Fault Isolation Summary - Concorde RG-380E/44 H Series Component Maintenance Manual

RG-380E/44 H SERIES MAIN AIRCRAFT BATTERY
A. Connect the battery to the constant current charging equipment per Table 101.
B. Charge at a constant current rate of C1/10 (i.e., 4.2 Amps for a battery with a
C1 rating of 42 Ah) until the battery voltage reaches 31.0 volts, then continue
charging at the same constant current rate for an additional 4 hours. The
charge cycle should be continuous when using this method, i.e., no pauses
should be included. However, if there is an interruption (e.g., due to a local
power outage), continue from where the profile stopped and run to
completion.
NOTE (1): IF THE BATTERY VOLTAGE EXCEEDS 31 VOLTS AT THE
BEGINNING OF CHARGE AND THEN DROPS BELOW 31 VOLTS WITHIN
2 HOURS, CONTINUE CHARGING AT CONSTANT CURRENT UNTIL THE
VOLTAGE REACHES 31 VOLTS A SECOND TIME. THEN CONTINUE
CHARGING FOR AN ADDITIONAL 4 HOURS AS SPECIFIED ABOVE.
NOTE (2): IF THE BATTERY VOLTAGE DOES NOT REACH 31 VOLTS
WITHIN 24 HOURS, THE CHARGE SHOULD BE TERMINATED.
C. After the charge is complete, allow the battery to cool down for at least 8
hours or until the battery temperature is within 10EC/18EF of the ambient
temperature, then proceed with the capacity test.
