• Do not place or store the
battery in an automobile in
hot weather, under direct
sunlight, in front of a stove,
or near fire. Use or storage of the
battery in these places may cause fire
or bursting.
• Use of the battery in a dusty
environment is not recommended, as
it may cause the battery to short. The
battery should be periodically
checked when used in such an
environment.
•Avoid sudden movements or
applying shocks to the battery e.g.
from dropping the battery. Damage
and deterioration of battery
characteristics may occur if the
battery is dropped.
• Carefully check the life characteristics
of the battery when in actual loaded
mode. Life of the battery may vary
greatly depending on
charge/discharge conditions.
Installation
• Insulate metallic tools such as
screwdrivers and wrenches with a
vinyl tape, etc. Using non-insulated
tools may cause a short circuit, and
the heat or sparks generated by the
short circuit could result in burns,
damage to the battery, or ignite an
explosion.
• Do not place the battery in a
closed room or near fire.
Placing the battery in such a
location could result in an
explosion or fire due to hydrogen gas
emitted by the battery.
• Avoid using organic solvents such as
thinner, gasoline, lamp oil, benzene
and liquid detergent to clean the
batteries. The use of any of the above
materials may cause the containers
and/or the covers of the batteries to
crack and could ignite.
• Avoid placing the battery in
an environment that is
susceptible to floods. There
is the possibility that if the
battery is immersed in water, it may
ignite or cause electric shocks to
personnel.

NOTICE
• When loading the battery in
equipment, mount it in the lower
most section of the equipment in
order to ensure easy checking,
maintenance and replacement. Do not
charge the battery in the inverted
(upside-down) position: overcharging
in the inverted position may cause
battery leakage from the safety valve.
• Do not carry the battery by hanging it
from the terminal or the lead wire, as
it may cause damage to the battery.
• When carrying the battery, exercise
caution not to apply a strong shock to
it by dropping it, jarring it or causing
it to collide with other objects, as this
may cause damage to the battery.
• Do not underestimate the weight of
the battery. As it is heavy for its
volume, careless handling of the
battery may cause backache or other
injuries to the operator.
• Do not cover the battery
with a material that
generates static electricity,
such as a PVC sheet. A static
charge may trigger fire or explosion.
• In fastening bolts and nuts of the
battery, do not over tighten:
otherwise, damage of the terminal
may occur.
• Apply insulation covers to
terminals, joint parts, bolts
and nuts of the battery in
order to prevent electric
shocks to personnel.
• Fasten the batteries firmly to the
equipment to avoid the influence of
vibration and/or physical shock.
Skilled personnel (specialists) such as
personnel qualified for maintaining
battery equipment should install the
battery and/or equipment. Handling of
the battery by unskilled personnel may
lead to dangerous errors.
Preparation Prior to
Operation
Be sure to provide enough
insulation around the lead
wires and/or plates used between the
batteries and the application.
Insufficient insulation may cause an
electric shock, heat generating from a
short circuit (or excess current) may
result in an injury, burn, smoke or
ignition.

Installation Manual
• Do not connect the battery directly to
a power outlet or a cigarette lighter
socket of an automobile without
using a charger. Direct connection to
power sources may cause battery
over heating or bursting.
• Turn off the switch of the circuit
when connecting the battery to a
charger or a load.
• If newly purchased batteries
exhibit any irregularities in
initial use, such as rusting,
over heating or other
problems, they should not be used.
Continued use of an irregular battery
may lead to fire or bursting of the
battery.
NOTE: Since the batteries tend to lose
a part of their capacity due to self-
discharge during shipment and
storage, recharge the batteries before
you use them after purchase or long-
term storage in order to restore their
full capacity.
Method of Use
• The batteries must be
charged using the specified
charging conditions
indicated in this manual. If
the batteries are charged under
conditions other than those specified,
they may ignite or explode.
• Do not connect the (+) and (-)
terminals of the battery to each other
with a metallic material such as wire;
do not allow tools such as pipe
wrenches and wrenches to touch
points of different voltages on the
battery; and do not bring metallic
necklaces or hair pins into contact
with the battery or store them
together with the battery. Failure to
observe these precautions may cause
the battery to overheat, emit
hydrogen gas, ignite, or burst.
• Do not throw the battery in
fire nor heat the battery. The
battery may burst or
generate a toxic gas if placed
in contact with fire.
• Do not attempt to disassemble,
remodel or destroy the battery, as it
may cause battery leakage, fire or
bursting, and could also create
sulfuric acid spills from the battery
resulting in possible burns to
personnel and damage to the
immediate environment.

