Battery degrading after 16000 miles?

[Mach-Lee]

The parameter in Car Scanner seems to be the same as what the BECM reports in FDRS. If there is a question about battery capacity, there is a capacity check procedure that can be run in FDRS that runs some additional checks, including a short drive. The results will be submitted to Ford and a warranty determination will be made.

The SoH parameter remains the easiest way to keep an eye on the health however. I think pretty much every single Mach-E is still in the 90's, so not bad.

Remembering to keep the battery below 90%, charging daily to minimize depth of discharge, and keeping it as cool as possible will help prolong the heath.

I have no comment on the accuacy. It looks legit but who knows. It is reporting mine at 120%. Basically my range is over epa range by 120%.

Please don't use Recurrent, they illegally spam your FordPass account, potentially causing your FordPass account to get locked or deactivated, and it drains your 12V battery. It's just looking at the range figure which depends on your conditions and driving—not sophisticated enough to make an accurate battery determination.

Yup that instantly started draining my 12v a year ago when I tried it, it was actually impressive how bad it was lol

I thank you for that. It was Something I found and tried. Like I said i didn't know if it was good or not.

95% at 16,000 miles seems reasonable. Especially since you live in a hot state.

Would you consider HVB SOH of 96% at 11,000 km reasonable? Seems a bit much to me… I’m living in Ontario Canada and have had my vehicle since August this year.

I would not be so concerned about a cheap scanner's numbers. Unless you can actually read individual cell voltage and contactor voltage, you will not get a good representation. I am using a Top the top of the line Snapon scanner at a cost of 12K and another 1200 per year in software updates.

That is a very weird flex ... And you can get individual cell data with FDRS (Fords diagnostic software) for a very small fee.

That being said I drive lots of miles and charge to 100% on L2 every night. With 40K miles and 2 years of service, my car shows NO Battery degrading.

That's impossible.

I have seen the battery temperature go above 140 degrees.

That is just incorrect as well unless something is very, very wrong, or your drove your car into a lava pit.

In summary, you might want to look at a cheaper tool because your 12k fancy schmancy Snapon is just taking you for a ride. The $12 OBDII dongles on Amazon read the data from the car, they don't make it up. Fords diagnostic software, which Ford uses themselves, reads the same data.

Here's what car scanner shows for the 2021 MME I recently picked up. Car has just under 40k miles on it.
Don't know how accurate this is, but it shows HVB SOH at 95.5%. Previous owner says they only DC fast charged one time. The rest of the time they used L1/L2 charging and kept it between 20-80% majority of the time with occasional charges to 100% for longer trips.

Mine was 95.5% with 70,000 miles and I DCFC 25% of my 23,000kWh of power bought.

I haven't even been on this site in months. Then I got an email from this. What's your problem? Did you wake up grumpy this morning or what?
I have an FRDS account also. I am aware that it will show individual cell voltage. That reinforces my point. The ecm data is a starting point only. For an accurate reading, you must look much deeper than your dongle.
Lava, that's funny right there. My observation was correct. In the summer, the heat here was mainly over 100 degrees ambient. I routinely saw battery temps at or over 140. Look at the readings from many people posting from their dongles—157 battery temp (as reported by the ecm).

Thanks for the morning entertainment. LOL

Sounds like you forgot to turn off notifications before you left.
