INTRODUCTION
The batteries referenced in this document are valve-regulated lead acid Liberty Series 1000®.
They are constructed with pasted lead calcium plates with an absorbent glass mat and are
valve-regulated.They are designed to provide long, reliable service life with minimal
maintenance. The cells/units are shipped pre-assembled in 2-, 4-, 6- and 12-Volt modules to
enable quick and easy installation. When operated at the recommended float voltage and
temperature, the batteries emit virtually no gas or acid mist and do not need special
ventilation other than what is required by local building codes. This makes Liberty Series
1000 batteries an ideal reserve power source for many critical applications, including
telecommunications, switchgear and control, and uninterruptible power supply (UPS)
systems. The Liberty Series 1000 product brochure and additional information are available
on the C&D Technologies website at www.cdtechno.com.
Recombination: A More Efficient Design
In addition to eliminating the need for watering, the uniquely efficient recombination design
also makes Liberty Series 1000 batteries lighter and more powerful than conventional lead-

SECTION 2 - STORAGE and SHELF LIFE
2.1 Storage of VRLA (valve regulated lead acid) Batteries
Store batteries indoors, preferably at 77°F (25°C) or in a cool 20°F to
90°F (-7°C to 32°C), dry location and place on charge by the
date
found on the battery carton.
Note:
Batteries that are not placed in service for several months will
self-discharge.
Storage time is based on storage at 77°F (25°C) and is six months for
valve regulated cells. Do not allow the electrolyte

to freeze, as this will destroy the battery and can cause a potentially
hazardous condition and leakage.
Refer to Table 1, for electrolyte freezing temperatures. Although the
specific gravity of a fully charged battery may present no freezing
lem, a discharged battery gravity may freeze at relatively mild
prob
temperatures.

acid batteries are warranted against defects in materials or manufacturing or both. To keep the warranty in effect, you must place the units
on charge by the date stamped on the shipping carton when stored at
77°F (25°C). If storage beyond this time is required or storage temperature is in excess of 77°F (25°C), monitor battery voltage at monthly
intervals, if possible. A convenient measurement technique is to read
the open circuit voltage. If the open circuit voltage drops below 2.10
volts per cell from the nominal value, the cell(s) must be given a boost
charge at the “Initial/Equalize” voltage shown in Table 2. With the
exception of the LS 2-600 all units consist of multiple cells. Refer to
Table 2 for the nominal voltage and number of cells for a particular
Liberty Series unit. Ne
ver charge the cells at a higher voltage than the
equalize/ boost voltage recommended in Table 2, at 77°F (25°C). If
cell temperature is below 60°F (16°C), double the initial/equalize
charge time that is typically 12-16 hours at 77°F (25°C).
If this is not possible, contact C&D Technologies, Inc., Technical
Services Department for special instructions.
Always complete a record of initial charge, refresh charges during
storage, and fl
t 2, Section 1.2 using RS-1511 of this manual and retain the
Par
oat charge readings as described in
“initial charge”
readings in your files for future reference. Clearly identify your installation location, application, C&D Technologies model n
umber
, the date,
and name of the person who took the readings.
The ser
vice life of the battery will depend on its ambient temper
ature,
frequency and depth of discharge, discharge rate, charge voltage, and
regulation of the battery charger.

dimensions for layout may be found in Table 2. Install battery in a cool,
dry location away from heat sources.The recommended operating
temper
ature is 65-77
°F (18-25°C). The allowable temperature range
with performance degradation at the extreme temperatures is 32-90°F
(0-32°C). Float voltage compensation should be made for temperatures

battery assembly. Such variations will compromise optimum
battery performance such as float voltages of individual cells.
When handling units never lift them by the terminals as this can
damage the post seals and cause acid leakage.

