Danger
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.
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.

Instruction Sheet
The maximum storage times before a freshening charge is
required and recommended open circuit voltage audit
intervals are:
Temperature
(°C / °F)
+10 / +50
+15 / +59
+20 / +68
+25 / +77
+30 / +86
+35 / +95
+40 / +104
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 C
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:
