The principle of gas recombination, which limits the release of gas, allows thebatteries to be installed in the widest possible range of sites and in contact withmodern technology.

The purpose of this operating guides is to provide you with technical information togain a better understanding of the gas-recombination battery OPzV range and willenable you to use it more effectively.

1 - Operating principleIn a traditional lead – acid battery, overcharging leads toa release of hydrogen and oxygen, a certain amount ofwater is lost and has to be replaced regularly by toppingup.

In a gas recombination battery, the internal design of thecell allows the oxygen produced at the positive plates todiffuse toward the negative plates :

- The oxygen reacts chemically with the spongy leadof the active material to form lead oxide.

- The sulphuric acid of which the electrolyte iscomposed then reacts with this lead oxide to formlead sulphate and water.

- The lead sulphate thus formed is transformedelectro-chemically into lead, to return sulphuricacid.

- As long as the battery remains fully charged, thisequilibrium is maintained.

Schematically, we then have the following reactions :

2 - ConclusionDue to the gas recombination reaction in the Hawker OPzVcells, water is recombined nearly at the same rate as it isconsumed under float charge conditions and no toppingup water during the lifetime of the cells is required.

The oxygen diffuses across thegelled electrolyte and themicro-porous separator to thenegative plate.

The oxygen reacts chemicallywith the spongy lead of thenegative plate to form leadoxide.The sulphuric acid reacts withthis lead oxide, giving leadsulphate and water.Part of the spongy lead is thuschemically discharged to thelead sulphate state and thewater consumed at the positiveplate is regenerated.

1 - Standby applications1-1 Float voltage :The specific gravity of the gelled electrolyte is 1.260,

which allows for float charging theses OPzV batteries atthe same operating conditions as conventional floodedlead acid batteries.The float charge voltage is 2.23 V/cell.Therefore conventional vented Hawker OPzS ( tubular

lead- acid batteries) can be replaced by valve regulatedHawker 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.

Due to the phenomena of gas recombination adifference of ± 2.5 % for an individual cell voltage can beobserved.However the total voltage of the battery shall be withinthe limits stated above.

1 - Application stationnaire1.2 Discharging : End of discharge voltageaccording to the discharge time

Although the tables of characteristics show end voltagesdown to 1.60 volts, the voltage values shown above arerecommended in order to avoid a too-deep discharge ofthe battery.

The application possibilities are multiple - as back–up supplies in telecom-munications, telephony, power generating stations and distribution systems, railway,airport or seaport signalling, computing, lighting, the armed forces, in the medicalfield, etc. - giving independent operation between 1 hour and 24 hours to suchinstallations.

1.3 Recharging :The battery should be recharged by using a uniquefloating and recharge voltage at 2.23V/cell at 20 °C.Nocurrent limitation is required in the majority ofapplication cases.

geIf the battery has to be charged more quickly, a rechargevoltage of 2.35 volts per cell can be used with currentlimited to 0.4C10

1.4 Ripple current :Unacceptable levels of ripple current from the charger ofthe load can cause permanent damage and a reductionin service life.It is recommended to limit the continuous

ripple current to 0.05 C10 (in amperes) as recommendedvalue, never exceed 0.1 C10.

* Note :If the charger does not permit anadjustement of the float voltage in relationwith the temperature, it is possible to set afloat voltage value in recharging voltagevalue according to the temperature rangesas indicated in the table hereafter.

2 - Battery cycling

Definition

Battery cycling implies use in a regular cycle, with fulldischarge followed by re-charging on a daily or weeklybasis for example.

The number of such cycles which can be obtained istypically over 1200, in conformity with the IEC896-2.

Important note : For all applications which use theOPzV type battery in a cycling system, it is recommendedthat the technical department of the Hawker companybe contacted so that the technical parameters can bespecified for the precise cycling programme in question.

3 - Effect of temperatureon battery capacity

The temperature has an effect on the battery capacityavailable. The following table gives the relevant details fora temperature of 20°C.

