GeneralThis manual provides the information necessary for an experienced shop technician to maintain Saft nickel-cadmium describes construction of the battery, as well as techniques used to operate, maintain, repair, overhaul, and generally carefor the battery. Following these instructions will enhance the ability to obtain optimum performance and maximum life from Saftbatteries. All aircraft batteries require checking and maintenance in order to make sure they are safe when installed and they performtheir required functions especially in emergency conditions on board the aircraft. Maintenance checks also permit any prob-lems to be identified and corrected. The maintenance interval is the period for which correct operation is assured with a lowprobability of failure and allows high levels of MTBUR and MTBF to be achieved. Apart from the question of safety, the avoid-ance of failure on board the aircraft, with consequent costly impact on delays, reduces operational costs. Every effort has been made to provide complete and accurate instructions. If a situation should arise that is not adequatelydescribed in this manual, please contact Saft via the internet at or at one of the following addresses:2. WebsiteAll Saft technical documentation, distributors and repair shops can be found at DefinitionsWarnings call attention to use of materials, procedures, or limits, which must be followed precisely to avoid injury to persons. Cautions call attention to procedures which must be followed to avoid damage to equipment.

When re-placing a lead-acid battery with a Saft nickel-cadmium aircraft battery, it is vitally important to clean all mounting and holdingfixtures in the aircraft prior to installation. All traces of acid and salt should be removed by washing with a neutralizing agentsuch as sodium bicarbonate (baking soda) in water. Once the area has been fully cleaned and prepared, the surface shouldbe painted with an alkaline resistant paint. This preparation should ensure that your new Saft battery will not be harmed bysulfuric acid Ground ApplicationsYour Saft battery can be used in such ground applications as starting gas turbine generators, ground mobile equipment, or inshop testing equipment. The same principles used in flight operations apply when the battery is used in ground of the battery during ground use can be accomplished through a ventilation system or by simply removing the cover(only in a well-ventilated area). Check with your local authorities for regulations in effect for your Placing a new battery in service - initial commissioningNOTE: Whether or not the battery has been subject to disassembly and reassembly, before its issue to service andinstallation, the tightness of all connector nuts / screws must be checked to verify that torque values corre-spond with those batteries are shipped discharged. A visual inspection, torque check, charge procedure, electrolyte check, and insulationtest should be done prior to the battery being placed into the aircraft for service. Refer to the INSPECTION/CHECK the battery has been stored for longer than 3 months, refer to Servicing after discharged storageComponent Maintenance Manual275824-38-51 Page INTRO-3Apr 08/20138. Battery Ratings8-1. CapacityNickel-cadmium batteries are rated in terms of capacity in ampere-hours (Ah) (rated capacity). Capacity is the quantity of electricity, usually expressed as ampere-hours (Ah) available from a cell/battery. The rated capacityof aircraft batteries is defined according to international standards (EN2570, IEC 60952 and RTCA DO 293) under specific con-ditions for a fully charged battery. A battery rated for 1C1Ah indicates that the battery is rated at a value based upon a discharge time of 1 hour at 23 C 3 C( F F). 9. RecyclingAll batteries eventually lose their ability to perform and are eligible for scrap and recycling. Saft takes environmental mattersseriously and advocates proper recycling of nickel-cadmium batteries and their components. To that end, Saft operates recy-cling facilities in both Europe and North batteries contain nickel, cadmium, and potassium hydroxide and should be disposed of properly. In all cases,rely on local and national regulations for proper battery disposal and/or shipping to an appropriate recycling INTRO-1 Universal Recycling SymbolsYou can find the nearest recycling collection point on our website at End of life cellsEASA regulations Part 145 , require that end of life cells must be disposed of in a manner that does not allow them to be re-turned to service. The following procedure provides a means of complying with these regulations. While other authority requirements (such as FAA) may be less explicit, Saft recommends that the following procedures beadopted in order to ensure that end of life cells cannot be re-used:- Ensure that appropriate protective measures (refer to Safety paragraph) and MSDS are Ensure that the cell is fully discharged (refer to Cell shorting paragraph)- Put one of the terminals from the cell between the two sides of a bench vice and bend until the terminal breaks. In theevent of electrolyte leakage, ensure that appropriate clean up measures as described in the MSDS are Dispose of the cell in accordance with applicable transport, health and safety and recycling regulations (Refer to Recyclingparagraph).Component Maintenance Manual275824-38-51 Page INTRO-4Apr 08/201311.

Introduction1-1. GeneralThis chapter includes the checks, the maintenance procedures and the functional tests that must be done to use Saft batteriesin flight and on the ground. NOTE: All ( ) part identification numbers herein are IPL Fig. 1 item Maintenance intervalsThe aircraft manufacturer is responsible for defining the usage and function for aircraft batteries installed in its aircraft. NOTE: Maintenance steps must be completed in a battery shop. Saft distinguishes between three types of maintenance2-1. Periodical checkThe periodical check consists essentially of voltage and insulation checks, discharge of residual capacity and charge with elec-trolyte level adjustment. The main purpose of this periodical check is to replace water which is consumed by electrolysis duringbattery overcharge. It is normally applied between regular checks but can be omitted if the water consumption measured atthe regular check is within allowable limits. 2-2. Regular checkThe regular check is the same as the periodical check except that the battery is also deep discharged ('balancing'), followedby a capacity check cycle. 2-3. General overhaulThe general overhaul is the same as the regular check except that the battery is also disassembled and thoroughly cleanedand RecordingIt is very important to record the battery check values (capacity, end of charge voltage, water consumption) as required in thebattery logbook for each maintenance. It is recommended that an operator tracks these maintenance data in order to verifythe interval is correct relative to that particular operation. These data may also allow the interval to be extended, with the agree-ment of the competent authorities, if the data justify it . 4.

If there is salt or electrolyte traces do a Generaloverhaul. Excessive salts around a terminal post indicates possible leakage from the terminal O-ring. Verify the torqueof the lower nut (refer to chapter ASSEMBLY).- Inspect the links (270 to 310) and all upper nuts (250), and washers (360 and 380). The hardware should be free ofbends, tarnish, corrosion, burns, or any loss of nickel plating. Minor tarnish can be polished off with a fine wire hardware should be Check the connector (200) for evidence of arcing, corrosion, cracks, or cross-threaded terminals. Replace the defec-tive : Worn aircraft connectors and/or loose connections can greatly affect the performance of the battery. A de-fective connector (200) can cause battery self-discharge as well as low voltage in Inspect the electrical connector for bent or loose pins, corrosion, cracks, faulty wire connections, evidence of arcing,or cracked or loose potting Inspect the battery box (020) and cover assembly (050) for any damage. Minor dents may be repaired with a smallrubber mallet. Ensure the cover gasket (070), if applicable, is undamaged and fully secured to the cover assembly(060).6-2. Insulation checkA breakdown in electrical insulation between the cells (320) and the battery box (020) will result in a leakage current, whichover time will discharge the battery. The most common cause for the loss of insulation is the leakage of electrolyte from thecells (320) that acts as a conductor between the cells and the battery box (020). Because leakage current can affect batteryperformance, it is necessary that it be kept to a a completely assembled battery, use a megohmmeter, set to 250 V DC, to mea-sure the insulation resistance between the positive terminal of each cell (320) andthe battery box (020).Refer to the table below for the acceptance K 2 M 10 M Acceptable but cleaning is recom-mendedMust be a General OverhaulCheck the cause( )Acceptable for in ser-vice batteryMandatory level of insulation for new or in service battery after cleaningComponent Maintenance Manual275824-38-51 Page 5004Apr 08/20136-3.

Polarization testCharge the battery at A for the battery in open circuit for 1 the open circuit voltage of each cell. If any cell is zero (0) V or negative polarity, do a General overhaul. If all cellsare above zero (0) V, continue with maintenance as Residual dischargeDischarge the battery at the 23 A or A rate until each cell in the battery is discharged to volt or Adjust electrolyte levelCaution: Using anything other than distilled or deionized water in nickel-cadmium cells will cause electrolyte contam-ination and take appropriate precautions to prevent any foreign substances from entering the cell. Anything other than distilled ordeionized water that enters the cells will cause electrolyte contamination and will affect overall performance. The amount of time that the vent-valves are removed from the cell for maintenance should be limited to prevent as much airas possible from entering the cell. Carbon dioxide in the air will combine with the electrolyte to form potassium carbonate. Po-tassium carbonate will increase the internal resistance of the cells and thus decrease the performance at low temperatures andduring high rate discharges. Always ensure that the vent-valves are properly secured while the battery is in level adjustment is to be done during the last 15-30 minutes of the 4 hours overcharge at A rate of : Take care not to tilt cells while vent-valves are loosened or removed. Contact of electrolyte with skin cancause burns. If contact occurs, flush area with large amounts of water. Electrolyte in the eyes is very with water and contact a doctor : The battery must be fully charged before adjusting the electrolyte only distilled or deionized water (see chapter SPECIAL TOOLS, FIXTURES, EQUIPMENT AND CONSUM-ABLES). Do not re-use water removed from cells. The quantity (in cm3) required to level the first cell will serve as a guide for requirements of the remaining cellsbut the amount of water required for each cell can vary, so carry out this check on a cell by cell basis. Each cellmust be leveled individually. If the quantity of water added per cell is above 80% of the electrolyte water volumeshown in the specification tables (60 cm3 ( in3)), check the charging system. If it is functioning properly,shorten the time period between servicing. In no case must the water consumption exceeed 60 cm3 ( in3).Adjust the level of electrolyte, one cell at a time, using the following instructions: - 1. Remove the vent-valves (325) with the vent-valve wrench (T01)- 2. Check the nozzle length at 20 mm before fitting it to the syringeComponent Maintenance Manual275824-38-51 Page 5005Apr 08/2013- 3.

