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. In
some installations, the venting system is eliminated as part of the aircraft
modification when changing from a flooded battery to a valve-regulated battery.
However, if the venting system is present, it should be connected when installing
Concorde RG
®
Series batteries.
CAUTION: NEVER INSTALL AN RG
®
SERIES BATTERY IN A SEALED OR
AIRTIGHT ENCLOSURE. COMBUSTABLE GASSES ARE EMITTED DURING
CHARGE AND MUST BE PERMITTED TO ESCAPE.
J. Jump Starting: Never "jump" start an aircraft that has a "dead” battery. A "dead"
battery, by definition, will not start an engine by itself and generally has an unknown
state of charge and state of health. A "dead" battery may appear to charge normally
but may require an extended charging time or a special charging method to return it
to an airworthy condition. In the event of an alternator or generator failure, the
battery may not be available to support the required emergency loads. To be on the
safe side, always remove a "dead" battery from the aircraft and perform a capacity
test to verify airworthiness.
