c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d. Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery without
cell caps, carefully follow manufacturer's recharging instructions.
e. Study all battery manufacturers’ specific precautions such as removing or not removing cell
caps while charging and recommended rates of charge.
f. Determinate 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.
7. CHARGER LOCATION
a. Locate charger as far away from battery as the DC cable permits.
b. Never place charger directly above battery being charged; gases from battery will corrode and
damage charger.
c. Never allow battery acid to drip on charger when reading gravity or filling battery.
d. Do not operate charger in a closed-in area or restrict ventilation in any way.
e. Do not set a battery on top of charger.
8. DC CONNECTION PRECAUTIONS
a. Connect and disconnect DC output clips only after removing AC cord from electric outlet.
Never allow clips to touch each other.
b. Attach clips to battery and chassis
Follow these steps when battery is installed in vehicle. A spark near battery may cause battery
explosion. To reduce risk of a spark near battery:
a. Position AC and DC cords to reduce the risk of damage by hood, door, or moving engine
parts.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger
diameter than NEGATIVE (NEG, N, -) post.
d. Determine which battery post is grounded {connected) to the chassis. If negative post is
grounded to chassis (as in most vehicles), see (e). If the positive post is grounded to the chassis.
e. 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 the carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine
block.
f. For positive-grounded vehicle, only 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 the carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine
block.
h. See operating instructions for length of charge information.
Follow these steps when battery is outside vehicle. A spark near battery may cause battery
explosion. To reduce risk of a spark near battery:
a. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger
