MANUAL
Rolls Battery has been manufacturing deep cycle lead-acid batteries since 1935.
Experience gained has helped us achieve an unmatched reputation along with specific
measures to obtain the maximum performance and life from our product. This manual
describes the recommended charging, equalization and preventive maintenance
procedures for Rolls batteries in order to maximize battery life.
Equipment Needed
· Goggles, rubber gloves and rubber boots
· Distilled water
· Baking soda
· Voltmeter
· Hydrometer
· Battery charger
Safe Handling Procedure
Always wear acid-resistant clothing, PVC gloves, goggles and rubber boots – especially
where there is risk of splashing. Always keep the batteries in an upright position. Always
have plenty of water available in case of acid spillage.
Inspection
Upon arrival, check the battery for visible damage (i.e. cracks, dents, deformation
and other visible abnormalities). Verify connections, assure that they are clean. If
the battery is dirty, or if any minor amount of acid has spilled onto the case, check
cleaning section of this manual. Any fluid on or around the battery could indicate
damage or improperly sealed case. Please verify the polarity of the terminals.
In the event of leak or damage please contact your retailer or Rolls Battery Company
Limited to determine if the battery needs replacement.
Installation
Rolls offers batteries for a wide variety of applications. No matter the application,
always be certain that the battery is properly secured, free of contaminants and that all
connections are in good contact with the terminals. Contact your retailer or refer to Rolls
Battery Technical Support.
Battery Orientation
Flooded lead acid batteries must be kept in an upright position at all times. Electrolyte in
the battery will spill if tilted.
Cable Sizing
The size of the cables used should be proportionate to the amount of amperage in your
system. See Table 1 for maximum current carrying capacity based on cable gauge.

Parallel/Series Connections:
Certain applications demand more voltage or more capacity than one battery’s output.
By arranging the connection configuration, one is able to increase the output voltage,
output capacity or both if needed.
To increase voltage, connect the batteries in series as shown in Figure 1.
Example:
Battery Voltage = 6V each
Battery Capacity = 400 AH each
System Voltage = 12V
System Capacity = 400 AH

Rolls AGM Battery Charging Instructions
To maximize the life of your Rolls battery, it is important that it is properly charged.
Over and under-charging a Rolls battery will result in shortened service life. The best
protection from improper charging is the use of a quality charger and routinely checking
that the charger current and voltage settings are maintained. Please review the following
Rolls Battery Charging Instructions.
AGM Charger Inspection
The charger cabling should be insulated and free of breaks or cuts. The cable connectors
should be clean and properly mate with the battery terminals to ensure a snug connection.
The charger’s AC cord should be free of breaks or cuts and the wall plug should be clean.
AGM Charging Guidelines
Fully charge batteries after each use. Charge in a ventilated area as gasses may be
released through the pressure relief valve if the batteries are excessively over-charged.
Never charge a frozen battery. Ideal charging temperatures: 32°F – 104°F (0°C – 40°C).
AGM Charging Characteristics
If the charger has a setting for AGM, use this setting to charge your Rolls battery.
To maximize your battery life, a voltage regulated charger with temperature compensation
is strongly recommended. See Figure 1 for the recommended voltage regulated
charge profile.

AGM Bulk Stage
The charger should deliver the initial current B until the voltage limit A is
reached. Absorption Stage – the charger should maintain the voltage A until
the current tapers to B. The initial charge current is recommended to be set at
B = 0.25 X C20 (Imax = 0.35 X C20) in order to fully charge the batteries within a
reasonable amount of time. It can be set lower, however; please be aware that
charge time will increase so make sure the batteries have enough time to fully charge
before being put back into service. Rolls batteries have a low internal resistance
allowing them to be charged at a higher current, therefore, faster than conventional
flooded/wet batteries.
AGM Float Stage and Termination
The charger can maintain the current B indefinitely or until the charger is shut off
or unplugged. This stage is ideal to maintain battery state of charge. Make sure the
temperature compensation is programmed as specified in Figure 1 (-4mV/°C/cell or
-2mV/°F/cell) or manually adjust the voltage setting for temperatures varying from
25°C (77°F). As the temperature decreases, the voltage should be increased and as the
temperature increases the voltage should be decreased. The profile in Figure 1 can be
used with or without the float stage. Without the float stage, recharge can be terminated
based on time (this will need to be determined as it will vary with depth of discharge and
charge current) or percentage recharge (105%-110%).

