State of Charge
The state of charge (SOC) of the battery can be approximated by using the curve shown in
the chart below. 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.

Charge the Battery
You can charge spare CCU/Repeater batteries individually or in groups to save time.
When charging batteries, there are several items you need:
• Power Sonic PSC-124000A-C charger
• Molex 39-01-4046 connector
• CCU/Repeater batteries
• Molex 39-01-4046 connector
• CCU/Repeater batteries
The recommended method for charging the batteries is to utilize the Power Sonic PSC-
124000A-C charger. The Power Sonic charger needs to be modified so that 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 that it is at or above 6.4
volts.