Withdraw the plunger and check for any liquid in the excess liquid in the cell will be drawn into the syringe until the electrolyte is level with the end of the nozzle. Thisis the correct level for the the liquid level is too low, the syringe will remain empty, indicating that the end of the syringe nozzle did not reachthe liquid in the cell. In this case, replenish low electrolyte:.- 5. Draw 5 cm3 of the distilled water (M01) into the syringe and inject it into the 6. With the syringe nozzle remaining on the vent-valve (325) seat, slowly withdraw the plunger in the 7. If the syringe remains empty, repeat steps 5 and 6, counting the number of 5 cm3 injections required to achieve thecorrect level. Record the amount of water added to each cell on the maintenance 8. At the point in step 6 when some excess liquid is drawn into the syringe, the correct level for that cell has beenreached. Expel the excess liquid into a separate container for disposal. Do not re-use the liquid removed from with local authorities for proper disposal of hazardous Supplementary testAt the end of complete charge, continue to charge for 5 h at A Measure the voltage of the individual cell voltages every 30 min.

However, occasional excursion into the range of -60 C to +60 C (-76 F to +140 F) is Storage procedure2-1. Short term storage2-1-1. Preparation of the battery for short term storageService the battery as scheduled (periodical check, regular check or general overhaul check). The battery is fully charged atthis lubricate the nuts, the links, and all the components that can be damaged by atmospheric corrosion with the battery in its usual vertical Periodic refresh chargeThe battery can stay in storage for a period shorter than thetime necessary to reach 80% of capacity. This duration de-pends on storage temperature according to Figure 15001 :for instance 60 days at 25 C, with a maximum of 90 the storage has to be extended beyond this duration, per-form a refresh charge at the end of the period. The refreshcharge is defined as a short charge until the battery voltagereaches the value given in the table belowIf the maximum duration is exceeded, do a Regular check .After the Regular check, the battery can be refreshed againaccording to the refresh charge battery can be refreshed 2 times allowing a maximumstorage duration of 3 periods. For example at 25 C, the stor-age can be extended to 180 Placing the battery back to serviceThe short term storage procedure can be interrupted at any time to install the battery back onboard an A/C without the needof further of chargevoltageMaximum A30 V2 A31 V24 min23 V12 min40 C35 C30 C25 C20 C5 CAVAILABLE CAPACITY (%C1Ah)REST TIME (days)607080901000102030405060708090CHAR GE RETENTIONAircraft Ni-Cd batteryFigure 15001 Short term storageComponent Maintenance Manual275824-38-51 Page 15002Apr 08/20132-2. Long term storage (discharged battery)Caution: Saft Ni-Cd batteries may be stored in temperatures ranging from - 60 C (67 F) to + 60 C (+ 140 F) for shortperiods of time without harming the standard cardboard packaging is considered unsealed and allows 2 years of storage under the above maintenance operation needs to be done during the storage period. Lead batteries must be stored in a different OperationsDischarge to 20 greasing of cell in a storage ConditionsThe battery should be stored filled and storage life is 10 years, if using the following conditions:- Sealed Temperature: + 20 C 15 C (68 F 27 F).- Humidity: < 70 %.- Normal vertical Isolated from detrimental agents: dirt, dust, humidity, vibration, corrosive PackagingThe batteries and cells are usually put in cardboard boxes. For long storage, we recommend to put them in a heavy gaugeplastic bag that is subsequently heat sealed. In this type of container, with the recommended temperature range, the batteriescan be kept for 10 Servicing after discharged storage3. Transportation procedureThe battery is normally discharged before packing. If it is necessary to transport a charged battery, make sure that the outputterminals are protected against short circuit. The battery should then be packed vertically in its original container. If the original container is not available, the internationaland/or local packaging regulations applicable to the mode of transport and destination must be to IATA/IMDG dangerous goods regulations, Nickel Cadmium aviation batteries as well as individual aviation NickelCadmium cells must be shipped under the UN 2795 classification (wet, filled with alkali) according to packing instruction 801.
