CAUTION! Before proceeding with the unpacking,
handling, installation and operation of a lead-acid storage
battery, the following general information should be reviewed
together with the recommended safety precautions.
A lead-acid battery is an electrochemical device that contains
electrolyte. The electrolyte is corrosive and can cause injury.
Lead-acid batteries, when installed, are capable of high
voltage that can cause electrical shocks to personnel.
All lead-acid batteries in the course of normal operation
generate gases that could be explosive.
SECTION 1
1.0 SAFETY
1.1 Follow your company’s safety instructions when working
with or near industrial lead-acid batteries. Thoroughly
familiarize yourself with industry and government guidelines
for charging, handling, and maintaining industrial batteries.
1.2 Assign battery and charger care to properly trained
personnel. The battery contains sulfuric acid. Avoid sulfuric
acid contact with skin, eyes, or clothing. Wear a rubber
apron, gloves, boots, and goggles or face shield when
handling, checking, filling, or charging batteries.
1.3 Keep water readily available for flushing spilled electrolyte
from eyes or skin. Obtain medical attention immediately.
1.4 Batteries produce hydrogen. Keep open flames away.
Do not check electrolyte level with a cigarette lighter or
match. Use a flashlight or permanent lights only. Do not
smoke or create sparks when working on batteries.
1.5 Platform lifts of adequate capacity to handle cell weights
and dimensions may be used provided they are stable and
capable of reaching needed heights and used on smooth
and level floor conditions.
1.6 Never lay metal tools, such as wrenches or other material
on top of batteries.
1.7 Insulate tool handles to protect against shorting.
1.8 Make sure that all battery connections are properly
prepared and tightened to prevent possible injury to personnel
or failure of system.
1.9 If acid is spilled on the floor, apply a strong neutralizer,
like baking soda. Check local regulations regarding disposal
of neutralized waste.
SECTION 2
2.0 RECEIVING BATTERIES
2.1 Immediately upon receipt of shipment, examine for
possible damage caused in transit. Damaged packing
material or staining from leaking electrolyte would indicate
rough handling. If such conditions are found, make notation
on delivery receipt before signing. If battery damage is found,
request an inspection by the carrier and file a damage claim.
Also notify your GNB®Industrial Power representative.
2.2 Shortly after receipt (within 15 days), examine all batteries
for concealed damage. Pay particular attention to packing
materials exhibiting damage or electrolyte staining. Perform
examination prior to installation and disposal of packing
materials. Examine cells for container damage, misaligned
elements, broken plates, or any other visible damage.
SECTION 3
3.0. STORAGE
3.1. If the battery is not to be installed at the time of receipt,
it is recommended that it be stored indoors in a cool [16°C
(60°F) to 32°C (90°F)], clean, and dry location. Do not top
load pallets as possible battery damage may occur.
3.2. Prior to planned installation of the battery, the accessory
parts should be opened and checked against shipping
invoice (or battery system drawings) for completeness.
Checking parts before storage will eliminate potential delays
during installation.
3.3. The storage interval from date of shipment to the date of
installation/initial charge should not exceed six (6) months.
(Assumes 77°F/25°C average storage temperature. Assume
three months maximum storage time for 90°F/32°C average
temperatures.) Storage beyond the stated period can result
in sulfated plates, which can be detrimental to battery life and
performance. Failure to store the battery in accordance with
the above recommendations may void the warranty.
SECTION 4
4.0 BATTERY ASSEMBLY
AND INSTALLATION
4.1 SITE
It is recommended that the battery be installed indoors in a
clean and dry location. The battery should be shielded from
direct sunlight, heating units or steam pipes as they can
cause temperature gradients in the electrolyte and negatively
impact battery performance. The floor should be level and
capable of supporting the weight of the batteries (and rack).
4.2 VENTILATION
All lead-acid batteries in the course of normal operation
generate gases that could be explosive. Ventilation should
be provided in the battery room to prevent hydrogen gas
from exceeding a concentration of 1%. Concentrations
above this value can result in an explosive mixture that can
be ignited by sparks from adjacent electrical equipment. All
air moved by ventilation should be exhausted to the outside
and not be allowed to re-circulate into other confined areas.
