Introduction The principle of gas recombination, which limits the release of gas, allows the batteries to be installed in the widest possible range of sites and in contact with modern technology. The purpose of this operating guides is to provide you with technical information to gain a better understanding of the gasrecombination battery OPzV range and will enable you to use it more effectively. 2

I/ The principle of the gas recombination tubular gel battery 1 Operating principle In a traditional lead acid battery, overcharging leads to a release of hydrogen and oxygen, a certain amount of water is lost and has to be replaced regularly by topping up. In a gas recombination battery, the internal design of the cell allows the oxygen produced at the positive plates to diffuse toward the negative plates : The oxygen reacts chemically with the spongy lead of the active material to form lead oxide. The sulphuric acid of which the electrolyte is composed then reacts with this lead oxide to form lead sulphate and water. The lead sulphate thus formed is transformed electrochemically into lead, to return sulphuric acid. As long as the battery remains fully charged, this equilibrium is maintained. Schematically, we then have the following reactions : At the end of the charge or if overcharging, oxygen gas is released at the positive plate. The oxygen diffuses across the gelled electrolyte and the microporous separator to the negative plate. The oxygen reacts chemically with the spongy lead of the negative plate to form lead oxide. The sulphuric acid reacts with this lead oxide, giving lead sulphate and water. Part of the spongy lead is thus chemically discharged to the lead sulphate state and the water consumed at the positive plate is regenerated. 2 O 2 + + 1/2O 2 + 2e Pb + 1/2O 2 PbO PbO + 2 SO 4 PbSO 4 + 2 O The spongy lead which was chemically discharged at the negative plate is recharged chemically. PbSO 4 + 2 + + 2e Pb + 2 SO 4 Electrolyte 2 Conventional cell Oxygen and ydrogen escape to the atmosphere O 2 O 2 OPzV Oxygen evolved from positive plate transfers to negative and recombines to form water. + O 2 + 2 Conclusion Due to the gas recombination reaction in the awker OPzV cells, water is recombined nearly at the same rate as it is consumed under float charge conditions and no topping up water during the lifetime of the cells is required.

II/ Application and use of the OPzV batteries The application possibilities are multiple as back up supplies in telecommunications, telephony, power generating stations and distribution systems, railway, airport or seaport signalling, computing, lighting, the armed forces, in the medical field, etc. giving independent operation between 1 hour and 24 hours to such installations. 1 Standby applications 11 Float voltage : The specific gravity of the gelled electrolyte is 1.260, which allows for float charging theses OPzV batteries at the same operating conditions as conventional flooded lead acid batteries.the float charge voltage is 2.23 V/cell. Therefore conventional vented awker OPzS ( tubular lead acid batteries) can be replaced by valve regulated awker OpzV batteries whithout charger modifications. The batteries are kept under a floating voltage of 2.23 volts per cell at a temperature of 20 C. This float voltage should be set to match the prevalling temperature, in accordance with the following table. 1 Application stationnaire 1.2 Discharging : End of discharge voltage according to the discharge time Discharge Time (t) 1 h < t < 5 h 5 h < t < 8 h 8 h < t < 24 h End voltage (volt) 1.70 V 1.75 V 1.80 V Temperature (C ) 0 C 10 C 20 C 30 C 35 C (Référence T C) Float voltage (volt) 2.35 V 2.28 V 2.23 V 2.20 V 2.19 V Although the tables of characteristics show end voltages down to 1.60 volts, the voltage values shown above are recommended in order to avoid a toodeep discharge of the battery. Due to the phenomena of gas recombination a difference of ± 2.5 % for an individual cell voltage can be observed. owever the total voltage of the battery shall be within the limits stated above. 6

1.3 Recharging : The battery should be recharged by using a unique floating and recharge voltage at 2.23V/cell at 20 C.No current limitation is required in the majority of application cases. ge If the battery has to be charged more quickly, a recharge voltage of 2.35 volts per cell can be used with current limited to 0.4C 10 Percentage discharge Mean charging time in accordance with percentage discharge and recharging voltage per cell with current limited to 0.4C10 Recharging voltage State of charge 50% 60% 70% 80% 90% 95% 100% 10% 2.23V 2.35V 2 h 00 1 h 45 12 h 00 7 h 00 30% 2.23V 2.35V 1 h 15 1 h 00 4 h 00 3 h 00 8 h 00 6 h 00 24 h 00 14 h 00 50% 2.23V 2.35V 0 h 45 0 h 30 1 h 30 1 h 15 4 h 00 3 h 00 8 h 30 5 h 30 15 h 00 10 h 00 38 h 00 22 h 00 80% 2.23V 2.35V 1 h 00 1 h 00 1 h 30 1 h 30 3 h 00 2 h 30 7 h 00 5 h 00 13 h 00 9 h 15 25 h 00 15 h 00 56 h 00 34 h 00 100% 2.23V 2.35V 2 h 00 2 h 00 2 h 30 2 h 30 4 h 30 4 h 00 10 h 00 7 h 15 20 h 00 14 h 00 35 h 00 24 h 00 80 h 00 50 h 00 Recharging voltage according to temperature : Temperature (C ) 0 C 10 C 20 C 30 C 35 C Charging voltage (volt) 2.45 V 2.40 V 2.35 V 2.32 V 2.30 V * Note : If the charger does not permit an adjustement of the float voltage in relation with the temperature, it is possible to set a float voltage value in recharging voltage value according to the temperature ranges as indicated in the table hereafter. Temperature (C ) 10 C to 5 C 5 C to 15 C 15 C to 30 C 30 C to 45 C Float voltage (Vpc) 2.40 V 2.30 V 2.25 V 2.20 V Recharging voltage (Vpc) 2.50 V 2.40 V 2.35 V 2.30 V 1.4 Ripple current : Unacceptable levels of ripple current from the charger of the load can cause permanent damage and a reduction in service life.it is recommended to limit the continuous ripple current to 0.05 C 10 (in amperes) as recommended value, never exceed 0.1 C 10. 7

