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. 2 Wire Gauge Size Amperage 14 12 10 8 6 4 2 1 00 25 30 40 55 75 95 130 150 195 0000 260 Table 1 – Wire gauge sizing Flooded Lead Acid Terminals Terminal connections should be tightened to 25 ft/lbs or 33 Nm for all terminals.

Multiple parallel connection create unequal string resistances, resulting in possible cell damage or failure. 4 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. Voltage Regulated Charger – UU 0.35 BULK CURRENT (X C20 RATE) B = 0.25 x C20 (1max = 0.35 x C20) 0.25 ABSORPTION FLOAT 2.60 2.03 2.00 1.98 2.50 A = 2.45V/Cell (+/- .05V/Cell) 0.20 2.40 F = 2.3V/Cell (+/- .25V/Cell) 0.15 2.30 1.86 0.10 0.05 0.00 Temperature: 25ºC (77ºF) Temperature Coefficient: -4mV/ºC/cell (-2mV/ºF/cell) B=Bulk A=Absorption F=Float CHARGING TIME: NO LIMIT 12=0.007 x C20 2.20 VOLTAGE PER CELL 0.30 2.70 2.07 2.10 2.00 1.75 5 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%).

However, it is important to adhere to the termination criteria mentioned below to minimize the chance of excessive over-charge. See Figure 2 for the recommended constant current charge profile. 0.30 2.70 BULK CURRENT (X C20 RATE) B = 0.25 x C20 (1max = 0.35 x C20) 2.07 ABSORPTION TERMINATION Voltage varies with age 2.03 2.00 1.98 0.25 A = 2.45V/Cell (+/- .05V/Cell) Termination: F= 2.5mV/Cell/hr or 105-110% recharge 2.60 2.50 0.20 2.40 0.15 2.30 1.86 0.10 0.05 0.00 Temperature: 25ºC (77ºF) Temperature Coefficient: -4mV/ºC/cell (-2mV/ºF/cell) B=Bulk F=Float A=Absorption 12=0.01 x C20 2.20 2.10 2.00 CHARGING TIME: <=16 HRS VOLTAGE PER CELL 0.35 1.75 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. 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 Storage Temperature 86°F (30°C) 104°F (40°C) 2.43V 2.39V 2.26V 2.22V Refresh Charge Interval Below 68°F (20°C) 9 Months 68°F (20°C) - 86°F (30°C) 6 Months Higher than 86°F (30°C) 3 months 7 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. 8 Lead Acid Battery Charging Temperature 2 Volt Bulk/Absorption 0˚C to 16˚C 17˚C to 27˚C 28˚C to 40˚C Float Equalization 2.5 Volts 2.4 Volts 2.36 Volts 2.19 Volts 2.58-2.67 Volts System Voltage 12 Volt 24 Volt 15.0 Volts 30.0 Volts 14.4 Volts 28.8 Volts 14.16 Volts 28.32 Volts 13.14 Volts 26.28 Volts 15.48-16.02 30.96 - 32.04 Volts Volts 48 Volt 60.0 Volts 57.6 Volts 56.64 Volts 52.56 Volts 61.92 - 64.08 Volts Table 2 – Charge parameters 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. 10 % Charge 100 75 50 25 0 Specific Gravity* (SG) 1.255 – 1.275 1.215 – 1.235 1.180 - 1.200 1.155 - 1.165 1.110 - 1.130 Table 3 – Specific Gravity vs State of Charge *PLEASE NOTE: Specific Gravity is dependent on the electrolyte temperature.

To adjust, add/subtract 0.003 for every 5°C (10°F)byincrease/decrease. the battery manufacturer vent open 1/4” - 1/2” Electrolyte level Figure 7 – Electrolyte level Electrolyte should be kept at 1/2” below vent tube. Caution: Do not add water or electrolyte to cells before initial charging unless plates are exposed. If so, add distilled water until plates are submerged. Please contact Rolls Technical Support if you 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. Quick Checklist Shipping · All parts are included · No acid spill · No visual damage to the batteries Installation · Necessary personal protective gear being worn properly · All electrical components are turned off · Acid spill cleanup material at hand Initial Charge · Verify electrolyte levels (adjust if needed) · Measure specific gravity · Set up battery charge voltage/current limits General · Safety first! 15 Warranty We build one mean battery and we back them with comprehensive warranties that lead the industry in length of coverage.

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. 19 Contacts Surrette Battery Company Ltd.
