6. Charging in service
On-board application (railway)
I
The battery is cycled up to 20%
Depth Of Discharge (DOD) per day.
•
Single level charge:
1.45 to 1.55 V/cell at +20°C (+68°F)
1.47 V/cell is recommended
I
Stationary application
The battery is on float and discharged
only in case of emergency.
•
Single level charge:
1.41 to 1.43 V/cell at +20°C (+68°F)
•
Dual level charge:
- High level: 1.43 to 1.50 V/cell
at +20°C (+68°F)
- Float level: 1.38 to 1.40 V/cell
at +20°C (+68°F)
Voltage compensation

to +86°F), the charge voltage
correcting factor is:
– 3 mV/°C/cell (– 1.7 mV/°F/cell)
if the charging voltage is ≥ 1.45 V
at +20°C (+68°F)
For any other charging voltages,
consult Saft.
To minimise the water
consumption, Saft recommends
the use of low charging voltage.
7. Topping-up
Before topping up operation, the
water filling circuit of the battery
must be checked for tightness (no
leaks) using a pressure test (a kit
may be supplied by SAFT).
Use only distilled and deionized
water for topping-up.
Connect distilled water tank to the
self-closing inlet.
Topping-up is completed when an
excess of 1 litre of water is measured
at the outlet of the water filling circuit.
Topping-up can be performed by
Saft's gravity kit or by using Saft's
water filling stations.
8. Periodic maintenance
In addition to the topping-up,
a periodic maintenance shall be
carried out at least every 5 years.
For detailed maintenance, please
refer to the maintenance manual of
the battery.
I
Keep the battery clean using only
water. Do not use a wire brush or
solvents of any kind.
I
Check torque of all terminal
screws. Coat with grease approved
by Saft or neutral vaseline all
terminal screws and connections.
I
Check charger settings. It is very
important that the recommended
charging voltage remains
unchanged. High water
consumption by the battery is
usually caused by improper voltage
setting of the charger.

I
Frequency of topping-up must be
determined for each battery.
Topping-up shall be performed
every 6 months during the first
year in order to determine the
ideal topping-up interval (generally
every 2 years). It depends on the
charging voltage and actual use of
the battery. Refer to section 7
concerning topping-up.
9. No change of electrolyte
required
Thanks to the sintered/plastic
bonded electrode technology, it is not
necessary to change the electrolyte
during the life of the battery.
10. Recycling
To protect the environment, all used
batteries must be recycled. Contact
your local Saft representative for
information.
