Upon receipt of the shipment, check the contents for damage and
completeness 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.
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 installed immediately, it should be stored in a
clean, cool and dry area. During storage monoblocs 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.

3. Battery Location
The battery compartment/room must have adequate ventilation
to limit hydrogen accumulation. Batteries must be installed in
accordance with prevailing standards and any other local/national
laws and regulations.
4. Installation
Install in a clean and dry area. DataSafe®HX+batteries
release minimal amounts of gas during normal operation (gas
recombination efficiency ≥95%). They can be installed near the
main equipment. Batteries must be installed in accordance with
local, national and international regulations and manufacturer’s
instructions.
Temperature
Avoid placing the battery in areas of high temperature or in direct
sunlight. The battery will give the best performance and service
life when working at a temperature between 20°C and 25°C. The
maximum operating temperature range is -30°C to +45°C.
Ventilation
Under normal conditions gas release is very low and natural
ventilation is sufficient for cooling purposes and inadvertent
overcharge, enabling DataSafe HX+batteries to be used safely in
offices and with main equipment.
However care must be taken to ensure adequate ventilation when
placed in cabinets. Batteries must not be placed in sealed cabinets.
Security
All installation and ventilation must comply with the current local,
national and international regulations.
Mounting
Batteryracksorcabinets,suppliedbyEnerSys,are recommended
for proper installation. Assemble the rack according to
instructions. Place the monoblocs or cells on the rack and arrange
the positive and the negative terminals for connection according
to the wiring diagram. Check that all contact surfaces are clean
and apply the bloc or cell connectors and the terminal screws.
Tighten the screws securely. Follow the polarity to avoid short
circuiting of cell groups. Finally connect the battery terminals. It is
important that the battery is mounted firmly.
Installation of High Voltage Batteries
A battery consisting of 10 or more blocs connected in series
presents additional hazards and the following notes on installation
should be employed.
• During installation process, limit the battery voltage by omitting
inter-cell connectors to give a maximum section voltage of 120V
or 10 blocs.
• The omitted inter-cell connectors should be chosen such that
they are in an easily accessible position. These connectors
should only be fitted with the load and charger isolated and
when the rest of the installation is complete.
•Never work alone on high voltage batteries.
• Always use insulated tools and wear approved high voltage
insulating gloves.
• When supplied, fit the “high voltage battery” warning labels in a
prominent position.
Torque
Tighten the nuts or bolts to the recommended levels of fastening
torque indicated on the product label (if applicable). A loose
connector can cause problems in charger adjustment, erratic
battery performance, possible damage to the battery, and/or
personal injury.
Blocs in Parallel Strings
When using constant voltage chargers, ensure that the connections
between the charger and the end of each string within the battery
have the same electrical resistance. Parallel strings should be
limited to five strings except with an expressed written consent
from EnerSys. Parallel strings of five or more require a battery
monitoring system that records both voltage and current by string.
5. Operation
5.1. Float Voltage
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 as follows:
Temperature (°C/°F)
Due to the phenomena of gas recombination, it is not uncommon
to note a variation in individual block float voltages of 2% (or up to
5% for relatively new batteries). However the total voltage of the
battery shall be within the limits stated above.
5.2. Charging Current
Utilising a constant voltage charger results in a charging current
that is self limiting. The minimum rectifier current available should
be the load plus 0.1C10 Amps.
5.3. Fast Recharge
Occasionally (4 to 5 times per year) the battery may be recharged
at 2.40Vpc at 20°C, with the rectifier current limit set to a minimum
of 0.1C10 A. Fast charge should be stopped and reverted to float
voltage after approximatly 10 to 15 hours.
5.4. Periodic Boost Charge
In normal operation a periodic boost charge is not required.
However, in some cases such as when extended or repeated line
power outages result in the battery exeriencing extended periods of
undercharging, a boost charge equivalent to 2.40Vpc at 20°C for a
maximum of 15 hours can be applied.
5.5 Ripple Current
Unaccepatble levels of ripple current from the charger or the load
can cause permanent damage and a reduction in service life. It is
recommended to limit the continuous ripple current to 0.05C10A.
5.6 Discharging
For maximum battery life, the end of discharge voltage should
be limited to 1.60Vpc. Failure to protect batteries from discharges
exceeding this level may impact the warranty.
In order to protect the battery it is advisable to have system
monitoring and low voltage cut-out. Deep discharge will produce a
premature deterioration of the battery and a noticeable reduction in
the life expectancy of the battery.
Discharged Monoblocs
DataSafe HX+batteries must not be left in a discharged condition
after supplying the load, but must be immediately returned to float
recharge mode. Failure to observe these conditions may result in
greatly reduced service life and unreliability.
Accidental Deep Discharge
When the battery is completely discharged, the sulphuric acid is
completely absorbed and the remaining electrolyte consists only of
water. At this point, the sulphation of the plates is at its maximum,
considerably increasing the cell’s internal resistance.
Important notice: this type of deep discharge will provoke a
premature deterioration of the battery and a noticeable effect on
life expectancy.
6. Maintenance and Records
In practice, the user usually specifies 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 float
voltage to the correct value.
10/50 15/59 20/68 25/77 30/86 35/95 40/104

etc.
An autonomy check can be carried out once or twice a year.
The above record taking is the absolute minimum to protect the
warranty.
This data will be required for any warranty claim made on the
battery.
Contact EnerSys®if you have any questions regarding
maintenance.
7. Disposal
DataSafe®HX+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.
