3-1. Definitions
WARNING: WARNINGS ADVISE TO USE OF MATERIALS, PROCEDURES, OR LIMITS, WHICH MUST BE FOLLOWED
         PRECISELY TO AVOID PERSONAL INJURIES, OR EFFECT SAFETY OF FLIGHT.
CAUTION: CAUTIONS CALL ATTENTION TO PROCEDURES WHICH MUST BE FOLLOWED TO AVOID DAMAGE TO
         EQUIPMENT OR PARTS.
NOTE: Notes call attention to procedures which make the job easier.
4. Safety
CAUTION: EXCEPT FOR THOSE STEPS THAT REQUIRE THE BATTERY TO BE CHARGED, DO ALL STEPS ON DIS-
         CHARGED BATTERIES (REFER TO Residual discharge AND Cell shorting PARAGRAPH) TO AVOID THE POS-
         SIBILITY OF ELECTRIC SHOCK. TIGHTEN VENT-VALVES BEFORE THE START OF THE DISCHARGE.
         BATTERY CELLS DELIVER VERY HIGH CURRENT WHEN SHORT-CIRCUITED. BE CAREFUL. REMOVE
         RINGS, WATCHES, NECKLACES, METALLIC BELTS OR OTHER JEWELRY TO AVOID ELECTRIC SHOCK.
CAUTION: DO NOT TILT THE BATTERY WHILE DOING MAINTENANCE, ANY CONTACT OF SKIN WITH ELECTROLYTE
         CAN CAUSE SEVERE BURNS.
Local safety regulations should be followed as safety regulations are country-dependent.
There are three types of risks:
4-1. Physical
Handling: the batteries are heavy. Use proper technique when lifting heavy loads. Bend your legs and not your back.
Wear protective shoes.
4-2. Electrical
Do not wear rings, watches, chains, belt buckles, necklaces or any other conductive objects.
Use insulated tools.
4-3. Chemical
Electrolyte is very corrosive and can damage the skin. Use proper personal protective equipment (PPE) such as gloves and
an apron. If it touches the skin, flush affected area with large quantities of water. After flushing begins, remove all contaminated
clothing.
Electrolyte is very dangerous to the eyes, use protective goggles. If the electrolyte comes in contact with the eyes, flush with
water for 15 to 30 minutes and get immediate medical aid.
Saft recommends the use of an amphoteric solution (both acidic and basic behavior) and chelator (able to trap cations as a
chelate complex) to neutralize electrolyte according to the local regulation.

OPERATING AND MAINTENANCE MANUAL
INTRODUCTION
5. Aircraft conversions
Saft Ni-Cd aircraft batteries come in a wide variety of configurations that are approved for installation on selected aircraft. When
replacing a lead-acid battery with a Saft Ni-Cd aircraft battery, it is vitally important to clean all mounting and holding fixtures
in the aircraft before installation. All traces of acid and salt should be removed by washing with a neutralizing agent such as
sodium bicarbonate (baking soda) in water. When the area has been fully cleaned and prepared, paint the surface with an al-
kaline resistant paint. This preparation makes sure that your new Saft battery will not be harmed by sulfuric acid residue.
6. Ground applications
Saft batteries can be used in ground applications for starting gas turbine generators, powering ground mobile equipment, or in
shop testing equipment. The same principles used in flight operations apply when the battery is used in ground applications.
Ventilation 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.
7. Placing a new battery in service - initial commissioning
NOTE: Whether or not the battery has been subject to disassembly and reassembly, before to issue in service and
      installation certificate, check the tightness of all upper nuts / screws to verify that torque values correspond
      with those specified (refer to chapter Nut tightness).
Before installation of the battery into the aircraft for service:
   - If initial commissioning is performed within 12 months then do Visual inspection, Insulation check, Nut tightness, Charge,
     Adjust electrolyte level, and repeat Insulation check.
   - If initial commissioning is performed after 12 months, do Charge and Regular check.
   - Starting date for this period is the date of manufacturing (DMF).
8. Battery ratings capacity
Ni-Cd batteries are rated in terms of capacity in ampere-hours (Ah) (rated capacity).
American Standard AS8033 defines capacity as, “The dis-chargeable ampere-hours (Ah) available from a fully charged
cell/battery at any specified discharge rate/temperature condition.”
Other definitions for battery ratings can be found in EN2570, IEC 60952, and RTCA DO293A.
A battery rated for 1C1 Ah indicates that the battery is rated at a value based upon a discharge time of 1 hour at +23 °C  3 °C
(+73.4 °F  5.4 °F) when new.
A typical discharge curve for Saft VHP type cells can be found in figure INTRO-1 - Discharge curve for VHP type cells (20 each
cells in series under 1C1 and

