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.
