5. Study all battery manufacturer’s specific precautions, such as removing or not
removing cell caps while charging, and recommended rates of charge.
6. Remove battery completely from boat/airplane or any confined area before charging.
Area around battery should be well ventilated while battery is being charged. Do not
operate while an enclosed area.
CAUTION: This battery charger does not detect, diagnose or analyze the condition of
the battery. Attempting to charge/maintain a battery with an abnormal condition can
further damage the battery. If in doubt, have the battery checked by a qualified
professional prior to using this unit.
IMPORTANT: Do not start the vehicle with the charger connected to the AC outlet, or
it could result in damage to the charger.
Charger Location
1. Locate battery charger as far away from battery as cables permit.
2. Charge above freezing temperature and below40 degree Celsius(C) (104 degree
Fahrenheit).
3. NEVER place battery charger directly above battery being charged; gases from
battery will corrode and damage charger.
4. NEVER allow battery acid to drip on battery charger when reading gravity or filling
battery.
5. NEVER operate battery charger in a closed-in area or restrict ventilation in anyway.
6. Marine batteries must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use. This unit is NOT designed for
such use.
7. Do not set a battery on top of battery charger.
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE AN EXPLOSION. TO
REDUCE RISK OF A SPARK NEAR THE BATTERY: CONNECT AND DISCONNECT
DC OUTPUT CLAMPS AND RING TERMINALS ONLY AFTER REMOVING AC CORD
FROM ELECTRIC OUTPUT.
Connection Precautious
1. Disconnect AC cord from electric outlet before connecting or disconnecting DC clamps.
Follow these steps when the battery is installed in a vehicle:
1. Position AC and clamp cords away from hood, door, or moving engine parts.
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, +) engine block away from 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 a 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