4 - Temperature rangeThe ideal ambient temperature for OPzV batteries is 20°C± 5°CThe operating temperature shall be in the range of 10 and 35°C

The maximum permissible temperature is 45°C

5 - Effect of temperature on lifeOperation of valve regulated batteries at temperatureshigher than 20°C will reduce life expectancy.Highertemperature increases the speed of chemical reactionsresulting in reduction of service life.A temperature increaseof 10 °C decreases the service life to half (law of Arrhenius)

The following calculations will enable you todetermine which unit in the OpzV range you requirein order to supply the power you need, and in thespecified temperature conditions :

Where discharge includes current surges, please consultour commercial department.

Constant discharge case

- Power required : 23.7 kW- 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 percell.

- Maximum number of 2V cells : 484 V/2.23 V = 217

- Discharge current : 23700 W/376V = 63A

- Minimum voltage per 2 V cell : 376/217 = 1.74 V

Refer to the table of electrical performancecharacteristics of the OPzV cells for an end voltage of1.75 volts.

- For a discharge current of 63A or more and a dischargetime of 4 hours, we find 68.4V A for the cell 6 OPzV300

- Type of battery : 217 cells 6 OPzV300 (320Ah in C10 for1.80 V)

For a temperature of O°C :

the float charge voltage is 2.35 volts percell.

- Maximum number of 2 V cells : 484V/2.35 V = 206.

- Discharge current : 23700 W/376 V = 63A

- Minimum voltage per 2 V cell : 376V/206=1.83 V

- Now refer to the section on the use of the OpzVaccumulators, at the paragraph entitled " Effect oftemperature on battery capacity, to find thecapacity correction factor- in this case it proves tobe 0.74.

- The equivalent discharge current will be : 63/0.74 = 85 A

- Now go to the table of electrical performancecharacteristics of the OPzV range for an end voltageof 1.85 volts.

- For a discharge current of 85 amps or more, the cellin the OPzV range which corresponds to a 4 hourdischarge time is the 6 OPzV420.

- The battery is thus made up of 206 cells of type6 OPzV420 (560 Ah at C10 for 1.80 V end voltage).

Important note :

In a case where the ambient temperature varies, thecalculations should be performed on the basis of thelowest temperature

Example : For 11 months of use at 20 °C and 1 month at0°C, calculate the number of cells with a float voltage of2.23 volts per cell, and find the correspondingaccumulator with the loss of capacity transferred to thedischarge current.

IV/ Battery calculations

18

1 - WarningThe cells of the EG battery are already charged whendelivered, and are fitted with a protective cap oneach terminal. They should be unpacked with care.

Avoid short-circuiting terminals of opposite polarity,because these units are capable of discharging at a veryhigh current, even if the lid or the container happens tobe damaged.

2 - Unpacking the batteryEach shipment of OpzV batteries is accompanied by apacking list and installation instructions.

The packing list should be checked, and the SalesDepartment-Standby Batteries should be toldimmediately 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 20-25 ° C

- The arrow must always point upwards if thebatteries are placed in the prone position.

Note : The symbol indicates that the accumulatoris of the recyclable type.

3 - Setting up the battery standsConstruction : Theses stands are in plastic-coveredsteels, and are notable for their :

- mechanical strength

- their adaptability

- their ease of assembly.

The standard stretchers of 600,750,900,1200 and 1500mm are designed to result in space- saving installations.

V/ Installation of the battery

19

Stand models : There are two ranges of stands to suit theposition in which the accumulators are to be placed :

3.1 - Standard standsfor vertical cells

See also the appendix on page 20. The various assemblyoptions are dependent on :

- The number of cells of which the battery is composed

- The floor area available

3.2 - Stands for horizontal cells(see appendix page 20)

Stand in a 4 and 6 levels are availableConnexion in front of the stand for easier maintenance.

Importante note :

The floor must possess the necessary load-bearingcharacteristics.

Assembly of battery stands :

- The structure should be assembled in accordance withthe exploded view and instructions supplied with theequipment.

- Check the correct fixing ot the chassis after fistchecking the squareness.

- Take up any irregularity in floor surface using shims.

- The uprights of 2 or 3 level stands for vertical cells andthe 4 and 6 level stands for horizontal cells are bestmounted on a well.

- These plastic-covered metal stands are electricallyinsulated and require no connection to the buildingearth.

- For the installation of cells in the horizontal position,always ensure that the arrow on the lid of each unit ispointing upward.

Standard stands for vertical cells :

Length of the stand is determined bythe combination of 5 differentlongitudinal beams (Length 600 mm,750, 900, 1200 and 1500 mm) in relationwith the total length of cells.

