Preparing To Charge; Charger Location; Dc Connection Precautions; Follow These Steps When Battery Is Installed In Vehicle - Schumacher SC1591 Owner's Manual

Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-
2.7
acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to
metal, causing a severe burn.
Use charger for charging 12V LEAD-ACID (STD, AGM, GEL or deep-cycle) rechargeable batteries. It is
2.8
not intended to supply power to a low voltage electrical system other than in a starter-motor application.
Do not use battery charger for charging dry-cell batteries that are commonly used with home appliances.
These batteries may burst and cause injury to persons and damage to property. When charging the
internal battery, work in a well ventilated area and do not restrict ventilation in any way.
NEVER charge a frozen battery. Under abusive conditions, liquid may be ejected from the battery; avoid
2.9
contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause irritation or burns. Do not expose a power pack to fire or
excessive temperature. Exposure to fire or temperature above 13°C (265°F) may cause explosion.
Have servicing performed by a qualified repair person using only identical replacement parts. This will
2.10
ensure that the safety of the product is maintained.

PREPARING TO CHARGE

If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery
3.1
first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
Be sure area around battery is well ventilated while battery is being charged.
3.2
Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
3.3
3.4 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.
3.5 Study all battery manufacturer's specific precautions while charging and recommended rates of charge.
Ensure voltage of the battery is 12V by referring to the vehicle's owner's manual.

CHARGER LOCATION

Locate charger as far away from battery as DC cables permit.
4.1
Never place charger directly above battery being charged; gases from battery will corrode and damage charger.
4.2
Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
4.3
Do not operate charger in a closed-in area or restrict ventilation in any way.
4.4
Do not set a battery on top of charger.
4.5

DC CONNECTION PRECAUTIONS

Connect and disconnect DC output clips only after setting any charger switches to "off" position and
5.1
removing AC cord from electric outlet. Never allow clips to touch each other. Clips may be energized and
may spark.
Attach clips to battery and chassis, as indicated in sections 6 and 7.

FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.
6.1
Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
6.2
Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than
6.3
NEGATIVE (NEG, N, –) post.
Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to
6.4
chassis (as in most vehicles), see (6.5). If positive post is grounded to the chassis, see (6.6).
For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +)
6.5
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.
