3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter
than NEGATIVE (NEG, N, –) post.
4. Determine which post of battery is grounded (connected) to the chassis. If negative post is
grounded to chassis (as in most vehicles), see 5. If positive post is grounded to the chassis,
see 6.
5. For negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE
(POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) clamp to vehicle chassis or
engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body
parts. Connect to heavy gauge metal part of the frame or engine block.
6. For positive-grounded vehicle, connect NEGATIVE (BLACK) clamp from battery charger to
NEGATIVE (NEG, N, –) ungrounded post of battery. Connect POSITIVE (RED) clamp 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.
7. When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then
remove clamp from battery terminal.
8. Do not charge the battery while the engine is operating.
9. See operating instructions for length of charge information.
Follow these steps when the battery has been removed from a vehicle
WARNING – A spark near the battery may cause an explosion. To reduce risk of a
spark near the battery:
1. Check polarity of battery posts. The Positive post (marked POS,P, +) usually has a larger
diameter than the Negative battery post (marked NEG, N, –).
2. Attach a 24-inch (minimum length) AWG #6 insulated battery cable to the Negative battery post
(marked NEG, N, –).
3. Connect the Positive (RED) battery clamp to the Positive battery post (marked POS, P, + or red).
4. Stand as far back from the battery as possible, and do not face battery when making final
connection.
5. Carefully connect the NEGATIVE (BLACK) charger clamp to the free end of the battery cable
connected to the negative terminal.
6. When disconnecting charger, always do so in reverse sequence of connecting procedure and
break first connection while as far away from battery as practical.
Note:
A marine (boat) battery must be removed and charged on shore. To charge it on board requires
equipment specifically designed for marine use. This unit is NOT designed for such use.
• Check unit periodically for wear and tear. Return to manufacturer for replacement of worn
or defective parts immediately.
• Read and Understand This Instruction Manual Before Using This Unit.
SAVE THESE INSTRUCTIONS
WARNING – TO REDUCE THE RISK OF INJURY:
Follow these instructions and those published by the battery manufacturer and manufacturer of any
equipment you intend to use with this unit. Review cautionary markings on this product and on
engine.
• Do not open the BATTERY CHARGER — there are no user-serviceable parts inside.
Opening the battery charger will void manufacturer’s warranty.
• Operate battery charger only as described in this Instruction Manual.
• Check battery charger and components periodically for wear and tear. Return to
manufacturer for replacement of worn or defective parts immediately.
PREPARING TO CHARGE
1. Be sure area around battery is well ventilated while battery is being charged.
2. Remove battery completely from boat/airplane or any confined area before charging.
3. If it is necessary to remove battery from vehicle to charge, or to clean terminals, always remove
grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not
to cause an arc.
4. Clean battery terminals, taking care to avoid getting corrosive material in eyes.
5. 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
(maintenance free), carefully follow manufacturer’s charging instructions.
6. Study all battery manufacturer’s specific precautions, such as removing or not removing cell caps
while charging, and recommended rates of charge.
7. Determine voltage of battery to be charged by referring to the vehicle manual. The unit is for
charging a 12 volt battery only.
Charger Location
• Locate charger as far away from battery as cables permit.
• Never place charger directly above battery being charged; gases from battery will corrode
and damage charger.
• Never allow battery acid to drip on charger when reading gravity or filling battery.
• Never operate charger in a closed-in area or restrict ventilation in any way.
• Marine batteries must be removed and charged on shore.
• Do not set a battery on top of charger.
Connection Precautions
• Connect and disconnect output clamps only after removing AC cord from electric outlet.
• Never allow clamps to touch each other.
• Attach clamps to battery and chassis as indicated in “Battery Installed in Vehicle” steps 5
and 6, or in “Battery Outside of Vehicle” steps 2 to 5.
Follow these steps when the battery is installed in a vehicle
WARNING – A spark near the battery may cause an explosion. To reduce risk of a
spark near the battery:
1. Position AC and clamp cords to reduce risk of damage by hood, door, or moving engine part.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