2

4.3 TEMPERATURE
A battery location having an ambient temperature of 25°C
(77°F) will result in optimum battery life. Batteries operated
above this temperature will suffer reduced life, while batteries
operated below this temperature may exhibit suppressed
capacity. Though brief temperature excursions between
0°C (32°F) and 40°C (104°F) can be tolerated, the normal
operating temperature is between 16°C (60°F) and 32°C
(90°F).
4.4 ELECTROLYTE LEVEL
During normal operation, the electrolyte level should be
between the high and low marks on the battery container.
Upon receipt of the battery, the electrolyte level may be a
bit lower than this mark; after charging, it may be higher.
The reason is that gas bubbles formed during charge will
adhere to the battery plates, displacing and raising the
electrolyte level. Do not attempt to adjust the electrolyte
either immediately upon receipt or immediately after the
initial charge.
4.5 CELL POSITIONING
By now, it is assumed that the rack has been assembled.
Determine the desired position of the positive and negative
terminals. Measure and mark the center of the rack.
Determine the number of battery blocks that will fit on a step/
tier of the rack. If that number is odd, position the centerline
of the first battery block on the centerline of the rack step/tier.
If the number is even, position the end of battery block on
the centerline of the rack step/tier. Work from the center out,
positioning the positive terminal next to the negative terminal
of the adjacent cell.
If a lubricant is needed to facilitate battery
positioning, use only Dow Corning 111.
Lubricants that contain solvents may damage
the battery containers and void warranty.
4.6 FLASH ARRESTORS
After the batteries have been positioned on the rack (but
before the inter-unit and inter-tier connections have been
made), replace the shipping caps with the provided flame/
flash arrestors.
4.7 CONTACT SURFACES
Gently clean the contact surfaces of the battery terminal
posts using a 3M Scotch Brite or similar scouring pad. Coat
the electrical contact surfaces lightly with provided No-Ox
grease.
4.8 ELECTRICAL CONNECTIONS
Install and torque the provided M8 stainless steel hardware
and torque the cell connector (or terminal plate) to the post.
Target connection torque is 100 - 110 inch-lbs. (11.3-12.0
N-m). Re-torque the stainless steel hardware 24 hours after
the initial tightening to account for relaxation of the lead-
hardware connection.
Electrical connections must be clean to minimize voltage drop
and prevent connector heating. If corrosion is observed, DO
NOT RE-TORQUE! The connection must be disassembled,
cleaned, neutralized, and then re-torqued.
Install the inter-tier cables as necessary. Do not connect
cables directly to the battery post. Utilize the terminal
plates provided for main terminal and inter-tier connections.
Re-check to be certain that the batteries are connected
positive terminal to negative terminal throughout the string.
Before connecting the battery string to the charger/load,
measure the total voltage at the battery terminals. The
voltage should be equal to the number of cells times the
voltage of one cell. For example, 60 cells times 2.09 volts
per cell = 125.40 volts (1.250 SG) or 60 cells times 2.05 volts
per cell = 123.0 volts (1.215 SG).
4.9 CONNECTION RESISTANCE
Connection resistance or micro-ohm (µΩ) measurements
should be taken at the time of installation and annually
thereafter. Initial measurements at installation become
benchmark values. Future values are compared to
this benchmark as an indication of connection integrity.
Re-torque of connections should be performed annually or
when connection resistance increases to more than 20%
over the benchmark value.
4.10 Labels and Markings
Numerals and polarity markings should not be applied
until after the cells have been installed on the rack. It is
recommended that they be applied to jar surfaces only, and
not to cell covers or rack rails.
2. Clean the plastic jar surface, in the area where the
numeral is to be located, by using a cloth dampened with a
washing soda solution. Immediately dry the area using a soft
dry cloth to remove residual washing soda.
CAUTION!! Do not use any solvent type materials as they
may cause damage to the plastic jar material.
3. It is a general practice to designate the positive terminal
cell as #1 with succeeding cells in series in ascending order.
4.11 INITIAL CHARGE
The first charge that the battery receives after shipping,
storage and installation is very important as it may affect the
life of the battery. Determine the maximum charge voltage
output that the charge system can provide and charge the
battery in the least amount of time possible according to
Table A. This maximum voltage divided by the number of
cells connected in series is the maximum charge voltage per
cell (VPC). If long periods of continuous charging are not
possible at the installation, (e.g. photovoltaic applications)
the battery should be charged where such capability exists.
