CHARGING A BATTERY INSTALLED IN A VEHICLE
Follow these steps when the battery is installed in a vehicle. A spark near a battery may
cause battery explosion. For safety and to reduce the risk of spark near the battery:
1. Position AC and DC cords to reduce risk of damage by hood, door or moving
engine parts.
2. Stay clear of fan blades, belts, pulleys and other parts that can cause injury to
persons.
3. Check the polarity of the battery posts. A Positive (Pos, P, +) battery post
usually has a larger diameter than a Negative (Neg, N, -) post.
4. Determine which post of the battery is grounded (connected) to the chassis (en-
gine block). If the Negative post is grounded to the Engine Block (as in most
vehicles), see sub paragraph 5. If the Positive post is grounded, see sub paragraph
6.
5. For a Negative grounded vehicle, connect the Positive (Red) DC cable from the
charger to the Positive of the battery post. Connect the Negative (Black) DC cable
from the charger to a section of heavy gauge metal part of the frame or engine block
which is away from battery. Do not connect to carburetor, fuel lines or sheet metal
body parts.
6. For a Positive grounded vehicle, connect the Negative (Black) DC cable from the
charger to the Negative of the battery post. Connect the Positive (Red) DC cable
from the charger to a section of heavy gauge metal part of the frame or engine block
which is away from battery. Do not connect to carburetor, fuel lines or sheet metal
body parts.
7. Connect the charger AC power cord to the AC outlet.
8. When disconnecting the charger, turn switches to off, disconnect AC power cord,
remove connection from the vehicle chassis and then remove connection from the
battery terminal.
CHARGING A BATTERY OUTSIDE THE VEHICLE
Follow these steps when the battery is outside the vehicle. A spark near the battery may
cause battery explosion. For safety and to reduce risk of spark near the battery, connect the
charger as follows:
1. Check the polarity of the battery posts. A Positive (Pos, P, +) battery post
usually has a larger diameter than a Negative (Neg, N, -) post.
2. Attach a piece of at least 3" of AWG # 4 insulated battery cable to the Negative
battery post.
3. Connect the Positive (Red) DC cable from the charger to the Positive battery post
4. Position yourself and the free end of the piece of cable attached to the Negative
post as far away from the battery as possible and then connect the Negative
(Black) DC cable from the charger to the free end of the piece of cable attached to
the Negative battery post.
5. Do not face the battery when making the final connection.
6. Connect the charger AC power cord to the AC outlet.
7. When disconnecting the charger, always do so in reverse sequence of connecting
procedure and break the first connection while standing as far away from the
battery as practical.
