e.
For a positive-grounded vehicle, connect the negative (black)
clip from battery charger to negative (neg, n, -) ungrounded
post of battery'. Connect the positive (red) clip to the vehicle
chassis or engine block away from battery. Do not connect
clip to carburetor, fuel lines, or sheet-metal parts. Connect to
a heavy gauge metal part of the frame or engine block;
f.
Connect charger AC supply cord to an electric outlet;
g.
When disconnecting the charger, turn switches to off,
disconnect AC cord, remove clip from vehicle chassis, and
then remove clip from battery terminal.
10. Follow these steps when battery is outside the vehicle. A spark near the
battery may cause a battery explosion. To reduce risk of a spark near battery:
a.
Check polarity of battery posts. A positive (pos, p, +) battery
post may have a larger diameter than a negative (neg, n, -)
post;
b.
Attach at least a 24 inch long 6-gauge (AWG) insulated
battery cable to the negative (neg, n, -) battery post;
c.
Connect the positive (red) charger clip to the positive (pos, p,
+) post of battery;
d.
Position yourself and the free end of cable as far away from
battery as possible, then connect negative (black) charger clip
to free end of cable;
e.
Do not face battery when making final connection;
f.
Connect charger AC supply cord to an electric outlet;
g.
When disconnecting the charger, always do so in reverse
sequence of connecting procedure and break first connection
while standing as far away from the battery as is practical.
USER INSTRUCTIONS
AUTOMATIC CHARGING AND BATTERY STATUS MONITORING:
All
BATTERY TENDER® 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. The charger output power, voltage, and current depends on
the condition of the battery it is charging. BATTERY TENDER
®
chargers have
2 status indicator lights that provide a visual means to determine the operating
mode of the charger and hence the condition of the battery connected to the
charger.
The two-colored status indicator lights are available to determine whether the
charger is operating in one of the 3 primary charge modes: the bulk mode (full
charge, constant current, battery is 0% to 85% charged), the absorption mode
(high constant voltage, battery is 85% to 100% charged), or the storage/float
maintenance mode (low constant voltage, battery is 100% to 103% charged).
When the battery is fully charged, the green status indicator light will turn on
and the charger will switch to a storage/maintenance charge mode. The
BATTERY TENDER
®
charger will automatically monitor and maintain the
battery at full charge.

ELECTRICAL CONNECTIONS BETWEEN THE CHARGER AND THE
BATTERY:
Before charging, connect the alligator clips or ring terminals to the
battery terminals. Then connect the charger AC power cord to the AC power outlet.
When you want to disconnect the charger from the battery, first disconnect the charger
AC power cord from the AC power outlet. Then disconnect the charger leads from the
battery terminals.
WARNING
Always unplug or turn OFF the battery charger before connecting or
disconnecting the charger clamps to the battery. Connecting or disconnecting
clamps with the charger on could cause a spark resulting in a battery explosion.
A battery explosion may rupture the battery case causing a discharge or spray of
sulfuric acid which could result in serious injury or death.
CONNECTIONS FOR ALL LEAD-ACID BATTERY TYPE:
(See
item 10 under
General Precautions.)
In General: First connect the red positive (+) charger output lead to the
positive terminal of the battery. Then connect the black negative (-) charger
output lead to the negative terminal of the battery. However, pay particular
attention to the next two items and the instructions under item 18 under
General Precautions.
As an added measure of safety, particularly when working with standard,
flooded, lead acid batteries, UL recommends that the second, negative (-)
charger output lead connection be made to the grounded equipment chassis
rather than directly to the negative battery post.
In similar fashion, for positive ground systems, the positive post of the battery
is now at the same electrical potential as the grounded equipment chassis.
Therefore UL recommends that the positive (+) charger output lead
connection be made at the grounded equipment chassis rather than directly
to the positive battery post.
ATTENTION: BATTERY TENDER
®
CHARGERS HAVE A SPARK FREE
CIRCUITRY.
The output alligator clips or ring terminals will not spark when they are
touched together. The BATTERY TENDER
®
chargers will not produce an output
voltage until it senses at least 3 volts from the battery. It must be connected to a battery
with the correct polarity before it will start charging a battery. Therefore, if you plug the
AC power cord into an AC power outlet, and if the output alligator clips or ring terminals
are not connected to a battery, and if you touch the alligator clips or ring terminals
together, there will be no electrical spark.
NOTE:
THE OUTPUT CLIPS OR RING TERMINALS MUST BE CONNECTED TO A
BATTERY BEFORE THE CHARGER CAN PRODUCE AN OUTPUT VOLTAGE.
If the charger is hooked up backwards, the amber light will continue flashing
(International Plus and EURO400), indicating that a charge has not been initiated
(WP800 does not show any light at all). The alligator clips or accessory ring terminals
must be connected to the battery, with the proper polarity, Red to Positive (+ output to
+ battery post) and Black to Negative (- output to - battery post), before the charger will
generate any output voltage.
