SECTION 1 - GENERAL INFORMATION
1.0 RELAY GEL VRLA BATTERIES
In normal use, the battery will not release hydrogen gas or acid mist, and will not leak
acid. However, there is the possibility that under abnormal operating
conditions hydrogen gassing, acid mist, and leaking electrolyte could occur. Thus
®
GNB
Industrial Power recommends that Section 2 of these instructions entitled
“SAFETY PRECAUTIONS” be reviewed thoroughly and strictly followed when working
with batteries.
SECTION 2 - SAFETY PRECAUTIONS
2.0 SAFETY ALERT
The safety alert symbol at left appears
throughout this manual. Where the symbol
appears, obey the safety message to avoid
personal injury.
CAUTION
Before proceeding with the unpacking, handling, installation and
operation of this sealed lead-acid storage battery, the following
general information should be reviewed together with the
recommended safety precautions.
DANGER
2.1 SULFURIC ACID BURNS
SULFURIC ACID BURNS
Batteries contain sulfuric acid which can cause burns and other serious injury. In the
event of contact with sulfuric acid, flush immediately and thoroughly with water. Secure
medical attention immediately.
When working with batteries, wear rubber apron and rubber gloves. Wear safety
goggles or other eye protection. These will help to prevent injury if contact is made with
the acid.
DANGER
2.2 EXPLOSIVE GASES
EXPLOSIVE GASES
Batteries could generate explosive gases, which when released, can explode and
cause blindness and other serious injury. If the safety vent opens while the explosive
gases are being generated (e.g., in the event of a charger malfunction), these explosive
gases will be released.
Keep sparks, flame and smoking materials away from the battery area and
explosive gases.
DANGER
ELECTRICAL SHOCK
2.3 ELECTRICAL SHOCK AND BURNS
AND BURNS
All installation tools should be adequately insulated to minimize the possibility of shorting across connections.
1
Never lay tools or other metallic objects on the batteries as shorting, explosions and
personal injury may result.
Multi-cell systems attain high voltages; therefore, extreme caution must be exercised
during installation of a battery system to prevent serious electrical burns or shock.
Loose or dirty connectors/connections can cause battery fires. Keep all connectors/
connections clean and torques at proper values. Keep outside of batteries clean and
dry. Neutralize any acid corrosion with a cloth moistened with a solution of baking soda
and water, then wipe off all traces of soda.
Do not move or shift racks/cabinets once installed without first disconnecting load to
rack/cabinet and all inter-rack/cabinet connections. Consult wiring diagrams for location
of these connections.
Do not lift cells by terminal posts. Do not tamper with post seals, protective covers,
pressure relief vents or other battery components.
Disconnect the AC and DC circuits before working on batteries or charging equipment.
Assure that personnel understand the risk of working with batteries, and are prepared
and equipped to take the necessary safety precautions. These installation and
operating instructions should be understood and followed. Assure that you have the
necessary equipment for the work, including insulated tools, rubber gloves, rubber
aprons, safety goggles and face protection.
CAUTION !
If the foregoing precautions are not fully understood, clarification should
be obtained from your nearest GNB representative. Local conditions may
introduce situations not covered by GNB Safety precautions. If so, contact
the nearest GNB representative for guidance with your particular safety
problem before proceeding to install or service these batteries. Refer to
applicable federal, state and local regulations as well as industry
standards.
2.4 IMPORTANT MESSAGE
The symbol at left indicates an important
message. If not followed, damage to and/or
impaired performance of the battery may
result.
SECTION 3 - RECEIPT OF SHIPMENT
3.0 DELIVERY INSPECTION
Immediately upon delivery, examine for possible damage caused in transit. Damaged
packing material could indicate rough handling. Make a descriptive notation on the
delivery receipt before signing. If cell or unit damage is found, request an inspection by
the carrier and file a damage claim immediately. Any battery with post or seal damage
should be replaced.
2
3.1 CONCEALED DAMAGE
Within 15 days of receipt, examine all batteries for concealed damage. If damage is noted,
immediately request an inspection by the carrier and file a concealed damage claim. Any
delay in notifying carrier may result in loss of right to reimbursement for damages.
SECTION 4 - STORAGE PRIOR TO INSTALLATION
4.0 STORAGE LOCATION
If the battery is not to be installed at the time of receipt, it is recommended that it be
stored indoors in a cool [25°C (77°F)], clean, dry location. Do not stack pallets or
possible battery damage may occur.
