I never get the battery saver message anymore.

The 12 volt power ports stay powered for 70 minutes after turning the car off instead of shutting off immediately.

I can turn the radio on, with the car not in run mode, without it immediately triggering the battery saver function.

There is no longer any chance of sulfuric acid coming out the vent and dripping on my garage floor.  (It's a maintenance free battery but it is not a sealed maintenance free battery).

My battery won't be destroyed by a low charge level because it's an AGM battery and not a wet cell lead acid battery.

 

I had this exact same problem with my 2010 Fusion Hybrid except it didn't have the battery saver protection, it just let the battery die.

This article says the 2014 Fusion with 1.6-liter EcoBoost four plus Auto Start-Stop has "a more powerful 12-volt lead-acid absorbed glass matt (AGM) battery".

Wonder why they didn't put an AGM battery in the FFH?

Because it costs at least twice as much as the one they install.

Can you just buy a correct replacement battery to solve the problem?

 

Making a higher capacity battery fit is difficult....at best.

 

Even deep discharge designed ones don't like to be LEFT low for long periods.

 

The best solution......IF your driving patterns are one of the few that actually HAS a problem......is an automatic maintenance charger applied at least once a week, or continuously during long periods of non-use.

 

And finally.......if you aren't having a problem yet AND you drive your hybrid at least 10 miles every 3 days or so AND you don't leave it sit unused for weeks at a time......then there likely is NOTHING to worry about.

Are you really sure that they didn't ??

I would look......if it wasn't such a pain in the butt to get to.

 

And if the usage pattern is such that the battery consistently stays low on charge, the AGM won't really solve the problem, it will just prolong it a bit before the battery fails completely.
