AUTOMATIC DETECTION OF BATTERY:
As soon as the battery charger has been connected to the mains, the charger
recognizes the battery based on the following criteria: If the battery voltage is
lower than 2.0 V or higher than 14 V, the battery is not suitable or defective.
The error message appears and flashing on the display.
NOTE:
Depending on the charging condition of the battery, the charger adapts the
charging currents to ensure optimum charging of the battery. Only during
the main charging phase, the battery is charged with the maximum charging
current. Shortly before the maximum charging capacity has been reached
the charging current is reduced. This ensures a gentle and best possible
charging up to the battery’s maximum capacity.
12 V Battery:
If the battery voltage is between 2.0 and 14.0 V, the battery is identified as a
12 V battery. By pressing the MODE key the 12 V charging program is started.
If the battery voltage does not rise to 10.5 V within 2 hours, the error
message appears and flashing on the display and returning to the
standby mode.
24 V battery:
If a battery voltage of between 14.0 V and 21 V is measured, this indicates
a critical range as at the lower voltage end. It is not clear whether it is a
fully charged 12 V battery (which could have a voltage of 14 V) or a deep-
discharged 24 V battery, the Step 2 Recovery will start by pulsing small
amounts of current. If the battery voltage does not rise to 21 V within 2
hours, the error message appears and flashing on the display and
returning to the standby mode.
