SRA/SRA LT/SRA HT Ni-Cd Batteries
Batteries not equipped with a water
■
filling system (typical frequency of
topping-up is every 6 months):
No electrolyte level measurement is
necessary if you use a Saft cell-topper,
which allows the correct level to be
obtained by a simple nozzle setting.
See nozzle lengths in Table A.
If a cell-topper is not available, the
electrolyte level must be measured.
Insert a transparent glass or plastic tube
(alkali resistant, 5 to 6 mm in diameter)
vertically into the cell vent until it touches
the top of the plates. Close the top
end of the tube by putting a finger on
it and remove it from the cell.
The height of the liquid in the tube
indicates the electrolyte level.

Batteries equipped with water filling
■
system (typical frequency of topping-up
is every 12 months):
• Remove transport seals and connect
hydraulic tubing between cells up to a
maximum of 50 cells.
• Make sure that the tubes are
completely inserted for a good seal.
• The hydraulic connection of cells must
be in parallel to the electrical
connection, in order to avoid voltage
differences of more than 1.2 V between
two hydraulically connected cells.
• The hydraulic connection must be
horizontal in order to avoid siphoning.
• The water filling circuit output must not
be too close to electrical equipment,
electrical circuit, and metallic structure.
• Water filling circuit input must be
connected to the self-closing inlet.
• Topping-up can be performed by gravity
or using adapted pump with a flow rate
of 0.7 l/min at a relative pressure of
0.3 bar maximum.
7. Periodic maintenance
Maintenance operations (not including
■
the topping-up operation):
Periodic maintenance should be carried
out at least every 5 years.

For detailed maintenance, please refer to
the maintenance manual of the battery.
• Keep the battery clean using only water.
Do not use a wire brush or solvents of
any kind. Vent plugs can be rinsed in
clean water.
• Check the torque of all terminal screws.
Coat with grease or neutral vaseline all
the terminal nuts and cell connectors.
• Check charger settings. It is very
important that the recommended
charging voltage remains unchanged.

High water consumption of the battery
is usually caused by improper voltage
setting of the charger.
8. Changing electrolyte
It is not necessary to change the
electrolyte during the life time of the cells.
9. Environment
To protect the environment all used
batteries must be recycled. Contact your
local Saft representative for information.