Therefore, the battery should never be installed in an airtight enclosure. Sufficient
ust be taken to prevent excessive overcharge and containment of potential gases.
VRLA batteries when subjected to extreme overcharge (above the
recombinant ability of the cell) can release hydrogen gas at a
maximum rate of 0.000269 cubic feet per minute per ampere of
charging current at 77°F (25°C) at atmospheric pressure.
3.3 Rack Assemblies
Liberty Series 1000 batteries may be installed in a variety of
mounting assemblies
• Modular Rack assembly (Figure 3.1) - battery units may be assembled in a floor mounted module or rack. One modular rack available
from C&D Technologies, Inc. is designed to mount the units in a
sturdy open frame that is stackable. They are available in 29" and
43" (74 cm and 109 cm) lengths. Optional panels are available to
enclose the racks, providing a cabinet-like appearance. (Figure 3.2)
For additional information refer to specification 12-373 and 12-380.
• When large numbers of batteries are required for the application
and a dedicated battery room may be provided, conventional tiered
ks may be appropriate.

CAUTION
Do not use steel brushes, steel wool, sandpaper or emery cloth
to clean surfaces, as these will damage the plating. Do not use
cleaning solvents. Solvents can cause crazing or cracking of
the plastic cell containers or covers. Use of solvents will void
the warranty.
4. Attach intercell connectors or cable/lugs from the positive post of
one unit to the negative post of the next cell or unit for series
connection. If the units are mounted on more than one tier make
certain to follow the polarity convention, positive post to negative
post. Inter-tier and inter-row connections are typically made with
cables with lugs on both ends. Do Not Use Steel or Cadmium
Plated Lugs.
5. Large batteries may use “Terminal Plates” to accommodate
multiple cable connections.There are a variety of optional terminal
plates availab
le from C&D Technologies, Inc., Inc. Terminal plates
should be clean and prepared in the same manner as the intercell
connectors.
4.2 Polarity of assembled units/cells and inter-row, inter-tier
connections
LS 12-100 Inter-Tier Connection
Cell/unit polarities have been marked by a raised mark in the covers to
provide proper interconnection between cells.When connecting
cells/units be sure that all ter
minals, including inter-tier, have been
connected positive (+) to negative (-) from one cell/unit to another
throughout the battery.
4.3 Connecting and torquing battery terminal posts
Liberty Series 1000 batteries are available in various sizes and volt-
able 2 and with corresponding Ampere-hour
ages as descr
ibed in
T
ratings at the 8 hour rate of discharge: 80 Ah, 100 Ah, 125 Ah, 200
Ah, 300 Ah, and 600 Ah. The units are connected positive to negative
from one unit to another unit in a series arrangement. This is accomplished by fastening the tin plated connector (used on larger size
units) or lugs found on cables (for smaller size units) from the positive
terminal of a unit to the negative terminal of the next unit. The lug or
connector is secured with the appropriate terminal hardware
described in Table 2 and tightened to the torque value specified in
Table 2.
Connect cells/units with the stainless steel hex head bolts and
washers in accordance with the connecting instructions for the
system. Torque all connections to the proper torque value shown in
Table 2.
LS 12-100 Inter-Rack Connection
It is recommended that the top tier of connectors be installed first on
multi-tier racks, then the second and so on, working from the top
down. This may avoid short circuiting connected groups of units in
lower tiers.
13
CAUTION
Use extreme care when installing connectors; maintain a firm
grasp on each connector as it is being installed, to prevent it
from dropping and potentially causing a short circuit.
Note:
Over-torquing can damage the post seal causing electrolyte
leakage.
4.4 Checking connection integrity
• Check once again that all units are connected positive terminals to
negative terminals. Measure the battery voltage with a digital
voltmeter. The voltage should be approximately 2.15 Volts (open
circuit) times the number of cells per unit times the number of units
connected in series. Example: 2.15 Volts x 2 cells/unit (model LS 4-
300) x 6 units = 25.8 Volts, representative of the nominal open
circuit voltage of a 24-Volt system.
• Recheck the torque of connections to make certain that there are no
loose connections that could cause a poor connection thereby
creating an arc or spark or a hot connection that on discharge could
melt the lead components.
• Follow the charger manufacturer’s instructions and make the connections to the battery with the charger de-energized.
CAUTION
It is the sole responsibility of the user to chec
k connections.
All connections should be checked at regular intervals to
ensure that connections are c

