CAUTION
 The batteries must be charged under the conditions specified by GS Yuasa. If the
batteries are charged under conditions other than those specified by GS Yuasa, it may
cause the batteries to not charge fully, leak, become hot or ignite and explode. It may also
cause the deterioration of battery life and performance.
 Before installing or using this battery, please read this instruction manual thoroughly and
carefully. Please keep this manual available for future reference. If there are any
questions, please contact GS Yuasa. The improper installation or use of the batteries may
result in short circuiting, electric shock and/or breakage of the batteries.
 This battery is designed for cyclic use.
 To maintain the life performance of the batteries, please use the batteries in a position in
which the terminals are at the top right and bottom left positions as shown below. If the
batteries are placed and used in the normal upright position in which both terminals are at
the top, an imbalance in the charge/discharge reactions may occur. If installed in this
manner, it may become impossible to control charge/discharge cell balancing, thus
resulting in shorter battery life.
Note: Placing the batteries in the upside-down position with terminals facing downward
may cause a leakage of the electrolyte since the regulating valves are located by the
terminals.

Valve Regulated Lead-Acid Battery for Cycle Use
This battery has a system that controls the emission of gas to the outside of the battery by having the
negative plates absorb oxygen gas generated by the positive plates during charging. It has minimal water loss
during charging and requires no watering.
However, a small amount of hydrogen gas will be emitted through the operation of the regulating valves and
by passing through the case and cover of the battery. Please take necessary precautions when handling this
battery.

1. SAFETY PRECAUTIONS
Batteries are different from general consumer electronics. Energy is not only stored as potential energy
inside the battery but is also converted during charging/discharging operations. Due to these reasons, if the
batteries are handled or used improperly, dangerous conditions may arise. To ensure safety, proper
handling and maintenance of the batteries is necessary. In this instruction manual, warning symbols are
used to indicate that the failure to follow the instructions may result in bodily injury. As shown below, there
are three different symbols that indicate the degree of danger- Danger, Warning, and Caution. Please fully
understand the warning symbols and their meanings before reading the rest of the instruction manual.
DANGER The danger symbol indicates imminently hazardous conditions in which serious
injury or death may occur if this warning is ignored.
WARNING The warning symbol indicates that serious injury or death could possibly occur,
and slight injury or damage to the products often occurs if this warning is ignored.
CAUTION The caution symbol indicates that injury may occur or damage to the products
may occur.

2.2. Battery storage
The batteries gradually lose their capacity, even if they are not used, due to self-discharge. Please charge
the batteries according to the instructions shown in Section 4.1. The charging requirements may vary
depending on the temperature of the storage area. Please refer to Table 2 below as a guideline. If possible,
the batteries should be stored in a dry place and at a low temperature.
Table 2 Guideline for Charging Intervals
Storage Temperature 25℃ or less 30℃ or less 35℃ or less 40℃ or less
Fresh Charge Interval Within 6 months Within 4 months Within 3 months Within 2 months
WARNING
Please ventilate the battery storage area. The batteries emit hydrogen gas even at rest, which
may cause fire or explosion if not ventilated.
CAUTION
When storing, disconnect the batteries from the load and the charger and store in the conditions specified in
the Installation Environment section. Charge the batteries to compensate for self-discharge. Failure to do so
may result in the breakage or deterioration of the batteries.

