7. Battery Handling Precautions
CAUTION
•
Risk of explosion if battery is replaced by an incorrect type
•
Dispose of used batteries according to the instructions.
•
Battery servicing should be performed by technically qualified personnel. Keep unqualified personnel away
from batteries.
•
Replace batteries only with the same model and brand: HRL1234WF2FR manufactured by CSB BATTERY
Co., LTD.
•
Customers should not dispose of used batteries themselves. Contact your nearest sales representative,
authorized service center or sales office to dispose of used batteries.
•
Do not use batteries after their service life has expired. Doing so may result in fuming or fire. Additionally,
the battery backup function may fail to operate with such batteries, so that power will not supplied to the
load when a power outage occurs.
•
Batteries pose hazards for electrical shock and dangerous short-circuit current. The following precautions
should be observed when working with batteries:
a. Remove watches, rings and other metal objects.
b. Use insulated tools.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect the charging source prior to connecting or disconnecting battery terminals.
f. Determine whether the batteries have been inadvertently grounded, and if so, remove the source of
grounding. Contact with any part of a grounded battery can result in electric shock.
•
Do not attempt to open or disassemble batteries. The electrolyte is harmful to the skin and eyes. The battery
contains diluted sulfuric acid, which is extremely toxic. If a battery leaks, take appropriate measures to
prevent any battery fluid contacting your skin or clothing. Diluted sulfuric acid may cause blindness if it
gets into the eye, may burn skin upon contact. It is electrically conductive and corrosive. Observe the
following procedures if electrolyte spills:
a. Wear full eye protection and protective clothing.
b. If sulfuric acid contacts the skin, wash it off immediately with water.
c. If sulfuric acid contacts the eyes, flush thoroughly and immediately with water, and seek medical
attention.
d. Spilled sulfuric acid should be washed down with a suitable acid-neutralizing agent, such as a solution
of approximately one pound (500 grams) bicarbonate of soda in one gallon (4 liters) of water. The
bicarbonate of soda solution should be applied until evidence of reaction (foaming) has ceased. The
resulting liquid should be flushed with water and the area dried.
•
Lead acid batteries can present a risk of fire due to generation of hydrogen gas. The following procedures
should always be followed:
a. DO NOT SMOKE when near batteries.
b. DO NOT allow flames or sparks near batteries.
c. Before working with batteries, discharge static electricity from the body by first touching a grounded
metal surface before touching the batteries.
•
Do not dispose of batteries in fire, as they could explode.
•
If a fire occurs near a battery, do not use water to extinguish it. Use only a powder-distinguishing agent
(ABC). Using water can cause the fire to spread.
•
Strictly observe the following precautions when handling the batteries. Failure to do so may cause battery
leakage, overheating or explosion.
a. Do not solder to any part of the battery directly.
b. Do not charge the battery with reversed positive (+) and negative (-) terminal polarity.
c. Do not mix different battery types, brands or versions.
d. Do not attempt to peel off or break the outer covering of a battery.
e. Do not subject batteries to strong physical shock, or throw them away.
f. Clean batteries with water-moistened cloth. Do not use organic compounds such as gasoline, thinner,
benzene or detergent.
g.
Electrical energy may remain in a battery even after its service life has expired.
Do not allows sparks near used batteries, and protect them from short-circuiting.
