What is the acceptable level of battery health for a pre-owned i3?

[sherlockHOME]

Greetings, everyone.

Thank you for taking the time to read this, and I apologise if a similar question has been posed before.

I have no prior experience of owning an electric vehicle, but I am now considering purchasing my first one, namely a 2019 i3 model equipped with a 120Ah battery.

I used instructional videos on YouTube to get the Batta Kappa battery health assessment, which revealed a value of Batt.Kapa.max 36.4.

However, I am uncertain about whether this figure is considered favourable, unfavourable, or within the expected range for a 5-year-old i3.

Any more advise from others would be very welcomed.

Thank you very much

Utilise Bimmerflow to scan it, since it use genuine battery ECU data, ensuring a high level of accuracy. A result of above 95% would be considered satisfactory. Alternatively, you may get it inspected at a BMW dealership. Pose your inquiry on the speakEV forum, where a greater wealth of expertise may be found.

Thank you for your response and guidance, it is really appreciated!

I was previously unaware of talk EV, therefore I will visit their website.

Thank you.

The carscanner application should also display it. (performs optimally on my Honda hybrid)

I would not anticipate a 95% performance level from a vehicle that is five years old, to be honest.

Indeed, Speakev is an excellent place where you may expect to get a conclusive response.

Bimmerflow analyses cell health data, which is mostly determined by distance travelled, to provide relatively accurate results. There are several instances of electric vehicles (EVs) that have travelled 200,000 miles while experiencing around 12% reduction in battery capacity. The speed of charging, the number of charges, and other factors all have an impact.

What is the current mileage of your i3?

Thank you for providing information on Bimmerflow.

The i3 I am considering purchasing has a mileage of little over 30,000 kilometres.
