Saft SMRX-F3 User manual

Important recommendations
■ Never allow an exposed flame or
spark near the batteries,
particularly while charging.
■ Never smoke while performing any
operation on the battery.
■ For protection, wear rubber gloves,
long sleeves, and appropriate
splash goggles or face shield.
■ The electrolyte is harmful to skin
and eyes. In the event of contact
with skin or eyes, wash immediately
with plenty of water. If eyes are
affected, flush with water, and
obtain immediate medical attention.
■ Remove all rings, watches and
other items with metal parts before
working on the battery.
■ Use insulated tools.
■ Avoid static electricity and take
measures for protection against
electric shocks.
■ Discharge any possible static
electricity from clothing
and/or tools by touching an
earth-connected part "ground"
before working on the battery.
1. Receiving the shipment
Unpack the battery immediately upon
arrival. Do not overturn the package.
Transport seals are located under the
cover of the vent plug.
Make sure all items on the packing list
are included with the shipment.
SMRX-F3 batteries are usually
shipped discharged and filled with
electrolyte. Check for damage or
electrolyte spillage. Report any
irregularities to the carrier and Saft.
Remove the plastic transport seals
immediately prior to installation on the
car or any charge/discharge. The
battery must never be used electrically
while the plastic transport seal is in
place as this can cause permanent
damage.
A charged battery can be installed
immediately. Refer to Section 4 for
applicable Commissioning. Always refer
to Section 2 for Storage conditions.
2. Storage
Store the battery indoors in a dry,
clean and cool location (0°C/+ 32°F to
+ 30°C/+ 86°F).
■ Make sure that the transport seals
remain in place during storage.

Installation and operating instructions
■ Do not expose the batteries to direct
sunlight or excessive heat.
■ A battery delivered discharged and
filled may be stored for many years
before it is installed.
■ A battery delivered charged (80 %)
must not be stored more than
3 months (including transport) or at
a temperature >+ 30°C (>+ 86°F)
.
The battery is ready for immediate
use within this 3-month period. Refer
to Section 4 if stored beyond
3 months or at a temperature
>+ 30°C (>+ 86°F).
■ A battery delivered fully charged
must not be stored more than
6 weeks (including transport) or at
a temperature >+ 30°C (>+ 86°F). If
beyond 6 weeks or >+30°C (+86°F),
contact Saft.
3. Installation
Remove the transport seals and close
the vent plug.
3.1. Verify that cells are correctly
interconnected and that the battery
is properly connected to the load.
3.2. Check tightness of terminal
connecting nuts. Torque applied must be:
• Top terminal nut (M12 terminal post;
12 mm / 19 mm (1/2”) Top Nut) :
15 ± 2 N.m (11±1.5 ft.lb)
The connectors, terminal nuts,
(if supplied) must be corrosion-protected
by coating with a thin layer of neutral
vaseline or anti-corrosion oil (contact
Saft for more information).
3.3. Electrolyte
The electrolyte to be used is E10.
■ Cells delivered filled:
Check the level of electrolyte. The cells
must have a level of electrolyte above
the plates. If it is not the case, adjust
the level of electrolyte to 5 mm (0.2 in)
above the plate tops with distilled or
deionized water.
4. Commissioning
Refer to Table A for 0.2 C5 A charge
or discharge currents.
4.1. Discharged cells placed into
service immediately after delivery or
after less than one year of storage:
■ Constant current charge:
• 8 h at 0.2 C5 A
Caution: during charging, the battery
box must be open.
■ Constant potential charge:
• 1.55 V/cell for 20 h, with the
current limited to 0.2 C5 A
Charge at constant current is
recommended. The battery is ready
for use.
4.2. Discharged cells stored more
than 1 year:
a) charge 10 h at 0.2 C5 A
b) discharge at 0.2 C5 A down to
1.0 V/cell
c) charge 8 h at 0.2 C5 A
The battery is ready for use.
4.3 Charged cells (80%) shipped
and stored at temperatures
<+30°C (+86°F), less than 3 months
from date of charge:
The battery is ready for use.
4.4. Charged cells (80%) shipped
and/or stored at temperatures
>+ 30°C (>+ 86°F), and/or ≥3 months
from date of charge:
a) charge 10 h at 0.2 C5 A
b) discharge at 0.2 C5 A down to
1.0 V/cell
c) charge 8 h at 0.2 C5 A
The battery is ready for use.
5. Charging in service
5.1. Cycling application
The battery is cycled up to 20% DOD
(Depth Of Discharge) per day.
■ Single level charge:
1.45 - 1.55 V/cell at + 20°C (+ 68°F)
1.47 V/cell is recommended.
■ Two level charge:
• High level: 1.45 - 1.60 V/cell
at + 20°C (+ 68°F)
• Float level: 1.38 - 1.40 V/cell
at + 20°C (+ 68°F)
5.2. Stand-by application
Battery is on float and discharged only
in emergency situation.
■ Single level charge:
1.41 - 1.43 V/cell at + 20°C (+ 68°F)

■ Two level charge:
• High level: 1.43 - 1.50 V/cell
at + 20°C (+ 68°F)
• Float level: 1.38 - 1.40 V/cell
at + 20°C (+ 68°F)
For use at temperature outside +10°C
to +30°C (+50°F to +86°F), the charge
voltage correcting factor is:
• – 2 mV/°C/cell (– 1.1 mV/°F/cell)
if charged voltage <1.45 V/cell at
+ 20°C (+ 68°F)
• – 3 mV/°C/cell (– 1.7 mV/°F/cell)
if charged voltage between 1.45
and 1.55 V/cell at + 20°C (+ 68°F)
For higher charging voltages,
consult Saft.
To minimise the water usage,
Saft recommends the use of low
charging voltages.
6. Topping-up
No electrolyte level measurement is
required if a Saft Celltopper Plus is
used which allows the correct level to
be obtained by a simple nozzle setting
when fitted with the correct spacer
tube. Refer to Table B for cell type
and corresponding spacer tube type.
If a filling pistol is not available, a clean
plastic filling bottle can be used for
topping-up. Do not fill above the
maximum (upper line) level. All topping-
up equipment shall be dedicated to
Ni-Cd batteries.
7. Periodic maintenance
Periodic maintenance should be
carried out every two years or as
required.
■ 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 when dirty.
■ Check the electrolyte level. Never
let the level fall below the minimum
(lower line) level. Use only distilled
or deionized water for topping-up.
■ Frequency of topping-up must be
determined for each battery.
It depends on charging voltage,
temperature and actual utilization
of the battery. Refer to Section 6
concerning topping-up.
■ Check torque of all upper nuts
(if supplied).
■ Apply a thin layer of neutral Vaseline
or anti-corrosion coating agreed by
Saft to all connectors and terminal
nuts (if applicable).
■ 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
Due to the sintered electrode / plastic
bonded technology, it is not necessary
to change the electrolyte during the
life-time of the cell(s).
9. Battery service and recycling
Contact your Saft representative
concerning battery testing.
Saft America Inc. is licensed to receive
and recycle spent batteries.
To protect the environment all used
batteries must be recycled.