9. Regulation
9-1. Recycling
All batteries eventually lose their ability to perform and are eligible for scrapping and recycling. All Saft batteries bear a recycling
label as illustrated in Figure INTRO-2 - Universal recycling symbols.
Saft takes environmental matters seriously and advocates proper recycling of Ni-Cd batteries and their components. To that
end, Saft coordinate with recycling facilities worldwide.
Ni-Cd 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 location.
The nearest recycling collection point can be found on https://saft.com/en/sustainability. A document containing a list of Bring

1-1. Batteries
NOTE: The item numbers are those of IPL figure 10001 - Ni-Cd aircraft battery.
Each Saft Ni-Cd battery, as pictured in Figure 1 - Nickel-Cadmium aircraft battery, consists of a metallic box assembly (020),
usually stainless steel, plastic-coated steel, painted steel or titanium, containing a number of individual cell assemblies (100).
These cells are connected in series to obtain a specified voltage, usually 12 or 24 volts nominal. Individual cells are enclosed
in a polyamide container that provides insulation, allowing them to be fitted side-by-side in the battery box. Cells are intercon-
nected with rigid, highly conductive, nickel-plated copper links (030 to 095). Each link is held in position by spring washers (120)
and nickel-plated copper nuts (or screws) (110 and 115) on the cells’ terminals (or nickel-plated steel bolts for internally thread-
ed terminals). Inside the battery box assembly, individual cells are held in position by a liner-spacer kit (200) and a cover com-
plete (010). Each battery is designed with appropriate ventilation to allow the escape of gases produced during an overcharge
condition.
                                                                               24-30-99                                PAGE 1

2. Operation
2-1. Climatic requirement
Although Saft Ni-Cd batteries are capable of operating in a wide temperature range from -40°C (-40°F) to +71°C (+160°F),
optimum performance is achieved between +5°C (+41°F) and +45°C (+113°F). Charging is inefficient at temperatures below
-30°C (-22°F) and is not recommended above +57°C (+135°F). Charging must be stopped at temperatures above +71°C
(+160°F).
Unless otherwise stated, charge and discharge testing should be done when:
   - The battery temperature is between +15°C (+59°F) and +35°C (+95°F).
   - Pressure 750 hPa to 1060 hPa (22.15 in.Hg to 31.3 in.Hg).
   - Relative humidity < 85%.
2-2. Maintenance
All maintenance, including charging, discharging, should be done specifically in accordance with the instructions contained in
this manual or a corresponding Component Maintenance Manual (CMM). If a CMM exists for a battery, that information will
supersede the contents of this manual and this OMM will become supplemental.
3. Charge
The charge, also named maintenance charge, is done in 2 steps:
   - Step 1: called “Charge” or “main charge”, is a constant current charge with three possible charge rates.
   - Step 2: called “overcharge” or “final charge”, is also a constant current charge with only one possible charge rate.
Other charging methods, restricted to the use of the battery, are described in following paragraphs. They cannot be used for
maintenance described in this OMM.
                                                                             24-30-99                                PAGE 3

(*) Low charge rate 0.1 C1A is suggested after cell shorting.
For example, during the main charge (step 1) at 1C1A for 1 hour:
   - If the voltage of each cell is lower than 1.57 V, then continue the charge during 15 minutes maximum (0.25 hours) or stop
     if the voltage reaches 1.57 V before 15 minutes. Then continue with the final charge (step 2).
   - If the voltage of each cell is higher than 1.57 V then continue with the final charge (step 2).