4.1 STORAGE INTERVAL
The storage intervals between the date of shipment and the date of initial charge
should not exceed six (6) months. The battery should be given its initial charge (refer to
Section 8) before the end of the above stated storage interval. Storage at elevated
temperatures will result in accelerated rates of self discharge. A general rule of thumb
is that for every 10°C (18°F) increase above 25°C (77°F) the time interval for initial
charge should be halved. For example, if a battery was stored at 35°C (95°F) the initial
charge time interval would be 3 months. If the battery was stored at 30°C (86°F) the
initial charge time interval would be 4.5 months. Storage beyond these periods without
proper charge can result in excessive sulfation of the plates which is detrimental to
battery performance and life.
SECTION 5 - GENERAL INSTALLATION CONSIDERATIONS
Prior to starting the installation of the RELAY GEL battery system, a review of this section is strongly recommended.
5.0 BATTERY LOCATION
It is recommended that the battery be installed in a clean, cool, dry location. Floors
should be reasonably level and able to support the battery weight. A location having an
ambient temperature of 25°C (77°F) will result in optimum battery life and performance.
Temperatures below 18°C (65°F) reduce battery efficiency. Temperatures above 27°C
(80°F) will result in a reduction of battery life. Continuous operation above 50°C (122°F)
is not recommended.
A designated aisle space should be provided to permit initial installation and future
service or surveillance of the batteries.
3
5.1 BATTERY ORIENTATION
YES
N
ONO
The RELAY GEL battery can only be installed in a vertical orientation with the posts
pointing up (per Figure 1). This battery may not be placed on its sides. Contact your
local GNB Industrial Power representative if you require the battery to be placed in a
different orientation.
Figure 1
5.2 VENTILATION
The RELAY GEL battery is a valve regulated battery which under normal recommended
charging in a stationary application does not vent any gases.
However, should the battery be subjected to excessive overcharge, hydrogen and
oxygen can be vented to the atmosphere. Therefore, the battery should NEVER BE
INSTALLED IN AN AIRTIGHT ENCLOSURE. Sufficient precautions must be taken to
prevent excessive overcharge. Normal ventilation sufficient for human occupation will be
adequate to avoid hazardous conditions.
Tests have confirmed that more than 99% of gases generated are recombined within
the battery. Under normal operating conditions, no special ventilation and/or battery
room is required.
RELAY GEL batteries can be installed in close proximity to electronic equipment only
when the heat generated by this equipment is removed by ventilation.
5.3 TEMPERATURE VARIATIONS
Sources of heat or cooling directed on portions of the battery can cause temperature
variations within the strings resulting in cell voltage differences and eventual
compromise of battery performance. Heat sources, such as heaters, sunlight or
associated equipment, can cause such temperature variations. Similarly, air
conditioning or outside air vents should not directly influence portions of battery string
temperatures. Every effort should be made to keep temperature variations within
3°C (5°F).
5.4 FLOOR LOADING
The area where the battery system is to be installed should have the capability to
support the weight of the battery as well as any auxiliary equipment. The total battery
weight will depend on the battery size, number of batteries, as well as the configuration
involved. Prior to installation, a determination should be made that the floor integrity is
adequate to accommodate the battery system.
5.5 FLOOR ANCHORING
Where seismic conditions are anticipated, floor anchoring should be provided. Such
anchoring is the responsibility of the user.
4
5.6 OPEN CIRCUIT VOLTAGE CHECK
The voltage of each unit should be checked to insure the voltage is at least 12.6 volts. If
any unit has a voltage lower than 12.6 volts, follow the initial charge procedures shown in
Section 8.
SECTION 6 - RACK SYSTEM - INSTALLATION
6.0 PLACEMENT OF UNITS ON RACK
When installing units on a rack, start on the lower tier for stability and safety reasons.
Place units on the rack so that the positive (+) of one unit is connected to the negative (-)
of the next unit. Standard spacing is 12mm (1/2 inch) minimum between units.
Determine the number of units to be placed on each row. If a row of units does not fill the
entire rack length, fill the remaining space with foam cell spacers in seismic
installations.
SECTION 7 - ELECTRICAL INSTALLATION CONSIDERATIONS
7.0 CONNECTING CABLES: BATTERY SYSTEM TO OPERATING EQUIPMENT
Battery performance is based on the output at the battery terminals. Therefore, the
shortest electrical connections between the battery system and the operating equipment
should be used for maximum total system performance. A terminal plate kit should be
utilized when connecting multiple cables to a battery terminal post.
DO NOT SELECT CABLE SIZE BASED ON CURRENT CARRYING CAPACITY ONLY.
Cable size selection should provide the lowest voltage drop possible between the
battery system and operating equipment. Excessive voltage drop will reduce the desired
support time of the battery system.
