Default Can smart charge be disabled?

Like the title says, can Fords smart charge be disabled?
Basically, it keeps the battery barely charged, and gives you .000000000000000000001 more MPG.
I want it like the 1990's, top voltage all the time.

Watch out boys, he's one of those 14 volters..... I agree, it's not a strategy I understand either.

Aren't you the guy who bought a new truck and hated everything they put on them?


Just sell your truck and buy a 80's carbureted regular cab truck and be done with it.

If I could find a good one I would. They are all gone.
You did not answer the question.
Can "smart" charge be disabled?
PS, there is not one thing about this 2013 I like better than the 1995 I had, but there is a whole list of things I like less about the 2013 than the 1995.
Smart charge and EAPS tops the list.

You should be able to find several in Southern or Western states with no rust.

Sounds like you like to whine.

Anyway, this is the first I've heard that the battery isn't maintained at full charge. My 2012 has the original battery with no issues.

"The concept of Smart Charging is actually fairly straightforward. A battery has the capacity to take a slightly higher-voltage charge when cold, so the ECM charges the battery at a slightly higher capacity when cold and balances the charge rate against consumer loads.

The alternator works at maximum capacity only when absolutely necessary and the battery is kept in a constant (undercharged) and healthy state of charge. Battery temperature is estimated from the intake air temperature sensor, which is a good indication of the temperature under the hood.

Battery type warning: Ford specify a silver calcium battery for use with this system. A conventional lead-acid battery is not suitable."

When I first got this truck, it took two weeks to get the "low battery" warning to go away.
Smart charge is why.

Just disconnect the 3 pin plug on the alternator.
You will have a pretty battery light on the dashboard, but the Smart Charge will be disabled.
