MG4 Battery Degradation

One way is to get an OBD adapter (example) and then use the Car Scanner app on your phone.

Interesting. Where do you plug it in?

 

[siteguru]

The OBD port is underneath and to the left of the steering wheel column. There is no cover - if you put your head down into the footwell and look up you'll see it.

 

[SBJames]

Thanks. Will take a look. Just leave it plugged in all the time?

Is the example one you recommend the best (or the one you have?)

 

[siteguru]

It's the one I have, and it works fine.

I've left mine plugged in and had no issues, but some people have reported issues with the car alarm going off when leaving an OBD adapter plugged in. (I don't have it plugged in at the moment - I removed it before my car went in for repairs after being damaged by Storm Eowyn - and I haven't bothered plugging it back in again yet).

Where do I look to see this?

I used a diagnostic tool attached to the OBD Port

You dealer can measure it or you will need to use an OBD2 port scanning device to look at it yourself.

Just decided to check mine again as it's been a while . Now at 34.5 k miles and 26 months 64 kWh NMC battery, SOH 96.8 %. Seems ok to me.

Such as? For what I've researched the two components that are likely to retire your car are either the battery or the transmission. There's nothing else.

The three cars I've seen right through to end of life were retires on entirely different issues. Two because of bodywork, and the third because of a number of issues which together make it an attractive prospect to send it to a scrappage scheme that was in force at the time for £2,000. All of them had functioning engines and power trains at the time.

Glad to see someone else who runs cars as we do (as my parents also did) i.e. buy new and run it into the ground.

I've only sold one on before it was figuratively rusting into the ground, and that was because my senior partner said to me, "I want a new car and under the terms of the partnership agreement you have to have one too, what do you want?" Exit Ferdinand, the five-year-old XR2.

The answer was, "Something with air conditioning, power steering, and maybe big enough to take a bicycle and still close the tailgate," and enter Ariel, the Peugeot 306 GTi6.
