IMPORTANT SAFETY INSTRUCTIONS1.
SAVE THESE INSTRUCTIONS – The NAPA 85-435 offers a wide range1.1
of features to accommodate your needs. This manual will show you how
to use your charger safely and effectively. Please read, understand and
follow these instructions and precautions carefully, as this manual contains
important safety and operating instructions.
WARNING1.2 : Pursuant to California Proposition 65, this product contains
chemicals known to the State of California to cause cancer and birth de-
fects or other reproductive harm.
Do not expose the charger to rain or snow.1.3
Use only recommended attachments. Use of an attachment not recom-1.4
mended or sold by the battery charger manufacturer may result in a risk of
re, electric shock or injury to persons or damage to property.
To reduce the risk of damage to the electric plug or cord, pull by the plug1.5
rather than the cord when disconnecting the charger.
An extension cord should not be used unless absolutely necessary. Use of1.6
an improper extension cord could result in a risk of re and electric shock.
If an extension cord must be used, make sure:
That the pins on the plug of the extension cord are the same number,•
size and shape as those of the plug on the charger.
That the extension cord is properly wired and in good electrical condi-•
tion.
That the wire size is large enough for the AC ampere rating of the char-•
ger as specied in the table in Section 8.2.
Do not operate the charger with a damaged cord or plug; take it to a quali-1.7
ed service person. (Call customer service at: 1-800-621-5485.)
Do not operate the charger if it has received a sharp blow, been dropped1.8
or otherwise damaged in any way; take it to a qualied service person.
(Call customer service at: 1-800-621-5485.)
Do not disassemble the charger; take it to a qualied service person when 1.9
service or repair is required. Incorrect reassembly may result in a risk of
re or electric shock. (Call customer service at: 1-800-621-5485.)
To reduce the risk of electric shock, unplug the charger from the outlet1.10
before attempting any maintenance or cleaning. Simply turning off the
controls will not reduce this risk.
WARNING – RISK OF EXPLOSIVE GASES.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGER-
OUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NOR-
MAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME
YOU USE THE CHARGER.

•2 •
TO REDUCE THE RISK OF A BATTERY EXPLOSION, FOLLOW THESE
INSTRUCTIONS AND THOSE PUBLISHED BY THE BATTERY MANU-
FACTURER AND THE MANUFACTURER OF ANY EQUIPMENT YOU
INTEND TO USE IN THE VICINITY OF THE BATTERY. REVIEW THE
CAUTIONARY MARKINGS ON THESE PRODUCTS AND ON THE
ENGINE.
PERSONAL PRECAUTIONS2.
Consider having someone close enough by to come to your aid when you2.1
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts2.2
your skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles and pro-2.3
tective clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, immediately wash the area2.4
with soap and water. If acid enters your eye, immediately ood the eye
with cold running water for at least 10 minutes and get medical attention
right away.
NEVER smoke or allow a spark or ame in the vicinity of a battery or 2.5
engine.
Be extra cautious to reduce the risk of dropping a metal tool onto the bat-2.6
tery. It might spark or short-circuit the battery or other electrical part that
may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces and2.7
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.
Use this charger for charging LEAD-ACID batteries only. It is not intended2.8
to supply power to a low voltage electrical system other than in a starter-
motor application. Do not use this battery charger for charging dry-cell
batteries that are commonly used with home appliances. These batteries
may burst and cause injury to persons and damage to property.
NEVER charge a frozen battery.2.9
NEVER overcharge a battery.2.10
PREPARING TO CHARGE3.
If it is necessary to remove the battery from the vehicle to charge it, al-3.1
ways remove the grounded terminal rst. Make sure all of the accessories
in the vehicle are off, to prevent arcing.
Be sure the area around the battery is well ventilated while the battery is3.2
being charged.

