Battery Backups
APs can be configured with battery backups. In the event of a power failure, the battery
backup can provide continuous operation for at least eight hours.
Silver Spring Networks suggests as a best practice, a battery backup within the Access Point.
When operating on battery backup, Access Points maintain full operational features. The
Infrastructure Battery Pack (IBP) uses sealed lead-acid battery technology, which will deliver
energy over a -40 to +85C temperature range. Silver Spring operates the Infrastructure
Battery Pack on a float (that is, the usage model is defined as long periods of topped-off
charge states followed by sporadic deep discharge events (outage events).

, GridScape, or HCM applications can actively monitor status. Events range in
severity from informational (for example, export job succeeded) to warning (for example, the
gap filler has started running because an interval gap was detected), to error (for example,
the DC Detection flag on the meter was set), to emergency. These include an alarm when the
backup battery on an Access Point is critically low.
