BATTERY CHARGING INSTRUCTION
A spark near the battery may cause an explosion. Follow instructions carefully to reduce the risk of
spark near the battery.
1.
Connect the charger system to a wall receptacle strongly.
2.
Connect the alligator clips to battery terminals (red clip--->positive terminal; black
clip--->negative terminal) For dual output connection, Battery NEG- port is shared for two sets
of battery cables
3.
Position the AC and DC cords to reduce the risk of damage by a hood, door, or moving engine
part.
4.
Turn on the power switch which is located on the front panel/back panel of charger, then the
red LED lits and bi-color LED will confirm the charger's stage.
5.
Do not face the battery when making the connection.
6.
Once the battery is fully charged, disconnect the AC cord, remove the clip from the electrical
items and then remove the clip from the battery terminal.
7.
The battery maybe damaged if charging status LED cannot change to green after long time
charge.
8.
The battery charger was designed by aluminum housing with good thermal dissipation.
However, avoid touching the case for safety purpose because the temperature may reach to
about 50 degree C on the case when charging.
9.
After using battery for certain period of time, the increase of battery impedance will make the
charger unable to identify whether the battery is fully charged. In this case, the charger will
continue charging the battery with equalizer charge, which may cause over charge and reduce
the lifespan of battery. To prevent this from happening, whenever charging new batteries, it is
recommended to record the perfect charging time from “Charging End Time Setting.”
CAUTION: Keep the charger in a well ventilated, cool and open area. Do not block the vent
holes on the sides or the discharge openings of the cooling fan.