•3 •
Clean the battery terminals before charging the battery. During cleaning,3.3
keep airborne corrosion from coming into contact with your eyes, nose
and mouth. Use baking soda and water to neutralize the battery acid and
help eliminate airborne corrosion. Do not touch your eyes, nose or mouth.
Add distilled water to each cell until the battery acid reaches the level3.4
specied by the battery manufacturer. Do not overll. For a battery without
removable cell caps, such as valve regulated lead acid batteries (VRLA),
carefully follow the manufacturer’s recharging instructions.
Read, understand and follow all instructions for the charger, battery,3.5
vehicle and any equipment used near the battery and charger. Study all of
the battery manufacturer’s specic precautions while charging and recom-
mended rates of charge.
Determine the voltage of the battery by referring to the vehicle owner’s3.6
manual and make sure that the output voltage selector switch is set to the
correct voltage. If the charger has an adjustable charge rate, charge the
battery in the lowest rate rst.
Make sure that the charger cable clips make tight connections.3.7
CHARGER LOCATION4.
Locate the charger as far away from the battery as the DC cables permit.4.1
Never place the charger directly above the battery being charged; gases4.2
from the battery will corrode and damage the charger.
Do not set the battery on top of the charger.4.3
Never allow battery acid to drip onto the charger when reading the electro-4.4
lyte specic gravity or lling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in4.5
any way.
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after setting all of the5.1
charger switches to the “off” position and removing the AC plug from the
electrical outlet. Never allow the clips to touch each other.
Attach the clips to the battery and chassis, as indicated in steps 6.5, 6.65.2
and 7.2 through 7.4.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN6.
VEHICLE.
A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Position the AC and DC cables to reduce the risk of damage by the hood,6.1
door and moving or hot engine parts.
Stay clear of fan blades, belts, pulleys and other parts that can cause6.2
injury.

•4 •
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery 6.3
post usually has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chas-6.4
sis. If the negative post is grounded to the chassis (as in most vehicles),
see step 6.5. If the positive post is grounded to the chassis, see step 6.6.
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from 6.5
the battery charger to the POSITIVE (POS, P, +) ungrounded post of the
battery. Connect the NEGATIVE (BLACK) clip to the vehicle chassis or
engine block away from the battery. Do not connect the clip to the carbure-
tor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal
part of the frame or engine block.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip 6.6
from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post
of the battery. Connect the POSITIVE (RED) clip to the vehicle chassis or
engine block away from the battery. Do not connect the clip to the carbure-
tor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal
part of the frame or engine block.
When disconnecting the charger, turn all switches to off, disconnect the6.7
AC cord, remove the clip from the vehicle chassis and then remove the
clip from the battery terminal.
See CALCULATING CHARGE TIME for length of charge information.6.8
FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE.7.
A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery 7.1
post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery 7.2
cable to the NEGATIVE (NEG, N, -) battery post.
Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) 7.3
post of the battery.
Position yourself and the free end of the cable you previously attached to7.4
the NEGATIVE (NEG, N, -) battery post as far away from the battery as
possible – then connect the NEGATIVE (BLACK) charger clip to the free
end of the cable.
Do not face the battery when making the nal connection.7.5
When disconnecting the charger, always do so in the reverse order of the7.6
connecting procedure and break the rst connection while as far away
from the battery as practical.
A marine (boat) battery must be removed and charged on shore. To 7.7
charge it onboard requires equipment specially designed for marine use.

Battery Type Switch
Use this button to set the type of battery to be charged.
Regular• – Set the button to STARTING BATTERY. This battery type is
usually 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 have a greater plate count. The plates will also
be thinner and have somewhat different material composition. Regular
batteries should not be used for deep cycle applications.
Deep-Cycle• – Set the button to DEEP CYCLE/GEL BATTERY. Deep-
cycle batteries are usually marked as “Deep-Cycle” or “Marine”. Deep-
cycle batteries are usually larger than the other types. This type of
battery has less instant energy but somewhat greater long-term energy
delivery than regular batteries. Deep cycle batteries have thicker plates
and can survive a number of discharge cycles.
AGM• – Set the button to DEEP CYCLE/GEL BATTERY. The Absorbed
Glass Matt 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 efciency. Actually, 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 battery. AGM batteries are typically good deep
cycle batteries and they deliver best life performance if recharged be-
fore the battery drops below a 50 percent charge. If these AGM batter-
ies are completely discharged, the cycle life will be around 300 cycles.
This is true of most AGM batteries rated as deep cycle batteries.
GEL• – Set the button to DEEP CYCLE/GEL BATTERY. The Gel Cell
is similar to the AGM style because the electrolyte is suspended, but
different because technically the AGM battery is still considered to be a
wet cell. 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 the other styles of lead acid battery. This is probably the most sen-
sitive cell in terms of adverse reactions to over-voltage charging. Gel
Batteries are best used in VERY DEEP cycle application and may last
a bit longer in hot weather applications. If the incorrect battery charger
is used on a Gel Cell battery, poor performance and premature failure
is certain.
Charge Rate Selector Switch
Use the Charge Rate selector switch to select the charge rate or engine
starting setting you require.
2A Slow Charge Rate• – Intended for charging small batteries such as
those commonly used in garden tractors, snow mobiles and motorcy-
cles. NOTE: The 2A rate is not to be used as a trickle charger for larger
batteries.
10A Fast Charge Rate• – Use for charging automotive, marine and
deep-cycle batteries. Not intended for industrial applications.

