NOTE: During charging, the display will

go into sleep mode and will not show the

percentage of charge or voltage of the

battery. To turn the display back on, press

any button.

• Battery % – The digital display shows

an estimated charge percentage of

the battery connected to the charger’s

battery clamps.

• Voltage – The digital display shows the

voltage at the charger battery clamps, in

DC volts.

CHARGING RATE BUTTON

Use this button to select one of the

following:

• 3A – For charging small batteries, such as

those commonly used in garden tractors,

snowmobiles and motorcycles. Also used

to maintain fully charged large batteries.

• 12A or 15A – For charging automotive,

marine and light truck batteries. Not

intended for industrial applications.

BATTERY TYPE BUTTON

Use this button to select the type of battery.

•

– Used in cars, trucks and

motorcycles, these batteries have

vent caps and are often marked “low

maintenance” or “maintenance-free”.

This type of battery is designed to

deliver quick bursts of energy (such as

starting engines) and has a greater plate

count. The plates are thinner and have

somewhat different material composition.

Regular batteries should not be used for

deep-cycle applications.

•

– The Absorbed Glass Mat

construction allows the electrolyte to be

suspended in close proximity with the

plate’s active material. In theory, this

enhances both the discharge and recharge

efciency. The AGM batteries are a variant

of Sealed VRLA (valve regulated lead-acid)

batteries. Popular uses include high-

performance engine starting, power sports,

deep-cycle, solar and storage batteries.

Model SSC-1500A-CA only:

– The electrolyte in a GEL cell has

a silica additive that causes it to set up or

stiffen. The recharge voltages on this type of

cell are lower than those for other styles of

lead-acid battery. This is probably the most

sensitive cell in terms of adverse reactions

to overvoltage charging. Gel batteries are

best used in VERY DEEP cycle application

and may last a bit longer in hot weather

applications. If the wrong battery charger is

used on a gel cell battery, poor performance

and premature failure will result.

11. OPERATING INSTRUCTIONS

WARNING: A spark near battery may

cause a battery explosion.

IMPORTANT: Do not start the vehicle with

the charger connected to the AC outlet, or

it could result in damage to the charger.

NOTE: This charger is equipped with

an auto-start feature. Current will not be

supplied to the battery clamps until a

battery is properly connected. The clamps

will not spark if touched together.

CHARGING A BATTERY

IN THE VEHICLE

1. Turn off all the vehicle’s accessories.

2. Keep the hood open.

3. Clean the battery terminals.

4. Place the charger on a dry, non-

ammable surface.

5. Lay the AC/DC cables away from any

fan blades, belts, pulleys and other

moving parts.

6. Connect the battery, following the

precautions listed in sections 6 and 7.

7. Connect the charger to an electrical

outlet.

8. Select the battery type and charging

rate.

9. When charging is complete,

disconnect the charger from the AC

power, remove the clamps from the

vehicle’s chassis, and then remove

the clamp from the battery terminal.

CHARGING A BATTERY

OUTSIDE OF THE VEHICLE

1. Place battery in a well-ventilated area.

2. Clean the battery terminals.

3. Connect the battery, following the

precautions listed in sections 6 and 7.

4. Connect the charger to the electrical

outlet.

5. Select the battery type and

charging rate.

6. When charging is complete,

disconnect the charger from the AC

power, disconnect the negative clamp,

and nally the positive clamp.

7. A marine (boat) battery must be

removed and charged on shore.
