3.1  If necessary to remove battery from 

vehicle to charge, always remove 

grounded terminal from battery first. Make 

sure all accessories in the vehicle are off, 

so as not to cause an arc.

3.2  Be sure area around battery is well 

ventilated while battery is being charged.

3.3  Clean battery terminals. Be careful to 

keep corrosion from coming in contact 

with eyes.

3.4  Add distilled water in each cell until 

battery acid reaches level specified by 

battery manufacturer. Do not overfill. For a 

battery without removable cell caps, such 

as valve regulated lead acid batteries, 

carefully follow manufacturer’s recharging 

instructions.

3.5  Study all battery manufacturer’s 

specific precautions while charging and 

recommended rates of charge.

3.6  Determine voltage of battery by referring 

to car owner’s manual and make sure that 

output voltage selector switch is set at 

correct voltage. If charger has adjustable 

charge rate, charge battery initially at 

lowest rate.

4.1  Locate charger as far away from battery 

as DC cables permit.

4.2  Never place charger directly above 

battery being charged; gases from battery 

will corrode and damage charger.

4.3  Never allow battery acid to drip on 

charger when reading electrolyte specific 

gravity or filling battery.

4.4  Do not operate charger in a closed-in 

area or restrict ventilation in any way.

4.5  Do not set a battery on top of charger. 

 

 

 

5.1  Connect and disconnect DC output clips 

only after setting any charger switches to 

“off” position and removing AC cord from 

electric outlet. Never allow clips to touch 

each other.

5.2  Attach clips to battery and chassis, as 

indicated in sections 6 and 7. 

 

6.1  Position AC and DC cords to reduce risk 

of damage by hood, door, or moving 

engine part.

6.2  Stay clear of fan blades, belts, pulleys, and 

other parts that can cause injury to persons.

6.3  Check polarity of battery posts. POSITIVE 

(POS, P, +) battery post usually has larger 

diameter than NEGATIVE (NEG, N,–) post.

6.4  Determine which post of battery is 

grounded (connected) to the chassis. If 

negative post is grounded to chassis (as 

in most vehicles), see (6.5). If positive 

post is grounded to the chassis, see (6.6).

6.5  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. Do not connect clip to 

carburetor, fuel lines, or sheet-metal body 

parts. Connect to a heavy gauge metal 

part of the frame or engine block.

6.6  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. Do 

not connect clip to carburetor, fuel lines, 

or sheet-metal body parts. Connect to a 

heavy gauge metal part of the frame or 

engine block.

6.7  When disconnecting charger, turn 

switches to off, disconnect AC cord, 

remove clip from vehicle chassis, and 

then remove clip from battery terminal.

6.8  See Operating Instructions for length of 

charge information.
