 DC GENERATION - BATTERIES - DESCRIPTION AND OPERATION
_____________________________________________________
 1. General
_______
 The DC generation is provided by two batteries.
 Each of them has a nominal capacity of 23 Ah.

 **ON A/C 001-049, 051-099, 101-105, 201-203,
 They are mainly used to:
 -start the APU in flight and on ground,
 -supply AC/DC essential network in emergency configuration during RAT deployment and when the emergency generator is not available (landing gear extended configuration).
 Each battery is associated with a Battery Charge Limiter (BCL).
 It should be noted that, in normal configuration, the batteries are most of
 the time uncoupled from the network during the flight.

R **ON A/C 106-149, 151-199, 204-299, 301-399, 401-499,
 They are mainly used to:
 -start the APU in flight and on ground,
 -supply AC/DC essential network in emergency configuration during RAT deployment and when the emergency generator is not available (CSM/G switched off after landing).
 Each battery is associated with a Battery Charge Limiter (BCL).
 It should be noted that, in normal configuration, the batteries are most of
 the time uncoupled from the network during the flight.
