APPENDIX A - CHARGING TIMES
To calculate the approximate charging time required to fully charge a battery, it is necessary to determine
the specific gravity (or, percent of battery charge) using a hydrometer. Use this technique, if battery vent
caps can be removed. Check each cell. If there is one cell with a very low specific gravity compared to
the other cells, there is probably a shorted cell in the battery. Replace the battery.
The following chart converts hydrometer readings into percent of charge values.

The times shown in the chart above are approximate and refer to an average automotive battery. For smaller
batteries, the charge time should be adjusted using the formula shown below and adding 1 hour to the time
calculated.
To estimate charging time for a discharged battery, divide the AH rating of the battery by the charge rate
selected. This is the number of hours required to recharge the battery. For example, a 50 AH (12 volt)
battery is discharged to 10 volts. How long should it be charged at the 15 Amp rate? Divide the 50 AH by
15 AH. The answer is approximately 3.5 hours. A six-volt battery is considered discharged when it reaches
5.0 VDC. Always round up the charge time by 25% to ensure full charge. In most cases, battery recharge
times will vary depending on the age and condition of the battery. Smaller batteries should be charged at
the lower rate (2 Amps) and add an extra hour to charge time.

PERSONAL PRECAUTIONS AND SAFETY
1. Someone should be within range of your voice or close enough to come to your aid when you work near
a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching eyes while working with a battery.
Acid, acid particles or corrosion may get into eyes. Immediately flood eye with running cold water for at
least 10 minutes and get medical attention immediately.
4. If battery acid contacts skin or clothing, wash immediately with soap and water.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery
or other electrical part that may cause explosion.
7. Remove 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.
GROUND AND AC POWER CORD CONNECTIONS
The charger should be grounded to reduce the risk of electric shock. The charge 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 electric codes and ordinances.
DANGER - NEVER alter an AC cord or plug. If the plug will not fit the outlet, have a proper outlet installed
by a qualified electrician. Improper connection can result in a risk of electric shock.
The battery charger is for use on a nominal 120 volt AC circuit, has a grounding plug that looks like the
plug illustrated in Figure 1. A temporary adapter, which looks like a the adapter in figures 1b and 1c may
be used to connect this plug to a two pole receptacle as shown in figure 1b, if a properly grounded outlet is
not available. The temporary adapter should only be used until a properly grounded outlet can be installed
by a qualified electrician.
DANGER - Before using the 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 the original outlet cover plate with a
longer screw that will secure the adapter ear or lug to the outlet’s cover plate and make ground connection
to grounded outlet.

PREPARING TO CHARGE
1. Determine voltage of battery by referring to car owner’s manual and make sure that output voltage
selector switch is set at correct voltage.
2. If it is necessary to remove battery from vehicle to charge, or to clean terminals, always remove grounded
terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
4. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This
helps purge excessive gas from cells. Do not overfill. For a battery without cell caps, carefully follow
manufacturer’s recharging instructions.
5. Study all battery manufacturers’ specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
6. Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully
blown away by using a piece of cardboard or other nonmetallic material as a fan.
7. Charge battery initially at the 2 Amp (lowest) rate.
CHARGER LOCATION
1. Locate charger as far away from battery as cables permit.
2. Never place charger directly above battery being charged; gases from battery will corrode and
damage charger.
3. Never allow battery acid to drip on charger when reading gravity or filling battery.
4. Do not operate charger in a closed-in area or restrict ventilation in any way.
5. Do not set a battery on top of charger.
6. If battery charger is used in a commercial garage or aircraft hangar application or in an area where
combustible gas fumes can accumulate, the battery charger must be located at least 18 inches above the
floor as stated by the National Electrical Code.
DC CONNECTION PRECAUTIONS
1. Connect and disconnect DC output clips only after removing AC cord from electric outlet.
2. Never allow clips to touch each other.
3. Attach clips to battery posts and twist or rock back and forth several times to make a good connection.
This tends to keep clips from slipping off terminals and helps to reduce risk of sparking.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR BATTERY MAY CAUSE
BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:
a. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than
NEGATIVE (NEG, N,-) post.
d. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded
to chassis (as in most vehicles), see (e). If positive post is grounded to the chassis, see (f).
e. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS,
P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) clip to vehicle chassis or engine
block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts.
Connect to heavy gauge metal part of the frame or engine block.
f. For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to NEGATIVE
(NEG, N, -) ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine
block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts.
Connect to a heavy gauge metal part of the frame or engine block.
g. When disconnecting charger, turn switches to off, disconnect AC cord, remove clip from vehicle
chassis, and then remove clip from battery terminal.