The recommended times given in TABLE A are considered
minimum. Charge the cells until the charge current tapers
and stabilizes for 3 hours. Then, charge the battery for the
times and voltages given in TABLE A.
3

SECTION 5
5.0 EQUALIZING CHARGE
An equalizing charge is a special charge given to the battery
in operation when one of the following conditions exist:
• The specific gravity of cells is more than 10 points lower
than its full charge value.
• The on-charge voltage of any cell is more than 0.05 VPC
below the average.
• It is desired to recharge the battery in the least amount of
time possible.
• It has been a year since the last equalizing charge.
5.1. Equalize the cells until the charge current tapers and
stabilizes for 3 hours, then charge according to the values
given in TABLE B.
TABLE A – Initial Charge Voltage
per Cell (VPC) and Time after Current
Stabilization for 1.215 and 1.250 SG TCXG
TABLE B – Equalizing Voltage
per Cell (VPC) and Time after Current
Stabilization for 1.215 and 1.250 SG TCXG
NOTE: Time Periods listed in tables A and B are for
cell temperatures from 70°F (21°C) to 90°F (32°C). For
temperatures 55°F (13°C) to 69°F (20.5°C) double the
number of hours. For temperatures 40°F (4°C) to 54°F
(12°C) use four times the number of hours listed.
SECTION 6
6.0 SPECIFIC GRAVITY
6.1 The Specific Gravity (SG) of a fully charged battery is
1.215 ± 0.010 or 1.250 ± 0.010. Specific gravity is used
to determine the cell’s state of charge (SOC). The value
decreases as the battery is discharged and increases as the
battery is recharged.
6.2 Specific gravity is expressed to the third decimal place,
e.g.1.250, and is measured by a hydrometer float enclosed
in a glass barrel/rubber bulb syringe. Holding the hydrometer
vertically, draw sufficient electrolyte into the barrel. The
reading should be taken when a) no hand pressure is being
exerted on the bulb and b) the float is not touching the side
of the hydrometer glass. The gravity is then read on the
hydrometer scale at the flat surface of the electrolyte. (See
Figure 1).
6.3 When making specific gravity readings, corrections must
be made for variations in the temperature of the electrolyte.
For each 1.67°C (3°F) difference in temperature of the
electrolyte above 25°C (77°F), add one point (0.001) to the
hydrometer reading. Conversely, for each 1.67°C (3°F)
difference below 25°C (77°F), subtract one point (0.001)
from the observed hydrometer reading.
Example:
Reading
Hydrometer Cell Corrected to
Reading Temperature Correction 25°C (77°F)
1.253 20°C (68°F) -.003 1.250
1.257 30°C (86°F) +.003 1.260
1.254 35°C (95°F) +.006 1.260

SECTION 7
7.0 OPERATION
7.1 Operating the battery outside the specified float
voltage range can be detrimental to battery life and
performance. Failure to operate the battery within the
specified float range may void the warranty.
TABLE C – Recommended Float
Voltages @ 25°C (77°F)
7.2 Ideally, 108% to 115% of the ampere-hours removed
during discharge from a battery should be restored upon
recharge to insure 100% state of charge.
SECTION 8
8.0 CELL VOLTAGE VARIATION
8.1 Temperature. Cell voltage non-uniformity can be caused
by cell temperature variation throughout the string. To
properly analyze battery voltage uniformity within the string,
voltage readings should be corrected for (battery electrolyte)
temperature. The battery temperature correction factor
for voltage equals 0.003 volts for each degree Fahrenheit
(0.0055 V/°C) using a base 77°F (25°C).
The correction factor is added to the measured battery voltage
above 77°F(25°C). The correction factor is subtracted from
the measured battery voltage below 77°F(25°C). Operate
the the battery such that its corrected voltage is in the range
given for its specific gravity.