7.1 PARALLELING
Where it is necessary to connect battery systems in parallel to obtain sufficient capacity,
cable connections from the bus/load to each of the parallel strings is preferred rather than
inter-string paralleling. The maximum number of parallel strings recommended by GNB in
high rate applications is 4.
Cables should be sized to minimize voltage drop, and for proper current carrying
capability. They should be as short as possible. However, the lengths of cables for all of
the systems being paralleled to the load should be equal in length and size to provide
proper load sharing on discharge plus satisfactory recharge with the same float voltage
per string. Care should be taken to ensure the overall resistance of the connection
between batteries and equipment bus are consistent between strings.
7.2 CONNECTION PREPARATION
Gently clean contact surfaces only by using a brass suede brush, 3M Scotch Brite
®
Green scouring pad, or #00 grade steel wool being careful not to remove lead plating
from inter-unit connectors. Immediately after contact areas are cleaned, apply a thin coat-
®
ing of NO-OX-ID
“A” grease to these surfaces only.
5
7.3 CONNECTION TORQUEING
After cleaning contact surfaces, install all connectors hand tight to allow for final alignment
of units. Once final alignment is made, all connections should be torqued to the value
shown on the battery label (typically this value is 11.3 N-M or 100 inch-lb.)
Complete connection of units by installing the inter-tier cables and terminal plates
(when required).
Caution
, do not make connections to the load at this time.
7.4 CONNECTIONS
Battery terminal and intercell connections should be corrosion free and tight for
trouble-free operation. Periodically, these connections should be inspected to ensure
cleanliness and integrity.
CAUTION
DO NOT WORK ON CONNECTIONS WITH BATTERY
CONNECTED TO CHARGER OR LOAD
If corrosion is present, disconnect the connector from the terminal. Gently clean the
affected area using a brass suede brush, 3M Scotch Brite
®
Green scouring pad, or #00
steel wool being careful not to remove lead plating from interunit connectors. Apply a
thin coat of NO-OX-ID®“A” grease to the cleaned contact surfaces. Re-install connectors and retorque connections.
All terminals and intercell connections should be retorqued at least once every year.
Maintaining electrical integrity of connectors is important, since poor connections will
result in reduced battery output and, in extreme cases, may add to heating and could
result in melted battery posts, circuit interruptions, or battery fires.
7.5 BATTERY TO CHARGER CONNECTION
The positive (+) terminal of the battery should be connected to the positive (+) terminal
of the charger and the negative (-) terminal of the battery to the negative (-) terminal of
the charger. A terminal plate kit should be utilized when connecting multiple cables to a
battery terminal post.
6
7.6 CONNECTION RESISTANCE
Electrical integrity of connections can be objectively established by measuring the
resistance of each connection. These resistances are typically in the microhm range.
Meters are available which determine connection resistance in microhms. Be sure that
the probes are touching only the posts to insure that the contact resistance of connector
to post is included in the reading.
Resistance measurements or microhm measurements should be taken at the time of
installation and annually thereafter. Initial measurements at installation become the
bench mark values and should be recorded for future monitoring of electrical integrity.
It is important that the bench mark value for all similar connections be no greater than
10% or 5 microhms, whichever value is greater over the average. If any connection resistance exceeds the average by more than 10% or 5 microhms, whichever is greater, the
connection should be remade so that an acceptable bench mark value is established.
Bench mark values for connection resistances should also be established for terminal
plates, where used, as well as cable connections. Bench mark values should preferably
be established upon installation.
All bench mark values should be recorded. Annually, all connection resistances should
be remeasured. Any connection which has a resistance value 20% above its bench
mark value should be corrected.
SECTION 8 - INITIAL CHARGE
8.0 CONSTANT VOLTAGE METHOD
Batteries lose some charge during shipment as well as during the period prior to
installation. A battery should be given its initial charge as soon as possible after receipt.
Constant voltage is the only charging method allowed. Most modern chargers are of the
constant voltage type.
Determine the maximum voltage that may be applied to the system equipment. This
voltage, divided by the number of cells connected in series, will establish the maximum
volts per cell (VPC) that may be used.
Table A lists recommended voltages and charge time for the initial charge. Select the
highest voltage the system allows to perform the initial charge in the shortest time
period. Do not exceed the highest voltage listed for a given temperature. Do not exceed
the maximum current(s) shown in Section 9.3.