                                               INSPECTION/CHECK
1. Introduction
This chapter includes the checks, the maintenance procedures and the functional tests that must be done to use Saft batteries
in flight and on the ground.
NOTE: All (###) part identification numbers herein are IPL figure 10001 - Ni-Cd aircraft battery item numbers and are
     using hypertext facility.
2. Maintenance intervals
The aircraft manufacturer and / or operator is responsible for defining the usage and function, including maintenance intervals,
for aircraft batteries installed in its aircraft. Saft only provides recommendations that require the agreement of the aircraft man-
ufacturer and / or operator.
NOTE: Maintenance steps should be completed in a battery shop.
Saft distinguishes between three types of maintenances: periodical check, regular check and general overhaul.
3. Recording
It is very important to record the battery check values (capacity, end of charge voltage, water consumption) for each cell as
required in the battery logbook (or equivalent) for each maintenance. It is recommended that an operator tracks these mainte-
nance data in order to verify the interval is correct relative to that particular operation. This may also allow the interval to be
extended if the data justifies it.

INSPECTION/CHECK
6-1. Visual inspection
CAUTION: WORN AIRCRAFT POWER CONNECTORS AND/OR LOOSE CONNECTIONS CAN GREATLY AFFECT THE
         PERFORMANCE OF THE BATTERY. A DEFECTIVE POWER CONNECTOR CAN CAUSE OVERHEATING,
         BATTERY SELF-DISCHARGE AND LOW VOLTAGE IN SERVICE.
NOTE: Refer to TESTING AND FAULT ISOLATION for additional component level information.
Visual inspection should be done each time the battery is removed for maintenance from the equipment.
   - Remove the cover complete (010).
   - Inspect each cell assembly (100) for evidence of electrolyte leakage. If OK, pass the inspection and proceed to Light clean-
     ing. If NOT OK, identify as fail and proceed to General overhaul and replace the defective cell or part.
NOTE: Excessive salt around terminal posts indicate possible leakage from the terminal O-ring (400). During General
       overhaul, verify torque of the lower nut (115) (refer to chapter ASSEMBLY).
  - Inspect the links (030 to 095), upper nuts (110), and washers (120 and 150). If hardware has no bends, tarnish, corrosion,
    burns, or any loss of nickel plating, PASS the inspection and proceed to Light cleaning. If NOT OK, identify as FAIL and
    proceed to General overhaul and replace the defective assembly.
NOTE: Minor tarnish can be polished off with a non-metallic wire brush.
  - Inspect the power connector assembly (230). If OK and no evidence of arcing, corrosion, cracks, or cross-threaded ter-
    minals is found, PASS the inspection and proceed to Light cleaning. If NOT OK, identify as FAIL and proceed General
    overhaul and replace the defective assembly.
  - Inspect the sensor connector assembly (260). If OK, and no bent or loose pins, corrosion, cracks, faulty wire connections,
    evidence of arcing, or cracked or loose potting material is found, PASS the inspection and proceed to Light cleaning. If
    NOT OK, identify as FAIL and proceed to General overhaul and replace the defective assembly.
  - Inspect the sensor connector assembly (260) temperature sensor and heater blanket harness assembly (as applicable)
    for obvious damage. If OK, PASS the inspection and proceed to Light cleaning. If NOT OK, identify as FAIL and proceed
    to General overhaul and replace the defective assembly.
NOTE: This in no way replaces the full testing procedures found hereafter which ensure full operation of the sensor
       connector assembly (260). Any evidence of damage to the temperature sensor and/or heater blanket harness
       assembly (as applicable) requires the sensor connector assembly (260) replacement
  - Inspect the sensor connector assembly (260) thermostat assemblies (as applicable) for any damaged or loose wire con-