service. Follow these simple steps to maintain the charger in optimum condition:
• After each use, clean the battery charger clamps - be sure to remove any battery fluid that will cause
corrosion of the copper clamps.
• Clean the outside case of the charger with a soft cloth and, if necessary, mild soap solution.
• Keep the charger cords loosely coiled during storage to prevent damage to the cords. Do not use the
charger if cords or clamps have been damaged in any way - call Vector Technical Support Department at
(954) 584-4446 or toll free at (866)-584-5504 for details on replacing cords and clamps.
TROUBLESHOOTING
VERY CO LD BATTERY
If the battery to be charged is extremely cold (in temperatures less than freezing - 0ºC/ 32ºF) it cannot
accept a high rate of charge so the initial charge rate will be slow. The rate of charge will increase as
the battery warms.
WARN IN G: DO N O T attempt to charge a frozen battery.
SULFATED BATTERY
When batteries are left in a discharged state for a long period of time, they become “sulfated”. Sulfated
batteries cannot accept a high rate of charge since the internal plates are coated with lead sulfate. To see if
a battery in this condition can be “saved”, take it to a service station or battery distributor for professional
evaluation and/ or service.
SHO RT-CIRCUITED BATTERY
• If the battery being charged has been short-circuited, the ammeter will show that the battery has zero
charge level, and that the charger is operating at peak amperage. If, after 5 minutes charging time, the
ammeter reading has not decreased, unplug the charger and discontinue the charging process.
• Using a voltmeter, determine the voltage of the battery and if it is under 12 volts (under 6 volts for 6 volt
batteries), the battery is probably beyond repair or recharging, and will need to be replaced.
• If the voltage is over 12 volts (over 6 volts for 6 volt batteries), reconnect the charger and resume the
charging process for another 15-20 minutes. If, after that time, the ammeter still has not moved towards a
lower reading, repeat the voltmeter test. If the reading is still over 12 volts (or over 6 volts for 6 volt batter-
ies), there is a problem with the battery that requires professional service or replacement.
N O AMMETER READIN G
• Make sure that the charger is powered by a “live” 110/ 120-volt grounded AC outlet.
• Unplug charger and check battery connections - ensure that there is a good connection with the battery
terminal and/ or vehicle chassis.
• Check to be sure that the battery is not sulfated.
• Check that the correct charge rate has been selected for the battery being charged.
• Ensure that enough charging time has been allowed for - check table in Appendix for approximate
charging times.
• See Pre-charge Battery Activation.
AMMETER DISPLAYS A READIN G, BUT BATTERY IS N O T ACCEPTIN G CHARGE
• First, make sure that battery is capable of being charged - ensure that it is not sulfated or damaged.
• Refer to Charging Time Table in Appendix to ensure that enough time is being allowed to charge
the battery.

sheet-metal body parts: connect only to a heavy gauge, stable metal part of the frame or engine block.
N O TE: If there is any problem connecting the charger clamps to the battery terminals, contact the Vector
Technical Support Department at (954) 584-4446 or toll free at (866)-584-5504 for assistance.
d) Plug battery charger power cord into grounded AC power outlet and refer to Appendix A at the end
of this document for approximate charging times.
e) When charging is completed, disconnect cables and clamps in reverse order from which they were
connected.
N O TE: Use of Extension Cords If it is necessary to use an extension cord, as is often the case, observe the
following important safety information:
• Before using any extension cord, ensure that the wire size is at least 16 AWG or larger and 14 AWG for
longer than 100 feet.
• Use only a good quality, good condition, UL-approved extension cord, and ALWAYS connect charger to
the extension cord before plugging the extension cord into a 110/ 120-volt AC power outlet. The use of a
poor quality extension cord or one that is not in good repair could cause fire and/ or electric shock.
• Use a three-wire extension cord with a 3-prong plug and 3-conductor socket.
CHARGING IF BATTERY IS OUTSIDE OF VEHICLE
Set charger’s Charge Rate Selector switch to appropriate setting according to battery size. Make sure the
Charge/ Start switch is in the Charge position.
a) Check polarity of battery posts- For top-mounted battery connectors, the positive post (marked POS,
P, +) usually has a larger diameter than the Negative battery post (marked NEG, N, -). For
side-mounted battery connections the Positive terminal is red, the Negative terminal is black.
b) Attach a 24-inch (minimum length) 6 AWG insulated battery cable to the Negative battery post
(marked NEG, N, -).
c) Connect the Positive (RED) battery clamp to the Positive battery connector (marked POS, P, + or red).
d) Stand as far back from battery as possible, and do not face battery when making final connection.
e) Carefully connect the Negative (BLACK) charger clamp to the free end of the battery cable connected
to the negative terminal. Connect the charger’s power cord to a grounded 110/ 120-volt AC power
outlet, and refer to section 8 for approximate charging times.
f) When charging is completed, disconnect cables and clamps in reverse order from which they were
connected.
CHARGING TIMES
The VEC078 is a fully automatic battery charger while charging 12 volt batteries. It automatically adjusts the
charge rate as the battery becomes charged and stops charging when the battery is fully charged. If you
require some estimate of the time it takes to charge a battery refer to Appendix A for these details.
ENGINE START
The Engine Start function can supply up to 100 amps of current during engine starting. This function is pro-
tected by an automatic reset protector and there is a five-second limit at this output level. Follow all precau-
tions as if charging a battery in a vehicle, except that the Charge/ Start Switch is placed in the Start position
and the Charge Rate Switch is placed in the Engine Start position. DO NOT MAKE BATTERY AND CHASSIS
CONNECTIONS WITH CHARGER PLUGGED INTO AC. Make the final connection to battery and chassis
and plug in the charger. Immediately crank the engine in three-second bursts until it starts. Disconnect the
charger’s AC connection first and then the chassis and battery connections. If the engine fails to start, you
may change switch positions and charge the battery without disconnecting the charger from AC.
After charging, if the charger is already powered and connected to the battery, you may safely move the
charger’s switches to the Start and Engine Start positions without disconnecting the charger from AC. After
the engine starts, disconnect AC, then the chassis and battery connections.

