Autonomy of an A3XL cabinet:
The Aastra XL battery cabinet guarantees (per AXL cabinet – 3 battery cabinets) 2 hours of autonomy,
no matter the configuration of analogue or digital terminals, but without digital terminals Aastra 5370
and 5380.
Beyond these requirements, a specific battery is required.
One 120 A.h can guarantee up to 12 hours of autonomy for a maximum consumption of 450 W. It will
be fully charged between 10 and 24 hours. 120 A.h is the maximum capacity recommended for an
A3XL.
For the battery to be fully charged in less than 10 hours, the capacity of the installed battery should not
exceed 60 A.h.