OPERATING AND MAINTENANCE MANUAL
INSPECTION/CHECK
Adjust the level of electrolyte, one cell at a time, using the following instructions:
   - 1. Remove the vent-valve assembly (160) (with the O-ring) with the universal vent-valve wrench (T01).
   - 2. Check the nozzle length before fitting it to the syringe (refer to paragraph Special tools for proper nozzle).
NOTE: Use a metric ruler to measure the nozzle length from its tip to the nozzle inside shoulder (surface which will
        be resting on the cell cover)
  - 3. Insert the syringe (T02) into the cell assembly (100) opening until the shoulder of the nozzle rests on the vent-valve seat
    per figure 5002 - Position of syringe in cell vent seat.
M8 MS
   - 4. Withdraw the plunger and check for any liquid in the syringe. Any excess liquid in the cell will be drawn into the syringe
     until the electrolyte is level with the end of the nozzle. This is the correct level for the electrolyte.
     If the liquid level is too low, the syringe will remain empty, indicating that the end of the syringe nozzle did not reach the
     liquid in the cell. In this case, replenish low electrolyte using distilled water M01 according to steps 5 to 8.
   - 5. Draw 5 cm3 (0.3 in3) of the distilled water M01 into the syringe and inject it into the cell.
   - 6. With the syringe nozzle remaining on the vent-valve assembly (160) seat, slowly withdraw the plunger in the syringe
     one time again.
   - 7. If the syringe remains empty, repeat steps 5 and 6, counting the total volume required to achieve the correct level. Re-
     cord the amount of water added to each cell on the maintenance record.
   - 8. At the point in step 6 when some excess liquid is drawn into the syringe, the correct level for that cell has been reached.
     Expel the excess liquid into a separate container for disposal. Do not re-use the liquid removed from cells. Check with
     local authorities for proper disposal of hazardous waste.

8-4. Vent-valve test
WARNING: VENT-VALVES SHOULD BE CLEANED BEFORE TESTING (REFER TO Vent-valves CLEANING).
CAUTION: WHEN REPLACING O-RINGS, CARE MUST BE TAKEN TO AVOID DAMAGING VENT-VALVES.
NOTE: The vent-valve test is not necessary if the full set of used vent-valve is replaced by new ones each year during
      the General overhaul or when there is evidence of electrolyte overflow.
NOTE: If the vent-valve does not open during the test, increase the pressure slowly until the vent-valve opens (one
      time, to 1.4 bar (20 psi) maximum) to ensure functionality, then repeat the full test.
This test should be done while the battery is on charge.
Check the operation of the vent-valve assembly as follows:
   - Install the vent-valve assembly (160) with its O-ring finger tight into the vent-valve adapter (T05*) of the pressure test fix-
     ture.
   - Tighten the vent-valve assembly (160) according to FITS AND CLEARANCES.
   - Immerse the vent-valve assembly (160) in water.
   - Slowly raise the air pressure.
   - Test each vent-valve assembly (160) according to table 5002 - Vent-valve test.
   - If a test fails, replace vent-valve and/or o-ring as applicable.
                              Test                                                             Check
O-ring                                                             No distortion, split, cracks, or corrosion
Air pressure < 0.14 bar (2 psi)                                    Vent-valve is closed (no bubbles observed)
0.14 bar (2 psi) < air pressure < 0.7 bar (10 psi)                 Vent-valve opens (bubbles observed)