Typical internal cell resistance values are provided in Table 2
according to cell type. In addition a listing of short circuit current in
amperes is pro
vided to further inform the user of the potential energy
available from the batteries.
4.5 Paralleling Batteries
When strings of batteries of equal voltage are connected in parallel,
the total capacity is equal to the sum of the capacities of the individual
strings. C&D Technologies recommends parallel strings when the
required capacity exceeds available Ampere-hour sizes or when
physical arrangement favors this choice. The use of parallel strings
permits maintenance on one string while the other(s) remain functional at a somewhat lower reserve time. Limit the number of paralled
battery strings to six.
When paralleling is necessary to obtain required capacity, the cable
size and external cable length should be optimized to match the cable
resistance for each battery. A wide variation in circuit resistance can
result in unbalanced discharging and charging of cells. As a
consequence this can produce unequal float voltages of the
connected cells and individual strings can sustain a loss of
performance and capacity, resulting in higher loads on the other
parallel strings with lower cable (circuit) resistance.

CHARGING AND OPERATION OF BATTERY
SECTION 1 - CHARGING
1.1 General Information and Precautions
To safely charge the Liberty Series 1000 batteries and avoid
damaging the battery and/or connected equipment, observe the
following:
• Use only direct current for charging. AC ripple current from charger
must not exceed 5 percent of the 8-hour (Ampere-hour) rating of the
battery.
• Be sure charger is turned off before making electrical connections
between the battery and system.
• Connect battery positive terminal to charger positive terminal and

Higher than normal storage temperature (77°F [25°C] nominal) will
accelerate internal self-discharge of a battery by a factor of two for
each 15°F (9°C) over nominal 77°F (25°C) storage temperature. This,
in turn, will reduce the allowable time before initial and subsequent
charging.
Therefore it is very important that boost charges be given at the
appropriate time to avoid major remedial action or damage to
product.
All batteries, including Liberty Series 1000, are capable of generating
potentially explosive gases when charged at higher than nor
voltages typical of initial or equalizing charge
. The Liberty Series 1000
mal
cells are equipped with a “flame arrestor and pressure relief valve”

allo
ly that seals the cells during nor
ws it to safely vent in case of overcharge. Removing the cover
mal charge and operation b
ut
and/or valve assembly can cause the release of potentially explosive
gases and such action will v
oid the warranty.
CAUTION
Never expose a cell or battery to sparks or an open flame.
When working on a battery, discharge static electricity on the
body, tools, etc., by touching a grounded surface in the vicinity
of the battery rack.
1.3 Constant voltage charging
The recommended method of providing an initial/equalize charge is to
first determine the maximum allowable voltage that may be applied to
the connected equipment. Divide this by the number of cells in the
battery to obtain maximum average voltage per cell allowed by the
equipment. Adjust this number down to a recommended initial value
found in Table 3 and continue charging at this voltage for the time
specified. Next put the battery at the recommended float voltage for a
17
minimum of 72 hours before any load is placed on the system. The

acceptance testing or regular service.
Use only direct current for charging. AC ripple current from charger
must not exceed 5 percent of the 8-hour (Ampere-hour) rating of the
battery.
1.4 Initial charge records
At the completion of the initial charge and after the cells have been on
float charge for approximately one week, record voltages of the individual cells or units, the total battery voltage and ambient
temperature. Retain this information in your files for future reference.
This information establishes one baseline for future reference. Refer to
RS-1511 found in the appendix. Make a photocopy of the form and
use it whenever necessary to record readings taken on the battery.

