capacities of 24Ah (6V) and 44-75Ah (12V).
It is not intended to supply power to a low
voltage electrical system other than in a
starter-motor application. Do not use battery
charger for charging dry-cell batteries that
are commonly used with home appliances.
These batteries may burst and cause injury
to persons and damage to property.
WARNING:
Do not use this charger for
charging Lithium Ion batteries other than
the Lithium Iron Phosphate (LiFePO
4
)
type. Other Lithium Ion battery types
may not be sufficiently charged or
may be overcharged with this charger.
Overcharging may ignite or burst a battery
and cause injury to persons and damage
to property.
NOTE:
12V LiFePO
4
batteries can only be
charged; the
Recovery setting (“REC”)
does not apply for this battery type. If the
“LITH” battery type is chosen, the rate of
charge automatically defaults to 12V, the
only rate allowed. For Battery Type and
Battery Voltage settings, see Section 11.
3.9
NEVER charge a frozen battery.
4. PREPARING TO CHARGE
4.1
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.
4.2
Be sure area around battery is well
ventilated while battery is being charged.
4.3
Clean battery terminals. Be careful to
keep corrosion from coming in contact
with eyes.
4.4
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.
4.5
Study all battery manufacturer’s
specific precautions while charging and
recommended rates of charge.
4.6
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.
5. CHARGER LOCATION
5.1
Locate charger as far away from battery
as DC cables permit.
5.2
Never place charger directly above
battery being charged; gases from battery
will corrode and damage charger.
5.3
Never allow battery acid to drip on
charger when reading electrolyte specific
gravity or filling battery.
5.4
Do not operate charger in a closed-in
area or restrict ventilation in any way.
5.5
Do not set a battery on top of charger.
6. DC CONNECTION PRECAUTIONS
6.1
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.
6.2
Attach clips to battery and chassis, as
indicated in sections 7 and 8.
7. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE
WARNING: A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE RISK OF
A SPARK NEAR THE BATTERY:
7.1
Position AC and DC cords to reduce risk
of damage by hood, door, or moving
engine part.
7.2
Stay clear of fan blades, belts, pulleys, and
other parts that can cause injury to persons.
7.3
Check polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has larger
diameter than NEGATIVE (NEG, N, –) post.
7.4
Determine which post of the battery is
grounded (connected) to the chassis.
The battery terminal not connected to the
chassis has to be connected first. The other
connection is to be made to the chassis,
remote from the battery and fuel line. The
battery charger is then to be connected to
the supply mains. See steps 7.5 and 7.6.
7.5
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
