Battery Storage and Charging
TDC-0971-011 CCU 100 and Repeater 100 Installation Guide 55
Proprietary and Confidential
State of Charge
The state of charge (SOC) of the battery can be approximated by using the curve shown in
the following chart. This curve is accurate to within 20% of the true SOC of the cell under
consideration, if it has not been charged or discharged within the past 24 hours. The curve
is accurate to within 5% if the cell has not seen any activity, charge or discharge, for the
past five days.
Charging the Battery
You can charge spare collector and repeater batteries individually, or in groups, to save
time.
The charging of collector and repeater batteries requires the following items:
• Power Sonic PSC-61000A-C charger
• Molex 39-01-4046 connector
• Collector or repeater batteries
The recommended method for charging batteries is to utilize the Power Sonic PSC-
61000A-C charger. The Power Sonic charger requires modification so it can be plugged
directly into the battery. This is done by retrofitting the output of the charger to a Molex
39-01-4046 connector with the red wire going to pin one and the black wire going to pin
two of the connector. Follow the instructions that come with the charger for correct
operation.
After charging, the battery should be removed from the charger for at least 24 hours. After
this time the open circuit voltage should be measured to verify it is at or above 6.4 volts.
Note Batteries in storage must be charged routinely for maximum shelf life. For
more information, see Long Term Storage on page 54.
