Storage (including transportation)
At stand-by period 1 or 2 there are 3 possibilities
- Do a Refresh Charge to continue 1 more stand-by period
- Or put the serviceable battery into the aircraft without any further maintenance
- Or put the battery into Inactive long term storage refer to the procedure
At 9 months and at 18 months there are 3 possibilities
- Put the serviceable battery into the aircraft without any further maintenance
- Or continue stand-by storage:
- if the temperature is < or = +30 °C: do insulation test + residual discharge + Charge + adjust elec-
trolyte level + insulation test to continue stand-by storage
- if the temperature is > 30 °C then do a Regular check to continue stand-by storage
- Or put the battery into Inactive long term storage refer to the procedure
At 27 months there are 2 possibilities
- Put the serviceable battery into the aircraft without any further maintenance
- Or do a Regular check and put the battery into Inactive long term storage refer to the procedure
3. Storage of spares
3-1. Spare Cells
Spare cells must be stored filled and discharged (in a discharged cell, the electrolyte level is not visible). It is
not necessary that they be short circuited. The vent valves must not be removed. The storage conditions are
the same as those given in para. Inactive long term storage. No maintenance operation is needed during stor-
age. Before installation in a battery, cells must be visually inspected for damage or leakage and cleaned and
repaired as necessary in accordance with the battery maintenance documentation.
3-2. Spare 0-rings, gaskets and vent valves
3-2-1. 0-rings and gaskets
6 years of storage with storage conditions from date of manufacture unless otherwise specified on the pack-
aging. They must be protected from exposure of air, light and high humidity(< 85%). Storage life depends
on temperature so it is recommended to store in a cool area (<25 °C I 77 °F). At +35 °C I 95 °F, storage life
is reduced to 5 years. Before use, 0-rings must be inspected and any showing visible signs of damage, dis-
tortion or deterioration must be discarded.
3-2-2. Vent valves with 0-rings
6 years of storage with storage conditions from date of manufacture unless otherwise specified on the pack-
aging (the limitation is due to the 0-ring). Protected from exposure of air, light and high humidity(< 85%).
Storage life depends on temperature so it is recommended to store in a sealed container (non-PVC) in a cool
area (<25 °C I 77 °F). At +35 °C I 95 °F, storage life is reduced to 5 years. Before use, 0-rings must be in-
spected. In case of visible signs of damage, deformation or deterioration, the 0-ring must be discarded.
3-2-3. other spares
Other spares, protected from external contamination (i.e. dirt, dust, dampness, vibration, corrosive atmo-
sphere) and high humidity(> 85%), may be stored for unlimited periods. Before use, they must be inspected
and any showing visible signs of damage, distortion or deterioration must be discarded.
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 then 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 I IMDG dangerous goods regulations, Saft ships all existing nickel-cadmium batteries
or cells for aircraft under the classification UN2795 (wet, filled with alkali).