1.5 Warning labels
C&D Technologies, Inc., provided a warning label to assist in maintaining standb
y batteries and to advise you of cer
tain hazards.
This label
may be found on the battery cover visible to anyone in the immedi-
ate vicinity of the battery. Make certain that all individuals who could
be oper
ating near the battery read the war
ning that is intended to
inform the individuals of basic safety practices.
SECTION 2 - BATTERY OPERATION
ging
2.1 Float c
har
Standby batteries are continuously connected to control circuits, which
must be energized at all times. Connected to a load in parallel with a
contin
uously oper
ating power supply, these batteries assure
instantaneous support of the load in the event of a power failure or
brownout. In addition to operating the connected load, the power
supply k
eeps the standb
y battery fully charged. This parallel
interconnection and operation is called float service. Maximum battery
life can be expected in full float service, in which the frequency and
depth of discharges are k
ept at a minimum.
18
Deep and/or frequent discharges, such as those in a UPS application,
can shor
ten service life, even with proper battery maintenance.
Maximum battery life can be expected only in full float service.
F
or optimum service, adjust the power supply to the float voltages shown
in Table 3. If the power supply is intermittent or more frequent discharges
are anticipated, use a higher value recommended voltage setting.
Note: For locations that exhibit frequent temperature variations it is
recommended that temperature compensated rectifiers be
used that adjust the voltage in accordance with sub-sections
3.4 and 3.5 of Section 3.
2.2 Equalizing charge
Under normal operating conditions, it should not be necessary to
equalize batteries when charged at the recommended voltage in
Tables 2 and 3. An equalizing charge delivered at a voltage higher
than the nominal float voltage is used to restore uniform cell voltage to
a battery.
Note 1: Some hydrogen gas may be liberated at equalize charging
voltage.
An equalizing charge can be provided when individual cell voltages go
below the minimum value shown in Table 3 or 0.05 Volts below the
minimum float voltage specified in Table 3. Remember to divide the
number of cells into unit voltage to arrive at cell voltage. Presence of a
minimum voltage does not imply a battery is malfunctioning or that it
will not provide the necessary power when called upon.
Note 2: Chargers must be current limited to 25 Amperes per 100-
Ampere-hour battery rating. Higher charging currents could
potentially destro
y the batter
can subsequently cause more current to fl
y by overheating.This heating
ow, creating a
vicious cycle sometimes referred to as “thermal runaway.”
Note 3: Minim
um voltage is the point at which plans should be made
to provide an equalizing charge. Note that the normal equalize voltage level (initial charge level) will not be effective in
VRLA product as the voltage is not high enough to enable the
negative plates to charge. An equalizing charge of 2.45 volts
per cell can be applied to the string or problem cell/unit for a
period not exceeding eight hours. Consult the C&D
Technologies Technical Service Department for answers to
specific questions.
2.3 Over-voltage
When a charger is improperly set or a panel meter is improperly
calibrated battery over-voltage or under-voltage may result. Higher
than normal battery voltage can damage a battery, significantly
shortening its service life. This is especially important in valveregulated product where over-voltage increases gas generation that
could cause pressure build-up within the cell. The excess pressure will
cause the cells to vent the gases generated, causing premature dry out
of the battery electrolyte. Even a small increase in over-voltage,
beyond what is recommended in Table 3, increases the corrosion rate
of the positive grid element and will contribute to reduced battery life.
19
T
o avoid over-voltage, periodically check battery voltage with a
calibrated digital voltmeter. If an over-voltage is recorded, check and
readjust the rectifier and/or panel meter calibration as necessary. Place
the battery at the recommended float charging voltage as soon as
possible. Restoring the proper float voltage will preclude further damage caused by charging at an over-voltage b
ut it cannot reverse dam-
age that has already been sustained by the battery.
CAUTION
Liberty Series 1000 batteries produce virtually no gas
emissions during normal operation. However, potentially
explosive gases may be released under abnormal operating
conditions or initial/equalize charge. Provide adequate
ventilation so hydrogen gas accumulation in the battery area
does not exceed one percent. Do not smoke
, use open flame
or create sparks near battery.
2.4 Voltmeter calibration
Panel voltmeters used in conjunction with float charging systems
should be kept in accur
standard per the man

ate calibr
ation by checking with a kno
acturer’s recommendations. Alw
wn
ays measure
battery voltage at the battery terminals and compare the reading with
the panel meter to eliminate the effect of line drop between the batter
and connected system or charger. Battery voltage should always be

