7.2.2 Internal battery
7.2.2.1 Presentation of the internal battery
The battery is fixed inside the
GenPro 53e
. It is connected to an additional charging circuit cabled on the
mother board of the
GenPro 53e
.
This battery allows to maintain the
GenPro 53e
functioning in the 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 charge 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 that the box gently heated in this case.
The autonomy of the battery essentially depends on the mode of use of the
GenPro 53e
(attachment in
GSM/GPRS, Inputs/Outputs, RS232 connected...).
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 that, see § 5.9 Turning off the modem
7.2.2.2 Specifications of the internal battery
The external power supply of the
GenPro 53e
remains unchanged
(from +5,5V to 32V DC). The internal
regulator of charge supplies the 4.2V tension necessary for the battery charge.
