acid batteries are warranted against defects in materials or manufac-
turing or both. To keep the warranty in effect, you must place the units
on charge by the date stamped on the shipping carton when stored at
77°F (25°C). If storage beyond this time is required or storage temper-
ature is in excess of 77°F (25°C), monitor battery voltage at monthly
intervals, if possible. A convenient measurement technique is to read
the open circuit voltage. If the open circuit voltage drops below 2.10
volts per cell from the nominal value, the cell(s) must be given a boost
charge at the “Initial/Equalize” voltage shown in Table 2. With the
exception of the LS 2-600 all units consist of multiple cells. Refer to
Table 2 for the nominal voltage and number of cells for a particular
Liberty Series unit. Never charge the cells at a higher voltage than the
equalize/ boost voltage recommended in Table 2, at 77°F (25°C). If
cell temperature is below 60°F (16°C),
double the initial/equalize
charge time that is typically 12-16 hours at 77°F (25°C).
If this is not possible, contact C&D Technologies, Inc., Technical
Services Department for special instructions.
Always complete a record of initial charge, refresh charges during
storage, and float charge readings as described in
“initial charge”
Part 2, Section 1.2 using RS-1511 of this manual and retain the
readings in your files for future reference. Clearly identify your installa-
tion location, application, C&D Technologies model number, the date,
and name of the person who took the readings.
The service life of the battery will depend on its ambient temperature,
frequency and depth of discharge, discharge rate, charge voltage, and
regulation of the battery charger.
SECTION 3 - INSTALLATION AND CONNECTION
3.1 Location and Preparation
Liberty Series 1000 batteries are best installed upright. Physical
dimensions for layout may be found in Table 2. Install battery in a cool,
dry location away from heat sources. The recommended operating
temperature is 65-77°F (18-25°C). The allowable temperature range
with performance degradation at the extreme temperatures is 32-90°F
(0-32°C). Float voltage compensation should be made for temperatures
other than 77°F (25°C).
Avoid sources of hot or cold air directed on a section of the
battery that could cause temperature variations within the
battery assembly. Such variations will compromise optimum
battery performance such as float voltages of individual cells.
When handling units never lift them by the terminals as this can
damage the post seals and cause acid leakage.