Typically during the last half of the battery service life, performance
will begin to fall slowly at first, then at an increasing rate. Lead-acid
batteries have reached the end of their useful life when performance
has fallen to 80 percent of published ratings.
Note: Frequent charge/discharge cycles accelerate battery aging and
performance degradation.
To insure adequate performance it is recommended that a battery be

perature and for loss of capacity as the battery ages.

.2 Capacity and testing
Batteries are rated in Ampere-hours or kiloWatts on their ability to
deliver a certain number of amperes or power, respectively, to the load
for a specified amount of time before cell voltages drop to a final
design potential. It is important to understand that the ampere-hour
capacity or kiloWatts of a cell or battery depends upon the rate at
which it is discharged. Consult C&D Technologies specification sheet
12-373 for the ratings of various cell types.
C&D Technologies lead-acid batteries and cells are designed for
optimum performance, either as short, high-rate or long, low-rate
discharge batteries. Short, high-rate discharge batteries are typically
discharged to lower end-potentials, such as 1.65 to 1.67 Volts per cell.
These voltages are not practical end potentials for long, low-rate
discharges that normally terminate at 1.75 Volts per cell or higher final
voltages.
It is also important to consider low ambient operating temperatures
when calculating required battery size. Low operating temperatures
will reduce available battery capacity approximately 0.5 percent
per degree F. Refer to Section 3.4 “Effects of Temperature” for
temperature compensation and additional information. To be valid,
a capacity test must be based upon:
• A fully charged battery and balanced cell potentials
require an equalize charge or
, in cases of sulfation, other action.

Technical Service Department located in Blue Bell, PA about testing
procedures and special service requirements.
3.3 Low cell voltages
With proper float operation at recommended voltages, individual cell
voltages should be within +/- 0.05 Volts of the average cell voltage for
Liberty Series 1000 batteries.
21
When the voltages of individual cells are lower than normal, it is
possible to conclude that insufficient charging has occurred.
The following are possible causes of cell voltage variations:
• Panel voltmeter reading high - This results in a low float voltage.
Re-calibrate the panel voltmeter.
• Poor intercell/inter-unit or terminal connections - If any
connection is found to be higher than 20% of the initial installation
values, disassemble and clean contact surfaces and reassemble.
• A temperature variation of more than 5°F (2.8°C) between cells -
Warmer cells drop to a lower voltage, because they require more
float current to keep them fully charged. Avoid exposing batteries to
external heat sources, which can cause temperature imbalance.
3.4 Effects of temperature
A lead-acid battery is an electro chemical device. Heat accelerates
chemical activity; cold slows it down. Normal battery operating
temperature is 77°F (25°C). Higher than normal temperatures have
the following effects on a lead-acid battery:
• Increases capacity
• Shortens life
• Increases internal discharge or local action losses
• Lowers cell voltage for a given charge current
• Raises charging current for a given charge voltage
• Increases the rate of dry-out of electrolyte
Lower than normal temperatures have the opposite effect and reduce
capacity
. In general, at proper fl
oat voltage, a battery in a cool
location will last longer than one in a warm location.

