Operating instructions
Preparing to charge
1. Determine voltage of battery to be charged by referring to
the vehicle manual.
2. Remove battery completely from car/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.
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.
•
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.
Charging using the supplied battery clips
WARNING: a spark near the battery may cause an
explosion. To reduce the risk of a spark near the battery
position AC and DC cords away from hood, door, or
moving engine parts.
1. Set the battery voltage selector to the correct voltage.
2. Insert the double barrel tip of the battery clip cable into
the battery charger.
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. After the battery has been connected to the charger, plug
the 240V AC plug into the socket and turn on. The power
LED will light red to indicate that the charger is plugged
in and ready. DO NOT TURN ON THE 240V AC until the
battery has been connected.
Note: If the clamps are incorrectly connected with regard
to polarity, the reverse polarity LED will light. Unplug the
charger; then remove the clamps. Reconnect the clamps
properly.