AGM Termination
If the charger can be programmed, the charge should terminate when the voltage stops
increasing over time. This is called a float termination. The charge should terminate
when the float is equal to 2.5mV/cell/hour. The charge time in the final phase should not
exceed 8 hours and the total charge time should not exceed 20 hours. The percentage
recharge should be between 105%-110%.
AGM Refresh Charge
If Rolls AGM batteries are properly charged they should never require an equalizing
charge. If they were not properly charged and there is a decrease in capacity, recharge
the batteries and make sure they complete the entire charge cycle. If the batteries are
stored for extended periods of time, recharge them as follows

Activation of a Dry Battery (Lead Acid)
Special order batteries can be shipped dry (acid shipped separately). To activate these
batteries, start by removing the vent caps. Using approved battery grade electrolyte
(1.265), fill each cell halfway between the plates and the bottom of the vent well tube.
(See Figure 4 on page 11.) It is important not to over fill the cells as the acid will expand
upon charging. If the cells are too full, the acid will spill out of the top of the cells.
Allow electrolyte to saturate into the plates and separators for at least 90 minutes. The
temperature of the electrolyte will rise and the specific gravity will drop. Once this is
complete, place the batteries on charge at the finishing rate (5% of the 8 or 20 hour
rate). The rate may be increased if the battery does not begin to gas. Do not let the
cell temperature exceed 115° F (46° C). If the temperature becomes excessive or the
cells begin to gas vigorously, reduce the rate of charge. Continue charging until the cell
(or cells) reaches within .005 points of the specific gravity of the filling electrolyte
corrected for 77° F (25° C). We recommend to continue charging for an additional 60
minutes to insure no further rise in specific gravity.
Top up or remove electrolyte as necessary for proper level. Never add electrolyte
(only approved water) after activation. Replace vent caps and remove any
spillage of electrolyte. If necessary, clean with bicarbonate of baking soda and
water (100 grams of soda to one litre of water). Rinse with water and wipe dry.
Ensure that the soda solution does not get into cells.
*Do not place on charge until electrolyte temperature is below 35°C.

Note: The most common type of charge method at present is the three stage plus equalization.
This outline is based on this type of charging method. Check with your charger manufacturer
for specific settings for their equipment. Please note, if “topping up” with water is required
more than once every two (2) months, the voltage settings are too high on your system.
Activating Instructions/Maintenance for a Wet Battery (Lead Acid)
Caution: Always wear the proper personal protective equipment (goggles, gloves,
clothing) when handling batteries and electrolytes.
WARNING:
· WET BATTERIES MUST BE FULLY CHARGED BEFORE BEING DELIVERED TO THE END
USER. PLEASE REFER TO THE “INITIAL CHARGE OF WET BATTERIES” SECTION OF
THIS DOCUMENT.
· ONLY ADD DISTILLED WATER TO WET BATTERIES. UNLESS INSTRUCTED
BY ROLLS TECHNICAL SUPPORT, NEVER ADD MORE ACID TO THE BATTERIES
AT ANY TIME.
· FAILURE TO DO SO WILL RESULT IN MALFUNCTION AND VOID THE WARRANTY.
Cleaning
Batteries should be kept clean at all times, including storage or usage. If stored in a dirty
area, regular cleaning should be performed. Before doing so, ensure that all the vent
caps are tightly fastened. Using a solution of water and baking soda (100g per litre),
gently wipe the battery and terminals, then rinse with water.
Initial Charge of Wet Batteries (Lead Acid)
1. Inspect batteries for damage. Important: read warning label on batteries
before proceeding.
2. Wet batteries are fully charged and tested before shipping, but do self-discharge
during transportation and storage. The first charge brings the battery to an operational
state. Before this charging process, the cell electrolyte level should be checked, making
9
sure the electrolyte covers the plates. If this isn’t the case, add distilled water until all
the plates are submerged. It is important not to over fill because the level will rise during
the charge process.
3. Check for correct polarity. Attaching the positive and negative voltmeter lead to the
positive and negative battery terminal should give a positive voltage reading. If it is
negative, a reverse polarity condition exists and you should contact your dealer or Rolls
Battery Technical Support.
4. Place batteries on charge. Please see Table 2 – charge parameters for required
charging settings. Do not let the cell temperature exceed 125°F (51.8°C). If the
temperature becomes excessive or the cells begin to gas vigorously, reduce the rate
of charge. Continue charging until all cells reach the specific gravity of the filling acid.
All cell voltages should be even (1.265 - 1.275).
5. See Initial Charge below.
Initial Charge
A battery may not be fully charged when received. The first charge brings the
battery to an operational state. Before this charging process, the cell electrolyte
level should be checked. Please ensure the electrolyte (liquid) covers the plates.
If this isn’t the case, add distilled water until all the plates are just submerged.
It is important not to over fill because the level will rise during the charging process.
Charge voltages are indicated in Table 2.
The electrolyte’s specific gravity is the most accurate measurement and it is
recommended to verify its value to determine if the cells are, in fact, fully charged.
The specific gravity should be constant for 3 hours for an accurate full charge
reading. Check the state of charge as related to specific gravity. Initial charging
may take 10 hours. Once the battery is fully charged, verify the electrolyte level
in the cell once more. The fluid should be 1/4 – 1/2 inch below the vent tube on
each cell as shown in Figure 7. Carefully add distilled water to adjust the level
if needed.

