7.2.2 Internal battery option
The battery is fixed inside the GenPro 25e. It is connected to an additional charging circuit cabled on the
mother board of the GenPro 25e.
This battery allows to maintain the GenPro 25e functioning in case of absence of its external power supply
(power supply connected on the Micro-FIT 4-pin female connector).
The internal charging circuit allows to keep permanently the charging of the battery from the external power
supply.
When the battery is completely discharged, 3 hours are necessary to obtain a new complete charge. It is
normal if the box heats a little bit in this case.
The autonomy of the battery mainly depends on the mode of use of the GenPro 25e (attachment in
GSM/GPRS, Inputs/Outputs, RS232 connected...).
The internal battery option is not cabled by default and its assembly must be made by
ourselves in our factory (contact us). The option is identified by a label (see § 2.3Modem
labels
If the battery option is present, prepare the modem for storage or transport phases in order to
limit high discharges of the battery. For that, see the § 5.11 Turning OFF the modem
7.2.2.1 Specifications of the internal battery option
The external power supply of the GenPro 25e is from +7,2V to 32V DC. The internal regulator of charge
supplies the 4.2V voltage necessary for the battery charge.
