When the battery option (S0431B) is present, the tension available on the pin 13 of the 15-pin
sub D HD is
* The min. 2.8 V is the limit of auto protection of the battery. From this moment, the battery
puts itself in protection, and the output voltage becomes null.
When the battery is not connected, the output voltage is de 4.4V ≤ Vout ≤ 4.5 V as long as
the power supply +VDC is present
