MG5 Battery SOH on Car Scanner

Alb · Jan 31, 2025

Out of idle curiosity, I did a quick check yesterday:

The car is 3Yrs & 7Mths old so when do you think it's going to make the first drop?

Amazing it hasn't already. Whatever you are doing it's working.

This my last SOH reading.

Two thoughts cross my mind
1) Whatever you doing to preserve SoH is working

2) if it’s too good to be true…
I would do a battery capacity calibration charge and take note of the power used by the EVSE during the whole procedure..

This will give a strange result without taking into consideration charging losses, unless anyone knows exactly how to work them out

A successful battery capacity calibration will re-calculate SoH.

Agreed, taking note of the EVSE’s consumption is just a rough guide, not an exact science.

Which app is this using? Got my service in 2 days so be interested to compare the readings. Last reading was 93% so hoping it hasn’t dropped to much from that.

The App is called Car Scanner:

Car Scanner ELM OBD2 - Apps on Google Play

Trip computer+car diagnostic tool with widest variety of features and dashboard!

play.google.com

Not sure about Apple but I'm sure they will have a version too.

You'll also need a compatible ODB II dongle. Searching the forum will bring up some recommendations
