Valve Regulated Lead-Acid Batteries
1 | Precautions for Handling VRLA-Batteries
1. Environment and Condition
DANGER
(1) Do not put the batteries into airtight containers or bags.
The batteries tend to generate inflammable gas upon excess
charge which may cause an explosion if enclosed in an air-
tight container.
WARNING
(1) The batteries must be charged using the specified char-
ger or by maintaining the charging conditions indicated by
Panasonic. If the batteries are charged under conditions
other than those specified by Panasonic, they may leak,
generate excessive heat, or explode.
(2) When using the batteries in medical equipment, incor-
porate a back-up system other than the main battery in the
event of power failure.
(3) Insert insulation that is resistant to heat and sulfuric acid
between the batteries and any metallic housing. Failure to
do so may cause the batteries to smoke or burn in case of
electrolyte leakage.
(4) Do not place the batteries near a device that may generate
sparks (such as a switch or fuse) and do not place the batter-
ies close to fire. The batteries may generate an inflammable
gas when charged excessively that may ignite upon contact
with a spark or they may burn or explode due to sparks or fire.
CAUTION
(1) Use or store the batteries in the temperature range:
Discharge (operating in application): -15°C ~ 50°C.
Charge: 0°C to 40°C. Storage: -15°C to 40°C.
Temperatures above or below those recommended could
result in damage or deformity of the batteries.
(2) Avoid placing batteries near a heat-generating device
(such as a transformer) which may cause the batteries to
generate excessive heat, leak or explode.
(3) Do not allow the batteries to be exposed to rain or sea water.
If the battery terminals should get wet, they may corrode.
(4) Do not use or store the batteries in a car under the bla-
zing sun, in direct sunlight. To do so may cause the batteries
to leak, generate excessive heat, or explode.
(5) Do not use or store the batteries in a dusty place as dust
may cause them to short between their terminals. When using
the batteries in a dusty place, check them periodically.
(6) In applications requiring more than one battery, first con-
nect the batteries together and then connect the batteries
to the charger or the load. Be careful to connect the (+)pole
of the batteries to the (+)terminal of either the charger or
the load. Improperly connecting the batteries, charger, or
load may cause an explosion or fire to occur. In some cases,
bodily injury may occur.
(7) When handling the batteries, wear steel-tipped shoes to
prevent possible injury to the feet if the batteries are acci-
dentally dropped.
REQUEST
(1) Dropping a battery may cause a strong physical shock
that may damage the performance of the battery.
(2) Confirm the life of the batteries using the real load and
charger. Differences in the charging and the discharging con-
ditions may cause a big difference in the life of the batteries.
2. Installation
DANGER
(1) Tools such as wrenches used to install the batteries
should be insulated. Bare metal tools may cause an abnor-
mal short circuit accident to occur resulting in bodily injury,
damage to the batteries, explosion or fire.
(2) Do not install the batteries in a room without ventilation. The
batteries tend to generate an inflammable gas upon excess
charge resulting in an explosion or fire if the room is closed.
WARNING
(1) Do not contact any plastic or resin (*) which contains
a migrating plasticizer with the batteries. Furthermore,
avoid using organic solvents such as thinner, gasoline,
lamp oil, benzine and liquid detergent to clean the bat-
teries. The use of any of above materials may cause the
containers and/or the covers (ABS resin) of the batteries to
crack and leak. This may cause a fire in the worst scenario.
Need to make sure the use of material will not cause the
containers and/ or the covers (ABS resin) of the batteries to
crack due to the migration of plasticizer within the material
by asking the manufacturer of the material if necessary.
* Examples for plastic or resin which should be avoided using:
Vinyl chloride, Oily rubber.
* Examples for plastic or resin which is proper for the use:
Polyolefin resin such as polypropylene, polyethylene.
(2) Always use such as rubber gloves when handling batteries
with the voltages higher than 45 volts in order to prevent
severe bodily injury from occurring.
(3) Do not install the batteries in areas where they may come
in contact with water. If the batteries come in contact with
water, an electric shock may occur.
CAUTION
(1) During unpacking, handle the batteries carefully and
check for cracks, breakage, or electrolyte leakage. Failure to
handle carefully may result in damage due to physical shock.
(2) When the batteries are being mounted in the equip-
ment, consider the best position for easy checking, main-
tenance and replacement. In addition, the batteries should
be located in the lowest part of the equipment as possible.
The Rechargeable Sealed Lead-Acid batteries, mentioned
in this document, are designed for use in any position, but
charging the batteries in the upside-down position should
be avoided. When these batteries are charged excessively
in the upside-down position, leakage of electrolyte from
the rubber vents may occur. The upside-down is shown on
the left side of the next drawings. In this upside-down posi-
tion, the mark “Panasonic” on the battery are turned upside
down. The drawings are only for explanation of the battery’s
position; therefore these are not equal to the real appear-
ance of the battery that the specifications describe.
Can be used in the vertical position and the sidedown posi-
tion (maximum angle of 90 degrees from the normal position).
(3) Do not carry the batteries by picking up them by their
terminals or lead wires. To do so may damage the batteries.
(4) Be careful not to jolt the batteries as it may result in dam-
age to them.
(5) Be aware the batteries are relatively heavy compared to
their volume. Please be careful to carry these batteries in
order to avoid injury and/or lumbago.
(6) Do not cover the batteries with plastic sheet as it may
cause a fire or an explosion by conducting static electricity.
(7) Fasten the bolts and the nuts with the torque as shown
below: Not to do so may cause the battery terminals to break.
(8) Place the necessary insulating covers over the terminals,
the connecting bars, and bolts and nuts to prevent a danger-
ous electric shock.
(9) Please consult Panasonic prior to using the batteries in
applications such as a motor bicycle, an engine driven lawn
mower, etc. which may generate severe vibration.
(10) Fasten the batteries firmly to the equipment to avoid the
influence of vibration and/or physical shock.
REQUEST
(1) The batteries should be installed by a certified technician.
3. Preparation Prior to Operation
DANGER
(1) Be sure to provide enough insulation around the lead
wires and/or plates used between the batteries and the ap-
plication. Insufficient insulation may cause an electric shock
heat generating from a short circuit (or excess current) may
result in an injury, burn, smoke or fire.
CAUTION
(1) Do not plug the batteries directly into the outlet or the
cigarette receptacle of a car without inserting a charger be-
tween the batteries and the outlet or the receptacle. To do
so may cause electrolyte leakage, heat generation, or explo-
sion of the battery.
(2) Turn off the circuit switch when the connections between
the batteries and the charger/load are made.
