Handling
PowerSafe
®
SBS XL blocs and cells 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.
Important
Please read this manual immediately on receipt of the battery before unpacking and installing. Failure to comply with these instructions will render any
warranties null and void.
Care for your safety
2
Keep flames away
In case of accidental overcharge a flammable gas
can leak off the safety vent.
Discharge any possible static electricity from
clothes by touching an earth connected part.
Tools
Use tools with insulated handles.
Do not place or drop metal objects on the battery.
Remove rings, wristwatch and articles of clothing with
metal parts that may come into contact with the battery
terminals.
No smoking,
no naked flames,
no sparks

Clean all acid splash in eyes or on
skin with plenty of clean water.
Then seek medical help. Acid on
clothing is to be washed with water.
Warning: Risk of fire, explosion, or burns. Do not
disassemble, heat above 60°C (140°F), or incinerate.
Metallic parts under voltage are present on the
battery, avoid short circuit. Do not place tools or
items on top of the battery.

1. Receiving
Upon the receipt of the shipment, check the contents for damage and
against the packing slip. Immediately inform EnerSys of any damaged
or missing items. 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 and dry area. During storage blocs and cells lose capacity through
self-discharge. High temperatures increase the rate of self-discharge and
reduce the storage life.
The chart below shows the relationship between open-circuit voltage (OCV)
and storage time at various temperatures.
Blocs/cells must be given a refresh charge when the OCV approaches
the equivalent of 2.10 Volts per cell or when the maximum storage time
is reached, whichever occurs first.
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.
2.2. Refresh Charge
Charge at a constant voltage equivalent to 2.29 – 2.40Vpc with a minimum
0.1C
10
Amps available for a period of 24 hours.
2.3. Commissioning Charge
Before commencing operation, the battery must be given a commissioning
charge. The batteries should be charged using constant voltage with
a minimum charge current of 0.1C
10
Amps with no load connected to
the battery. Either of the following methods can be used:
• Charge for 96 hours at the recommended float voltage of 2.29Vpc
at 20°C / 68°F or
• Charge for 24 hours at the recommended boost charge voltage of
2.40Vpc at 20°C / 68°F. The battery will then be switched over to float
charging, maintaining the battery under floating voltage for 24 hours
before any discharge test.
3. Battery Location
The battery compartment/room must have adequate ventilation to limit
hydrogen accumulation. Batteries must be installed in accordance with
the IEC 62485-2 standard and any other local/national laws and regulations.
4. Installation
PowerSafe SBS XL batteries are designed for stable grid float applications
(non-cyclic applications). 12V blocs can be installed on their base
or horizontally on their longest side whilst 2V cells can be mounted
in any orientation except inverted.
With regards to the installation of 2V cells in horizontal orientation
specifically, 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 seal is resting
on a runner.
• Always ensure that the arrow on the lid of each unit is pointing
in vertical orientation.
Each bloc / cell is supplied with terminal/connector fasteners.
The positive terminal is identified by a “+” symbol on each bloc / cell.
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.
The fastener torque value is indicated on the product label.
Place the insulating covers in position immediately after tightening
the fasteners.
