Internal battery option (S0531)
This battery allows to maintain the operation of the
GenPro 425e
in case of absence of its external power
supply.
The internal charging circuit allows to keep permanently the charge of the battery from the external power
supply.
When the battery is completely discharged, 4 h are necessary to obtain a new complete charge. It is normal
if the box is becoming a little bit hot in this case.
The autonomy of the battery mainly depends on the mode of use of the
GenPro 425e
(attachment in
LTE/3G/GPRS/GSM, Inputs/Outputs, RS232 connected...).
In the case where the software management of the battery guarantees that the voltage V
BAT
does not goes below 3,5 V. The autonomy depends on data volume, transmit power and
communication type 4G, 3G, 2G. With a new battery completely charged, the autonomy is
around:
Between 1h and 4h continuous data transfer, maximum transmit power, according type of
communication.
Up to 11h attached to the network without data transfer.
When the battery is charged, it is not possible to do an ON/OFF of the device. Only putting the
Reset input (pin 10 of the 16-pin Micro-FIT connector) to the Ground or sending the command
AT+EGMRST=0 allows a reset of the modem.
Below 0°C and above 45 °C inside the device, the protection of the battery management
triggers. The battery will not be charged.
If the battery is present, prepare the modem for storage or transport conditions, in order to
limit high discharges of the battery. For this, see § 5.2
Table 9 : Characteristics of the polymer lithium battery
The battery cannot be replaced or modified by the user; the device must never be opened.
For any intervention on the battery: the device must be returned to the factory.
Do not throw the modem and the battery on fire.