OPERATING AND MAINTENANCE MANUAL
1. Description
The Illustrated Parts List (IPL) contains a list and illustrations of the assemblies and detailed parts of the unit in disassembly
sequence.
Table 10001 - Illustrated Parts List (IPL) generic example can be used to construct an illustrated parts list for a battery.
To determine the part number of a given part, refer to the provided illustration (figure 10001 - Ni-Cd aircraft battery) and refer
to the item number describing the part. The item number is used to locate the row for the respective part in table 10001 - Illus-
trated Parts List (IPL) generic example.
To find the part number for a specific part, refer to the column Reference page and navigate the hyperlinked page numbers to
find the part number specific for that item number of the battery.
NOTE: 6 digit part numbers formatted as ###### are sold under supplier cage code F6177. 9 digit part numbers for-
      matted as ######-### are sold under supplier cage code 09052.
NOTE: Saft manufactures, warrants and accepts liability for the spare parts and components it provides to customers
      for use on/in components and products manufactured by Saft.
NOTE: Saft will not accept responsibility for any replacement or substitute part(s) of any kind other than those sup-
      plied by Saft and its authorized distributors.
NOTE: Saft and all affiliate companies within Saft group, indemnifies and holds itself harmless by virtue this warning
      from any performance claim or expectation, and any failure and/or consequence thereof associated with the
      functionality and performance of its products when/if non-Saft replacement or substitute parts, of any kind,
      are used on/in Saft products.
NOTE: The use of non-Saft replacement parts, of any kind, on/in components or products manufactured by Saft will
         VOID ANY and ALL WARRANTIES.
Blank rows in the Quantity per assembly column are specific to each battery. Fill these rows in with information specific to the
battery.
NOTE: Not all batteries are equipped with every part listed in the table 10001 - Illustrated Parts List (IPL) generic example.
      If a battery is not equipped with a specific part, the row for that part can be crossed out or ignored.
Numbered parts of assemblies and sub-assemblies included in the list but not illustrated are identified by a hyphen (-) preced-
ing the item number.
The attaching parts are shown directly after the assembly of the part thereof. They are listed under the same indent number as
the item they are attached to, are identified by the words “Attaching Parts” and are followed by three asterisks.
The manufacturer's code or the abbreviation NP (not procurable) are placed at the extreme right- hand side of the first line of
the parts list column.
Nomenclature: the nomenclature is given with an indenture, to show how the parts and the assemblies are related to the overall
assembly. These are the details:

2. Storage
2-1. Inactive long-term storage
2-1-1. Procedure
Before placing a battery into inactive long-term storage, the battery must successfully complete Regular check or General over-
haul and be in a discharged condition (refer to Residual discharge and Cell shorting). There is no need of maintenance oper-
ation during the storage period. It is not necessary to short circuit the battery. No revalidation is required during the storage.
NOTE: If Climatic conditions are met and the packaging protects the battery from mechanical damages, environmen-
      tal contaminants (i.e.: dirt, dust, vibrations, or corrosive atmosphere), and is airtight, then a 10 year storage
      period is allowed (if not airtight, a 2 year storage period is allowed).
The batteries are stored in a normal vertical position as described in paragraphs Storage room and Climatic conditions.
2-1-2. Action at the end of long-term storage
For batteries under long-term storage and before installation of the battery into the aircraft for service:
   - If storage time is less than or equal to 12 months, then do Visual inspection, Insulation check, Nut tightness, Charge, Ad-
     just electrolyte level, and repeat Insulation check.
   - If storage time is over 12 months do Charge followed by Regular check.

2-2-2-1. Definitions
   - The Inactive standby storage period is a maximum 90 days (3 months) for average room temperature < +23 °C (+73.4 °F).
   - Total standby storage duration is 9 standby storage periods or 810 days (27 months).
2-2-2-2. Examples of standby storage period
   - 24 days at an average room temperature of +30 °C (+86 °F).
   - 60 days at an average room temperature of +25 °C (+77 °F).
2-2-3. Refresh charge
The Inactive standby storage period can be prolonged by applying refresh charge (at the end of the period). The refresh charge
is defined as a short charge at 0.1C1A, 0.5C1A, or 1C1A until the voltage reaches the values given in the Table 15002 - Inactive
standby storage below.
The battery can receive the refresh charge two (2) times maximum during each standby storage period. The time necessary
to reach the required voltage should be very short. Do not overcharge at 0.1C1A for 4 hours.
2-2-4. Action at the end of standby storage periods (refer to figure 15002 - Inactive standby storage)
NOTE: During any standby storage periods the battery is serviceable.

4. Transportation procedure
The battery is normally discharged before packing. If it is necessary to transport a charged battery, make sure that the output
terminals are protected against short circuit.
The battery should be packed vertically in its original container. If the original container is not available, the international and/
or local packaging regulations applicable to the mode of transport and destination must be followed.
According to the IATA / IMDG dangerous goods regulations, Saft ships all existing Ni-Cd batteries or cells for aircraft under the
classification UN2795 (wet, filled with alkali).
