Connection to a battery outside a vehicle.
1. Make sure the AC Power Cord (#3) is not plugged in.
2. The battery will have two terminals. One should be marked POSITIVE, POS, P, OR +.
The Negative terminal should be marked NEGATIVE, NEG, N, OR -. To protect you by
keeping you further away from the battery, connect a battery cable (not included) that is
at least 24” long and #6 AWG (American Wire Gauge) to the NEGATIVE terminal of the
battery.
3. Connect the POSITIVE (red) Clamp (#2) from the charger to the POSITIVE terminal of
the battery.
4. Position yourself and the free end of the battery cable (not included) that is attached to
the NEGATIVE battery terminal, as far away as possible from the battery. While facing
away from the battery, connect the NEGATIVE (black) charger Clamp (#2) to the free
end of the battery cable (not included).
Charging
1. The charger must be set to the same voltage as the battery.
Settings:
The six volt setting (10A/6V) on the select switch is for charging medium to large 6 volt
batteries. It is a manual setting. After the battery is fully charged, the charger must be
disconnected to avoid damage. Charging time is 6 to 8 hours, and must be monitored throughout
the operation.
The two amp, 12 volt setting (2A/Auto) on the select switch is for charging small 12 volt
batteries or warming larger automotive batteries overnight to assist in cold weather starting. It
will not fully charge larger or deep cycle batteries. This setting is automatic. It will slow down
the charging rate when the battery reaches full charge. Charging time is a little longer on the
automatic setting as the unit tapers off slowly. It takes approximately 6-8 hours and it isn’t as
critical to monitor.
The ten amp, 12 volt setting (10A/12V) on the select switch is for charging medium to
large 12 volt batteries. This setting is automatic. It will slow down the charging rate when the
battery reaches full charge. Charging time is a little longer on the automatic setting as the unit
tapers off slowly. It takes approximately 6-8 hours and it isn’t as critical to monitor.
Small batteries: Lawn mower, motorcycle, or snowmobile type batteries have charge
rate limits. Always charge them on the two amp, 12 volt setting (2A/Auto) on the select switch.
Do not use this charger for charging small 6 volt batteries unless the manufacturer of the
battery states that the battery will withstand a 10 amp charge rate.
Note: More on manual charging times discussed on page 10.
Warning!! If the Reverse Connect light (see FIGURE 1) ever lights, immediately unplug the
charger and reconnect the clamps to the battery to alleviate the problem.
Note: Engine starting settings are covered on page 9.
2. When ready, set the select function switch (see FIGURE 1) to Charge and plug in the
charger to begin charging.
3. During charging, whether using the manual or automatic modes, it is important to monitor
the operation by checking the ammeter (see FIGURE 1).
Note: When the battery is charged the green charge complete light will turn on.