have any questions or concerns.
Bulk Charge
The first part of the charging process is the bulk charge. This is when the maximum
amount of current flows into the battery bank until a desired voltage is reached. The
recommended maximum current is 15% of the AH capacity of the battery bank based
on the 6 hour rate. A lower current can be used, but this will prolong the charging time.
Bulk charge voltage set points are outlined in Table 2.
Absorption Charge
Arguably, the most important part of the charge cycle is the absorption charge. Since
the bulk charge only recharges the battery bank to an 80% level, the absorption charge
completes the charging cycle. Most chargers on the market have a timer that allows the
user to adjust the duration for the required time to return the battery to full charge. In
order to set the correct time, a simple calculation is required. With the help of the 20 AH
capacity, you can figure out the remaining charge required for the battery bank.
11
As stated previously, the bulk charge brings the bank to an 80% charging level.
The remaining 20% of the capacity is a function of time and current. The charger will
maintain current level until the bulk set point has been reached, then the charger
switches to the absorption timer. The current levels start decreasing as the internal
resistance in the battery increases. Assume over the time of the absorption charge that
50% of your maximum charge current will be available (this is factored into the equation).
0.42 = (20%/50%) + 5%. 5% is added due to losses.
ABSORPTION CHARGE TIME
Where : T = 0.42 x C /I
T = ABSORPTION CHARGE TIME
C = 20 hr RATED CAPACITY (of the Bank)
I = Charging Current ( 10% of C20 max)
0.42 = ( 20%/50%) + 5% (5% is added due to losses)
EXAMPLE
2 Banks of 6 V S-530 models
20 hr rate = 400 x (2 strings) = 800 ah
I = 10% of 800ah = 80 amps. If charger is 60 amps max, 60 is used
T = 0.42 x 800/80 = 4.2 hrs OR T = 0.42 x 800/60 = 5.6 hrs
Float Charge
The batteries require a certain amount of voltage in order to maintain full charge when
no load is applied. The power supply keeps the batteries at a constant full state of
charge. In order to prolong battery life, the float settings on the power supply should be
adjusted to the voltage indicated in Table 2.
Equalization - Preventative
Individual cells will vary slightly in specific gravity after a charging cycle. Equalization
or a “controlled overcharge” is required to bring each battery plate to a fully charged
condition. This will reduce stratification and sulfating, two circumstances that shorten
battery life. Equalization of the battery bank is recommended every 30 to 180 days,
depending on the usage of the individual system. To equalize the cells, charge the
batteries until the voltage elevates to the “Equalization” voltage shown in Table 2. Charge
parameters and maintain for 2 to 3 hours per bank. A constant SG for 30 minutes is a
good indication of cell equalization. It is recommended to water the battery cells half way
through the equalization. This will assure the water is mixed with the electrolyte.
Frequency
It is recommended to balance charge the batteries before usage. Corrective equalization
needs to be performed if symptoms arise such as a constantly running generator (low
capacity) or the battery bank will “not hold a charge”. These symptoms are typical of
a heavily sulfated battery. If a battery is not being fully charged on a regular basis or
limited equalization is performed using a generator, sulfating will occur from “deficit”
cycling. This undercharge condition can take months before it becomes a major and
noticeable problem.
12
METHOD
Corrective equalization can take a very long time depending on the degree
of sulfation.
1. If you have a recombination cap, remove during equalization.
2. Set the charging controls to the recommended equalization settings according
to voltage.
3. Charge at a low DC current (5 A per 100 AH of battery capacity). If grid power is not
available, use solar panels or a good DC source when possible. At high voltages,
charging with generator can be difficult and hard on the inverter.
4. Once every hour, measure and record the specific gravity and temperature of a test
cell. If the temperature rises above 46ºC and approaches 52ºC, remove the batteries
from charge.
5. If severely sulfated, it may take many hours for the specific gravity to rise.
6. Once the specific gravity begins to rise, the bank voltage will most likely drop, or
the charging current will increase. The charging current may need to be lowered if
temperature approaches 46ºC. If the charge controller was bypassed, it should now
be used or put back in line.
7. Continue measuring the specific gravity until 1.265 is reached.
8. Charge the batteries for another 2 to 3 hours. Add water to maintain the electrolyte
above the plates.
9. Allow bank to cool and check and record the specific gravity of each cell.
The gravities should be 1.265 ± 0.005 or lower. Check the cell electrolyte levels and
add water if necessary.
It is recommended that a specific gravity reading of one pilot cell is measured
and recorded on a regular basis when it is thought that the bank is fully charged.
The measurement should be compared to previous readings. If the measurement is lower
than the previous reading, a longer absorption time and/or higher voltage setting should be
used. The longer the absorption time and the higher the bulk voltage, the more water will be
consumed but less equalization will be required.
Note: The specific gravity should rise as the cells use water. Look for trends in the specific
gravity over a period of time and make small adjustments as necessary.
13
Temperature Probe
For additional data and safety, many people choose to install temperature probes inside
the battery banks. Regardless of the size of the battery bank, the probe should be
installed on the side of one battery, below the liquid level on a battery placed in the
center of the bank. The main factor to look for is maximum temperature. The battery
bank should not exceed an operating temperature of 50ºC.
Figure 8 – Side of the battery, middle of the bank and below the liquid level
Cleaning
Batteries should be kept clean at all times. If stored in a dirty area, regular
cleaning should be performed. Before doing so, assure that all the vent caps are tightly
fastened. Using a solution of water and baking soda (100g per litre), gently wipe the
battery and terminals with a damp sponge, then rinse with water.
Pulse Charging
Pulse charging has shown that the banks do not get as sulfated as one with the traditional
3-step charging, but will not eliminate the need for controlled, preventive equalization.
The benefit of pulse charging is that the bank will need less overcharge and hence less
maintenance.
Battery Additives
Most battery additives are mainly a form of a common preservative, EDTA.
These additives help to increase the solubility of the sulfate in the electrolyte
(common salt effect). Some additives contain cadmium sulfate, which could
cause disposal problems in the future. These additives are not beneficial and
are not recommended.
Storage Procedure
Keep the batteries clean and always store in a cool, dry area. Where acid is
stored or handled, good ventilation is necessary. Keep the bungs on the containers at
all times.
14
Spillage Procedure
Small spills may be neutralized using water. Spray the spill from a windward
location wearing protective equipment. Direct the jet to the outside of the
spillage, working your way inward towards the center. Larger spills should be
contained using soda ash, sand or dirt and finally washed down with water
once absorbed.
Disposal Procedure
Batteries must NEVER be disposed in household waste. To reduce environmental
impacts, bring your battery to a certified recycling depot at the end of its life.
Note: Lead-acid batteries are 97-98% recyclable.
Rolls Batteries have >66% recycled lead.

