EnerSys SuperSafe SBS EON Series User manual

SuperSafe® SBS® EON Technology® batteries are supplied in a
charged condition, and are capable of extremely high short circuit
currents. Take care to avoid short-circuiting terminals of opposite
polarity.
1. Receiving
Upon receipt of a shipment, check that the items delivered
are undamaged and match the carrier’s Bill of Lading.
Report any damage or shortages to the carrier. EnerSys®
is not responsible for shipment damage or shortages
that the receiver does not report to the carrier.
2. Storage
2.1 Storage Conditions and Time
If a battery cannot be immediately installed it should be
stored in a clean, cool, dry area.
During storage monoblocs and cells lose capacity through
self-discharge.
High temperature increases the rate of self-discharge and
reduces the storage life.
The chart below shows the relationship between open-circuit
voltage (OCV) and storage time at various temperatures.
2.2 Refresh Charge
Monoblocs and cells must be given a freshening charge
when the OCV approaches the equivalent of 2.10 Volts per
cell or when the maximum storage time has been reached.
Freshening charge should be by means of constant voltage
charge set between 2.29 and 2.40Vpc with current limit
0.1C10 A for 24 hours. Recommended OCV audit intervals are
given in the table below.
2.3 Commissioning Charge
Before conducting a capacity discharge or commencing
cycling, the battery must be given a commissioning charge.
In f oat applications the commissioning charge shall consist
of 7 continuous days of f oat charge at the recommended
f oat voltage (2.29Vpc at 20°C) with no load connected to the
battery. In hybrid applications the commissioning charge
shall consist of 24 hours charge at a voltage equivalent to
2.40 Volts/cell with no load connected.
3. Installation
Whatever your application, SuperSafe SBS EON Technology
blocs and cells can be mounted in any orientation except
inverted. However, in cyclic/hybrid applications, EnerSys
recommend to install DIN-sized SBS EON Technology 2V
cells in horizontal orientation. In such conf guration the
instructions below must be complied with.
•Do not use terminal posts to lift or handle cells.
•Do not install the cells in such a way that the box-lid bond
is resting on a runner.
•Always ensure that the arrow on the lid of each unit is
pointing in vertical orientation.
The battery compartment/room must have adequate
ventilation to limit hydrogen accumulation to a maximum of
1% by volume of free air.
Each monobloc/cell is supplied with the terminal/connector
fasteners.

On each monobloc/cell the positive terminal is identif ed by a
“+” symbol. Install the batteries in accordance with the
instructions and/or layout drawing, taking care to ensure
correct terminal location and polarity.
Connect the blocs/cells with the connectors and fasteners
provided. Tighten the fastener set bolt(s) / nut(s) to the
fastening torque level indicated on the product label.
Place the insulating covers in position immediately after
tightening the fasteners.
4. Operation
SuperSafe® SBS® EON Technology® monoblocs and cells
retain the long f oat life and storage characteristics of
traditional SuperSafe SBS monoblocs and cells with the
added benef t of improved cyclic ability in both f oat
voltage and fast charge modes.
4.1 Stand by / Float Operation
Constant voltage chargers are recommended. The charging
voltage should be set at the equivalent of 2.29Vpc at 20°C/68°F
or 2.27Vpc at 25°C/77°F.
Operation at temperatures higher than 20°C will reduce life
expectancy. Life is reduced by typically 50% for every 10°C rise
in temperature. To offset the impact of higher temperatures
compensation to the f oat voltage should be applied.
The recommended f oat voltage temperature compensation is:
Due to the very low internal resistance, SuperSafe SBS EON
monoblocs and cells will accept unlimited current during
recharge but for cost and practical purposes in f oat
applications where recharge time to repeat duty is not critical,
the rectif er current can be limited to the load plus 0.1C10
Amps.
4.2 Cyclic Operation
In addition to the long life characteristics inherent in
traditional SuperSafe SBS TPPL designs, EON Technology has
been developed to provide high performance in applications
where the battery is subjected to repeated cyclic duty or
where power reliability is tested by high temperatures and
harsh conditions combined with remote locations.
In cyclic applications the charging voltage should be set at the
equivalent of 2.40Vpc cell at 20°C/68°F, with the rectif er
current limit set to a minimum of 0.1C10 A (EON Technology is
designed to accept unlimited in rush currents without causing
damage to the internal electro chemistry).
The optimal cyclic performance is achieved by returning the
battery to full state of charge between discharge cycles. It is
possible to operate SBS EON Technology monoblocs and cells
in partial state of charge condition, however, in such situations
it is very important to ensure that the battery is periodically
returned to full state charge to maintain battery state of health.
It is recommended to contact your EnerSys®representative to
obtain additional information and guidance for such psoc
applications.
In systems where control of charge factor is not possible, it
may be possible to estimate time to full state of charge by
using the calculation:
Recharge time (hrs) = 2* ((0.8 x discharged Ah) / current limit) +1
The recommended compensation for charge voltage in cyclic
applications is:
5. Maintenance
In practice, the user usually specif es the maintenance
schedule based on site criticality, location and manpower.
However, the following may be used as a suggested
maintenance schedule.
• Monthly (record all readings)
Measure the battery string voltage. If necessary, adjust the
f oat voltage to the correct value.
• Every six months (record all readings)
Measure the battery string voltage. If necessary, adjust the
f oat voltage to the correct value.
Measure individual bloc/cell voltages. The blocs/cells
should be within 5% of the average.
Inspect for contamination by dust, loose or corroded
connections. If necessary isolate the string/bloc/cell and
clean with a damp soft cloth. Warning - Do NOT use any
type of oil, solvent, detergent, petroleum-based solvent or
ammonia solution to clean the battery containers or lids.
These materials will cause permanent damage to the
battery container and lid and will invalidate the warranty.
Contact EnerSys®if you have any questions regarding
maintenance.
6. Disposal
SuperSafe SBS EON Technology batteries are recyclable.
Scrap batteries must be packaged and transported in
accordance with prevailing transportation rules and
regulations.
Scrap batteries must be disposed of in compliance with
local and national laws by a licensed or certif ed lead acid
battery recycler.