The Charge/ Start Selector switch in the Start position protects the Ammeter from reading excessive current.
When the Charge position is selected, the Ammeter reads charge current for both 12 volt and 6-volt settings.
See Figure 4.
FIGURE 4
AMMETER AND INDICATORS
The ammeter is the colored (red, green and blue) meter on the front of the unit. It displays the current flowing
from the charger to the battery, in amperes. See Figure 5.
FIGURE 5
When starting to charge a battery, the current will depend on the battery’s percent of charge. The actual
current will usually be lower than the current selected on the charger’s switch, unless the battery is severely
discharged. As the battery charge level increases, the current reduces.
The ammeter is intended to show how the charging process is proceeding, it should not be used to determine
the level of battery charge - this should be done using a hydrometer or a voltmeter.
Typically 12.6 VDC is considered full charge for a 12 volt battery if the voltage is measured one hour after

higher, so it needs to rest after charging to measure actual state of charge.
Below the Ammmeter is an incorrect polarity indicator that lights when incorrect polarity is sensed. It is
marked REVERSE. See figure 6a. It indicates that the charger to battery connection is reversed and it must be
reconected before charging can begin. This feature only operates when at least 4 volts or higher voltage
remains in the battery to be charged. This feature is active for both 6 and 12 volt batteries.
The charger’s built-in circuitry automatically taper charges the 12 volt battery as it approaches full charge
and then discontinues charging when the battery reaches full charge. This is the automatic feature. When
the battery is fully charged the 12 Volt FULL indicator lights. See Figure 6B the 12V FULL indicator and
Polarity indicator. Note that the automatic off feature only operates during 12 volt charging; six volt
charging is manual.

CIRCUIT BREAKER
This battery charger has an internal self-resetting circuit breaker automatic reset protector that protects the
charger from temporary overloads. When it operates it makes a clicking sound. You will see the ammeter
reduce to zero when the breaker is open. After a cool-down period, the breaker will automatically close and
the ammeter will show a high rate of charge. If the breaker continues to cycle every few minutes, reduce
charge rate or discontinue charging.
PRE-CHARGE ACTIVATION
CAUTIO N : Be aware that a fully charged battery will also cause a low Ammeter reading. Attempting
pre-charge activation of a fully charged battery may cause explosion - make sure that battery
really is discharged, before using this procedure.
Pre-charge activation is the term for the time it takes before a battery begins to accept a measurable rate of
charge - it can be as long as 4-8 hours from the time the charging process begins.
Pre-charge activation is indicated if the ammeter reading is zero and a hydrometer or voltmeter reading
shows that the battery is fully discharged.
N O TE: The newer, high-calcium-type 12 Volt DC batteries may need pre-charge activation if their charge has
been allowed to drop to a very low level. When deeply discharged, this type of battery will provide
only a very low voltage output and will draw less than 1 amp during the recharging process, until
activated.
CHARGING IF BATTERY IS INSTALLED IN A VEHICLE
a) Set charger’s Charge Rate Selector switch to appropriate setting according to battery size. Make sure
the Charge/ Start switch is in the Charge position.
b) Check polarity of battery posts - For top-mounted battery connectors, the Positive post (marked POS, P, +)
usually has a larger diameter than the Negative battery post (marked NEG, N, -). For side-mounted
battery connectors, the terminals are marked Positive -red and Negative -black.
c) Attach charger clamps to battery connections, as follows, ensuring a good connection (if there is a
mistake, the Reverse Polarity Indicator will light): NEGATIVE-GROUNDED VEHICLE: Connect the POSITIVE
(RED) charger clamp to the POSITIVE (POS, P, +) ungrounded battery terminal. Then, connect the
NEGATIVE (BLACK) charger clamp to the vehicle chassis, or the engine block (away from the battery).
Do not connect the clamp to the carburetor, fuel lines, or sheet-metal body parts: connect only to a heavy
gauge metal part of the frame or engine block. N O TE: NEGATIVE-GROUNDED type systems are the
most common in today’s vehicles.
PO SITIVE-GRO UN DED VEHICLE: Connect the NEGATIVE (BLACK) charger clamp to the NEGATIVE
(NEG, N, -) ungrounded battery post. Then, connect the POSITIVE (RED) battery clamp to the vehicle
chassis or engine part (away from the battery). Do not connect the clamp to the carburetor, fuel lines, or