•8 •
55A Engine Start• – Provides 55 amps for cranking an engine with a
weak or run down battery. Always use in combination with a battery.
OPERATING INSTRUCTIONS12.
Charging
Connect the battery following the precautions listed in Sections 6 and1.
7.
Select the appropriate settings for your battery.2.
Connect the AC power following the precautions listed in Section 8.3.
Automatic Charging Mode
When an Automatic Charge is performed, the charger switches to the
Maintain Mode (see below) automatically after the battery is charged.
Completion of Charge
Charge completion is indicated by the FULL CHARGE (green) LED. When
lit, the charger has stopped charging and switched to the Maintain Mode
of operation. If the 12V DEEP CYCLE battery type was selected, the FULL
CHARGE (green) LED comes on when the battery is charged enough for
normal use.
Maintain Mode
When the FULL CHARGE (green) LED is ashing, the charger has started
Maintain Mode. In this mode, the charger keeps the battery fully charged
by delivering a small current, when necessary. If the battery voltage drops
below a preset level, the charger will go back into Charge Mode until the
battery voltage returns to the full charge level, at which point the charger
will return to Maintain Mode. The voltage is maintained at a level deter-
mined by the BATTERY TYPE selected.
NOTE: The charger automatically switches between Charge Mode and
Maintain Mode as necessary. The FULL CHARGE (green) LED will cycle
on when the battery is at full charge and off when the voltage drops below
a preset level and the charger goes into Charge Mode. This cycle will
continue, and the FULL CHARGE (green) LED will ash for longer periods
of time as the battery becomes more fully charged.
Using the Engine Start feature
Your battery charger can be used to jumpstart your car if the battery is low.
Follow these instructions on how to use the ENGINE START feature.
IMPORTANT: Follow all safety instructions and precautions for charg-
ing your battery. Wear complete eye protection and clothing protection.
Charge your battery in a well-ventilated area.
IMPORTANT: Using the ENGINE START feature WITHOUT a battery
installed in the vehicle could cause damage to the vehicle’s electrical
system.

Crank the engine until it starts or 5 seconds pass. If the engine does4.
not start, wait 3 minutes before cranking again.
NOTE: During extremely cold weather, or if the battery is under 2 volts,
charge the battery for 5 minutes before cranking the engine.
If the engine fails to start, charge the battery for 5 more minutes before5.
attempting to crank the engine again.
After the engine starts, unplug the AC power cord before disconnecting6.
the battery clips from the vehicle.
Clean and store the charger in a dry location.7.
NOTE: If the engine does turn over, but never starts, there is not a prob-
lem with the starting system; there is a problem somewhere else with
the vehicle. STOP cranking the engine until the other problem has been
diagnosed and corrected.
Charging Tips
Read this entire manual before using your battery charger. The following
tips serve only as a guide for specic situations.
If your vehicle won’t start• – It is not necessary to fully charge your
battery to start a vehicle. When the battery’s charge is 77% or more, the
battery has usually been charged enough for the vehicle to start and
operate normally. If operating the vehicle continuously for an extended
period (such as a long drive), the vehicle’s charging system should
charge the battery back to normal during that period. If the vehicle will
only be operated for a short period (short drive), the battery might need
to be charged again before it could start the vehicle again.
Completing an interrupted charge• – Once the battery has reached
85% charge; if the charging process is interrupted and restarted, the
charger could go straight into Maintain Mode. However, if the original
charge was started using the 10A rate, the charge can often be com-
pleted using the 2A rate.
CALCULATING CHARGE TIME13.
Use the following table to more accurately determine the time it will take to
bring a battery to full charge. First, identify where your battery ts into the
chart.
Cold cranking amps (CCA) is a measurement of the number of amps a
battery can deliver at 0°F for 30 seconds and not drop below 7.2 volts. So
a high CCA battery rating is good especially in cold weather.

