1. Receiving
Upon the receipt of the shipment, check the contents against the packing slip and for
damage. Immediately inform EnerSys®of any missing or damaged 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 installed immediately it should be stored in a clean, cool and
dry area. During storage monoblocs / cells lose capacity through self-discharge. High
temperatures increase the rate of self-discharge and reduce the storage life.
2.1.1. The graph below shows the relationship between open-circuit voltage (OCV) and
storage time at various temperatures.
2.1.2. The maximum storage time before a refresh charge is required and the
recommended OCV audit intervals are:
Temperature
(°C / °F)
Storage Time
(Months)
OCV Audit Interval
(Months)
+10 / +50 48 12
+15 / +59 34 12
+20 / +68 24 12
+25 / +77 17 6
+30 / +96 12 6
+35 / +95 8.5 3
+40 / +104 6 3
2.1.3. Monoblocs and 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 rst.
2.2. Refresh Charge
Charge the monoblocs / cells or strings at a constant voltage equivalent to 2.29 -
2.40Vpc with a minimum 0.1C10 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
0.1C10 Amps with no load connected to the battery. Either of the following methods can
be used:
• Charge for 7 days at the recommended oat voltage of 2.29Vpc at 20°C, or
• Charge for 24 hours at the recommended boost charge voltage of 2.40Vpc at 20°C.
The battery will then be switched over to oat charging, maintaining the battery at
oating 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 EN 50272-2 standard
and any other local/national laws and regulations.
4. Installation
Whatever your application, SuperSafe SBS XC batteries can be mounted in any
orientation except inverted.
However, in cyclic applications, EnerSys recommend to install 2 Volt DIN-size cells in
horizontal orientation. In such con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 seal is resting on a runner.
• Always ensure that the arrow on the lid of each unit is pointing in vertical
orientation.
Each monobloc / cell is supplied with terminal/connector fasteners.
The positive terminal is identied by a“+” symbol on each monobloc / 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.
Handling
SuperSafe SBS XC 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.
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
Keep ames away
In case of accidental overcharge a ammable gas
can leak o 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.

Warning: Risk of re, 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.
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.

5. Operation
SuperSafe SBS XC monoblocs and cells are specically designed for cyclic unreliable
grid applications where, due to the demands on the battery, there is a high risk of
uncontrolled partial state of charge operation.
The battery will give the best performance and service life when working at a
temperature of 20°C. The maximum operating temperature range is -40°C to +50°C.
5.1. Float Voltage Operation
Constant voltage chargers are recommended. The charging voltage should be set at the
equivalent of 2.29Vpc at 20°C / 68°F.
The recommended oat voltage temperature compensation is:
• 2.29Vpc +3mV per cell per °C below 20°C
• 2.29Vpc -3mV per cell per °C above 20°C
5.2. Fast Charge Operations
The inherently high charge acceptance of TPPL Technology used in the SuperSafe
SBS XC is suited for applications which require a fast time to repeat duty, in such
applications the rectier voltage should be set at 2.35Vpc to 2.40Vpc at 20°C.
Once fully charged the voltage can be changed to oat voltage with temperature
compensation as required.
Further details can be found in our SuperSafe SBS XC Operating Guide for Unreliable
Grid Applications.
5.3. Charging Current
Due to their very low internal resistance SuperSafe SBS XC batteries will accept
unlimited current during recharge. However, for cost and practicality purposes in oat
applications where minimizing recharge time to support repeat duty is not critical, the
rectier current can be limited to the load plus 0.1C10 Amps (minimum).
5.4. Discharging
Batteries must not be left in a discharged condition after supplying the load but must
immediately return to recharge mode.
Failure to observe these conditions may result in greatly reduced service life.
5.5. Accidental deep discharging
In order to protect the battery it is advisable to have system monitoring and low voltage
cut-out. A low voltage disconnect of 1.93 Vpc (80% DoD) should be applied to protect
the battery from abusive over discharge.
Abusive deep discharge can result in premature deteriation of the battery and a
noticeable reduction in the life expectancy.
5.6. Eect of temperature
Operation of valve regulated batteries at temperatures higher than 20°C will reduce life
expectancy. Life is reduced by 50% for every 10°C rise in temperature.
5.7. Unreliable Grid Operation with high risk of Uncontrolled Partial State of
Charge
The high charge acceptance capability of SuperSafe SBS XC monoblocs and cells allows
the use of fast charge techniques. This enables the battery to be brought towards full
state of charge quicker and having greater battery capacity available in the event of
further power outages. Where power outages are frequent SuperSafe SBS XC can be
operated in partial state of charge conditions. It is very important to return the battery
to full state charge to ensure it does not suer from reduced performance due to the
build-up of irreversible sulphation.
Once the battery is brought to full state of charge the voltage setting should revert to
oat voltage, with temperature compensation applied, in order to prevent prolonged
periods of overcharge.
Further details can be found in our SuperSafe SBS XC Operating Guide for Unreliable
Grid Applications.
6. Data Recording
It is recommended that as a minimum, the following information be recorded by means
of regular data logging – which the user must make available to EnerSys® to validate
any warranty claim,
1) Records of the commission charge.
2) The number of cycles performed and the depth of discharge (“DoD”) of each cycle.
3) The duration of each discharge and charge cycle, and the Ah in and out (Wh in and
out).
4) Full details of the recharge voltage/current prole for the last 50 cycles.
5) A full history of the ambient and battery surface temperatures, recorded at regular
intervals throughout battery operation and life.
6) The time and date of each“event” (an “event” is dened as the start/stop of the
battery discharge, the start/stop of the battery recharge, the start stop of any
generator input power or other input power source, etc).
Contact EnerSys if you have any questions regarding maintenance.
7. Disposal
SuperSafe SBS XC 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 certied lead acid battery recycler.
