3. Structure
The battery consists mainly of positive plates, negative plates, separators, electrolyte, valves, a
container and a cover. The electrolyte is absorbed in both positive/negative plates and
separators. Here a container and a cover meet the requirements of UL1778(UL94V-0).
4. Characteristics
The following characteristics are for the batteries, which are manufactured within 6 months.
4.1 Capacity
If the battery is discharged at 2.25A to the end voltage of 10.5V per battery after a full charge,
followed by standing of one hour at an ambient temperature of 25±2℃, the discharge
duration time should exceed 170 minutes within the first 3 times of the charge and discharge
cycles.
See Table 4 for the characteristic data when the battery is used under the condition of
constant wattage load.
Note: Values shown in the table are reference data.
4.2 Shelf life characteristics
The duration time should be more than 80 minutes when the battery, which has been stored at
an ambient temperature of 40±2℃for 4 months, is then stored at an ambient temperature of
25±2℃for 24 hours and is then discharged at 2.25A to the end voltage of 10.5V per battery.
4.3 Trickle life
If the battery is fully charged with a constant voltage charger with the controlled voltage of
13.7±0.10V at an ambient temperature of 25±2℃, and every 3 months the battery is
discharged at a constant current of 2.25A to 10.5V at an ambient temperature of 25±2℃, the
battery shall have a trickle life of over 3 years with a discharge duration of over 1.5 hours.
Note: the expected life of the battery shall decrease by one-half with each rise in temperature
of 10℃. In particular, the life of the battery will shorten remarkably at about 40℃. Therefore
careful consideration must be taken not to use the battery at high temperature. Also, as
mentioned in 4.3 above, the life of battery will vary depending on the charge/discharge
conditions. For example, a non-flat current may shorten the life of the battery. Thus if special
2
2009. 12
UP-PW1245
charge and/or discharge methods not described in this specification will be used, please
confirm the battery characteristics with the actual application equipment before designing the
charger.
As the period of use of VRLA battery becomes longer, the run time of the battery gradually
becomes shortened. While the battery reaches the end of life with the shortened run time,
such phenomena as gradual decrease of electrolyte and corrosion of the positive grid occur
inside of the battery. If the battery of this condition continues to be used, it may suffer from
thermal runaway (a vicious circle of increasing charge current and rising temperature) and
electrolyte leakage as its capacity reaches 0. We strongly recommend taking proper
preventive measures such as replacing batteries before any of these phenomena are found. In
addition, if the case is made of metal, please be sure that the battery is insulated against its
metal case with acid-and heat-resistant insulating material so that the battery can not touch
the metal case directly. If the battery continues to be used without proper replacement, or if it
is not insulated properly, it may generate fire. In case you can not replace batteries for some
serious reason, please take some other preventive actions such as stopping charging. Please
see ‘Recommended timing for battery replacement for backup applications’ for more detailed
information.
4.4 Vibration Resistance Characteristics
Vibration resistance characteristics are tested such that a fully charged battery, being in a
right side up position, is subjected to vibrations under the conditions given below. The battery
is then checked visually for damage such as deformation or leakage of electrolyte, and

1. Environments and conditions
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 airtight
container.
Warning
(1) The batteries must be charged using the specified charger 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, incorporate a back-up system other that
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 batteries 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 specified below:
Discharge (operating an application): 5℉~122℉(-15℃~50℃)
Charge: 32℉~104℉(0℃~40℃) Storage: 5℉~104℉(-15℃~40℃)
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
2
2015.03
cause the batteries to generate excessive heat, leak or explode.
(3) Do not allow the batteries to be exposed to rain or seawater. If the battery terminals should
get wet, they may corrode.
(4) Do not use or store the batteries in a car under the blazing 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 application requiring more than one battery, first connect 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, 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 accidentally 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 conditions 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 abnormal 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 the migrating plasticizer with the
batteries. Furthermore, avoid using organic solvents such as thinner, gasoline, lamp oil,
benzine and liquid detergent to clean the batteries. The use of any of above materials may
cause the containers and/or the covers (ABS resin) of the batteries to crash and leak. There
may be possibilities for the batteries to generate fire in the worst case. 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.

