A) Yes B) Forscan just has an estimated battery capacity remaining to empty. Alternatively there is an "enhanced" trip meter that says how many kWh/ have been used from the battery. I have used this with a little math to estimate my usable capacity. For example full charge down to 10% battery remain...

There are two things that degrade lithium batteries, age and usage. So to answer your question, yes all lithium batteries degrade with the passage of time. Lithium batteries don't like to be deeply discharged nor kept 100% fully charged. keeping a lithium battery for extended periods of time at eith...

Dobrina, Knock on wood I've only ever head dead 12V battery issues with my FFE. I don't have any problems right now. I googled that error code and found this interesting tidbit. https://ford.oemdtc.com/3487/stop-safely-now-message-with-red-triangle-indicator-dtc-p0a0a-2012-2014-ford-focus#more-3487

To everyone having 12V issues due to the TCU I have found a Pseudo fix. No, I have no solution for Ford's shitty TCU but at least I have found a reasonable way to prevent it from killing my 12V battery. Over the last 11 months since I pulled the F1 fuse I have pondered various ways of powering the T...

Not sure if Steve is still on here so I'll fix it for him. Not sure why since I hate DRLs. Anyway here is a repost of Steve's work with pictures: Okay - here goes.... I started on the passenger headlight assembly. I had already used my 2017 Focus Electric Wiring Diagram Manual to figure some things ...

Did you ever get any resolution on this?

The problem is Ford doesn't want to support this car. After the 8 year warranty you are SOL if the battery coolant springs a leak inside the battery as has happened to several people. A replacement battery is over $20k so not worth it at all. Pretty much after the warranty the FFE is a disposable ca...

My 2014 has always had the battery% available on the sync screen.

Value charging and go times rely on the TCU. Pull the F1 Fuse for a few seconds to "reboot" the TCU. That may help.
