3. Connect the AC power plug to the 120 VAC electrical service outlet. Then
follow the normal start up procedures for the Battery Tender Battery
Charger® High Frequency SMT Golf Car Charger.
WARNING
POSITIVE & NEGATIVE VEHICLE GROUND SYSTEMS:
1. If the positive (pos, p, +) battery post is connected to the vehicle chassis,
then the vehicle has a positive ground system. If the negative (neg, n, -)
battery post is connected to the vehicle chassis, then the vehicle has a
negative ground system. Negative ground systems are the most common.
2. For negative ground systems, connect the positive (red) alligator clip, or
ring terminal to the positive battery post. Then connect the negative
(black) alligator clip to the positive battery post. You may also connect the
negative (black) alligator clip to the vehicle chassis, but DO NOT make the
negative charger alligator clip connection to the carburetor, fuel lines, or
thin, sheet metal parts. Make that connection to the engine block or a
heavy gauge metal part of the frame.
3. For positive ground systems, connect the negative (black) alligator clip
to the negative battery post. Then connect the positive (red) alligator clip
to the positive battery post. If you prefer, you may also connect the
positive (red) alligator clip to the vehicle chassis, but DO NOT make the
positive (red) charger alligator clip connection to the carburetor, fuel lines,
or thin, sheet metal parts. Make that connection to the engine block or a
heavy gauge metal part of the frame. Then connect the positive (red)
alligator clip, or ring terminal to the vehicle chassis. Do not make the
positive charger clip or ring connection to the carburetor, fuel lines, or thin,
sheet metal parts. Make that connection to the engine block or a heavy
gauge metal part of the frame.

1. FOR USE ONLY IN THE UNITED STATES, THE USE OF A 3 TO 2
PRONG GROUND ADAPTER PLUG IS NOT ALLOWED IN CANADA.
Your battery charger is designed for use on a nominal 120-volt circuit. It
comes equipped with a grounding plug that looks like the one illustrated in
Figure 2A. A temporary adaptor (Figure 2C), may be used to connect this
plug to a two-pole receptacle as shown in Figure 2B if a properly grounded
outlet is not available. The temporary adapter should be used only until a
properly grounded outlet can be installed by a qualified electrician.
2. DANGER - Before using the adapter as illustrated, be certain that the
center screw of 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 that it is grounded. If necessary, replace original
outlet cover plate with a longer screw that will secure adapter ear or lug to
outlet cover plate and make ground connection to a grounded outlet.

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 have the following special features:
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.