2015.03
(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 or fire 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 equipment, consider the best position for easy
checking, maintenance and replace ability. In addition, the batteries should be located in the
lowest part of the equipment as possible. The rechargeable Valve Regulated 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 position,
the mark “Panasonic” on the battery is turned upside-down. The drawings are only for
explanation of the battery’s position; therefore these are not equal to the real appearance of
the battery that the specifications describe.
Can be used in the vertical position and the side-down position. (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 damage to them. Especially under
the condition of low temperature, with particular attention to operation
(5) Be aware the batteries are relatively heavy compared to their volume. Not to be so may
cause 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.

(8) Place the necessary insulating covers over the terminals, the connecting bars, and bolts
and nuts to prevent a dangerous 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’s to avoid the influence of vibration and/or
physical shock. When the total product of equipments of battery installed in public、normal
capacity of batteries and the amount of container is more than 4800amp/cell,sometimes there
are regulations in law about the ground structure as installing batteries and management
benchmark of battery’s equipments and so on.
Request
(1) A certified technician should install the batteries.
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 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 fire.
Caution
(1) Do not plug the batteries directly into the outlet or the cigarette receptacle of a car without
inserting a charger between the batteries and the outlet or the receptacle. To do so may cause
electrolyte leakage, heat generation, or explosion of the battery.
(2) Turn off the circuit switch when the connections between the batteries and the
charger/load are made.
(3) When using the batteries for the first time, check for rust, heat generation, or any other
abnormalities. If found, do not use as it may cause electrolyte leakage, heat generation, or
explosion.
Request
(1) 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.
5
2015. 01
As following, there is relation between storage time and temperature without charging
batteries:
Below 20℃ :9 months
Below 20-30℃ :6 months
Below 30-40℃: 3 months
Check for the following conditions before to recharge:
Charge method
Charging condition (at 77℉,25℃)
Constant voltage
*Regulation range of the controlled voltage:
7.25V to 7.45V/6V battery, 14.5V to 14.9V/12V battery;
Initial current:0.1CA to 0.4CA;
Maximum charging time: 24hours.
*Short-time charge is possible when several batteries of the
same model, under the same storage conditions can be charged
in series. Otherwise they can be charged separately.
*Charging current:0.1CA
Constant current
*Charging time (hours)
=[Amount of self-discharge (Ah)/0.1CA] X 120%
Rough estimation of amount of self-discharge is as follows
(for an example):
When the storage ambient temperature is lower than 77℉
(25℃), and storage time is known, assume the following
amount of self-discharge:
[5%/month] X storage months
Multiply this by the rated capacity (at 20 hours rate) of the
battery.
*Regardless of the above calculation, the charge time for a
refresh charge must be less than 12 hours.
*When the storage ambient temperature is higher than 77℉
(25℃), please consult Panasonic.
4.Unspecified use
Caution
(1) Do not place the batteries in an unspecified use or they may leak, generate heat, or
explode.
5.Methods of handle and operation
Danger
(1) Do not directly connect the positive and negative terminals with conductive materials such
as a wire. Be careful while using a metal tool such as a wrench and/or carrying the batteries
with metallic necklaces and hairpins to prevent a short circuit.
A short of the battery’s terminals may cause heat generation, explosion or fire.
Warning
(1) Never dispose of the batteries in a fire as it may cause them to explode or generate a toxic
gas.
(2) Do not attempt to disassemble the batteries as it could cause leakage of sulfuric acid and
body injure.
6
2015. 03
Caution
(1) To prevent accidents from happening, change any battery that is found to have an
abnormality such as crack, deformity, or leakage. The batteries must be kept clean and free
from dust to prevent loss of capacity or accident.
(2) If any abnormality of the charge voltage or the discharge voltage is detected, replace the
batteries with new ones.
(3) Charging the batteries with an inverse polarity connection between the batteries and the
charger could cause electrolyte leakage, heat generation, or a fire.
(4) Do not solder directly on the batteries’ terminal tabs. Soldering directly on the batteries’
terminals may cause leakage of electrolyte. Consult Panasonic when soldering is necessary.
(5) Avoid the use of the batteries differing in capacity, type, or history of use
(charge/discharge operation). These differences could cause electrolyte leakage or heat
generation.
(6) Do not remove or scratch the outer tube of the battery or it may cause an electrolyte
leakage or electrical leakage.