Warranty
We build one mean battery and we back them with comprehensive warranties
that lead the industry in length of coverage. We’re confident that our batteries
will perform time after time, year after year. But should a problem arise, you
can be confident that you’re covered better than any other battery warranty in
the business.
Rolls, herein referred to as the Company, warrants that batteries sold by it are
merchantable and free of defects in workmanship and material at the time they are
shipped from the Company’s factory.
In the event that the Company makes a drop shipment to a distributor’s customer,
that customer must be instructed to perform an inspection of the goods BEFORE
signing the delivery slip. The Company is not responsible for damaged product
reported after shipment has been signed “Received in Good Condition”. NOTE: ALL
SHIPMENTS SHOULD BE THOROUGHLY INSPECTED FOR DAMAGE BEFORE
SIGNING THE DELIVERY SLIP. The Company will replace or, at its option, repair any
Rolls Battery sold by it that fails to conform to the warranty stated above on a
NO CHARGE BASIS as follows:
For warranty terms and conditions, please refer to the Products section on the website
for model-specific details: www.rollsbattery.com. A warranty claim form may be found
on the website.
To claim a manufacturing warranty, proof of purchase must be presented, showing the
date of purchase and the battery’s serial number. The battery must be tested by an
authorized battery outlet for actual defect, and upon confirmation of the defect, the
warranty will be administered.
The warranty does not cover shipping damage, cracked covers, cracked cases, bulged
cases from heat, freezing or explosion, discharged batteries or the use of undersized
batteries damaged from electrical equipment. This warranty covers only manufacturing
defects.
The Company makes no warranty with respect to its batteries other than the warranty
stated above. All implied warranties of merchantability and all expressed and implied
warranties of any other kind are hereby excluded.

