BCI Warning
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 ber separators.
Use rubber gloves when handling broken or damaged containers in case of
acid leakage.
2. Storage
Store DataSafe 16HX-FT batteries in a dry, clean and preferably cool location.
Although batteries are supplied charged, their storage time is limited. The
maximum storage intervals prior to a required refreshening charge, based on
the battery’s date code label, are as follows:
■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)
A refreshening charge shall be performed at 2.27 Volts Per Cell (Vpc) or 18.08
Volts Per Battery (Vpb) at 77ºF (25°C) 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 (16.56 Vpb).
Maximum total storage prior to installation is two years from date of shipment
from the factory to the customer. 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 16HX-FT batteries release minimal
amounts of gas during normal operation (gas recombination efciency ≥
97%). The batteries can be installed near the main equipment. Batteries must
be installed in accordance with local, state and federal regulations and the
manufacturer’s instructions.
■
Temperature
Avoid placing batteries in areas of high temperature or in direct sunlight. The
batteries will give their best performance and 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 16HX-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.
For rack installations, reference Assembly Instructions for DataSafe HX and
HX Front Terminal UBC Battery Racks (US-HXRACK-IM).
For cabinet installations, reference Installation, Operation and Maintenance
Manual for DataSafe Front Terminal Battery Cabinets (US-HXFT-CAB).
Intercell connector covers (provided) should be installed after completing the
intercell connections.
Attention: Unless otherwise noted, battery racks and cabinets should not be
transported with intercell connectors installed.

■ Torque
Tighten the M8 connector bolts between 100 and 110 in-lbs (11.3 to 12.5
N•m). A loose connector can cause problems in charger adjustment,
erratic battery performance, possible damage to the battery and/or
personal injury.
NOTE: Top terminal connections are secured with Nord-Lock®washers.
These washers provide an effective terminal connection over the
life of the battery. If loosened, this connection should be tightened
between of 80 and 90 in-lbs (9 to 10 N•m).
4. Cells in Parallel Strings
When utilizing a constant voltage charger, ensure that the connections from the
charger and 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 inTable 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 oat charging for 24 hours.
■
Float Voltage
The float/charge voltage is 2.27 Vpc (18.08 Vpb) at 77°F (25°C). When the
average ambient temperature deviates more than ± 9°F (5°C) from the
reference, it is necessary to adjust the float voltage as follows:
2.33 to 2.36 Vpc (18.64 to 18.88 Vpb) at 32°F (0°C)
2.30 to 2.33 Vpc (18.40 to 18.64 Vpb) at 50°F (10°C)
2.27 to 2.30 Vpc (18.16 to 18.40 Vpb) at 68°F (20°C)
2.25 to 2.28 Vpc (18.00 to 18.24 Vpb) at 77°F (25°C) (reference)
2.23 to 2.26 Vpc (17.84 to 18.08 Vpb) at 86°F (30°C)
2.22 to 2.25 Vpc (17.76 to 18.00 Vpb) at 95°F (35°C)
■ Equalize Charge
The battery can be charged at an elevated voltage of 2.40 Vpc (19.2 Volts for the
battery) for the purpose of an eqauilize charge or as part of a 2-step recharge prole
to reduce charge time. Charge time at 2.40V should not exceed 16 hours and the
current limits inTable 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).
■
Charging Current
The recommended charging method for DataSafe®16HX-FT batteries is
constant voltage charging. Follow the maximum charge current values in
Table 1.
■
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). Refer to Table 2 for these approximations.

6. Discharging
■
End of Discharge Voltage
The end of discharge voltage must be limited to a minimum value of 1.60 Vpc
(12.8 Vpb). A protecting system must be installed to prevent deep discharges.
■
Discharged Cells
DataSafe 16HX-FT batteries must not be left in a discharged condition after
supplying the load, and 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.
■
The Effect of Temperature on Capacity
The optimum operating temperature for DataSafe 16HX-FT batteries is 77°F
(25°C). The capacity of a battery operated above this optimal temperature
generally increases at the expense of battery life while operating below this
optimal temperature extends life but at the expense of capacity. Please refer
to the recommended practices outlined in IEEE 1188 when determining the
effect of temperature on battery capacity.
7. Maintenance and Records
DataSafe 16HX-FT batteries are virtually maintenance free, sealed, lead acid
batteries and need no water addition. These batteries are equipped with self-re-
sealing, ame-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 oat, is (N x 2.25 to 2.28 V) 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.
