BACKUP BATTERIES (INTERNAL UPS)
LogBox 3
G
is a devi
ce that requires an external power supply to operate. Despite this, to ensure full operation in the event of power outages, the
device features intern
al backup batteries that operate as an uninterruptible power supply. The internal batteries are charged automatically while the
external power supply is present and will automatically take
over as power supply during power outages.
Battery life depends
on the interval between logging, the interval for publication to
NOVUS Cloud
and the number of batteries includ
ed in the
device model. In cas
es where the interval between logs and the publication interval is 10 seconds (and considering that, in this example, batteries
are 100
% charged), the typical battery duration is 2 hours for the model with 1 battery and 8 hours for the model with 4 batteries. For applications
where the interval between logs and the publication interval is 1 minute, the typical duration is 6 hours for the model with 1 battery and 24
hours for
the model with 4 batteries.
When running on bac
kup batteries, the cellular module will be automatically turned off by the device as soon as the battery reaches a level below
1%, thereby prolongi
ng its duration and allowing the device to continue logging. In order for the cellular module to resume operation, the device
must be powered by an external power supply.
The device’s internal batteries are Li-Ion and their chemistry may pose a risk of explosion if exposed to temperatures above or below the device
operating temperatures (see the
Technical Specifications
ch
apter). Moreover, they can only be charged in the specified temperature range (see the
Technical Specificati
ons
chapter). Thus, if the device is operating in an environment with temperature higher or lower than the range spe
cified for
the batteries, it will automatically stop charging the, which can lead to uncharged batteries during power outages.
In addition, a charact
eristic of these batteries is that they lose the charge capacity if they are recharged when the voltage falls below 2 V. In order to
avoid this problem, th
e device will automatically shut down when the battery reaches levels below 3 V. Every battery, however, has a self-discharge
current. In this way, it is important to take into account the storage time with the device turned off. If the battery is stored for a long period of time,
e
specially if it is partially discharged, it can be gradually discharged and reach a point where, when it is below 2 V, it is impossible to recharge it.
We recommend that
you charge the battery up to at least 50 % before disconnecting the device for a long period of time, after which the procedure
for manually disconnecting the device (see section
Navigation Screens
) is performed.
Replacing batteries can lead to risk of explosion. Hence, t
he cover for access thereto is factory sealed and they can only be replaced by the
manufacturer or by authorized technical assistance.
Risk of explosion: Internal batteries may only be replaced by the manufacturer or authorized service provider.
Risk of explosion: Be careful with the device’s operating temperature. Extremely high or low temperatures can cause
ruptures and leaks in backup batteries and cause damage to the device.
