SAFETY SUMMARY A. WARNING: LOW CAPACITY HAZARD. Aircraft batteries are certified to have a certain minimum capacity for emergency operations in the event of a electrical generator system failure. Never use a battery that has less than 80% of rated capacity and never “jump start” an aircraft that has a “dead” or discharged battery. B. WARNING: ELECTRIC BURN HAZARD. Lead-acid batteries are capable of delivering high currents if the terminals are shorted.

INTRODUCTION A. Thank you for choosing Concorde! Your battery has been hand crafted to the highest quality control standards for superior reliability and durability. Our quality system is certified to AS9100 which is the highest standard for aviation products. Concorde aircraft batteries provide greater power for starting at cold temperatures, reliable emergency performance and longer life than any comparable product. Concorde has the most extensive selection of aircraft batteries available.
BATTERY DESCRIPTION A. Concorde RG® Series aircraft batteries are made using valve regulated lead acid cells. Each cell is sealed with a pressure relief valve that regulates the internal pressure and prevents gases from escaping. The positive and negative plates are sandwiched between layers of glass mat consisting of glass micro fibers of varying length and diameter. This blend features superior wicking characteristics and promotes maximum retention of the electrolyte.
STORAGE A. Batteries are serviced and charged at the factory prior to shipment. B. To prolong shelf life, batteries should be stored in a cool location, ideally below 20C (68F). C. The open circuit voltage (OCV) of a fully charged battery is approximately 26.0 volts (13.0 volts for 12 Volt batteries). As the battery state of charge drops due to self-discharge, its OCV also declines. D. Batteries should be boost charged when the OCV declines to 25.0 volts (12.5 volts for 12 Volt batteries). E.
TRANSPORTATION A. The battery should be packaged in its original container. If the original container is not available, follow local packaging regulations applicable to the mode of transport. B. Concorde RG® Series batteries are exempt from DOT Hazardous Material Regulations, IATA Dangerous Goods Regulations, and IMDG Code. They can be shipped as non-hazardous by any means when properly packaged.
PREPARATION FOR INSTALLATION A. Remove battery from the shipping carton and visually inspect the battery for signs of damage. Do not use the battery if it appears to be damaged, contact Concorde for assistance. NOTE: Some battery models may have container sidewalls that are visibly bulged out or sucked in. These conditions are considered normal and will not affect the performance or life of the battery. B. Measure the battery’s open circuit voltage (OCV) with a calibrated digital multimeter (DMM). C.
INSTALLATION NOTE: THE FOLLOWING INSTRUCTIONS ARE GENERIC. SEE AIRCRAFT MAINTENANCE MANUAL OR STC FOR INSTRUCTIONS SPECIFIC TO A PARTICULAR AIRCRAFT MODEL. WARNING: LEAD ACID BATTERIES ARE HEAVY, WITH SOME MODELS EXCEEDING 50 POUNDS. USE APPROPRIATE LIFTING DEVICES OR EQUIPMENT. USE BATTERY HANDLES WHERE PROVIDED. A. Remove Existing Battery (if present): 1. Set Master Switch to the OFF position. 2. Disconnect any external power supply. 3. Open battery compartment access panel(s). 4.
CAUTION: USE ONLY THE HARDWARE PROVIDED WITH THE BATTERY. DO NOT USE STAINLESS STEEL OR STEEL WASHERS BETWEEN THE RING TERMINAL AND THE BATTERY TERMINAL. 13. 14. 15. 16. Replace electrical compartment access panel. Update aircraft weight and balance data, if necessary. Perform an operational test. Annotate battery log book with battery serial number, date of installation and aircraft hours (see Appendix B). Document No.
OPERATION A. Applications: Aircraft batteries are used to start engines and auxiliary power units (APUs), to provide emergency backup power for essential avionics equipment and lighting systems, to assure no-break power for navigation units and fly-by-wire computers, and to provide ground power capability for maintenance and preflight checkouts. Many of these functions are critical to safe operation of the aircraft, so the state of health of an aircraft battery is of utmost importance.
E. Open Circuit Voltage: The battery state of charge can be determined (approximately) from reading the battery’s open circuit voltage (OCV). To get an accurate OCV, the battery needs to be stabilized on open circuit (no charging or discharging current) for at least 4 hours. Once the stabilized OCV is measured, the state of charge can be determined from the following table: Table 2. State of Charge versus Open Circuit Voltage Open Circuit Voltage State of Charge (%) 12V Battery 24V Battery 12.9 or above 25.
H. Cold Weather Operation: In cold climates, the state of charge of the battery should be kept at a maximum to prevent freezing of the electrolyte. A fully charged battery will not freeze even under the coldest weather conditions, but a discharged battery will freeze even when moderately cold. Table 3 gives the freezing point of electrolyte at various states of charge.
I. Ventilation Systems: Airplanes are often equipped with a battery ventilation system. The ventilation system provides for removal of gasses and acid fumes from the battery via vent tubes on the battery case. Ventilation systems are usually a necessity when flooded type batteries are used, but the amount of gas and acid fume generation is minimal from Concorde RG® Series valve regulated batteries.
SERVICING A. Charging Battery While Installed: Batteries may be charged while installed on the aircraft with the following restrictions: Battery charger meets the requirements specified in the CMM or it is specifically approved by Concorde. The battery compartment is well ventilated.
DISPOSAL A. Concorde RG® Series batteries contain lead, sulfuric acid, and other hazardous materials. Never discard batteries in the trash or in a landfill. B. The battery materials are 100% recyclable. Dispose spent batteries and assemblies in accordance with local ordinances and regulations. C. Some RG® Series batteries have outer shells made of aluminum, steel or titanium. These outer shells must be removed before the battery is sent to the smelter.
APPENDIX A – GLOSSARY Active material - Electrode material which produces electricity during its chemical conversion. AGM - Absorbent glass mat used as a separator material between positive and negative plates. Electrolyte is absorbed and held in place by the capillary action between the fluid and glass mat fibers. Battery - A combination of two or more chemical cells electrically connected together to produce electric energy.
End of life - The stage at which the battery or cell meets specific failure criteria. End Point Voltage (EPV) - The voltage at which the discharge current is terminated when measuring battery capacity. Sometimes called cutoff voltage or voltage end point. Unless otherwise stated, the EPV is equal to 20.0 volts for 24 volt aircraft batteries (10.0 volts for 12 volt batteries).
Rated C1 capacity - The nominal capacity, expressed in Ampere-hours (Ah), obtained from a fully charged battery when discharged at the one hour rate to the specified end point voltage at a temperature of 21 - 25C (70 - 77F). Self discharge - The decrease in the state of charge of a battery, over a period of time, due to internal electrochemical losses. The self-discharge rate accelerates as the temperature increases and as the battery ages.
