2.6
Be extra cautious to reduce risk of
dropping a metal tool onto battery.
It might spark or short-circuit
battery or other electrical part that
may cause explosion.
2.7
Remove personal metal items
such as rings, bracelets,
necklaces, and watches when
working with a lead-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.
2.8
Use charger for charging 12V
LEAD-ACID (STD and AGM)
rechargeable batteries. It is 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.
2.9
NEVER charge a frozen battery.
3. PREPARING TO CHARGE
3.1
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.
3.2
Be sure area around battery is well
ventilated while battery is being
charged.
3.3
Clean battery terminals. Be careful
to keep corrosion from coming in
contact with eyes.
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.
3.6
Determine voltage of battery by
referring to car owner’s manual
and make sure that output voltage
selector switch is set at correct
voltage. If charger has adjustable
charge rate, charge battery initially
at lowest rate.
4. CHARGER LOCATION
4.1
Locate charger as far away from
battery as DC cables permit.
4.2
Never place charger directly above
battery being charged; gases from
battery will corrode and damage
charger.
4.3
Never allow battery acid to drip on
charger when reading electrolyte
specific gravity or filling battery.
4.4
Do not operate charger in
a closed-in area or restrict
ventilation in any way.
4.5
Do not set a battery on top of
charger.
5. DC CONNECTION PRECAUTIONS
5.1
Connect and disconnect DC
output clips only after setting
any charger switches to “off”
position and removing AC cord
from electric outlet. Never allow
the clips of charger to touch each
other. Clips may be energized and
they may spark.
5.2
Attach clips to battery and chassis,
as indicated in sections 6 and 7.