(7) Do not allow the batteries to be subjected to any strong physical shocks or jolts while
moving them. Treating the batteries roughly could cause leaks, heat generation, or explosion.
(8) Do not charge the batteries beyond the amount of the time indicated in the specifications,
or do not charge after the charge indication lamp indicates a full charge. Take the batteries off
the charger if the charge is not finished after the specified charge time. Over-charging can
cause leakage, heat generation, or explosions.
(9) Children should be taught how to handle and use the batteries correctly.
(10) Keep the batteries out of the reach of small children at all times.
Request
(1) The cut-off voltage during discharge should vary depending on the discharge current. Do
not discharge the batteries lower than the recommended cut-off voltage shown in Panasonic
specifications or Panasonic technical handbooks. Recharging a battery which was, once
discharged below the recommended cut-off voltage, may generate heat, resulting in the
deformation of the battery or in condensation around the battery cover caused when moisture
within the battery evaporates. In addition, the efficiency of the battery would eventually
decrease.
Over-discharging a battery may result in reduced performance. Always recharge the batteries
immediately after discharge even if the batteries were not discharged to the recommended
cut-off voltage. If the batteries are not charged soon after discharge, the battery performance
may be reduced due to the so-called “sulfation phenomena”.
Note: the cut-off devices to prevent over-discharge should cut off all discharge current
including any weak current.
(2) Thoroughly study the charge methods and the conditions of the batteries before adopting
other charge methods, which are not shown in the Panasonic specifications or the Panasonic
technical handbook, for safety reason
(3) Measure the total voltage of the batteries during trickle charge (or float charge), using a
voltage meter with the accuracy of Class 0.5 (Japan Industrial Standard). If the total voltage of
the batteries provide an indication deviating from the specified voltage range, be sure to
investigate the cause. If the total voltage is lower than that specified, the batteries may lose
their capacity because of a lack of sufficient charge. However, if the total voltage is higher
than that specified, the batteries may lose their capacity by damage due to overcharge and
7
2015. 03
may suffer from “thermal run-away” and other accidents.
(4) Switch off the equipment after use to prevent loss of performance or shortened life of the
batteries due to damage over-discharges.
(5) When storing the batteries, be sure to remove them from the equipment or disconnect
them from the charger and the load to prevent over-discharge and loss of capacity. Before
storing batteries, charge the batteries fully. Do not store batteries in a highly humid place to
prevent rust from forming on the terminals.
6. Maintenance
Warning
(1) When cleaning the batteries, use a soft damp cloth. A dry cloth may cause static electricity,
which could result in a fire or explosion.
(2) Replace batteries with the new ones before the end of their useful life as determined in the
specifications. When the batteries near the end of their life (50% state of their initial discharge
duration time) will shorten remarkably. Finally the batteries will lose their available capacity
by either drying out their electrolyte (causing increase in their internal resistance) or an
internal short circuit. In such case, if the batteries go on charging, thermal runaway and/or
leakage of electrolyte may occur. The batteries should be replaced before becoming in these
states.
The expected life of the batteries (in trickle or float use) will decrease to half (50%) with each
18℉(10℃)rise in temperature above 77℉(25℃). In particular, the life of the batteries will be
shortened remarkably at approximately 104℉(40℃). Accordingly, precautions are required to
prevent the use of batteries at high temperatures.
Caution
(1) Avoid using organic solvents such as thinner, gasoline, lamp oil or benzene and liquid
detergent to clean the batteries. These substances may cause the battery containers to crack or
leak.
Request
(1) Keep the battery terminals clean in order to avoid interruption in the discharge and/or to
maintain the charge.
7. Treatment at emergency
Warning
(1) The batteries have toxic liquid-dilute sulfuric acid solution in them. If the acid comes into
contact with skin or clothes, wash skin or cloth with lots of clean water to prevent scalding
from occurring. If the acid should come into contact with the eyes, wash the eyes with lots of
clean water and consult a physician immediately to prevent possible loss of sight.
Caution
(1) Check the batteries visually for any sign of irregularities in appearance. If any damage
exists such as cracks, deformation, leakage of electrolyte, or corrosion, the batteries must be
replaced with the new ones. Irregularities in the batteries could result in bodily injury,
electrolyte leakage, excessive heat generation or explosion, if used. Furthermore, make sure
the batteries are clean and free from dirt and dust.
