Mine battery voltage alternates between 12.6 and 13.8 Volt. Of course, it is fed by the DC-DC converter so that controls the behaviour.
Our 2nd gen Insight 12V batteries have a tendency to fail prematurely, typically one cell gets out of balance and gets worse and worse until the battery dies.
Keeping it at 14 Volt would prevent that - even if it wastes 20 Watt continuously...
So keep an eye on your battery voltage...!