NOTE: Time periods listed in Table A are for temperatures from 21°C (70°F) to 32°C
(90°F); for temperatures 13°C (55°F) to 20.5°C (69°F), double the number of hours
For temperatures other than 25°C (77°F) the following formula can be used to
determine the recommended initial charge voltage per cell (VPC):
V corrected = V25°C - [(T actual - 25°C) x (0.003 V/°C)] or
V corrected = V77°F - [(T actual - 77°F) x (0.0017 V/°F)]
Example at 29.4°C (85°F) and at 24 hr. initial charge
V corrected = 2.40 - (29.4-25) (0.003)
= 2.40 - 0.0132
= 2.387 VPC
Raise the voltage to the maximum value permitted by the system equipment, but do
not exceed the maximum voltage listed for a given temperature. When charging
current has tapered and stabilized (no further reduction for three hours), charge
for the hours shown in Table A or until the lowest unit voltage ceases to rise. Correct
charge time for the temperature at the time of stabilization. To determine the lowest voltage unit, monitoring should be performed during the final 10% of the charge time.
SECTION 9 - OPERATION
.
9.0 FLOAT CHARGE
In this type of operation, the battery is connected in parallel with a constant voltage
charger and the critical load circuits. The charger should be capable of maintaining the
required constant voltage at the battery terminals and also supply the normal load
where applicable. This sustains the battery in a fully charged condition and also makes
it available to assume the emergency power requirements in the event of an AC power
interruption or charger failure.
9.1 FLOAT VOLTAGES
Following is the float voltage range recommended for the RELAY GEL Battery System.
Select the “volts per cell” (VPC) value within the range listed that will result in the battery series string having an average volts per cell equal to that value.
RECOMMENDED FLOAT VOLTAGES: 77°F (25°C) = 2.25 VPC to 2.30 VPC
MAXIMUM CURRENT: 20A / 100 AH (20 hr rating to 1.75V@25C)
For temperatures other than 77°F (25°C) the following formula can be used to
determine the recommended float charge voltage per cell:
V corrected = V25°C - [(T actual - 25°C) x (0.0055 V/°C)] or
V corrected = V77°F - [(T actual - 77°F) x (0.003 V/°F)]
8
Minimum float voltage (temperature corrected) is 2.21 VPC. Temperature correction
does not apply below this value.
Maximum float voltage (temperature corrected) is 2.40 VPC. Temperature correction
does not apply above this value.
Example
Modern constant voltage output charging equipment is recommended for the float
charge method of operation for the batteries. This type of charger, properly adjusted to
the recommended float voltages and following recommended surveillance procedures,
will assist in obtaining consistent serviceability and optimum life.
After the battery has been given its initial charge (refer to Section 8), the charger should
be adjusted to provide the recommended float voltages at the BATTERY TERMINALS.
Do not use float voltages higher or lower than those recommended. Reduced capacity
or loss of battery life will result.
9.2 VOLTMETER CALIBRATION
Panel and portable voltmeters used to indicate battery float voltages should be
accurate at the operating voltage value. The same holds true for portable meters used
to measure individual cell/battery voltages. These meters should be checked against a
standard every six months and calibrated when necessary.
At 18.3°C (65°F)
V corrected = 2.27 - (18.3-25) (0.0055)
= 2.27 + 0.037
= 2.307 VPC
9.3 RECHARGE
All batteries should be recharged as soon as possible following a discharge with
constant voltage chargers. Recharge time should not exceed recommendations given in
Section 8.0, Table A. However, to recharge in the shortest period of time, raise
the charger output voltage to the highest value that the connected system will permit.
Do not exceed 2.40 VPC. Maximum recharge current should be limited to 20A / 100 AH
(20 hr rating to 1.75V@25C). The charger used should incorporate a current limit feature. The maximum recommended charge current for the battery is as shown below:
Model
Relay Gel R12VU1 6.0
Relay Gel R12V22 10.0
Relay Gel R12V24 14.3
Relay Gel R12V27 17.2

9.4 DETERMINING STATE OF CHARGE
If the normal connected load is constant (no emergency load connected), the following
method can be used to determine the approximate state of charge of the battery. This
state of charge can be identified to some degree by the amount of charging current
going to the battery. When charging, the current read at the charger ammeter will be a
combination of the load current plus the current necessary to charge the battery. A
condition where the current remains constant for a period of three consecutive hours
would reflect approximately 90 to 95% state of charge.
If the normal connected load is variable (e.g., telecommunications), the following
method can be used to check the state of charge of the battery. With the battery on
float and stabilized, measure the voltage across a pilot unit. If the voltage is stable for
three consecutive hours, the battery is considered 100% charged.
9.5 EFFECTS OF TEMPERATURE
Temperature has a direct effect on the life of a battery. The design life of the battery is
based on an average annual temperature of 25°C (77°F). As the temperature increases
above 25°C (77°F), the life of the battery decreases. The chart below shows the effects
of temperature.

