BATTERY TYPE BUTTON
Use this button to select the type of battery.
– Used in cars, trucks and motorcycles,
•
these batteries have vent caps and are often
marked "low maintenance" or "maintenance-
free". This type of battery is designed to
deliver quick bursts of energy (such as
starting engines) and has a greater plate
count. The plates are thinner and have
somewhat different material composition.
Standard batteries should not be used for
deep-cycle applications.
– The Absorbed Glass Mat
•
construction allows the electrolyte to be
suspended in close proximity with the
plate's active material. In theory, this
enhances both the discharge and recharge
efficiency. The AGM batteries are a variant
of Sealed VRLA (valve regulated lead-acid)
batteries. Popular uses include high-
performance engine starting, power sports,
deep-cycle, solar and storage batteries.
– The electrolyte in a GEL cell has a
•
silica additive that causes it to set up or stiffen.
The recharge voltages on this type of cell are
lower than those for other styles of lead-acid
battery. This is probably the most sensitive
cell in terms of adverse reactions to
WARNING: A spark near battery may cause
battery explosion.
CHARGING A BATTERY IN THE VEHICLE
1. Turn off all the vehicle's accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Set the ON/OFF switch to the OFF position.
5. Lay the AC/DC cables away from any fan
blades, belts, pulleys and other moving
parts that can cause injury.
6. For a negative-ground vehicle (as in
most vehicles), connect the charger's
POSITIVE (RED) clamp to the POSITIVE
(POS, P, +) battery post. Next, connect
the charger's NEGATIVE (BLACK) clamp
to the vehicle chassis or engine block,
away from the battery.
7. For a positive-ground vehicle, connect the
charger's NEGATIVE (BLACK) clamp to the
NEGATIVE (NEG, N, -) battery post. Next,
connect the charger's POSITIVE (RED)
clamp to the vehicle chassis or engine
block away from the battery. NEVER
connect any clamps to the carburetor, fuel
lines or sheet-metal body parts.
8. Connect the charger to an electrical outlet.
9. With the charger plugged in and connected
to the battery of the vehicle, set the ON/OFF
switch to the Boost or Charge/Maintain position.
10. Select the desired rate and battery type.

overvoltage charging. Gel batteries are best
used in VERY DEEP cycle application and
may last a bit longer in hot weather
applications. If the wrong battery charger is
used on a gel cell battery, poor performance
and premature failure will result.
TIMER BUTTON
The timer allows the battery to receive a
BOOST for a designated amount of time.
IMPORTANT: To accurately set the timer,
you must know the size of the battery (in
ampere hours) or reserve capacity (in
minutes) and the state of charge (see table
below). The time limit is 240 minutes.
12V Battery Reading
12.8 volts or more
12.2 to 12.7 volts
Less than 12.2 volts
To set the timer:
1. Press the DISPLAY BUTTON and choose
TIME.
2. Press the TIMER BUTTON to set the
appropriate time.
3. To turn off the timer, press the DISPLAY
BUTTON and choose a different setting.
11. If using Boost mode, set the DISPLAY
button to TIME, then use the TIMER
button to set the time, in minutes.
12. When disconnecting the charger, set
the ON/OFF switch to the OFF position,
disconnect the charger from the AC
power, remove the clamp from the vehicle
chassis, and then remove the clamp from
the battery terminal.
CHARGING A BATTERY
OUTSIDE OF THE VEHICLE
1. First, place battery in a well-ventilated area.
2. Set the ON/OFF switch to the OFF position.
3. Clean the battery terminals.
4. Connect a 24-inch long, 6-gauge (AWG)
insulated battery cable to the NEGATIVE
(NEG, N, -) battery post (i.e., jumper cable)
(not provided).
5. Connect the POSITIVE (RED) charger clamp
to the POSITIVE (POS, P, +) battery post.
6. Position yourself and the "negative post
extension" cable as far away from the
battery as possible, and connect the
NEGATIVE (BLACK) charger clamp to the
cable's free end.
7. Connect the charger to the electrical outlet.
8. With the charger plugged in and
connected to the battery of the vehicle,
set the ON/OFF switch to the Boost or
Charge/Maintain position.