2 Battery cycling Definition Battery cycling implies use in a regular cycle, with full discharge followed by recharging on a daily or weekly basis for example. The number of such cycles which can be obtained is typically over 1200, in conformity with the IEC8962. Important note : For all applications which use the OPzV type battery in a cycling system, it is recommended that the technical department of the awker company be contacted so that the technical parameters can be specified for the precise cycling programme in question. 3 Effect of temperature on battery capacity The temperature has an effect on the battery capacity available. The following table gives the relevant details for a temperature of 20 C.

IV/ Battery calculations The following calculations will enable you to determine which unit in the OpzV range you require in order to supply the power you need, and in the specified temperature conditions : here discharge includes current surges, please consult our commercial department. Constant discharge case Power required : 23.7 k Minimum voltage : 376 volts Maximum voltage : 484 volts Back up time required : 4 hours For a temperature of 20 C, the float charge voltage is 2.23 volts per cell. Maximum number of 2V cells : 484 V/2.23 V = 217 Discharge current : 23700 /376V = 63A Minimum voltage per 2 V cell : 376/217 = 1.74 V Refer to the table of electrical performance characteristics of the OPzV cells for an end voltage of 1.75 volts. For a discharge current of 63A or more and a discharge time of 4 hours, we find 68.4V A for the cell 6 OPzV300 Type of battery : 217 cells 6 OPzV300 (320Ah in C10 for 1.80 V) For a temperature of O C : the float charge voltage is 2.35 volts per cell. Maximum number of 2 V cells : 484V/2.35 V = 206. Discharge current : 23700 /376 V = 63A Minimum voltage per 2 V cell : 376V/206=1.83 V Now refer to the section on the use of the OpzV accumulators, at the paragraph entitled " Effect of temperature on battery capacity, to find the capacity correction factor in this case it proves to be 0.74. The equivalent discharge current will be : 63/0.74 = 85 A Now go to the table of electrical performance characteristics of the OPzV range for an end voltage of 1.85 volts. For a discharge current of 85 amps or more, the cell in the OPzV range which corresponds to a 4 hour discharge time is the 6 OPzV420. The battery is thus made up of 206 cells of type 6 OPzV420 (560 Ah at C10 for 1.80 V end voltage). Important note : In a case where the ambient temperature varies, the calculations should be performed on the basis of the lowest temperature Example : For 11 months of use at 20 C and 1 month at 0 C, calculate the number of cells with a float voltage of 2.23 volts per cell, and find the corresponding accumulator with the loss of capacity transferred to the discharge current. 17

V/ Installation of the battery 1 arning The cells of the EG battery are already charged when delivered, and are fitted with a protective cap on each terminal. They should be unpacked with care. Avoid shortcircuiting terminals of opposite polarity, because these units are capable of discharging at a very high current, even if the lid or the container happens to be damaged. 2 Unpacking the battery Each shipment of OpzV batteries is accompanied by a packing list and installation instructions. The packing list should be checked, and the Sales DepartmentStandby Batteries should be told immediately of any missing items. The markings on the lid should be read carefully : The type of cell The voltage in volts The capacity in ampere hours The storage limit date The float charge voltage at 2025 C The arrow must always point upwards if the batteries are placed in the prone position. 3 Setting up the battery stands Construction : Theses stands are in plasticcovered steels, and are notable for their : mechanical strength their adaptability their ease of assembly. The standard stretchers of 600,750,900,1200 and 1 mm are designed to result in space saving installations. Note : The symbol indicates that the accumulator is of the recyclable type. 18

Stand models : There are two ranges of stands to suit the position in which the accumulators are to be placed : 3.1 Standard stands for vertical cells See also the appendix on page 20. The various assembly options are dependent on : The number of cells of which the battery is composed The floor area available Importante note : The floor must possess the necessary loadbearing characteristics. Assembly of battery stands : The structure should be assembled in accordance with the exploded view and instructions supplied with the equipment. Check the correct fixing ot the chassis after fist checking the squareness. 1 and 2 levels 1 row 2 rows flat 3 rows flat ith 2 rows 3 levels Special designconsult our Sales Department Take up any irregularity in floor surface using shims. The uprights of 2 or 3 level stands for vertical cells and the 4 and 6 level stands for horizontal cells are best mounted on a well.

