2.1.4 Initial charge records
At the completion of the initial charge and after the cells have been on
float charge for approximately one week, record voltages of the
individual cells or units, the total battery voltage and ambient
temperature. Retain this information in your files for future reference.
This information establishes one baseline for future reference. Refer to
RS-1511 found in the appendix. Make a photocopy of the form and
use it whenever necessary to record readings taken on the battery.
IMPORTANT: Initial charge records and on-going maintenance
records are essential for review by C&D TECHNOLOGIES sales/
service agents in the event of a problem. Since records can materially
affect your warranty, be sure to maintain clear, signed, and dated
copies.
2.1.5 Warning labels
C&D TECHNOLOGIES, INC. provided a warning label to assist in
maintaining standby batteries and to advise you of certain hazards.
This label may be found on the battery cover visible to anyone in
the immediate vicinity of the battery. Make certain that all individuals
who could be operating near the batter
y read the w
arning that is
intended to inform the individuals of basic safety practices.

2.2.1 Float charge
The normal charging v
oltage to maintain the batter
y is called
“Float
Charge” and is provided at a potential slightly higher than the full
charged open circuit v
oltage. The over potential is required to main-
tain properly polarized plates within the VRLA battery. Float voltages
ma
y v
ar
y from 2.24 - 2.26 v
olts per cell at 77°F (25°C) depending
upon the frequency and depth of discharges.
Assuming full float service a (6) six cell 12 volt module should
be floated at 13.67 volts +/- .06 volts at 77°F (25°C).
2.2.2 Equalizing c
har
ge
Under normal operating conditions, it should not be necessary to
equalize batteries when charged at the recommended voltage in Table
2. An equalizing charge delivered at a voltage higher than the nominal
float v
oltage is used to restore unif
or
m cell voltage to a battery.
Note 1: Some hydrogen gas may be liberated at equalize charging
voltage.
