from –20°C to +45°C. A high temperature environment will lower the voltage and fre-
ezing condition is handled by higher voltage. A low temperature heightens the output
voltage, and hot condition is handled by lower voltage.
Voltage compensation
Because of some voltage drop in the cables, the actual voltage at the clamps of the
battery can be lower than the charger output voltage. A special circuitry inside the
unit will monitor the true input voltage to the battery and adjust the output voltage of
Reverse-polarity protection
This unit offers reverse-polarity protection under charging modes, the RED LED will
illuminate and the charging process will not start. If this happens, unplug immediately
from mains, connect the red clamp to positive (+) battery post, and black clamp to
negative (-) post, then plug into the mains power and the charging process will start.
Short-circuit protection
Should you accidentally touch the clamps together whilst the mains power is on, the
unit will not perform charging. Unplug from mains, disconnect and start the process
again being careful not to touch the clamps together.
Charge Memory
If power off on charging, MB3613 can automatically restart charging base on pre
-vious on previous power down status for battery and charging current.
ATTENTION: Once the clamp of charger is disconnected from the battery, this me-
mory is erased and the charging mode will need to be reselected.
