Checking VAC Internal Backup Battery (not applicable for all VAC types)
A VAC’s internal backup battery preserves configuration settings and recent activity data when a VAC loses power (e.g.
during vehicle battery charge/ swap). If this backup battery discharges completely, the VAC will lose some of its settings,
including access control authorizations. The VAC must be fully synchronized with the system database to resume normal
operation. There is a diagnostic error code that displays when the backup battery has a low charge. However, if you
want to proactively check a battery to ensure it is charging, a Maintenance operator must perform the following:
1. Log into the vehicle.
2. Select HARDWARE.
3. Scroll down to the second
page of the menu screen.
4. On the “Hardware” sub-
menu, select BACKUP
BATTERY.
The VAC screen provides the battery condition of Charged, Charging or Not charging:
Charged
Battery is fully charged.
Charging
Battery is not fully charged, but it is charging correctly and
should be fully charged within 30 minutes.
Not charging
Battery is not charging correctly. Contact PowerFleet’s Support
team.