LEAD Acid Battery Glossary
Absorbed (or Absorptive) Glass Mat
A technique for sealed lead-acid batteries. The electrolyte is absorbed in a matrix of
glass fibers, which holds the electrolyte next to the plate and immobilizes it, preventing
spills. AGM batteries tend to have good power characteristics, low internal resistance,
and good behavior during charging.
Amp, Ampere
Unit of electrical current. Abbreviated “A”.
Amp-hour
Unit of electrical energy, one amp of current flowing for one hour. Abbreviated Ah.
Cell
A single battery canister usually grouped together with other cells to form battery packs
of different voltages and amperages. Example: One NiCD cell is 1.20 volts; therefore, six
cells packaged together makes a 7.2 volt battery pack.
Cycle
A “cycle” is a somewhat arbitrary term used to describe the process of discharging a
fully charged battery down to a particular state of discharge. The term “deep cycle”
refers to batteries in which the cycle is from full charge to 80% discharge. A cycle for an
automotive battery is about 5%, and for telephone batteries is usually 10%.
Electrolyte
An electrically conductive medium in which current flow is due to the movement of ions.
In a lead-acid battery, the electrolyte is a solution of sulfuric acid. In other batteries, the
electrolyte may be very different.
Flooded Cell
A design for lead-acid batteries. The electrolyte is an ordinary liquid solution of acid.
Flooded cells are prone to making gas while being charged. They must be periodically
checked for fluid level and water added as necessary. Flooded cells are also typically
less expensive than AGM or gel type lead-acid batteries.
Hydrometer
A tool for testing the specific gravity of a fluid, such as the electrolyte in a flooded
battery. Typically, a squeeze-bulb is used to suck up a sample of the fluid, and a float
indicates the specific gravity.
18
Specific Gravity
The density of a material, expressed as the ratio of the mass of a given volume of the
material and the mass of the same volume of water; a specific gravity greater than 1
means heavier than water, less than 1 means lighter than water. The specific gravity of
the electrolyte in a battery can be used to measure the state of charge of the battery.
Sulfation
Even though lead sulfate is created in the materials of plates during normal discharging,
this term is used to describe the generation of a different form (large crystals) of lead
sulfate which will not readily convert back to normal material when the battery is
charged. Sulfation occurs when a battery is stored too long in a discharged condition,
if it is never fully charged, or if electrolyte has become abnormally low due to excessive
water loss from overcharging and/or evaporation.
Volt
The unit of measurement of electrical potential or “pressure”. Most batteries come in
2, 4, 6, 8 or 12 volt models.
