Preparing to Charge
WARNING: Use this charger only on flooded lead-acid batteries. Other batteries may be damaged or may
overheat, leak, or catch fire.
WARNING: A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK
NEAR BATTERY FOLLOW THESE INSTRUCTIONS EXACTLY.
TO PREVENT SERIOUS INJURY:
Wear ANSI-approved splash-resistant safety goggles and heavy-duty rubber work gloves
whenever connecting, disconnecting, or working near battery.
Battery acid can cause permanent blindness.

Charging Battery Installed in Vehicle
TO PREVENT SERIOUS INJURY:
Wear ANSI-approved splash-resistant safety goggles and heavy-duty rubber work gloves
whenever connecting, disconnecting, or working near battery.
Battery acid can cause permanent blindness.
1. If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make
sure all accessories in the vehicle are off, so as not to cause an arc.
2. Make sure area around battery is well ventilated while battery is being charged.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
4. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill.
For a battery without removable cell caps, such as valve regulated lead acid batteries, carefully follow manufacturer’s
recharging instructions.
5. Study all battery manufacturer’s specific precautions while charging and recommended rates of charge.
SHORTED BATTERIES -
will read on Charge Meter as a high end peg at beginning of charging process. If after
5-10 minutes, needle does not move off high end, the battery probably has a short circuit. Unplug charger and
discontinue use. Have battery checked by a qualified technician.
COLD BATTERIES -
begin charging at a low rate, increase as battery reaches a normal temperature, then rate will
decrease normally.
DO NOT CHARGE A FROZEN BATTERY.
BATTERIES WITH HYDROMETER EYE:
Do not depend on hydrometer eye to determine battery charge level.
1. Position AC and DC cables 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.
1. Locate charger as far away from battery as DC cables permit.
2. Never place charger directly above battery being charged; gases from battery will corrode and damage charger.
3. Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
4. Do not operate charger in a closed-in area or restrict ventilation in any way.
5. Do not set a battery on top of charger.
5. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +)
ungrounded post of battery. Connect NEGATIVE (BLACK) clip 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.
NOTICE: If the Reverse Connection indicator lights, the cables are connected improperly. Immediately
disconnect the cables and connect them properly to prevent damage to the battery.
