Mounting the Unit Using the Hanging Hook
The hanging hook allows you to position the battery charger for convenient, hands-free operation.
CAUTION: TO REDUCE THE RISK OF PRODUCT DAMAGE:
• When the charger is hung by the hanging hook or attached using the magnetic discs, do not shake the charger
or object that it is hanging from or attached to. Do not hang the charger from or attach the charger to any
electrical wires or anything that it is not secure.
• Only use the hanging hook or magnet discs for hanging or positioning the charger. The hanging hook and
magnetic discs are not intended to support additional weight. Do not attach or hang anything additional to the
charger or risk of breakage may occur.
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.
• Do not set a battery on top of charger.
• Never allow battery acid to drip on charger.
• Charge above freezing temperature and below 40°C (104°F).
• Never operate charger in a closed-in area or restrict ventilation in any way.
• Marine batteries must be removed and charged on shore.
Connection Precautions
• Never allow clamps or ring terminals to touch each other.
• Attach clamps to battery and chassis as indicated in the appropriate section (“Charging a battery installed in a
vehicle” or “Charging a battery that has been removed from a vehicle”).
Charging a battery 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.
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. Do not charge the battery while the engine is operating.
8. See operating instructions for length of charge information.

SETTING UP THE UNIT
Ensure that all installation and operating instructions and safety precautions are understood and carefully
followed by anyone installing or using the battery charger. Follow the steps outlined in the “Important Safety
Instructions” section of this manual.
Mounting the Unit Using the Magnetic Discs
The magnetic discs in the bottom of the unit allow you to position the battery charger on any flat,
secure metallic surface.
