Description
The EnerSys 24 volt 5 ampere-hour Sealed Lead Acid Battery, covered by this
Maintenance Manual (Ref. Fig. 1) is connected to the Flight Controls DC Power
Supply Assembly to produce fill-in power to its Flight Controls DC Bus while switching
between permanent magnet generator (PMG), transformer rectifier unit (TRU) and Hot
Battery Bus Sources.
The Battery consists of two 12-volt Sealed Lead Acid monoblocs connected in series,
enclosed in a metal outer case, which incorporates the battery main terminal
connector.
Each Monobloc incorporates resealing safety valves to guard against the effects of
abusive use of the battery.
As the EnerSys Flight Controls (FC) battery is sealed, there are no restrictions as to
transportation. The batteries are classified as non-hazardous cargo when transported
by air, land or sea.