8.Storage
8
2015. 03
Caution
(1) Store the batteries in a fixed position separate from metal or other conductive materials.
(2) Keep the batteries from rainwater that could cause corrosion on the terminals of the
batteries.
(3) Keep the batteries right side up during transportation and do not give any abnormally
strong shock and jolt to the batteries. Transporting the batteries in an abnormal position or
handling them roughly could destroy the batteries or cause their characteristics to deteriorate.
(4) When storing the batteries, be sure to remove them from the equipment or disconnect
them from the charger and the load, then store them at room temperature or lower temperature.
Do not store the batteries at direct sunlight, higher temperature or high humidity atmosphere.
To do so cause the batteries short life, performance deterioration or corrosion on terminals.
Request
(1) Charge the batteries at least once every six months if they are stored at 77℉(25℃). Use
the charge method specified in “3.Preparation prior to use”. The interval of this charge should
be reduced to 50% by each 18℉(10℃) rise in temperature above 77℉(25℃).
The self-discharge rate doubles for each 18℉(10℃) in temperature. If they are stored for a
long time in a discharged state, their capacity may not recover even after charge. If the
batteries are stored for more than a year at room temperature, the life of the batteries may be
shortened.
(2) Store the batteries starting from the fully charged state to prevent the life of the batteries
being shortened.
(3) Use the batteries as quickly as possible after receiving them as they gradually deteriorate
even under proper storage conditions.
9. Disposal and Recycling
Caution
(1) Please write the information about battery recycling on the equipment, the package, the
carton, the instruction manual, etc. in countries where legal or voluntary regulations on
battery recycling are applicable.
(2) Design the equipment such that exchange and disposal of the batteries can be undertaken
easily.
(3) Used batteries should be recycled, when returning used batteries, insulate their terminals
using adhesive tape, etc, even used batteries still have electrical charge and an explosion or a
fire may occur, if proper insulation is not given on the terminals of the used batteries.
10.Recommended timing for battery replacement for backup applications
Why do I have to replace batteries?
As the period in use becomes longer, the run time gradually becomes shortened. When the
runtime becomes shortened and its life comes to an end eventually, deterioration of the battery
such as internal short circuit, poor electrolyte and positive grid corrosion results inside of the
battery. If the battery continues to be used in this condition, the electrolyte leakage and/or
thermal runaway may result in the battery while its capacity reaches 0. Before any of these
phenomena is found, preventive measures such as replacing batteries should be taken.

Without such preventive measures, what will happen?
If no preventive measures are taken, there may be a possibility of the battery to generate fire
in the worst case. One of the mechanisms to generate fire is stage 1. positive electrode grid
corrosion, 2. damaged on the battery case caused by its own expansion due to the corrosion,
3.electrolyte leakage, 4. generation of fire. Another is 1. positive electrode grid corrosion,
2.internal short-circuits due to the corrosion, 3. arch , 4. generation of fire.
In order to avoid the worst consequences, please make sure that your batteries are properly
replaced at regular intervals. In case the battery can not be replaced for some reason, stop
charging the battery immediately.
How can I identify proper replacing intervals for my battery?
Please see the table for the proper intervals in replacing batteries.
Replacing timing differs depending on a temperature of the battery surface. The interval for
replacement becomes shortened approximately half as much every time the temperature rises
by 10℃(18℉). In identifying the specific replacing time for your specific battery, please
refer to the ambient temperature of the battery.

Note: The temperatures in the table are ambient temperatures of VRLA batteries.
If you keep charging the battery over the years in the table, the battery will lose the capacity
and may generate fire. The numbers of the years in the table are different from its guaranteed
battery life or expected battery life as an average life assumed through high temperature lab
tests.
We recommend early battery replacement for backup operation even before the time show in
the table has passed.
In case the battery continues to be used after its proper replacement timing because of
negligence, we are not liable for any damaging consequences such as fire and smoke caused
by the battery.
Please understand this and take proper preventive actions.
11.The battery of environmental protection using time limit about UPS
(1)Environmental protection using time limit is showed in table 3.It differs depending on a
temperature of the battery surface, the environmental protection using time limit should be
reduced to 50% by each 10℃ (18°F) rise in temperature.
