When charging battery in the vehicle, take care to determine the battery type and which post is grounded (connected to vehicle chas-

sis). To reduce risk of a spark near battery, follow these steps when battery is installed in vehicle.

When charging battery out of vehicle, take care to determine the battery type. To reduce risk of a spark near battery, follow these steps

when battery is outside vehicle. 

WARNING: A spark near the battery may cause battery explosion. WARNING: When removing battery

from vehicle or boat, disconnect grounded pole first. When disconnecting, make sure all accessories are off, so as not to cause an arc.

(

NOTE: A marine (boat) battery must be removed and charged on shore. (To charge on board requires special equipment designed for

marine use.)

WARNING: When reinstalling battery, attach the ground post first.

1.  Position AC power cord and DC charging 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.

3.  Check polarity of battery posts. Battery case will be marked

by each post: 

N, -). NOTE: The positive battery post usually has a larger 

diameter than the negative post.

4.  Determine  which  post  of  battery  is  ground  (connected)  to

chassis. 

  NOTE: The negative post is normally grounded.

5A.    For negative-grounded vehicle, connect POSITIVE (RED)

clip from battery charger to POSITIVE (POS, P, +) ungrounded

post  of  battery.  Connect  NEGATIVE  (BLACK)  clip  to  vehicle

chassis or engine block away from battery. Connect to a heavy

gauge metal part of the frame or engine block.

5B.    For positive-grounded vehicle, connect NEGATIVE (BLACK)

clip from battery charger to NEGATIVE (NEG, N, -) ungrounded

post of battery. Connect POSITIVE (RED) clip to vehicle chassis

or engine block away from battery. Connect to a heavy gauge

unpainted metal part of the frame or engine block.

WARNING: Do not connect clip to carburetor, fuel lines, or sheet-

metal body parts.

NOTE: Attach clips to battery post and twist 

or rock back and forth several times to make a good connection.

This tends to keep clips from slipping off terminals and helps to

reduce risk of sparking.

6.  Select amperage.

7.  Follow steps 1-4 in Battery Charger Section K.

8.  When the battery is fully charged, unplug the charger from

the AC power source.

9.  Remove charger clips from (1) chassis and (2) battery pole

in that order.

10.  Clean and store battery charger.

1.  Check polarity of battery posts. Battery case will be marked

by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG,

N, -).

NOTE: The positive battery post usually has a larger 

diameter than the negative post.

2.  Attach a 24-inch long (or longer) 6-gauge (AWG) insulated

battery cable to NEGATIVE (NEG, N, -) battery post.

(The 24" lead is not supplied. You may purchase at most

automotive stores.)

The 24" lead provides a safer connection condition. Sparking

or arcing could occur when connecting the charger clip to 

the lead.

3.  Connect POSITIVE (RED) charger clip to POSITIVE (POS,

P, +) post of battery. Rock clip back and forth to make good

connection.

4.  Position yourself and free end of 24 inch cable as far away 

from battery as possible. Then connect NEGATIVE (BLACK)

charger clip to free end of cable. 

WARNING:    Do  not  face  battery  when  making  final

connection.  Rock  clip  back  and  forth  to  make  a  good

connection.

5.  Select amperage:

6.  Follow steps 1-4 in Battery Charger Section.

7.  When  battery  is  fully  charged,  unplug  charger  from  AC

outlet.

8.  When  battery  is  fully  charged  and  the  charger  is 

unplugged:

   (1)  Remove  clip  from  end  of  the  Negative  end  of  cable,

then 

(2) Remove clip from Positive battery post, in that order.

9.  Clean and store battery charger.

 

WARNING: Be sure area around the battery is well ventilated 

while battery is being charged. Gas can be forcefully blown 

away by using a piece of cardboard or other non-metallic

material as a fan.
