells.
Stage
2: Soft Start
A preliminary charge processes that gently introduces power to the battery.
This protects the battery and increases battery life.
Stage
3: Bulk
Bulk mode charges the battery at the maximum rate (constant current)
putting a large amount of power into the battery in a short amount of time.
This stage will charge the battery to approximately 80%, until the voltage
reaches 14.4 volts for 12V charger or 28.8 volts for 24V charger.
Bulk mode for the charging cycle. The start phase continues until the
battery‘s terminal voltage has risen above the set limit, at which point the
charger switches to bulk charging. If the terminal voltage has not passed
the voltage limit within the time limit, the charger switches to fault mode
and discontinues the charging. If so, the battery is faulty or its capacity is
too large.
