1. A reserve power supply system, said system comprising:
a first battery;
an electrical interface adapted for being connected to a second battery;
a control unit;
a switch coupled to said first battery and adapted for being connected, to said electrical interface and to said control unit, said switch being controlled by said control unit;
a voltage sensor connected to said control unit and to said electrical interface, said voltage sensor being adapted for measuring voltage across said first battery when said first battery is connected to said electrical interface and providing a voltage sensor signal to said control unit; and
an analytics module configured to analyze said voltage sensor signal,
wherein when said voltage sensor signal is below a predetermined value, said control unit sends a signal to connect said switch to said second battery via said electrical interface.
