LITHIUM 12.8V MODE (14.5V 3.0A):
Long press 3sec. the MODE selection button, if the measured voltage is
between 11.6 V and 13.8 V the battery is identified as a Lithium (12.8V 4-cells
LiFePO4) to activate
mode.
Then if you do not take any further action, the electronic system will
automatically start the charging process together with the LCD display will
flash at (with a current of) 3.0A. If the process runs without any problems,
the LCD display will show the battery charging (bars will start flashing) until
the battery is charged. When the battery is fully charged, the battery icon
should be full and will stop flashing. The device now switches automatically
into maintenance charging mode.
0V battery charging.
This feature is used for zero volt batteries; it uses a very small pulse current
to sense the connection of the battery. This function is used in lithium
batteries, as lithium battery pack has Protection Circuit Modules (PCM),the
battery pack output is 0V when the PCM have actioned.
Overheating protection
If the appliance becomes too hot during charging, the power output is
automatically reduced. This protects the appliance from damage.
Trickle charging
Once the battery has been fully charged, the charger automatically changes
to trickle charging. Depending on the measured voltage, the charging is
interrupted or the battery is maintained in a fully charged condition with low
voltage currents (0.9A or 0.4A / 0.05A).
NOTE:
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.
