Autonomy of an AXL cabinet:
The Aastra XL battery cabinet guarantees:
• 24 hours of autonomy for an empty AXL with a consumption of 16 W maximum.
• 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 40 A.h can guarantee up to 12 hours of autonomy for a maximum consumption of 150 W. It will
be fully charged between 10 and 24 hours. 40 A.h is the maximum capacity recommended for an AXL.
For the battery to be fully charged in less than 10 hours, the capacity of the installed battery should not
exceed 20 A.h.