35°C (95°F)
40°C (104°F)
45°C (113°F)
50°C (122°F)
For example: If a battery has a design life of 10 years at 25°C (77°F), but the actual
annual average battery temperature is 35°C (95°F), the projected life of the battery is
calculated to be only 5 years [10 years - (10 years X 0.50) = 5 years].
Temperature records shall be maintained by the user in accordance with the
maintenance schedule published in this manual. The battery temperature shall not be
allowed to exceed the maximum temperature shown above. It is important to maintain
the battery temperature as close to 25°C (77°F) to achieve the optimum service life
from your battery.

9.6 EFFECTS OF FLOAT VOLTAGE
Float voltage also has a direct effect on the service life of your battery. A float voltage
above the recommended limits reduces service life. The chart below shows the effects
of float voltage (temperature corrected, see section 9.1) on battery life.
Temperature corrected 25°C (77°F)

For example: A battery has a design life of 10 years, but the actual annual average float
voltage is 2.33 volts per cell. The projected life of the battery is calculated to be 5 years
[10 years - (10 X 0.50) = 5 years].
Voltage records shall be maintained by the user in accordance with the maintenance
schedule published in this manual. To obtain the optimum service life from the battery,
it is important to make sure the battery’s float voltage is within the recommended range.
SECTION 10 - EQUALIZATION
10.0 EQUALIZING CHARGE
Maximum
Percent
Reduction
In Battery life

Under normal operating conditions an equalizing charge is not required. An equalizing
charge is a special charge given to a battery when non-uniformity in voltage has
developed between units. It is given to restore all units to a fully charged condition.
Use a charging voltage higher than the normal float voltage and for a specified number
of hours, as determined by the voltage used.
The recharge parameters of Section 9.3 apply for this section also.
Non-uniformity of units may result from low float voltage due to improper adjustment of
the charger or a panel voltmeter which reads an incorrect (higher) output voltage. Also,
variations in unit temperatures greater than 3°C (5°F) in the series string at a given
time, due to environmental conditions or battery arrangement, can cause low voltage
batteries.
10.1 EQUALIZING FREQUENCY
An equalize charge should be given when either of the following conditions exist.
A. The float voltage of the pilot unit (or any unit for quarterly readings ) is less than
2.21 VPC.
B. A recharge of the battery is required in a minimum time following an emergency
discharge.
11
SECTION 11 - MAINTENANCE SCHEDULE
A pilot unit is selected in the series string to reflect the general condition of all units in
the battery. The pilot unit should be the battery with the lowest voltage in the string
following the initial charge. By measuring the pilot unit voltage, it serves as an indicator
of battery condition between scheduled overall individual unit readings.
A complete recorded history of the battery operation is most desirable and helpful in
obtaining satisfactory performance. Good records will also show when corrective action
may be required to eliminate possible charging, maintenance or environmental
problems.
The following data should be read and permanently recorded for review by supervisory
personnel:
A. Upon completion of the initial charge and with the battery on float charge at the
proper voltage for one week, read and record the following:
1. Individual battery voltages
2. Battery string terminal voltages
3. Ambient temperature
B. Every 12 months, a complete set of readings as specified in Paragraph A above must
be done and all individual connections retorqued.
C. Whenever the battery is given an equalizing charge, an additional set of readings
should be taken and recorded as specified in Paragraph A above.
The suggested frequency of record taking is the absolute minimum to protect warranty.
For system protection and to suit local conditions or requirements, more frequent
readings (quarterly) are desirable.

Tap connections should not be used on a battery. This can reduce battery life.
SECTION 13 - TEMPORARY NON-USE
An installed battery that is expected to stand idle for over 6 months should be treated
as follows:
A. Give the battery an equalizing charge. Following the equalizing charge, open the
connections at the battery terminals to remove charger and load from the battery.
B. Every six months, temporarily connect battery to charger and give an equalizing
charge.
C. To return the battery to normal service, retorque all connections per Section 7.3 and
then re-connect the battery to the charger and return the battery to float operation.
D. If the battery is standing at an elevated temperature, corrections to the time period
to equalize charge should be corrected per Section 4.1.
SECTION 14 - UNIT CLEANING
Periodically clean unit covers to remove accumulated dust. If any unit or parts appear to
be damp with electrolyte or show signs of corrosion, clean with a solution of baking
soda and water or isopropyl alcohol, and re-examine within 30 days to determine if the
condition re-occurs. If so, contact your local GNB representative.
Do not clean plastic parts with any solvents, detergents, mineral
CAUTION
spirits, or spray-type cleaners other than those mentioned here as
these can cause crazing or cracking of the plastic materials.
