1. Receiving the Shipment
Carefully examine the battery shipment upon arrival for any signs of transit
damage and that it agrees with the materials list or packing slip. Be very careful
not to inadvertently discard any accessories contained in the packing material.
Batteries contain sulfuric acid in glass fiber separators.
Use rubber gloves when handling broken or damaged containers in case of
acid leakage.
2. Storage
Store D ataSafe®12HX-FT batteries in a dry, clean and preferably cool location.
Since the batteries are supplied charged, storage time is limited. In order to
easily charge the batteries after prolonged storage, it is advised not to store it
more than:
 6 months at ambient temperature no warmer than 77°F (25°C)
 4 months at 86°F (30°C)
 2 months at 104°F (40°C)
Give the battery a freshening charge before the end of the recommended
storage interval.
A refreshing charge shall be performed at 2.27 volts per Cell (Vpc) at 77°F
(25°C) or 13.62 Volts per Battery (volts per block) for 96 hours or until the charge
current does not vary for a three hour period.
The necessity of a charge can also be determined by measuring the open
circuit voltage of a stored battery.
Charging is advised if the voltage drops below 2.07 Vpc. or 12.42 volts per
block
Maximum total storage prior to installation is two years from date of shipment
from the factory to the customer when stored at 77°F (25°C). Freshening
charges are required before the end of the storage time period or more
frequently, as noted above.
Failure to observe these conditions may result in greatly reduced capacity and
service life.
FAILURE TO CHARGE AS NOTED VOIDS THE BATTERY’S WARRANTY.
3. Installation
Install in clean, dry area. DataSafe 12HX-FT batteries release minimal amounts
of gas during normal operation (gas recombination efficiency ≥97%). The
batteries can be installed near the main equipment. Batteries must be
installed in accordance with federal, state and local law regulations and the
manufacturer’s instructions.
 Temperature
Avoid placing batteries in areas of high temperature or in direct sunlight. The
batteries will give their optimum service life when operating at a temperature
between 68°F (20°C) and 77°F (25°C), however they are capable of operating
in a temperature range of -22°F (-30°C) to 122°F (50°C). Please reference the
charging float voltage section for more information regarding float voltage
adjustments for temperature variations. Reasonable precautions should be
taken to prevent continuous operation below -22°F (-30°C) or above 122°F
(50°C).
 Ventilation
Under normal conditions gas release is very low and natural ventilation is
sufficient for cooling purposes and inadvertent overcharge, enabling DataSafe
12HX-FT 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.
 Stowing
For proper installation, EnerSys®battery racks and cabinets are recommended.
Attention: Unless otherwise noted, battery racks and cabinets should not be
transported with rigid intercell connectors in place.
Intercell connector covers should be installed after completing the intercell
connections.

 Torque
Tighten the M8 connector bolts to 160 in-lbs (18.1Nm). A loose connector can
cause problems in charger adjustment, erratic battery performance, possible
damage to the battery and/or personal injury. A loose connector or a connector
not sitting flush on the battery terminal can cause problems.
Batteries come standard with a stainless steel hardware package. The
hardware package includes (2) M8-1.25, flat washers and lock washers.
Additional accessories are available for purchase.
4. Cells in Parallel Strings
When utilizing a constant voltage charger, ensure that the connections from
the charger at the end of each string have the same electrical resistance.
To reduce the risk of current imbalance, the number of parallel strings in any
system should be limited to six.
5. Charging
 Commissioning Charge
Upon installation, perform a Commissioning Charge on the battery with a
constant voltage charger by either:
- Charging at 2.40 Vpc at 77°F (25°C) for 24 hours or
- Charging at 2.35 Vpc at 77°F (25°C) for 72 hours.
Follow the Maximum Charging Current values shown in Table 1. After
completion of the Commissioning Charge at either level, reduce the charger to
the appropriate Float Charge level for the battery temperature shown in the Float
Charge Section. A discharge test can be given after float charging for 24 hours.
 Float Voltage
The float/charge voltage is 2.27 Vpc at 77°F (25°C).
When the average ambient temperature deviates ± 9°F (5°C) or more from the
reference, it is necessary to adjust the float voltage as follows:
2.33 to 2.36 Vpc at 32°F (0°C)
2.30 to 2.33 Vpc at 50°F (10°C)
2.27 to 2.30 Vpc at 68°F (20°C)
2.25 to 2.28 Vpc at 77°F (25°C) (reference)
2.23 to 2.26 Vpc at 86°F (30°C)
2.22 to 2.25 Vpc at 95°F (35°C)
 Equalize Charge
The battery can be charged at an elevated voltage of 2.40 Vpc (14.4 Volts
for the battery) for the purpose of an equalize charge or as part of a 2-step
recharge profile to reduce charge time. Charge time at 2.40Vpc should not
exceed 16 hours and the current limits in Table 1 must be followed.
 Ripple Current
Unacceptable 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 the values of the Table 1 (in amperes).
Table 1
 Charging Current
The recommended charging method for DataSafe 12HX-FT batteries is current
limited, constant voltage charging. Refer to Table 1 for the current limits for
each battery model.
 State of Charge
The battery state of charge can be determined approximately by measuring
the open circuit voltage after the battery has been at rest for a minimum of 24
hours at 77°F (25°C). See Table 2.
Table 2
State of Charge Voltage per Cell Voltage per Battery
100% 2.12 to 2.14 12.72 to 12.84
80% 2.09 to 2.11 12.54 to 12.66
60% 2.05 to 2.08 12.30 to 12.48
40% 2.01 to 2.04 12.06 to 12.24
20% 1.97 to 2.00 11.82 to 12.00
6. Discharging
 End of Discharge Voltage
The end of discharge voltage must be limited to a minimum value of 1.60 Vpc.
or 9.60 VPB
A protecting system must be installed to prevent deep discharge.
 Discharged Cells
DataSafe 12HX-FT 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 sulfuric acid is completely
absorbed and the remaining electrolyte consists only of water.
At this point, the sulfation 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.
For temperature correction factors for use when load testing a battery,
please refer to the Temperature Correction factor tables published in
IEEE Standard 1188, latest version.
7. Maintenance and Records
DataSafe 12HX-FT batteries are virtually maintenance-free, sealed, lead acid
batteries and need no water addition. These batteries are equipped with self-
resealing, flame-arresting safety vents.
The containers and lids shall be kept dry and free from dust. Cleaning must
be done with a cotton cloth dampened with water only. Check monthly that
total voltage at battery terminals, while on float, is (N x 2.25 to 2.28 Vpc) for a
temperature of 77°F (25°C), (where N is the number of cells in the battery).
Every 12 months, read and record the following:
 Individual battery voltages (in volts)
 Cell-to-cell connection resistance (in ohms)
 Terminal connection resistance (in ohms)
 Ambient temperature in the immediate battery environment
Keep a logbook to record values, power outages, discharge tests, 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.
