Memory-function
The charger will return to the last charging mode when disconnected and reconnected. If this mode is
not compatible with the connected battery, the charger will automatically return to Standby-mode.
Defective Battery Detection And Recovery
Even if the battery voltage is very low, the charger tries to rescue the battery. If the battery voltage is
between 14V to 21V it is not clear whether a fully charged 12V battery or a deep-discharged 24V
battery is connected. The charging process automatically commences with a gentle impulse charge,
trying to reactivate a 24V battery until the voltage rises. This way, even batteries believed dead can be
made reusable. If voltage doesn´t rise over 21 within 2 hours, the "Defective-Battery"-symbol lights up
and the connected battery is considered as defect.
Zero-Volt-Battery-Charging
This function is used in lithium batteries. As lithium battery packs have Protection Circuit Modules (PCM),
the Output voltage is 0V when the PCM has activated. A very small pulse current is used to sense the
connection of the battery.
Maintenance / Trickle charging
After the battery has been fully charged, the charger automatically changes to trickle charging.
Depending on the measured voltage, the charging process is interrupted or the battery is maintained in
a fully charged condition with low charging currents. A battery can remain permanently connected to
the charger without damage or adverse effect on its performance. The trickle charge can be used to
maintain a battery.
Overheat-Protection
If the charger becomes too hot during charging, the power output is automatically reduced in order to
protect the device from damage.
Wrong Polarity: This symbol flashes if a battery was connected in reversed
polarity. Check the polarity and connection and reattach the charging cables.
Defective-Battery:
- As soon as the battery charger has been connected to the mains,
the charger analyses the connected battery: If the battery voltage
is lower than 2.0 V or higher than 28 V, the battery is not suitable
or defective and the "Defective-Battery"-symbol lights up.
- If the connected battery is charging in "RECOVER-12V"-Mode and
after 3 hours the battery´s voltage is still not higher than 12V the
battery is also considered as defective.
Not Connected: This symbol flashes if no battery is connected or the
connection is interrupted. Check the connection and reattach the charging
cables.
Battery-level:
This symbol will flash during the charging process. The bars indicate the
progress:
1 bar (20%), 2 bars (40%), 3 bars (60%), 4 bars (80%), 5 bars (90%)
If the symbol stops flashing, the battery is considered as fully charged and
the charger will switch automatically to "Maintenance / Trickle charging" to
keep the battery in a fully charged state.