3. INSTALLATION
3.1. Installation and Installer
CAUTION
Batteries should be installed by professionals such as certified technicians. Installation by less qualified
personnel may result in improper installation.
3.2. Material used for Installation
WARNING
 The battery case and cover should not come in contact with the following materials:
coated wires or sheets that are made of soft vinyl chloride or rubber containing
plasticizer; organic solvents such as benzene, thinner, or gasoline; detergent
containing a surfactant; chemically treated cleaning cloths; or oils. The use of any of
the above materials may cause the battery case and/or the cover to crack, which may
result in leakage.
 Metal tools such as torque wrenches and
other wrenches used to install the batteries
should be insulated. If an un-insulated metal tool comes in contact with the area
between the positive terminal (+) and the negative terminal (-), it may cause a short
circuit, which may result in injury, burn, breakage, and ignition or explosion.
CAUTION
Do not use plastic sheets to cover the batteries, as they may cause static electricity that
may result in an ignition or explosion.
3.3. Installation Environment
DANGER
 Ventilate the room to keep the concentration of hydrogen in the air less than 0.8%.
Hydrogen emitted from the batteries may cause ignition or explosion if the room is not
ventilated. Make sure that the airflow moves the hydrogen throughout the room evenly,
leaving no area with a high hydrogen concentration.
 Do not install batteries near a flame, as this may cause ignition, explosion or fire.
CAUTION
The standard operating temperature for this battery is –15℃ ~+45℃. Usage outside of this range may
cause the batteries to deteriorate quickly. It may also cause batteries to freeze or heat up, resulting in
breakage or deformation. Store the battery in an air-conditioned facility and keep the temperature
between +5℃ and +30℃ if possible. Cells within a string should be maintained within 5°C of other cells
in that string. Temperature differences may result in decreased battery life.

４
CAUTION
 Do not use batteries in the areas that they would get exposed to direct sunlight, as this
may cause the deterioration of the batteries.

Do not allow the batteries to come into contact with seawater. If this happens, the
batteries may be damaged or catch on fire. It may also cause the corrosion of the
terminals and connecting plates (or wires).
 Do not use batteries near a heat-generating device. Doing so may cause the
breakage or deterioration of battery life and performance.
 Do not use the batteries in a dusty area, as dust may cause short-circuiting.
As a general rule, batteries are stored in metal case which GS Yuasa designated. By necessity, use it
anything other than GS Yuasa designated metal case, please be careful about following points.
1. Please take into consideration temperature increase of battery when designing the
cubicles/cabinet.
2. When placing more than two batteries side by side, leave 1mm to 2mm between the batteries, as
this improves heat release.
3. If batteries are installed in multiple stairs, which are more than 2 stairs, consider the placement of
the batteries to minimize the temperature variation between the top and bottom batteries and
make sure to have good ventilation as well.
If the batteries are to be used for cycle use as a stored electrical energy system as well as
emergency power supply for emergency use, please consult GS Yuasa group.
Batteries should be placed in the lowest part of the equipment when mounted.
Do not install electric switches that may cause sparks near the batteries.
3.4. Installation Area
WARNING
Do not install batteries in the areas where they may come in contact with
water. If the batteries come in contact with water, an electric shock or fire
may occur.
3.5. Installation Method
CAUTION
Please take precautions when carrying the batteries to avoid back pain and injury.

５
CAUTION
To maintain the performance of the batteries, please use the batteries in a position in
which the terminals are in the up-down position as shown below. If the batteries are
placed and used in the normal upright position in which both terminals are at the top,
an imbalance in the change/discharge reactions may arise in the batteries. If this
happens, the charge/discharge operations can not be controlled properly, resulting in a
shorter battery life.
Note: Placing the batteries in the upside-down position with terminals
facing
downward may cause leakage of the electrolyte, as the regulating valves
are located by the terminals.
(Battery Position)
SLR-1000 SLR-500
 Please make sure to place the batteries correctly, connecting the correct poles (+,-).
Connecting to wrong poles with the opposite charge may cause fire or damage to the
batteries.
 Batteries are placed horizontally in GS Yuasa designated metal case. The battery slightly
swells when the internal pressure rises which may shorten battery service life or cause
a burst.
1. If using metal case other than GS Yuasa designated, please use the batteries in a position in which the
terminals are in top right corner and the bottom left and keep the upper surface and the sides of the
battery from expanding not more than 3 mm by placing solid surfaces around the batteries.
2. Before connecting the batteries, clean the terminals with brass wire brush, and apply oxide inhibitor to
prevent future oxidation issues.
3. In order to prevent short circuit, when connecting multiple batteries in series, the most positive battery
should be connected last and connecting all others first to the charger and/or the load: positive pole (+)
of the batteries to the positive terminal (+) of the charger and/or to the positive terminal (+) of the load,
and the negative pole (-) of the batteries to the negative terminal (-) of the charger and/or to the
negative terminal (-) of the load: The charger and the load must be turned off during this process.
CAUTION
Fasten the bolts with the torque specified in Table 3 below.
Not using the correct torque may cause the battery terminals to spark or break.