Standard stands for vertical cells : Length of the stand is determined by the combination of 5 different longitudinal beams (Length 600 mm, 750, 900, 1200 and 1 mm) in relation with the total length of cells. Standard stands for horizontal cells : Length of the stand is determined by the combination of 5 different longitudinal beams (Length 600 mm, 750, 900, 1200 and 1 mm) in relation with the total length of cells. Caution : Take into account the inbetween pillars. 21

4 Connecting of the cells in series : The number of cells in series will determine the total float voltage : U = V x N U = total float voltage V = float voltage for one cell N = number of cells In parallel : OPzV cells of the same ampere hour rating may be connected in parallel to give higher current capability.this connection in parallel will be preferably carried out through an equipotential wiring for an equal current distribution in each string. These is no technical reason for limiting the number of strings but for practical installation reasons, it is recommended not to exceed 4 strings in parallel especially if the battery is used in high discharge rates (standby time lower than 1 hour.). 5 General recommendations Do not wear clothing in synthetic materials, to avoid the generation of static potentials. Discharge any possible static electricity from clothes by touching an earth connected part. andle the battery cells with special implements provided (never lift the cells by their terminals). Use insulated tools. Place the cells beginning with the least accessible rows, spacing the cells as shown in the figure. Always ensure that the arrow on the cell lid is pointing upward if the cell is placed in the horizontal position. Consult the drawing for the correct position of the cell poles (positive = red washer, negative = blue washer). Before attaching the intercell flexible cables, check that all terminals are in the correct position. The battery cells are connected in series, that is with a positive pole connected to a negative pole. Clean the cells with nothing other than a dampened cotton cloth. The tightening torque for connections is 23 Nm (2.3 Mkg) to a 25 Nm (2.5Mkg). This maximum value must not be exceeded. 6 Safety All installation and ventilation must comply with the current regulations and norms (In France : norm NFC15100) Batteries must be installed in accordance with EN 50272 2 standard 7 Standards The OPzV range complies with the international standard : IEC 8962 Classified as long life according to the EUROBAT Guide 1999 awker production facilities worlwide are certified to ISO 9001 Low ventilation requirement according to EN 502722 The OPzV conforms to draft of DIN standard 40742 22

VI/ Battery storage 1 Calculating the storage time The storage time is indicated on the battery lid. This takes into account the shipping time of equipment, frequently quite lengthy (in the case of exports in particular). 2 Storage conditions The battery should be stored away from any moisture or source of heat. 3 Storage times The selfdischarge of OPzV batteries as a function of temperatures is as follows : 2% per month at 20 C 4% per month at 30 C 8% per month at 40 C In order to ensure that the battery can be charged easily after a long period of storage, it is recommended that batteries should not be stored fore more than the following periods without recharging : 6 per month at 20 C 4 per month at 30 C 2 per month at 40 C 4 Recharging stored batteries The batteries should be recharged at the float charge voltage to suit the temperature (2.23 volts at 20 C per cell for example) with a current limit of 0.4 C10 and for a minimum period of 96 hours. The battery will be charged when the charging current has remained constant for a period of 3 hours. 5 State of charge The battery state of charge can be determined approximately by measuring the open circuit voltage after the battery has been at rest for a minimum of 24 hours. State of charge 100% 70% 50% 20% Voltage 2.13V/cell 2.09V/cell 2.06V/cell 2.02 V/cell The necessity of a refreshing charge can also be determined by measuring the open circuit voltage of a stored battery. Refreshing charge is advised if the voltage drops below 2.07 V/cell. Failure to comply with these recommendations may compromise the life expectancy of the battery. 23

VII/ Commissioning Before bringing them into service, the batteries must be charged at a constant regulated voltage to match the prevailing temperature, for a minimum period of 48 hours. VIII/ Maintenance/checks Every month, check the total floating voltage at the battery terminals.it should be N x 2.23 volts at a temperature of 20 C, where N is the number of cells in the battery. Once each year, effect a reading of the voltage of cells constituting the battery. A difference of plus or minus 2.5 % between these individual floating voltages and the average voltage may be observed. This is due to the gas recombination process. A check on capacity ( independent operation on load) can be performed once a year. Safety hen carrying out any work on the battery, the applicable safety standards should be followed. Note : Keep a logbook battery in which the measured values can be noted as well as power cuts, discharge tests( current, time, T ) etc. The main factors causing reduction in the life expectancy of OPzV cells Deep discharges Poor regulation of the float voltage Poor quality (smoothing) of the charging current igh ambient temperatures 24
