I see, I understand that my battery can now only achieve a full charge
of about the 70% of a "new and perfect" battery.  I have had only this
laptop for... mmm... maybe two years? Is it ok this level of
degradation?

Anyway, from this values, I would go from ~1:30 to ~2:15. Not bad, but
not as good as I expected...

Thank you!
