Hybrid Battery Degradation?

Hi y'all. Kinda new to this, so I appreciate the patience! I've had a 2014 Ford Fusion Energi PHEV (Titanium) for 6 years now and it's been fantastic. I've got around 116,000 miles on it now and have loved every minute of it! Planning on running it into the ground before getting a Maverick or a used Tesla.

I digress: the hybrid battery may not be what it once was. (which is to be expected) I guess I'm wondering if anyone out there has a similar year with similar miles and what your electric range is at this point. If I'm not mistaken, mine (new) started at 20ish or something like that, but now when I plug in, I think I can really only get up to 12 or 13, maybe 16 miles if I'm lucky. And they go QUICK. The first couple of miles are eaten like they're a snack haha.

Is this a normal rate of degradation? How much is a battery upgrade? Would that even be worth it at this point? Honestly just looking to find some similar owners and similar situations on the threads. Just happy to be here!

I don't know if this is true for 2014 Fusion Energi, but the 2010 through 2012 Fusion hybrid batteries were artificially aged.
Please see this thread:

My instructions on restoring the hybrid EV function on the Ford Fusion Hybrid approaching the 8/9+ years mark.

So you're getting pissed off at the Hybrid function, not working correctly anymore as it once used to, or very rare instances of it working, but not the way you've been used to anymore. It basically makes hypermiling near impossible. That is because Ford has programmed into the car's hybrid syste...

I performed this fix on a couple of fusions with forscan, and the results were instantaneous and impressive.

Whoa! That's crazy. Thank you so much for reaching out.
So if I understand it correctly, they intentionally limited the battery?

Yep, and you have to wonder if they did it or something similar to other vehicles as well.
I own a Ford Focus Electric, and I cannot find a similar aging parameter for my car.
But earlier Focus Electrics have self-destruct batteries. I am knocking on wood that mine don't.

If you are the techy type, a small investment into forscan and the communications cable can provide a helpful tool in understanding the function of your vehicle.
