Juniper Systems Allegro DOS Manual - Manual (Page 47)

Hardware Features Page 2-29
When the battery pack voltage drops sufficiently, the Allegro
automatically goes into suspend mode. Charge or replace the batteries
as soon as possible.
The battery pack has enough charge left to retain the system RAM for a
short period of time, at which point the Allegro completely powers
down to prevent damage to the batteries. If this happens, the Allegro
reboots after you charge or replace the batteries. All data not saved to
the disk is lost.
Charging Indicator
When the rechargeable batteries are being charged via the AC power
adapter or the vehicle cigarette lighter power adapter, the LED
underneath the charging indicator is lit. When the batteries are fully
charged, the LED turns off. Note that when the LED turns off, the
batteries continue to receive a trickle charge.
If the charging indicator LED does not light up when you plug the
Allegro into a charger, the battery has a 90% or higher charge and does
not need to be charged. Batteries should be discharged below 80%
before they are recharged for maximum battery life.