Technologies.
If the oper
ating temper
ature is other than 77°F (25°C), it is recommend-
ed that the float voltage be changed as follows:
For temperatures other than 77°F (25°C), correct float voltage by 2

• Subtract 2 mV (0.002 Volts) per degree F (3.6 mV per degree C)
above 77°F (25°C)
Note: Temperature compensation will materially improve battery
service life when provided.
22
If continuous adjustment of the battery plant charger voltage relative
to ambient temperature is impractical, it is recommended the
appropriate fixed float voltage setting of Table 4 is used.
At temperatures below 77°F (25°C), battery capacity will be reduced
by approximately 0.5 percent per degree Fahrenheit.
Caution must be exercised when operating or storing batteries at low
temperature because of the possibility of electrolyte freezing.
Although the specific gravity of your fully charged battery may present
no freezing problem, the discharged specific gravity may. Refer to Part
1, Section 2, Table 1.
3.5 High ambient temperature
At higher than normal ambient temperature 77°F (25°C), gas that may
exceed the rate of recombination will be evolved internally. This gas
will vent to the atmosphere when internal pressure causes the relief
valve to open.
This is the equivalent of water loss that cannot be
replenished and therefore accelerates the rate of dry-out, resulting in
e-regulated battery
loss of capacity. The Liberty Series 1000 v

Valve-regulated lead acid batteries will incur a 50 percent

1. If the average ambient temperature changes over time more than 20°F (11.1°C) and no correction in float
voltage is made, permanent battery degradation will occur.
2. Temperature variations within the battery string of more than 5°F (2.8°C) can cause cells at the extremes
to be either over or under-charged, depending on where the float voltage has been set.

3.6 Cleaning cell covers
• Cell covers can be dusted with a clean cloth or clean dry paintbrush.
• Cell covers may also be cleaned with clear water and a small
amount of baking soda and dried after cleaning.
• If residual acid appears on the cover surfaces it may be neutralized
with a solution of one pound baking soda and one gallon of clear
water. Rinse with water following neutralization and air dry.
CAUTION
Never use solvents other than water to clean battery containers.
Many solvents will damage the plastic materials causing the
materials to crack or fail. A neutralizing solution of baking soda
and water may be used to clean acid spills.
Tap connections
3.7
Tap connections on the battery electr
ically unbalance the battery and
should never be used. Installing a tap will result either in partial or
complete discharge of the group of cells that are furnishing current to
the auxiliary load. In addition an o
untapped cells that will materially decrease their useful lif
vercharge is imposed on the
e. Tap connections most often inadvertently occur during initial installation when
installers ma
y be tempted to use a portion of the battery to po
equipment, par
ticularly prior to installation of electrical service. The
wer their
use of tap connections will void the warranty.
3.8 Putting batteries into storage
A batter
y on float charge provides maximum service life and, therefore,
should not be stored on open circuit unless it is unavoidable, but in
such cases only for a very limited time as discussed earlier in Part 1,
Section 2.
In such cases
, follow these recommendations before
de-energizing:
• Provide an equalize charge as described in Part 2, Section 1.3 and
Section 2.2.
• De-energize battery only after it is fully charged, typically 12 to 16
hours.
Disconnect batter
•

• Store the battery at approximately 77°F (25°C) in a horizontal
position. When returning the battery to service, restore all open
connections
, replace fuses, and treat as a new battery by providing
an initial charge.
24
3.9 Recor
d keeping
At a minimum, annual measurement of unit voltages should be taken
and recorded. On occasion, if a long discharge has been experienced,
completely recharge the battery and take a set of voltage readings,
recording them for future reference if the readings are satisfactory.
Provide remedial action or an equalize charge if necessary.
Do not
discharge a battery below the design final voltage. Remedial
action may be required if the battery was discharged below its final
design voltage.Very deep discharges can, without an immediate
recharge, completely deplete the electrolyte and cause hydration.
Note: Refer to sample form RS-1511 found in the Appendix to record
readings.

