A. None. 7 Personnel A. Only personnel authorized by the cognizant aviation authority are permitted to service Concorde aircraft batteries. For aircraft registered in the USA, 14CFR Part 43.3 applies. 8. Shop Verification A. The following sections of this CMM were verified by actual performance: •...
DESCRIPTION AND OPERATION 1. General A. Cell Construction: Concorde aircraft batteries are valve-regulated, recombinant gas, absorbed electrolyte, lead acid batteries. The cells are sealed with a pressure relief valve that prevents gases within the battery from escaping. The positive and negative plates are sandwiched between layers of glass mat consisting of glass micro fibers of varying length and diameter.

CONCORDE BATTERY CORPORATION COMPONENT MAINTENANCE MANUAL RG-390E/H SERIES MAIN AIRCRAFT BATTERY Table 101. List of Test Equipment Description Source Part No. Purpose Electronic Load, capable of constant Commercially Capacity Testing current at C1 ADC and 20-28 VDC Available with EPV termination at 20 VDC.
CONCORDE BATTERY CORPORATION COMPONENT MAINTENANCE MANUAL RG-390E/H SERIES MAIN AIRCRAFT BATTERY 7. Capacity Test Procedure A. If the battery is cold, warm it up to at least 20EC (68EF) before testing. B. If the OCV is 20 volts or above, charge the battery at constant potential per Section 8.
CONCORDE BATTERY CORPORATION COMPONENT MAINTENANCE MANUAL RG-390E/H SERIES MAIN AIRCRAFT BATTERY 8. Constant Potential Charge Procedure NOTE: CONSTANT POTENTIAL CHARGING IS THE PREFERRED METHOD OF CHARGING THE BATTERY. IF THE BATTERY DOES NOT PASS THE CAPACITY TEST, THE CONDITIONING CHARGE PROCEDURE SHOULD THEN BE USED.
CONCORDE BATTERY CORPORATION COMPONENT MAINTENANCE MANUAL RG-390E/H SERIES MAIN AIRCRAFT BATTERY NOTE (2): IF A BATTERY REQUIRES A CONDITIONING CHARGE TO PASS THE CAPACITY TEST, SUBSEQUENT CAPACITY CHECKS SHOULD BE AT THE INCREASED FREQUENCY SPECIFIED IN PARAGRAPH 1 OF THIS SECTION (3 MONTHS/250 HOURS FOR MAIN TURBINE ENGINE BATTERIES OR 6 MONTHS/500 HOURS FOR ALL OTHER BATTERIES).
CONCORDE BATTERY CORPORATION COMPONENT MAINTENANCE MANUAL RG-390E/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., 2.8 Amps for a battery with a C1 rating of 28 Ah) until the battery voltage reaches 31.0 volts, then continue...
