PERSONAL PRECAUTIONS AND SAFETY
B.
5. Remove all personal metal items such as rings, bracelets,
necklaces, and watches when working with a lead-acid
battery. A lead-acid battery can produce a short-circuit
current high enough to weld a ring (or the like) to metal,
causing a severe burn.
6. Take care not to drop a metal tool or other metal onto the
battery. Metal may cause sparking or short circuit the battery
or another electrical devise. Sparking may cause an
explosion.
7. Always operate battery charger in an open well ventilated
area.
8. NEVER smoke or allow a spark or flame in the vicinity of the
battery or engine. Batteries generate explosive gases!
1. WARNING: Wear complete eye protection and clothing
protection, when working with lead-acid batteries.
2. Make sure someone is within range of your voice or close
enough to come to your aid when you work with or near a
lead-acid battery.
3. Have plenty of fresh water and soap nearby for use if battery
acid contacts skin, clothing, or eyes. If battery acid contacts
skin or clothing, wash immediately with soap and water.
4. Avoid touching your eyes while working with a battery. Acid
particles (corrosion) may get into your eyes! If acid enters
your eye, immediately flood eye with running cold water for
at least 10 minutes. Get medical attention immediately.
GROUND AND AC POWER CORD CONNECTIONS
C.
Charger should be grounded to reduce the risk of electric shock.
Charger is equipped with an electric cord having an equipment
grounding conductor and a grounding plug. The plug must be
plugged into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances. This battery
charger is designed for use on a nominal 120 volt circuit and
has a grounded plug that looks like the plug illustrated in FIGURE 1 (A). This plug should be used in a grounded outlet. The
plug pins must fit the receptacle (outlet).
ADAPTER: A temporary adapter, as show in FIGURE 1 (B) and
(C), may be used to connect the charger plug to a two pole
receptacle (outlet), as shown in FIGURE 1 (B).
GROUNDING
SCREW
NOTE: The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.
FIGURE 1 GROUNDING METHODS
DANGER: Never alter the AC cord or plug provided. If it will not fit outlet, have a proper outlet installed by a qualified electrician.
Improper connection can result in a risk of an electrical shock. DANGER: Before using an adapter, as illustrated, be certain that the
center screw of the outlet plate is grounded. The green-colored rigid ear or lug extending from the adapter must be connected to a
properly grounded outlet. Make certain it is grounded. If necessary, replace original outlet cover plate screw with a longer screw that will

First connect the charger to the battery following instructions in section F and G.
Plug the charger power cord into AC outlet.
Set battery voltage switch to match the battery voltage, then switch the power switch to ON.
Select mode of operation, either MANUAL or AUTO (Automatic).
The charger begins in the MANUAL mode when first started, by default. If you wish to charge in the MANUAL mode, set the CHARGE
RATE and then the desired TIME of charge. If you select AUTO (Automatic), select your desired CHARGE RATE, 2, 15, OR 40 amps.
(See charge rate chart). The TIME does not have to be set in the AUTO (Automatic) mode.
5. Charging will now begin. By default, the meter will display the battery voltage. If you want amps displayed, simply press the VOLT/
AMP button.
6. If you selected MANUAL, you have the option of setting the time the battery will charge. If you do not set a time the maximum time
allowed for the charge rate selected will be automatically chosen by default. (See explanation of timer).
The TIMER has three clocks, one for each charge rate. For the 40 amp rate, the maximum time setting is 5 hours, set in increments of
1/2 hour. The 15 amp rate has a maximum time setting of 14 hours and the 2 amp setting has a maximum time setting of 18 hours. Both
the 10 amp and the 2 amp are set with time increments of 1 hour. You must press and depress the TIME button to advance the TIME
setting. Once you have begun charging, pressing the TIME button will tell you the remaining charge time.
If the battery is deeply discharged, below 1.5 volts, you must start the charging in the MANUAL mode and in the 2 amp setting. This will
bring the battery voltage up high enough to allow you to use the other features of the charger. You may use your voltmeter to read the
battery voltage.

Repeat until engine starts.
DO NOT try to crank a vehicle without a battery, as you may damage the vehicle's electrical system.
If the engine spins, but fails to start after several cranking attempts, there is a problem other than the starting system. Stop cranking the
engine until the other problem is found and corrected.
CAUTION: Excessive continuous cranking can damage a starter motor.
J.
CHARGING TIME REQUIRED
The automatic charging circuit will prevent overcharging a battery. When full charge is reached, the charging to the battery will be turned off and
the meter will display FULL.
When charging in the MANUAL mode, you must monitor the charging of the battery. Select the AMP display on the meter. When the amp reading is about
one half of the set charge rate, the battery is fully charged, stop the charging and disconnect from the battery. Overcharging can occur when using
the MANUAL mode. Refer to the Charge Rate Chart on page 4 and charging time formula below.
Determine the charge level of your battery with a hydrometer or electronic percent of charge tester. Determine the ampere hour rating of your battery. It
may be on the battery information label. If the battery is rated in Reserve Capacity, convert to ampere hour rating using the following formula:
Ampere Hour rating = (Reserve Capacity) + 16
(2)
Example: AH rating = (168 Reserve Capacity) + 16
(2)
or AH = 100
Use the following formula to determine the time of charge required: (AH x % of charge needed) divided by amp setting of the charger, times
1.25 = hours of charge:
Example: State of charge of the battery is 50%
Percent of charge needed is 100% - 50% = 50% (.50 decimal)
Ampere rating of the battery is 100AH
Charger setting is
10 amps
100 x .50

=
x 1.25
=
6.25 hours of charge needed
+ 1.00 hour more if charging a deep cycle battery

INDICATIONS OF A FULLY CHARGED BATTERY
A hydrometer reading of the specific gravity of the electrolyte (fluid) of the battery in good condition should be between 1.25 and 1.28.
When a battery reaches 80-85% of full charge, bubbles will appear on the surface of the fluid. As the battery nears full charge, bubbling
will become more vigorous.
The digital display Meter will display FULL when the battery is completely charged.