TROUBLE-SHOOTING, AVOIDING BATTERY DEGRADATION AND
RECOGNIZING PROBLEMS
SECTION 1 - HOW TO AVOID BATTERY DEGRADATION
1.1 General Information and Precautions
Properly maintained and charged, Liberty Series 1000batteries will
provide many years of trouble-free service. However, despite their
inherent dependability, failure to operate and maintain them correctly
can lead to damage, shortened service life or cause loss of service.
The following sections address some of the most frequently
encountered errors.
1.2 Float versus cycle life

contin
y batter
uous float service. They differ in their design from “cycling
batteries,” such as “star
continuously charged at a compar
ies are designed and constructed to provide long life in
ting” or “traction” types. Standby batteries are
atively low float voltage in parallel
with the load, ready to supply instantaneous dc power either directly to
the load or by way of interf
acing electronics, such as an un-interruptible
power supply (UPS) system. The name “stationary” implies the battery
is usually permanently placed in a given location and not transferred
from place to place in its ser
vice life.
Standby battery calendar life is affected by and may be reduced by
repeated cycling.
Depth of discharge, number of discharges
, rate of
discharge, and the interval between discharges are some of the
determining factors in battery life. Cycling should therefore be kept
to a minim
um.
To ensure that the battery will perform during power outages and other
emergencies

26
The user is expected to maintain complete records of all battery
testing and emergency discharges in order to comply with the
requirements of the warranty.
CAUTION
RECHARGE BATTERIES AS SOON AS POSSIBLE AFTER AN
EMERGENCY DISCHARGE. Failure to recharge batteries
immediately after emergency discharge may lead to sulfation
or, in the case of deep discharge, to complete battery failure
due to hydration. If recharging at equalize voltage is
impractical, recharge at float voltage.
1.3 Low float voltage and sulfation
Either because of incorrect charger voltage adjustment or excessive
intermittent or static loads paralleling the charging source or low
operating temperature, a battery may not receive adequate charge. In
some cases, the charger may even be turned off, erroneously or by
choice. The net result is a battery left in a partially discharged
condition. The first observable signs may be erratic cell voltages.

le to the obser
ver, the plates will become sulfated.

1.4 Hydration
A battery that has been severely over-discharged and left in a
discharged condition without immediate recharge is subject to damage
wn as hydration. This is a phenomenon in which the electrolyte

specific gravity has been reduced to a value so low it permits the lead
components to dissolve into the electrolyte.

ators placed
between the positive and negative plates to provide electrical
insulation. Very often, the effect of these short circuits goes unnoticed

e
or a slight increase in charging current. As the reaction
continues, however, short circuits become so extensive it is almost
impossible to keep the cells charged. Finally, the cells experience total
ailure.
f
1.5 Open circuit - late installations
As soon as a battery is disconnected from a charger, local action
(discharge) begins. This is caused by inherent internal losses within
the cell.
In the case of Liberty Series 1000 cells, a self-discharge is
expected to occur at a rate of “up to 3.0 percent” of full charge per
month at 77°F (25°C). Therefore, if cells remain, for whatever reason,
on open circuit (with no charge supplied) for prolonged periods of time,
27
the affected cells may become sulfated and require corrective action.
1.6 Parallel battery strings
When strings of batteries of equal voltage are connected in parallel,
the overall capacity is equal to the sum of the capacities of the
individual strings. When paralleling valve-regulated batteries is
necessary, the external circuit resistance must be matched for each
battery. A large variation between battery string resistance can result
in unbalanced discharge (i.e., excessive discharge currents in some
batteries and less discharge in others). As a consequence, cell
failures in one battery string and the subsequent loss of performance
capacities of that string will result in higher loads in the lower resistance interconnections of some parallel strings that may exceed
the ratings of the battery interconnections and/or cables. C&D
Technologies recommends paralleling strings to obtain higher capacity.
Paralleling cells is not recommended due to potential safety and
maintenance problems.
1.7 High temperature operation
Operating a batter
y at temperatures exceeding 77°F (25°C) will reduce
battery service life. Elevated temperatures accelerate the electro
chemical reaction within lead acid batteries.
