Buy yesterday a 1.6 l DIG-T 4WD [MR16DDT].

AA first question:

When drive in eco mode, the voltage in the Electric System is lower than normal?
I put a voltmeter and it Mark 12,2./12,3 v in Travel condition.

Tanks.

The alternator on the Juke is “smart” and only feeds voltage as needed. ECO mode probably limits other electrical components so less is needed

One possibile answer(no blow in the wind😜)
The battery is solfatated...
I put the chargbatt, 80% of capacity & over 3,5 A of absorb...

Right. Tanks

Read now from owners manual:

variable voltage control system measures the amount of electrical discharge from the battery and controls voltage generated by the generator.

The ECU has control over voltage output from the alternator. yes. Unfortunately this makes these alternators die when any abnormal load is put on them, like higher spark demand or sound system. You can upgrade to an independent alternator that is self-regulating. Those can be found here: LS Alternator Conversion
