MG5 LR SOH at 80%

[sebmar]

Hi all!

I had a 1st service on my MG5 LR and been told that battery SOH is 80%. Done 10k miles so far. Is that something I should worry about?

Yes, the SOH should not realistically drop more than 2.5% per year. First thing to ask is did they measure it right? because that sounds way out.

You can buy a cheap OBD reader and plug it in the cars port to check for yourself.
There are various threads on this just use the search bar.

Funny enough service said it’s perfectly natural. Thanks ?

Will do! Thank you ?

Checked mine the other day and it was still 100% at 2 years old.

Just ordered OBD. I haven’t noticed any difference in charging or range so they must be wrong. I’ll update this post as soon as test it myself.

Maybe they confused SOC with SOH?

Quick and easy test for free is to fill to 100% SOC, reset trips and see what the GOM says (in Normal mode). If it matches advertised WLTP there is negligible/no degradation.
If it shows less for example 245 on a WLTP 250 the calc is (245/250)*100= 98% SOH

Hi everyone! Thanks for all your support which I much appreciate. Panic is over. I’ve used OBD and SOH is 100% … what a relief. I must look for different service as one I’ve used seems to be not good. I clearly asked for it and they said nothing to worry. Also when asked for 3 bottom lines of rear window heating they said its takes longer to heat while I found here it’s actually not a heater at all ?. Once again thank you all!!! Attached photos of service paperwork from service and readings from OBD