Example:
Cell Voltage Corrected
Voltage Cell Correction Cell Voltage
Readings Temperature Factor @ 25°C (77°F)
2.300 20°C (68°F) -0.027 2.273
2.300 30°C (86°F) 0.027 2.327
2.300 35°C (95°F) 0.054 2.354
8.2 Damp Covers. Cell Voltage variation can occur when the
battery covers become wet or damp. Electrolyte spilled from
specific gravity measurements can cause parasitic current
paths across the tops of cell covers. These paths reduce
the quantity of current going through the battery and result
in undercharging and voltage variation. Eliminate the paths
by cleaning the battery cover with a solution of baking soda
and water (1 pound soda per gallon of water). Apply a cloth
dampened with the solution and neutralize acid until fizzing
stops, then wipe area with a clean cloth dampened only with
water to remove the soda. Do not get any of the baking soda
solution inside the battery.
SECTION 9
9.0 WATER ADDITIONS
9.1 The water in the electrolyte of a battery is lost by
evaporation and through hydrolysis into its component
hydrogen and oxygen gases. Both the water vapor and
electrolytic gases are liberated to the environment through
the cell vent. Periodically it will be necessary to add water
to the battery. When necessary to add water to the battery,
do so before the battery is equalized. This will allow added
water and electrolyte to properly mix.
9.2 The use of distilled or de-ionized water is recommended
to minimize the chance of adding harmful impurities into the
battery.
SECTION 10
10.0 TAP CONNECTIONS
GNB advises against tapping portions of the battery as this
condition may cause unbalanced charging. The untapped
portion may get overcharged while the tapped portion may
become undercharged resulting in poor performance and
reduced life.
SECTION 11
11.0 Pilot Bloc
11.1 A pilot bloc is selected in the series string to reflect
the general condition of all blocs in the battery regarding
specific gravities, float voltage and temperature. It serves
as an indicator of the battery condition between scheduled
maintenance periods.
11.2 It is recommended that a different pilot bloc be selected
each year.
SECTION 12
12.0 Records
12.1 A complete recorded history of the battery operation is
required. These records will show when corrective action
may be required to eliminate charging, maintenance or
environmental problems. These records will also be required
for consideration of warranty.
12.2 Data should be recorded on the Stationary Battery
Maintenance Report shown at the end of this manual.
Report headings should be filled in completely during the
actual dates(s) of installation.
12.3 Upon completion of the initial charge and with the
battery floating at the recommended float voltage for one
5
SG Float VPC
1.215 2.17-2.25
1.250 2.25-2.35

week, read and record individual cell voltages, connection
resistances, specific gravities (corrected to 25°C / 77°F),
ambient temperature plus cell temperatures and electrolyte
levels for 10% or more of the cells. The cell temperature
readings should be taken at each step/tier of the rack to
reflect the actual conditions.
12.4 The first set of readings will be the basis for comparison
with subsequent readings to reflect possible operating
problems and the need for corrective action.
12.5 Monthly - Observe the general appearance and
cleanliness of the battery. Record battery terminal voltage.
Check electrolyte levels and adjust if necessary. Check
for cracks in the battery and any signs of leakage. Note
any evidence of corrosion at terminals and/or connectors.
Record pilot cell voltage, specific gravity and temperature.
12.6 Quarterly - Supplement the monthly inspection and
record keeping with all battery voltages and specific gravities.
Check and record the electrolyte temperature of one cell on
each level of the rack(s).
12.7 Annual - Supplement Quarterly reports by tightening all
bolted connections to the specified torque values. Record
connection resistances of each battery post to battery post,
battery post to terminal. Remake any connections that
are more than 20% above installation base value. Check
integrity of the rack.
12.8 Record dates of any equalizing charges as well as
total quantity of water when added. Always record any
maintenance and/or testing conducted.
SECTION 13
13.0 Capacity Testing
When a capacity discharge test is desired, it is recommended
that it be performed in accordance with the latest revision of
IEEE-450, IEEE Recommended Practice for Maintenance,
Testing, and Replacement of Vented Lead-Acid Batteries for
Stationary Applications.
An equalizing charge, as described in Section 7.2 must
be completed within 7 days prior to the capacity test. The
batteries must be returned to float charging immediately after
the equalize charge completes. Allow the batteries to float at
least 72 hours prior to capacity discharge.
After the capacity discharge has completed, the batteries
can be recharged in the shortest amount of time by applying
an equalize charge
