GENERAL PRECAUTIONS

WARNING

Battery posts, terminals and related accessories contain lead and lead
components, chemicals known to the State of California to cau se cancer
and birth defects or other reproductive harm. Always wash your hands
after handling these devices.

WARNING

Do not operate the battery charger with damaged AC power cords or
plugs or DC output cords or accessories – Replace damaged AC & DC
cords or accessories before using the charger. Replacement items can
be purchased from authorized Deltran charger product dealers.

CAUTION

WORKING WITH LEAD ACID BATTERIES AND BATTERY CHARGERS:

All lead acid batteries have the potential to emit gasses that may combine into
a combustible or explosive mixture. In many cases, it is possible that lead acid
batteries will emit these gasses during normal discharge and charging
operations. Because of this potential danger, it is important that you follow the
precautions recommended by both the battery and battery charger
manufacturers before using either one.
USING MANUALS: Study all of the battery manufacturer's precautions and
specific recommendations for safe operation such as not removing cell caps
while charging and the recommended rates of charge (charger output current).

CAUTION

CHARGER VOLTAGE COMPATIBILITY: NEVER use a battery charger

unless the battery voltage matches the output voltage rating of the charger.
For example, do not use a 12-volt charger with a 6-volt battery and vice-versa.
CHARGER LOCATION: LOCATE the charger as far away from the battery as
is allowed by the length of the output cable harness. NEVER set the charger
above the battery. NEVER set the charger on a surface constructed from
combustible material. NEVER place the battery, the charger, or any of the
electrical connections between them in an area that is likely to become wet.
EXCESSIVE MOISTURE: Do not expose the battery charger or any of its
electrical connections (either AC or DC) to rain, snow, or extremely high,
condensing humidity.
CHARGER ATTACHMENTS: Do not use attachments that are not
recommended or sold by the charger manufacturer. To do otherwise may
result in the risk of electric shock, fire, or possibly some other unforeseen
potential personal injury situations.
HANDLING POWER CORDS: When handling electric power cords, always
pull by the plug rather than by the cord. This will reduce the risk of damage to
both the plug and cord, and it will minimize the likelihood of electric shock
resulting from that damage.
LOCATION OF POWER CORDS: Make sure all electric power cords are
located so that they cannot be stepped on, tripped over, or otherwise
subjected to damage or stress.
MONITORING SEALED & NON-SEALED BATTERIES: When leaving a
battery charger connected to either a sealed (AGM or GEL) or non-sealed
(flooded battery) for extended periods of time (weeks, months, etc.),
periodically check the battery to see if it is unusually warm. This is an
indication that the battery may have a weak cell and that it could go into a
thermal runaway condition. If the battery releases an excessive amount of gas
or if the battery gets hotter than 130°F (55°C) during charging, disconnect the
charger and allow the battery to cool. Overheating may result in plate
distortion, internal shorting, drying out or other damage. For flooded batteries,
also check individual cell fluid levels against manufacturer's recommendations
for safe operation.

WARNING

ELECTRIC SPARK & OPEN FLAME: NEVER smoke or allow a source of

1

2

electric spark or open flame in the vicinity of the battery or engine. (For
example: Don't charge the battery next to a gas water heater.)
VENTILATION: Do not operate the charger where ventilation is restricted.
The intent here is to allow sufficient airflow to minimize and dissipate the heat
generated by the charger and to diffuse the gasses that may be emitted by the
battery.
CHARGER MAINTENANCE: NEVER disassemble the charger or attempt to
do internal repairs. Take it to a qualified service technician. Assembling the
charger incorrectly may result in the risk of electric shock or create a fire
hazard.

WARNING

EXTENSION CORDS: An extension cord should not be used unless

absolutely necessary. Using improper extension cord could result in a risk of
fire and electric shock. If extension cord must be used, make sure that:
¾ The pins on the extension cord plug have the same number, size, and

shape as those of the AC power cord plug on the charger;

¾ The extension cord is properly wired and is in good electrical condition; &
¾ The wire size is as specified in Table 1 below.

PERSONAL PRECAUTIONS

WARNING

WHEN YOU WORK NEAR LEAD-ACID BATTERIES:

1. Someone should be within range of your voice or close enough to come to
your aid if you have an accident;

2. Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes;

3. Wear complete eye protection and protective clothing. Avoid touching your
eyes while working near a battery. If battery acid contacts your skin or
clothing, wash immediately with soap and water. If acid enters an eye,
immediately flood the eye with running cold water for at least 10 minutes
and get medical attention as soon as possible;

4. Be extra cautious when handling metal tools around a battery. If you drop
a metal tool near a battery it might spark or create a short circuit between
the battery terminals and some other metal part. Either event may cause
a dangerous electrical shock hazard, a fire, or even an explosion;

3

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-circuited current high enough to weld a metal ring or other
piece of jewelry, causing a severe burn;

6. Use

INFORMATION NOTE ABOUT DRY-CELL BATTERIES:

There are some wet, non-spillable, lead acid batteries on the market whose
manufacturers' make the claim that they are dry-cell batteries. These batterie s
are sealed, gas-recombinant, starved electrolyte, possibly with AGM

(Absorbed Glass Mat) type construction. It is perfectly safe to use

Battery

Tender Battery Charger® High Frequency SMT Golf Car C hargers

charge these types of batteries. The dry-cell battery warning is intended for

to

non-rechargeable, alkaline and other similar types of batteries. If you have any
doubt about the type of battery that you have, please contact the battery
manufacturer before attempting to charge the battery.

