EnerSys PowerSafe SBS Series User manual

PowerSafe®SBS 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
1.1 In-Transit Damage or Short Shipments
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.
1.2 Shipment Damage or Shortages
Open the shipping containers and check the contents for
damage and against the packing slip. Immediately inform
EnerSys of any damaged or missing items.
EnerSys is not responsible for damaged or missing items
after a shipment has been in storage.
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 batteries 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.
The maximum storage times before a freshening charge is
required and recommended open circuit voltage audit
intervals are:
Monoblocs must be given a freshening charge when bloc
voltages approach the equivalent of 2.10 Volts per cell or
when the maximum storage time is reached, whichever
occurs first.
2.2 Commissioning Charge
Before conducting a capacity discharge or fully loaded duty
cycle test, the battery must be given a commissioning
charge. The commissioning charge shall consist of 7
continuous days of float charge at the recommended float
voltage (2.29Vpc at 20°C) with no load connected to the
battery.
2.3 Freshening Charge
Charge the monoblocs, or strings at a constant voltage
equivalent to 2.29 - 2.4Vpc with 10% of the C10 current
available for a period of 24 hours.
3. Battery Location
The battery compartment/room must have adequate
ventilation to limit hydrogen accumulation to a maximum of
1% by volume of free air.
4. Installation
Each monobloc is supplied with the terminal/connector
fasteners.
On each monobloc the positive terminal is identified 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 with the connectors and fasteners
provided. The fastener torque value is:

batteries.
Contains lead
California Proposition 65 Warning – Battery posts,
terminals and related accessories contain lead and lead
compounds, chemicals known to the State of California
to cause cancer and reproductive harm. Wash hands
after handling.
Warning: Risk of fire,
explosion, or burns.
Do not disassemble, heat
above 60ºC, or incinerate.
Avoid any short circuit.
Metallic parts under voltage on the
battery, do not place tools or items on
top of the battery

Publication No. EN-SBS-IS-008 - February 2012 - Subject to revisions without prior notice. E.&O.E.
Place the insulating covers in position immediately after
tightening the fasteners.
5. 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. The minimum charging
voltage, at any temperature, is 2.21Vpc. The recommended
float voltage temperature compensation is:
Disconnecting the battery from the load when the
recommended end voltage is reached will eliminate the risk
of over-discharge. We recommend that the charge voltage is
reapplied within 24 hours, up to a maximum of 7 days, of
any discharge.
6. Maintenance
In practice, the user usually specifies the maintenance
schedule based on site criticality, location and manpower.
The following is a suggested maintenance schedule.
• Monthly (record all readings)
Measure the battery string voltage. If necessary, adjust the
float voltage to the correct value.
• Every six months (record all readings)
Measure the battery string voltage. If necessary, adjust the
float voltage to the correct value.
Measure individual bloc voltages. The blocs should be within
5% of the average.
Inspect for contamination by dust, loose or corroded
connections. If necessary isolate the string/bloc 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.
7. Disposal
PowerSafe®SBS 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 certified lead acid battery
recycler.
