3.4.2.1
Internal battery option (S0431B)
This battery allows to maintain the operation of the GenPro 25e in case of absence of its external power
supply.
The internal charging circuit keeps the battery charge permanently from the external power supply.
When the battery is completely discharged (discharge threshold of EasePro),
120
mn 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 and the mode of use of the GenPro 25e (attachment in
GSM/GPRS, Inputs/Outputs, RS232 connected...).
As an information, the autonomy is around 5H with the following conditions:
GSM attached to GPRS network without data transfer.
Serial link not connected.
No input output connected
In the case where the software management of the battery guarantees that the voltage V
BAT
does not fall below 3,55 V, with a battery having 3 charging cycles and fully charged, the
autonomy is around :
20 minutes in GSM communication - 900 MHz - 1Rx/1Tx, serial link not connected, no input
output connected, at a maximum transmission level.
30 minutes in GPRS communication - 900 MHz - 3Rx/2Tx, serial link not connected, no
input output connected, at a maximum transmission level.
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 allows a reset of the modem.
When the temperature exceeds 45 °C inside the box, 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 Turning the modem OFF.
Table 6 : 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 the fire.