7. NEVER charge a visibly damaged or frozen battery.

PREPARING TO CHARGE: First, follow all General &

Personal Precautions as previously explained, and then
continue.

WARNING

IF THE BATTERY MUST BE REMOVED FROM THE VEHICLE:

1. To avoid an electric arc (or spark), turn off or disconnect all of the
accessories in the vehicle. Then always remove the cable that is
connected to grounded terminal from battery first;

2. If necessary, clean the battery terminals. Be careful to keep the corrosion
and other debris from coming in contact with your eyes;

3. If the battery is not a sealed battery, then if necessary, add distilled water
to each cell until the battery acid solution reaches the level specified by
battery manufacturer. Do not overfill;

4. Check the polarity of the battery posts.

5. Connect the AC power plug to the 120 VAC electrical service outlet. Then
follow the normal start up procedures for the

Charger® High Frequency SMT Golf Car Charger.

WARNING

IF THE BATTERY REMAINS INSTALLED IN THE VEHICLE:

1. Place both the AC and DC power cords in the best position to avoid
accidental damage by movable vehicle parts, i.e. hoods, doors, or moving
engine parts (fan blades, belts, or pulleys).

2. Check the polarity of the battery posts. If the positive (pos, p, +) post is
connected to the vehicle chassis, then the vehicle has a positive ground
system. If the negative (neg, n, -) post is connected to the vehicle chassis,
then the vehicle has a negative ground system. Negative ground systems
are the most common.

ADDITIONAL CHARGER INFORMATION

AUTOMATIC CHARGING AND BATTERY STATUS
MONITORING: Battery Tender Battery Charger® High Frequency SMT

Golf Car Chargers are completely automatic and may be left connected to both
AC power and to the battery that it is charging for long periods of time.
However, it is prudent to periodically check both the battery and the charger for
normal operation during these extended charging periods.

Battery Tender Battery Charger® High Frequency SMT Golf Car Chargers
have status lights that indicate the operating mode of the charger, and the
condition of the battery that is connected to the charger. The charger output
power, voltage, and current all depend on the charge algorithm and the
condition of the battery that is being charged. The continuity of the AC power
that is connected to the charger is also a significant factor.

WARNING

BATTERY CONNECTION OR AC POWER INTERRUPTED:

1. If the battery connection to either charger output channel is interrupted, the
yellow & Green LED’s turn off and the Red LED begins to flash.

2. If the AC power to the charger is interrupted, the yellow & Green LED’s
turn off and the Red LED begins to flash, and the charger program is
reset.

The charger operates in one of the 4 primary charge modes: the BULK mode
(full charge power, constant current, increasing battery voltage, battery is 0%
to 75% or 80% charged), the ABSORPTION mode (high constant voltage,
decreasing current, battery is 75% to 100% charged), the EQUALIZATION
mode (higher constant voltage, with lower current limit), or the STORAGE /
FLOAT MAINTENANCE mode (low constant voltage, minimal charge current ,
battery is fully charged, typically 100% to 103%).

SPECIAL FEATURES: Battery Tender Battery Charger® High

Frequency SMT Golf Car Chargers

SPARKPROOF: The battery charger positive and negative DC output

leads must be connected to a battery before any output voltage is developed.

SHORT CIRCUIT PROTECTION: The battery charger can sustain a

short circuit connection directly across its DC output terminals indefinitely
without any risk of either electric shock or excessive heat.

REVERSE POLARITY PROTECTION: The battery charger is

protected internally against any damage due to the DC output leads being
connected to the opposite polarity battery post. No damage will result to either
the battery or the battery charger.

TIME REQUIRED TO CHARGE A BATTERY: Battery Tender Battery

Charger® High Frequency SMT Golf Car Chargers will charge at different
maximum rates depending upon the nominal output voltage. 12V & 24V
models charge at a maximum rate of 20 Amps. 36V models charge at 15
Amps and 48V models charge at 10 Amps. The time required to charge a
battery depends on both the Amp-Hour capacity rating of the battery and the
output current of the charger.

