Installation and operating instructions
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.
The battery is normally shipped filled and
ready for installation.
• Make sure all items have been received by
comparing with the packing list.
• Check for damage or electrolyte spillage.
Report any irregularities to the carrier and to
Saft.
• Remove the plastic transport seals. The
battery must never be used electrically with
the plastic transport seal in place as this can
cause permanent damage.
The battery is ready for installation.
2. Storage
Store the battery indoors in a dry, clean, cool
location (0°C to +30°C / +32°F to +86°F).
• Make sure that the transport seals remain in
place during storage.
• Do not store in direct sunlight or exposed to
excessive heat.
• A battery delivered charged (80%) must not
be stored more than 3 months up to +30°C,
or more than 6 months up to +20°C (including
transport). If a charged battery has to be
stored for more than the durations and
associated temperatures mentioned above,
discharge the cells at 0.2 C
per cell or less.
• A battery delivered discharged and filled may
be stored for many years before it is installed.
• If storage is required prior to commercial
service, clean and coat the metallic parts
with a thin layer of Rustilo DW330 or neutral
vaseline or neutral petroleum jelly grease
approved by Saft. Leave the battery in its
transport case to protect from dust, moisture
and short circuits.
3. Installation
Remove the transport seals and close the vent
plugs.
3.1. Verify that cells are correctly
interconnected and that battery connection
to the load is also correct.
3.2. Check tightness of terminal connecting
nuts.
Torque applied must be:
• 10 ± 2 N.m for cells SMRX 75 to 140
• 15 ± 2 N.m for cells SMRX 160 to 260
The connectors and terminal nuts must be
protected against corrosion by coating with a
thin layer of Rustilo DW330 or neutral vaseline
or neutral petroleum jelly anti-corrosion
greasy film.
3.3. Electrolyte
The electrolyte used is E41.
4. Commissioning
Caution: during constant charging operations,
the battery box must be open.
4.1. The cells are delivered 80% charged.
Charging and discharging should be done at
constant current.
a) For a battery stored less than 3 months at
T < +30°C, or less than 6 months at T < +20°C,
no charge/discharge operation is required
before use.
b) For a battery stored for more than 3 months
or at T > +30°C, or more than 6 months at T
> +20°C:
• Discharge the battery at 0.2 C
average 1V per cell.
Information in this document is subject to change without notice and becomes contractual only after written confirmation by Saft.
• Maintain the battery in open circuit for 8
hours or until the battery temperature is
between +10°C and +30°C.
• Charge the battery at 0.2 C
A down to 1V

4.2. The cells are delivered discharged
Caution: even if the battery is discharged,
there remains a residual charge that may
cause an electric shock.
Charging and discharging should be done at
constant current.
a) For a battery placed into service
immediately after delivery or after less than
one year of storage:
• Preferred solution: Constant current charge:
charge the battery at 0.2 C
Caution: during constant current charging the
battery box must be open.
• Other solution: Constant voltage charge:
1.55V/cell for 20 hours with the current
limited at 0.2 C5A.
b) For a battery stored more than 1 year:
• Charge the battery at 0.2 C
• Discharge the battery at 0.2 C
average 1V per cell.
• Maintain the battery in open circuit for 8
hours or until the battery temperature is
between +10°C and +30°C.
• Charge the battery at 0.2C
The battery is ready for use.