Standard stands for horizontal cells :

Length of the stand is determined bythe combination of 5 differentlongitudinal beams (Length 600 mm,750, 900, 1200 and 1500 mm) in relationwith the total length of cells.

Caution : Take into account the in-between pillars.

5 - General recommendations- Do not wear clothing in synthetic materials, to avoid

the generation of static potentials.

- Discharge any possible static electricity from clothesby touching an earth connected part.

- Handle the battery cells with special implementsprovided (never lift the cells by their terminals).

- Use insulated tools.

- Place the cells beginning with the least accessiblerows, spacing the cells as shown in the figure.

- Always ensure that the arrow on the cell lid ispointing upward if the cell is placed in thehorizontal position.

- Consult the drawing for the correct position of thecell poles (positive = red washer, negative = bluewasher).

- Before attaching the inter-cell flexible cables, checkthat all terminals are in the correct position.

- The battery cells are connected in series, that is witha positive pole connected to a negative pole.

- Clean the cells with nothing other than a dampenedcotton 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 - SafetyAll installation and ventilation must comply with thecurrent regulations and norms

(In France : norm NFC15-100)

Batteries must be installed in accordance with EN 50272- 2standard

7 - StandardsThe OPzV range complies with the international standard :IEC 896-2

Classified as “long life” according to the EUROBAT Guide1999

Hawker production facilities worlwide are certified toISO 9001

Low ventilation requirement according to EN 50272-2

The OPzV conforms to draft of DIN standard 40742

4 - Connecting of the cellsin series :

The number of cells in series will determine the totalfloat voltage :

U = V x N

U = total float voltage V = float voltage for one cellN = number of cells

In parallel :

OPzV cells of the same ampere hour rating may beconnected in parallel to give higher currentcapability.This connection in parallel will be preferablycarried out through an equipotential wiring for an equalcurrent distribution in each string.

These is no technical reason for limiting the number ofstrings but for practical installation reasons, it isrecommended not to exceed 4 strings in parallelespecially if the battery is used in high discharge rates(standby time lower than 1 hour.).

1 - Calculating the storage timeThe storage time is indicated on the battery lid. This takesinto account the shipping time of equipment, frequentlyquite lengthy (in the case of exports in particular).

2 - Storage conditionsThe battery should be stored away from any moisture orsource of heat.

3 - Storage timesThe self-discharge of OPzV batteries as a function oftemperatures is as follows :

In order to ensure that the battery can be charged easilyafter a long period of storage, it is recommended thatbatteries should not be stored fore more than thefollowing periods without recharging :

Failure to comply with these recommendations maycompromise the life expectancy of the battery.

4 - Recharging stored batteriesThe batteries should be recharged at the float chargevoltage to suit the temperature (2.23 volts at 20 °C percell for example) with a current limit of 0.4 C10 and for aminimum period of 96 hours.

The battery will be charged when the charging currenthas remained constant for a period of 3 hours.

5 - State of chargeThe battery state of charge can be determinedapproximately by measuring the open circuit voltageafter the battery has been at rest for a minimum of24 hours.

The necessity of a refreshing charge can also bedetermined by measuring the open circuit voltage of astored battery.

Refreshing charge is advised if the voltage drops below2.07 V/cell.

Before bringing them into service, the batteries must becharged at a constant regulated voltage to match

the prevailing temperature, for a minimum period of48 hours.

VII/ Commissioning

- Every month, check the total floating voltage at thebattery terminals.It should be N x 2.23 volts at atemperature of 20 °C, where N is the number of cells inthe battery.

- Once each year, effect a reading of the voltage of cellsconstituting the battery.

- A difference of plus or minus 2.5 % between theseindividual floating voltages and the average voltagemay be observed. This is due to the gas recombinationprocess.

- A check on capacity ( independent operation on load)can be performed once a year.

SafetyWhen carrying out any work on the battery, theapplicable safety standards should be followed.

Note : Keep a logbook battery in which the measuredvalues can be noted as well as power cuts, dischargetests( current, time, T°…) etc.

The main factors causing reductionin the life expectancy of OPzV cells- Deep discharges

- Poor regulation of the float voltage

- Poor quality (smoothing) of the charging current

- High ambient temperatures
