BATTERY CHARGING
1. First connect the charger to the battery following instructions in section F and G.
2. Plug the charger power cord into AC outlet.
3. Set battery voltage switch to match the battery voltage, then switch the power switch to ON.
4. 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.
I.
ENGINE START
Engine Start:
ONLY ACTIVE IN THE MANUAL MODE. DO NOT CRANK ENGINE IN THE AUTOMATIC MODE.
1. Connect the charger to the battery following the instructions in sections F and G.
2. Plug the charger power cord into the 120 v 60 hz AC outlet.
3. Set the battery voltage selector switch to match the voltage of the battery, then switch the power switch to the ON position.
4. The charger will be in the MANUAL mode, indicated by MAN on the meter display.
5. Press START button and observe RDY on the display meter. The charger is now ready to have the engine cranked.
6. Crank the engine. Cranking is limited to 5 seconds, then automatically switches to the 15 amp charge rate for 5 minutes. The meter
will display WAIT. After the five minutes have expired, the meter will again display RDY and you may crank the engine once more.
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 theAMP 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
10
=
x 1.25
=
6.25 hours of charge needed
+ 1.00 hour more if charging a deep cycle battery
7.25 hours total for 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.

B. Make sure that the AC outlet is "LIVE." Check by plugging in a lamp.
2. Meter displays CHK BAT
A. Have a serviceman, at your neighborhood garage, check that the battery is capable of taking a charge, it may be damaged or
sulfated.
B. Make sure you have selected the proper charge voltage for the battery being charged.
C. After unplugging charger, check the connections at the battery. Make sure the clips are making good contact.
D. If the battery voltage is below 1.5 volts and you were charging in automatic, the display will read CHK BAT. Try to bring the battery
voltage up above the needed 1.5 volts by selecting the MANUAL mode and the 2 amp setting. This should bring the battery voltage
to the needed voltage in a few minutes.
3. Vehicle will not start in ENGINE START
A. Unplug the charger and check the connections at the battery.
B. You must wait until the meter read "RDY." The charger may still be in the "WAIT" mode.
C. The thermal protector may have tripped and needs a little longer to close. Wait a little longer and retry.
D. If the engine turns over, but doesn't start, the problem is with the vehicle, not the charger. Have the vehicle problem resolved
before you try to crank the engine again.
