That's just Awesome mipmapped!! I hope some day to get a 2nd life out of my battery as well, heck, I'd drive out to California if that's the place to do it...!
Just out of curiosity, how did you treat your battery over the past 3 years? When did the battery drop down and how long ago was that?

prior to new battery how many miles would you achieve on the full charge?how many would the car estimate at start of trip?

My Fusion Energi is about three years old with 32,000 miles. I am now only getting 4.3 - 4.5 kwh when fully charged and charging only takes 1 hour 40 minutes when it used to take over 2 hours. I took the car in yesterday. When I picked up the car in the afternoon, they said all their tests went fine and that they could not find a problem. Instead they quoted me a "Special Service Message" #45684 which talks only of EV range variables due to temperature, driving style, tires, etc. They seem to be saying that range is variable and too bad.
This in no way answers the concern of battery capacity. I get that range is variable, but for the capacity to drop from 5.8 kwh to 4.3 is not normal. @mipmapped how did you get them to test the capacity?

It took a few visits to the dealer. The first time I got a similar response that you received (no error codes - no problem), so I went back. They then applied SSM 44918 and "reset the lifetime summary", which did nothing. It just resets the computer's estimate of the range. You have to press your case on the KWH, not the range. I believe the dealer then got involved with the battery group at Ford. They asked me to take photos of the dashboard before and after trips to show the energy use. They then ran the "road test with IDS connected" and sent the data to Ford and Ford agreed "the battery is bad" (quote from the dealer) and approved the replacement. I believe the replacement is via the battery warranty not my extended warranty but I can't be sure. It took a few weeks to be delivered. The lead mechanic, Mike Mead, told me they had only replaced one battery before, I believe that was due to a connector burnout on a new vehicle. And this dealership probably sells more electric Fords than any other.
Mike Mead did tell me those with this issue can call him. Look up Ford Store Morgan Hill. Maybe he will regret this now... I'm pretty sure if you could get the car to this dealership they would help you.

Thanks. I will reach out to Mike Mead soon. As for my end, I will probably start building a better case. Were you tracking your kwh on charging (with some kind of metered charging station) or via the logged usage when driving? I want to be armed to show the lower capacity.

I did send Mike screen shots of the myfordmobile trip and charge logs, which show kWh usage. You could do the same or print them out. I also told him that my home charger reported similar charge kWh but I don't think that information is necessary to convince Ford.

Thanks for this info. I've got about 55,000 miles on my Energi now and the most I'm getting out of the battery is 3.9-4.0 kWh. Looks like I'll need to make an appointment with my dealer.

Has anyone else been successful in getting an HVB replacement like mipmapped? I wonder if Ford will change their policy if a number of owners start reporting the same issue. Good job by mipmapped to get a new HVB!!

Finally did the test today. I wanted to run on fairly level ground so reset the trip meter at the bottom of the hill. Touchscreen said 100%, OBD shows the actual battery charge at 95.33% and a battery to empty estimate of 6800 watts, battery temperature at start was 20C (68F).
Trip was done a highway between 55 and 60 mph. When it switched over to hybrid it had gone 31km (19.2miles) and used 4.4kWh. At that point the actual battery charge was 23.28% with a battery temperature of 28C (82F).

So I finally made it to the dealer. Did not go well. All the dealer did was hook up the car to the computer and said everything was OK becuase there were no error codes. He also said that if I was using only 4 kWh then I was driving more efficiently and using less energy. I tried to get my point that this was the total capacity for the battery from full to empty, not how efficiently I was driving, but the Service Advisor wasn't really understanding. They handed me SSM 45751 which basically says driving habits will affect range and that they didn't see any thing wrong with the battery.
I pushed the issue some more on how they would determine if the battery had lost capacity. The Service Advisor said that the next test they would need to do would be to reset the range computer and do multiple road tests resetting it each time, and recharging the battery each time. I said that was what I thought they were going to do they day I took it in. Looks like I'm going to need to take it in again.

I have the same problem - 2013 CMax Energi with about 42k miles; I get about 4.2kwhr per full charge. The only "good" part is that it only takes 1.5 hours to charge on 220 (4 hours on 110). I have about 54 mile round-trip commute for work - mostly highway. I used to get about 24-26 miles out of a full charge, keeping my top speed below 60, sticking to the right lane, and accelerating slowly. To a tank, I'd average about 220 mpg. Now, I manage 17-20 miles to a charge with a tank around 130mpg. And I'm much more conservative to get that number (and I wish I had known how to be this conservative before!).
I don't know when, exactly, the capacity started to decline. Last summer or so, but I figured it was just the summer heat, and my mileage would get better when the weather cooled. Then I saw the threads and tracking my actual kwhr.
I've been "working" with my Dealer's Service group since around December/January. Not much help there. My dealership wasn't "electric certified" when I bought - I didn't even know that was a thing (they certainly didn't mention it). Don't get me wrong, I like my service guys; they're good guys. But they still don't understand kwhr vs. the mile estimate on the screen. They were very impressed with the 20 mpg estimate on the display. They've plugged the car into the computer, found no errors, and sent me on my way. I persisted, so they forwarded the issue to "Ford Central"... who told me 1) pay no attention to the estimated mileage (which I wasn't), 2) reset the lifetime data and come back if it estimates 14 or less (wait - you said pay no attention to the estimate), and 3) the car is expected to get about 21 miles electric (so good on me for getting 20). I can get the estimate to read 14, that's easy - just drive "normally".
I talked with Mike Mead (he's not that far from me, so I was willing to bring it down if he'd see it). He was helpful in that he gave me advice ("Keep nagging Ford"), but he didn't think he'd be much more help: he'd have to go through exactly the same thing my service guys are/will: They can't run the "real" test (whatever that is) without Ford Central's say-so. They don't even know what the test is!
So now, I'm trying to do what I can. I'll start nagging Ford Central myself. Calling the 800 number and making some noise. I'm not optimistic. I really feel let down by Ford and their support of the CMax. I like my car, but Ford doesn't seem to. They don't advertise the CMax (at least, not here in the Bay Area), they don't support their electric vehicles, and they don't even seem to understand them.
I know batteries degrade. Maybe I should be happy that I've only lost 25-26%. I'm not. If everybody's car degraded this quickly, electric vehicles wouldn't sell. Even other CMax Energis aren't degrading like this.
The rate probably won't hold steady, but by year 6 with this car... well, I might as well have bought a plug-in prius.

Where does the 5.8 kwh figure come from? And is the Fusion battery same as Cmax? I have been trying to find where Ford specifies HV battery capacity on these cars but can't seem to find it. My Energi is down to 4.1 kwh when I exhaust its charge, so I'm thinking warranty for mine too.

Ford is going to have a big problem on their hands if this problem is widespread. We are just the first model year owners beginning to notice that there is a real problem. They are also defrauding government and cheating emissions and fleet mpg averages if their batteries only last two years.