• Check the battery for any sign of
irregularities in appearance. If there is
any damage to the battery case/cover
such as cracks, deformation or
leakage, replace the battery with a
new one. If the battery appears dirty
or dusty, clean it. If a battery of
irregular appearance continues to be
used, decrease of capacity, leakage of
electricity, fumes, ignition or other
problems may result.
• If any irregularity is found in areas
such as the charge voltage and
discharge characteristics of the
battery, replace it.
• For safety, make sure to observe the
following: Otherwise, leakage,
ignition or an explosion of the battery
may occur.
- Do not charge the battery with its
(+) and (-) terminals and the (+)
and (-) terminals of the charger
connected in reverse.
- Do not apply a solder directly to
the battery terminals.
- Avoid mixed usage of batteries
differing in type, manufacturer or
history of use.
- Do not remove or damage the
outer case of the battery.
- Do not apply strong shocks or
jolts to the battery.
• Do not continue to charge
the battery beyond the time
specified in the instructions
of use of the charger. If the
battery is not fully charged even after
being charged for a longer time than
specified, discontinue charging and
remove the battery from the charger.
Charging for a longer time than
specified may cause the battery to
ignite or burst.
• Do not discharge the
batteries beyond the
maximum values indicated in
the specifications. If the
batteries are discharged beyond the
maximum values, they may ignite or
explode.
• Children should only use the battery
under the guidance of an adult who
should thoroughly instruct the child
on its use. During use the adult
should check that the battery is used
exactly as instructed.

PROPOSITION 65
WARNING
Battery posts, terminals, and related
accessories contain lead and lead
compounds, chemicals known to the
State of California to cause cancer and
reproductive harm. Wash hands after
handling.
• Avoid over-discharge, and charge the
battery immediately after discharge.
The instruction manual of the
equipment should contain
information telling the user not to
over-discharge the battery and to
charge the battery immediately after
the use of the equipment (discharge).
Even if discharge of the battery is
stopped before voltage decreases to
such a level that the battery-driven
equipment stops being operational,
deterioration of the battery may be
accelerated by the sulphation
phenomenon if it is not recharged
after use. The low voltage cut-off
circuit should be designed so that it
can completely cut off the discharge
current including a weak current.
• If a charge method and a charge
condition other than that described
in the specification and the technical
brochures is to be adopted,
charge/discharge characteristics and
life characteristics of the battery
should be thoroughly checked in
advance. The adoption of adequate
charge methods and adequate charge
conditions are crucial to ensure safe
use of the battery and for fully
utilizing the battery capacity.
• For the cycle operation of the battery
(application of the battery as the
main source of power by repeating
charge and discharge), use a charger
which operates by controlling either
the charge period or charge quantity.
Continue charging the battery for the
time specified or until the charge
completion lamp, if provided,
indicates completion of charge. If
charging is suspended before
completion, the service life of the
battery may be shortened.
• Avoid parallel charging of batteries
in cycle use, as this may shorten the
service life of the batteries by
causing an imbalance in
charge/discharge state among the
batteries connected in parallel.
• During trickle or float charge of the
battery, measure the total voltage
with a high-accuracy voltmeter of
Class 0.5 or better. If the voltage
readout does not meet the specified
value, investigate the reason and
!
NOTICE
take proper measures. A total voltage
that is lower than the specified value
indicates insufficient charge which
may reduce the battery capacity; a
voltage higher than specified
indicates an overcharge which may
shorten service life of the battery or
cause problems such as thermal
runaway in some cases.
• Make sure to turn off the switch of
the battery equipment after use,
otherwise excessive discharge may
cause deterioration in battery
performance and shorten service life.
• When the equipment is not used for a
long period, remove the battery from
the equipment, charge it fully, and
store it in a place where humidity is
low. Unsatisfactory storage conditions
may cause deterioration in battery
performance, shorten service life and
could cause rust to form on the
terminals.
Maintenance and
Checking
• Clean the battery with a slightly damp
cloth, ensure there is no excess water
on the cloth by squeezing it well. Do
not use a dry cloth or a duster, as it
may cause the battery to generate
static electricity, leading to possible
ignition and bursting of the battery.
• Replace the battery with a new one
within the time period specified in the
instruction manual or equipment.
- Follow the guideline which states
the battery should be replaced
when its capacity has decreased to
50% of the initial capacity (at an
ambient temperature of 77°F
(25°C) or below). In the trickle or
float application of the battery
(application as stand-by power) at
an ambient temperature higher
than 77°F (25°C), the period for
which the battery can be used
before replacement is shortened
by a half for every 10°C rise of
temperature. When the discharge
current becomes higher than 0.25
CA, the run time and battery life is
also shortened.
Do not apply organic solvents such as
paint thinner, gasoline, kerosene and
benzene or liquid detergents to the
battery. If these are brought into
contact with the battery case, it may
crack, causing leakage.
