SPL+ Ni-Cd batteries
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 earthconnected part "ground" before
working on the battery.
2.3. Ventilation
During the last part of charging, the
battery emits gases (oxygen and
hydrogen). At normal float charge the
gas evolution is very small but some
ventilation is necessary.
Note that depending on the application
and local regulations, specific ventilation
practices may be necessary.
2.4. Electrolyte
When checking the electrolyte of new
cells, a variation in electrolyte levels
between cells is normal. This is due to
the varying amounts of gas held in the
separators of each cell. With this
variation, the minimum level observed
should be at least 15 mm (5/8")
above the minimum level mark (lower).
Do not top up with deionized or
distilled water prior to initial charge to
avoid over-filling a cell.
If electrolyte is ever spilled from a cell
and the level is 30 mm below the
minimum mark (lower), then refilling
with E23 electrolyte is required.
Contact your local Saft representative
for more details.
3. Commissioning
1. Receiving the shipment
Do not overturn the package.
The SPL+ cells are shipped filled and
charged, and ready for immediate use.
2. Installation
2.1. Location
Install the battery in a dry and clean
room. Avoid direct sunlight and heat.
The battery gives the best
performance and maximum service
life when the ambient operating
temperature is between +10°C
to +30°C (+50°F to +86°F).
2.2. Assembly
For cells with handles, both must
be used when lifting and moving.
To prevent electrolyte spillage, do not
tip cells.Verify that cells are correctly
interconnected with the appropriate
polarity. The battery connection to load
should be with nickel plated cable lugs.
Before torqueing connections, apply a
thin coating of anti-corrosion grease
(NO-OX) or anti-corrosion oil to all the
terminals and connectors.
Torque the terminal bolts to 30 ± 3 N.m
(22 +/- 2 ft/lbs). If the transport
seals are present, remove them from
underneath the vent caps and re-close.
IMPORTANT: During commissioning
charge hydrogen and oxygen gas is
vented from the cells.
Verify that the ventilation is adequate
during this operation.
Cells stored up to 6 months:
A commissioning charge is optional
and the cells are ready for immediate
use. If full performance is required
immediately after installation, conduct
a commissioning charge.
Cells stored more than 6 months
and up to 2 years:
Always conduct a commissioning
charge before use.
Commissioning charge procedure
There is 3 recommended methods,
depending on equipment voltage limits.
• Commissioning at ambient
temperature between + 10°C to
+ 30°C (+ 50°F to + 86°F)
- Constant current charge:
Charge for 20 h at 0.1 C5 A
maximum (see Table A) with at least
1.80V/cell at the end of charge.
- Constant voltage charge:
Charge at 1.55 V/cell for a minimum
of 24 h with current limited to
0.1 C5 A (see the current in Table A).
Or charge at 1.50 V/cell for a minimum of 36 h with current limited to
0.1 C5 A (see the current in Table A).
• Commissioning at ambient
temperature above + 30°C (+ 50°F)
- Only constant current charge:
Charge for 20 h at 0.1 C5 A
maximum (see Table A).
The electrolyte temperature should
be monitored. If the electrolyte
temperature ever exceeds + 45°C
(+ 113°F) during commissioning
charge, stop the charge and rest the
cells until the electrolyte temperature
drops below +40°C (+104°F) before
continuing the commissioning charge.
Following the commissioning charge
and after placing the battery in
service, check the electrolyte levels
as topping-up may be necessary.
Note: To evaluate the full battery
performance, it is required to
charge and discharge the SPL+ in
accordance with IEC62259 section
7 (7.1 & 7.2).
4. Charging in service
It is recommended to charge the SPL+
using a Single level voltage or a Dual
level voltage method.
Single level voltage:
• 1.42 ± 0.01 V/cell
Dual level voltage:
• float level:
1.42 ± 0.01 V/cell
• high rate (boost) level:
1.45 ± 0.01 V/cell
For use at temperatures outside
the range of +15°C to +25°C (+59°F
to +77°F), Temperature Compensated
Voltage (TCV) is recommended.
This minimizes the need for topping-up
maintenance at high temperatures
and increases the charge acceptance
at low temperatures.
The recommended TCV control value is
–3 mV/°C/cell (–1.7 mV/°F/cell).

5. Preventive maintenance
SPL+ is an ultra-low maintenance
battery which requires little to no
maintenance. For preventative
maintenance, the following is
recommended. All recommendations
mentioned are in accordance with
IEEE 1106 “Recommended Practice
for Installation, Maintenance, Testing
and Replacement of Vented NickelCadmium Batteries for Stationary
Applications”. Additionally, follow
your standard preventative
maintenance procedures.
eep the battery clean.
The battery can be wiped using only
water. Do not use solvents of any
kind. Soft non-metallic brushes and
cloths can be used. Vent plugs can
be soaked and rinsed in clean water
if necessary.
heck the charging voltage.
This should be checked and recorded
at least once yearly.
High water consumption is usually
caused by an improper voltage
setting or voltage drift that is above
the recommended in service
charging voltages.
isually check the electrolyte levels.
If the levels are at or below the
minimum level mark (lower), toppingup is required using only deionized or
distilled water. Experience will tell the
time interval between topping-up.
Note: There is no need to check
the electrolyte density Electrolyte
density measurements do not
indicate state of charge or state
of health.
CAUTION: Topping-up should be
done only when the SPL+ is in
float charge operation mode.
heck the terminal bolt torque every
two years.
Ensure all terminals and connectors
are coated with a thin layer of anticorrosion grease (NO-OX) or anticorrosion oil.

Note that all these maintenance
recommendations followed the IEEE
1106 standard “Recommended
Practice for Installation, Maintenance,
Testing and Replacement of Vented
Nickel-Cadmium Batteries for
Stationary Applications”.
6. Storage
Store the battery indoors in a dry,
clean, cool location 0°C to +30°C°
(+32°F to +86°F) and well ventilated
space on open shelves.
Storage of a filled battery at
temperatures above +30°C (+86°F)
can result in loss of capacity.
The capacity loss can be as much as
5% per 10°C (18°F) above +30°C
(+86°F) per year.
Do not store in direct sunlight or
expose to excessive heat.
SPL+ cells are supplied filled with
electrolyte and charged and in that
state, they can be stored for
maximum 24 months.
Never drain the electrolyte from
the cells.
