Battery must be charged at a temperature ranging from 0° to +40 °C.
For the GSM models the maximum recommended temperature is +35°C. At higher values the charging may slow down.
Close to the limits of the working temperature, some display and/or battery performance degradation may occur.
When the battery is exhausted, the GSM turns off and it is not working until the battery is charged or changed.