10 Amps 8.0 Hours 22.0 Hours 16.0 Hours 42.0 Hours

WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY
LOW VOLTAGE: If a 12 Volt, Lead-Acid battery has an output voltage of

less than 9 volts when it is at rest, when it is neither being charged nor
supplying electrical current to an external load, there is a good chance that the
battery is defective. As a frame of reference, a fully charged 12-Volt, Lead­Acid battery will have a rest-state, no-load voltage of approximately 12.9 volts.
A fully discharged 12-Volt, Lead-Acid battery will have a rest-state, no-load
voltage of approximately 11.4 volts. That means that a voltage change of only

1.5 volts represents the full range of charge 0% to 100% on a 12-Volt, Lead­Acid battery. Depending on the manufacturer, and the age of the battery, the
specific voltages will vary by a few tenths of a volt, but the 1.5-volt range will
still be a good indicator of the battery charge %.

STATUS INDICATOR LIGHT OPERATION:

INITIALIZATION: WHEN YOU FIRST TURN ON THE AC POWER: All 3
Indicator Lights will Turn On in sequence: Green, then Green & Amber
together, then Green, Amber & Red together for approx 1 second each. Also,
a Safety Monitor Circuit verifies appropriate battery voltage levels and good
electrical continuity between the battery and the charger DC output. Then the
normal battery charging program sequence will begin.

NORMAL INDICATOR LIGHT OPERATING SEQ UENCE: 1) Amber Constant

2) Amber Constant and Green Flashing 3) Green Constant.

¾ AMBER (Yellow) Flashing - When the amber light is flashing, the AC

power is applied to the charger and the microprocessor circuitry is
functioning properly. There is no battery connected or there is a problem
with the connections between the charger and the battery.

¾ AMBER (Yellow) - When the amber light is on, the charger is functioning

normally and it is the process of fully charging the battery. The charger
will automatically apply the optimum charging voltage and current values
to the battery in the proper timing sequence.

¾ GREEN Flashing - When the green light is flashing (and the Amber light

is still on), the battery charger is in the absorption mode of operation. In
this mode the charger maintains constant voltage & charge current
decreases to maintenance levels.

¾ GREEN - When the green light is on (and no other lights are on), the

battery is fully charged in the maintenance mode or nearly fully charged in
the equalization mode. Either way, the battery may be used at this time.

¾

RED Flashing - When the red light is flashing, more than 50 hours has
elapsed from the time that the charger AC power was turned and battery
condition still does not allow the initiation of absorption charge.

APPLICATION / TROUBLESHOOTING INFORMATION:

¾ Always operate the charger in a well ventilated area.
¾ If no indicator lights come on after you plug in the AC cord, then check

the AC power receptacle.

¾ If the AC power is disconnected, the LED indication maybe delayed

several seconds up to 1 minute due to AC filter cap storage state. After
the AC power comes back on, the charger program will reset.

¾ If the green indicator light comes on in less than 2 minutes, check the

battery and the output connections from the charger.

¾ It will take a long time (possibly more than 24 hours, or even 96 hours)

for the green light to come on when charging a large battery or a very
large battery bank. The theoretical maximum time to steady green light
= 127 hours. That would occur when charging a 500 Amp Hour
battery bank with a 10 amp charger.

¾ If the DC charger output connection to the battery is broken while the

charger is operating normally with AC power applied, the Amber light
will begin to flash, and the charger output voltage will be shut off. If
the DC connection to the battery is restored, then the charger program
will reset.

BATTERY CONNECTIONS TO THE CHARGER:

In each case the nominal battery pack voltage must match the charger voltage.
Always exercise caution when connecting the charger to the battery pack.

In the first example, a 36 volt charger is connected to a 36 volt battery pack. One
pack consists of 6 separate 6 volt batteries all connected in series. The other pack
consists of 3 separate 12 volt batteries, all connected in series.

This second example shows a 48 volt charger connected to a 48 volt battery pack.
Three packs are shown: 8 separate 6 volt batteries in series, 4 separate 12 volt
batteries in series, and 6 separate 8 volt batteries in series.

The next example shows a 24

8

volt charger connected to a 24
volt battery pack.

Three packs are shown: 4 separate 6 volt batteries in series, 2 separate 12 volt

batteries in series, and 3 separate 8 volt batteries in series.

Each of the battery packs shown so
far have only had batteries
connected in series. Notice how
the positive post (terminal) of one
battery is connected to the
negative post (terminal) of the next
battery. The voltage of each
battery adds to create a larger total
battery pack voltage.

PARALLEL CONNECTIONS: When batteries are connected in parallel,

the positive posts are connected together, and the negative posts are connected
together. The result is that the battery voltage stays the same, but the total output
capacity (amp-hours) of the battery pack is increased for each additional battery

that is connected in parallel.

Many combinations are possible. The 3 examples of batteries connected in parallel
above show two 12-volt batteries, three 8-volt batteries, and four 6-volt batteries.
Notice that each example shows the total battery pack voltage to be exactly the
same as each individual battery. Also, the total battery pack amp-hour capacity is
increased equally by the total number of batteries. 2 x 85 Ah = 170 Ah. 3 x 60 Ah =
180 Ah. 4 x 75 Ah = 300 Ah.