•10 •
Reserve Capacity (RC) is a very important rating. This is the number of
minutes a fully charged battery at 80°F will discharge 25 amps until the
battery drops below 10.5 volts.
An amp hour (AH) is a rating usually found on deep cycle batteries. If a
battery is rated at 100 amp hours it should deliver 5 amps for 20 hours, 20
amps for 5 hours, etc.
NR means that the charger setting is NOT RECOMMENDED.
Find your battery’s rating on the chart below, and note the charge time
given for each charger setting. The times given are for batteries with a
50% charge prior to recharging. Add more time for severely discharged
batteries.

MAINTENANCE INSTRUCTIONS14.
Before performing maintenance, unplug and disconnect the battery char-14.1
ger (see Sections 6, 7 and 8).
After use, unplug the charger and use a dry cloth to wipe all battery corro-14.2
sion and other dirt or oil from the terminals, cords, and the charger case.
Servicing does not require opening the unit, as there are no user-service-14.3
able parts.
STORAGE INSTRUCTIONS15.
Store the charger unplugged, in an upright position. The cord will still con-15.1
duct electricity until it is unplugged from outlet.
Store inside, in a cool, dry place (unless you’re using an on-board Marine 15.2
Charger).
Do not store the clips on the handle, clipped together, on or around metal,15.3
or clipped to cables.

•11 •
TROUBLESHOOTING16.
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
The charger is making an
audible clicking sound. Circuit breaker is cycling.
Battery is defective.
Shorted battery cables or
clips.
Severely discharged bat-
tery, but otherwise it is a
good battery.
Reverse connections at
battery.
The settings may be wrong.
Check the charger settings.
Have the battery checked.
Circuit breaker cycles when
current draw is too high.
Check for shorted cables or
clips and replace if neces-
sary.
The battery may not want
to accept a charge due to
a run-down state. Allow
charging to continue until
battery has a chance to
recover sufciently to take
a charge. If more than 20
minutes, stop charging and
have the battery checked.
Shut the charger off and
correct the lead connec-
tions.
Charger makes a loud
buzz or hum. Transformer laminations vibrate (buzz). No problem, this is a normal condition.
Short or no start cycle
when cranking engine. Drawing more than 55 amps (12V).
Failure to wait 3 minutes
(180 seconds) between
cranks.
Clips are not making a
good connection.
AC cord and/or extension
cord is loose.
No power at receptacle.
The charger may be over-
heated.
Battery may be severely
discharged.
Crank time varies with the
amount of current drawn. If
cranking draws more than
55 amps, crank time may be
less than 3 seconds.
Wait 3 minutes of rest time
before the next crank.
Check for poor connection
at battery and frame.
Check power cord and
extension cord for loose
tting plug.
Check for open fuse or
circuit breaker supplying AC
outlet.
The thermal protector may
have tripped and needs a
little longer to reset. Make
sure the charger vents are
not blocked. Wait and try
again.
On a severely discharged
battery, charge for 10 to 15
minutes in the 10 amp rate
to help assist in cranking.

•12 •
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
Charger will not turn on
when properly connected. AC outlet is dead.
Poor electrical connection.
Check for open fuse or
circuit breaker supplying AC
outlet.
Check power cord and
extension cord for loose
tting plug.
The battery is connected
and the charger is on, but
is not charging.
Clips are not making a
good connection. Check for poor connection at battery and frame. Make
sure connecting points are
clean. Rock clips back and
forth for a better connection.
The measured current is
much lower than what was
selected.
The charger reached the
maximum voltage and is
reducing the current.
No problem, this is a normal
condition.
BEFORE RETURNING FOR REPAIRS17.
When a charging problem arises, make certain that the battery is capable17.1
of accepting a normal charge. Use a good battery to double check all
connections, the AC outlet for a full 120-volts, the charger clips for correct
polarity and the quality of the connections from the cables to the clips and
from the clips to the battery system. The clips must be clean.
When a battery is very cold, partially charged or sulfated, it will not draw17.2
the full rated amperes from the charger. It is both dangerous and damag-
ing to a battery to force higher amperage into it than it can effectively use
in recharging.
When an UNKNOWN OPERATING PROBLEM arises, please read the17.3
complete manual and call the customer service number for information
that will usually eliminate the need for return.
If the above solutions do not eliminate the problem or for information about troubleshooting
or replacement parts, call toll-free from anywhere in the U.S.A.
