BEFORE USE
A. PREPARING TO CHARGE
1. If it is necessary to remove battery from
vehicle to charge, always remove
grounded terminal from battery first.
2. Be sure area around battery is well
ventilated while battery is being charged.
Gas can be forcefully blown away by
using a piece of cardboard or other
nonmetallic material as a fan.
3. Clean battery terminals. Be careful to
keep corrosion from coming into contact
with eyes.
4. 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(ie
Maintenance Free), carefully follow the
battery manufacturer ’s recharging
instructions.
5. Study all battery manufacturer’s specific
precautions such as handling of cell
caps and charge rates.
6. Determine voltage of battery by referring
to car owner’s manual. Make sure that
output voltage range provided by
charger is compatible with the battery
intended to charge.
ALWAYS check
with battery manufacturer for specific
charging rate requirements.
B. CHARGER LOCATION
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 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.
6. Battery used for boats(marine) must be
removed and charged on shore.
f) Be extra cautious to reduce the risk of
dropping a metal tool onto battery. It
might cause spark or short circuit battery
or damage other electrical part that may
cause explosion.
g) 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.
h) Use charger for
charging
a LEAD-ACID
battery
only
. Model I-7002 is not
intended to supply power to a low
voltage electrical system and does not
have engine starting ability as a stand
alone device. Do not use this 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.
i) NEVER charge a frozen battery. Frozen
batteries may burst when charged and
cause injury to persons and damage to
p r o p e r t y . C h e c k w i t h b a t t e r y
m a n u f a c t u r e r f o r f r o z e n b a t t e r y
remedies.
j) Do not overcharge the battery, it will
impact the life time of battery.
Wear protective clothing and safety
goggles to reduce the risk of injury.