SLR-500 M10 17.2±2.5｛175±25｝
WARNING
Avoid doing work or putting down metal objects such as wrench on top of the batteries, as
doing so may cause the batteries to break or ignite and explode.
CAUTION
After connecting the batteries, please apply a thin anti-corrosion coating to the connecters and the battery
terminals. Failure to do so may cause the formation of high –resistive corrosion layers in the batteries.
DANGER
Use a damp(pure watered) cloth to clean the batteries. Do not use a duster or dry cloth, as
they may cause static electricity which could result in ignition or explosion.
WARNING
Place the insulation covers over the terminals, connecters, and bolts to prevent an electric
shock.
CAUTION
When painting cubicles/cabinet, floors, or walls, make sure that the paint does not touch the
batteries. The paint may cause the battery case or the cover to crack, resulting in leakage.
3.6. Installation Requirements
1. Please connect the batteries in series for use. If the batteries are connected in parallel and the
charge/discharge cycle is repeated, variations in the charge/discharge amount will arise, especially if
the depth of discharge is high, which may cause an early decrease of battery life. To maximize the
battery life when parallel connections are required, make sure the circuit resistance between each
parallel string is equal, limit the DOD to 50% ideally, and limit the number of parallel strings to 6.
2. This battery is designed for cyclic use. Please contact GS Yuasa for charger settings for applications
which require both emergency power supply and cyclic use.

4. SUPPLEMENTARY CHARGE and TRIAL RUN
4.1. Supplementary Charge (Top Charge)
CAUTION
The batteries should be handled by professionals such as certified technicians. If handled by
un-qualified personnel, mistakes may occur.
The battery gradually loses its capacity during transportation or storage due to self-discharge. Please
charge the battery with constant current at 0.5× I10 (0.05 C10 ) for 4 to 8 hours prior to use.
Note: “I10” in a current value denotes a 10-hour rated discharge current, “C10” denotes a
10-hour rated capacity.
CAUTION
 A supplementary charge (top charge) should be given to the batteries under the
specified conditions by using the charger specified by GS Yuasa or the one included
with the equipment. Using without charging may result in an insufficient load. If the
batteries are charged under the conditions other than those specified by GS Yuasa, it
may cause the batteries not to charge fully, or cause leakage, heat generation and
ignition or explosion, or may cause the deterioration of battery life and performance.
 Keep the surface temperature of the batteries below 50℃ as much as possible when
performing a refresh charge. If the surface temperature rises above 50℃, it may cause
the batteries to break or deteriorate. Please stop performing a refresh charge to
prevent the rise of the battery temperature when there is a risk that the
temperature rises above 50℃.
Note: At the time of delivery or during performing a refresh charge, a part of the battery case may
appear sagged or expanded slightly. However, this is normal. It is acceptable to use the
batteries with these conditions. However, please contact GS Yuasa if the condition worsens
during charging.
4.2. Trial Run
1. When conducting the performance tests for the batteries or batteries coupled with a load or a
charger, follow the procedures in Section 5 and Section 6.
2. Charge the battery according to Section 4.1 before the trial run.
3. If not using the batteries immediately after the trial run, store the battery according to Section 2.2.
4.3. Preparation Prior to Operation
Please charge the batteries according to Section 4.1, if the batteries are not used immediately after
charging or after trial run.
