Freshening
Charge
Battery
Connection
to the Load I Charger
Select the proper size and type of cable per the NEC
or other applicable code which can handle the charge
and discharge current related to the battery. The cable
size selected should also consider the cable
resistance per foot and the voltage drop allowed
between the battery output terminals and the load.
The output circuit of the battery should contain a DC
rated fuse or circuit breaker to protect the wiring and
where appropriate a disconnect
to facilitate service to
the battery in an open circuit condition.
When the batteries have been in storage or transit for
an extended period or the battery system is intended
for use at the minimum float charging voltage or when
the number of cells in series is greater than 24, it is
recommended
the battery system be given a
freshening charge at 2.4 volts average per cell for 24
hours. This will assure higher initial performance
and
will reduce the time period required for the cells to
achieve proper voltage balance between the individual
units.
Document the progress of the freshening
charge in
Section V of the pamphlet "Operational
Qualification
and Warranty
Checklist", Form 41-7471.
With the load/charger
fuse, circuit breaker or
disconnect
in the "open"
condition,
connect the
battery output cables to the load/charger
circuit.
To apply
a freshening
charge:
Parallel
Connection
of Individual
Battery
Strings
~
When individual strings of batteries are to be
connected in parallel, each of the individual battery
strings should be cabled separately to a common
junction point or box. They should not be .'daisy
chained"
in parallel.
1. Confirm the freshening
(equalization)
voltage
from the charger/rectifier
is set to a value
equal to 2.4 volts per cell X number of cells
connected in series (7.2 and 14.4 volts
respectively for 6 volt and 12 volt batteries).
2. Close the circuit from the charger I rectifier to
the battery system and note that the battery
accepts current.
Each of the individual battery strings output circuits
should contain a fuse, circuit breaker or disconnect
prior to the common connection
at the junction point
to protect the wiring and facilitate battery maintenance.
When the separate strings of batteries are to be
initially connected in parallel their open circuit
voltages should be within 1 VDC of each other prior to
making the paralleling connection.
3. Monitor the battery periodically
and note that
the operation is proceeding
normally and that
the current acceptance
is declining,
the
batteries are not overheating
(within :t5 F of
each other and the ambient) and that the
individual battery voltages on equalization
charge are 7.2:tO.25 and 14.4:tO.50 volts for 6
and 12 volt batteries respectively.
Battery
System
Pre-Operational
Checks
4. Terminate the freshening
charge in the event of
any extraordinary
situations or after 24 hours.
Prior to application of any freshening
charge or load
to the battery system the following checks should be
performed as defined in the pamphlet "Operational
Qualification
and Warranty Registration
Checklist",
Form #41-7471.
Initial
"Float"
Charging
Battery Room and General Equipment Checks.
Following the "freshening"
charge the battery system
should be placed on "float"
charge at an average
voltage of 2.25 to 2.30 volts per cell (6.75 to 6.90 and
13.5 to 13.9 volts for 6 and 12 volt batteries
respectively).
2. Battery
Charger
I Rectifier
Checks.
3. Battery Rack/Enclosure
Checks.
Prior to placing on .'float"
charge, assure the
charger / rectifier is set to the proper output voltage.
4. Battery Open Circuit Checks.
