Hybrid (HV) battery health

[Anthony Ginn]

Hi All,

My first post here. I'm looking at getting a c350e for my wife, 2016 model. I have a Tesla and Leaf currently and am able to look on the car computer to show me how 'healthy' the HV Lithium battery is - Its a blunt instrument as you cant see the health of individual cells, nevertheless it works.

Is there anywhere i can find the same info on the Mercedes? Keen to find this before i hand over fist fulls of ££ to a dealer.

Many thanks, Anthony

Welcome, that's a good swap if you can do it !

MB Hybrids are a bit of a sore point, I expect you will get some comments shortly...

Ha, thanks... She's not happy about having to leave...

I'm not 100% on this, but I don't believe there is a way on the car to check the battery health. I'm sure the dealers can with diagnostics , however, but just won't tell you as they won't want you moaning at them!

 

[John Laidlaw]

you've now made me wonder whether i have this blunt instrument on my i8...., something to do this afternoon!

Cheers John. Yes seen this. The car is at 52k already, so 10k left on that warranty.

I have never read a good story on Mercedes hybrids.... the few fault that come up here, are big and the dealers never seem to resolve them.

I have a C300h which mild hybrid.

I haven't found anything to show the battery health.

Thanks for all your helpful replies.

I spoke MB and they've advised only at the dealers! So, i've asked for a report and will see what comes back.

C220d is a better car, better fuel economy and much lighter. The battery range is around 8 miles then it eats fuel due to lugging all those batteries around

 

[Botus]

if you already have a tesla why would you ever consider one from Mercedes? yes the leather trim is stitched together all on the **** but the rest of the car is better....

if you are trying to save the planet and drive slowly then Toyota (AKA lexus) make hybrids which are fine so long as your foot never presses more than 20% down on the throttle (so you don't find cvt drone), and the build quality will make a merc look like a tesla...

I have to replace enough batteries yearly as it is!! Going no where near anything else that does., will.

 

[Botus]

on proper car's they get a 10 year warranty for the drive battery....

although as per original post... buried in the small print is the fair usage policy.... which no one talks about. If you smashed it to death with fast charging for 4 years and did 60k miles you aren't going to get a free replacement (how are tesla handling that little bit of fun I wonder?)

I read in some scandanvian towns they take the Toyota ones from old / crashed cars, link 10 together in a shed and use to smooth peak demand on renewables - they think most 7 year Toyota ones have lots of life left

Toyota drive batteries are £7k each - not fitted, at 1.20 a litre and 25mpg to the gallon I made that £7k in to 32k miles worth of petrol... so not as bad as it sounds.... but it sure drives up the cost of your charging bill !!!

I've bought an off grid house here (in Spain) and am looking into this...I can get old car battery packs with 10x the nominal capacity of the new one for the same price. So as long as it stays above 10% efficency I'll be winning. Apparently the Toyota and Leaf ones are the best for this as in this application they last longer than the new purpose built batteries...

Toyota warrants its HV Batteries for 15 years !

HV Health can be checked on Xentry diagnostics.

Leaf cells (gen 2) are more affected by age than mileage, Later cells(gen 3/4) are the other way around

that's remarkable

Merc have an annual get off the hook policy see ** below

looking today - love the clarity on hyundai

Interesting posts on using old Hybrid batteries to store solar. I was pricing at solar battery packs but these might be more financially viable and more capacity if they would work with solar PV. Must read up more on this, thanks Botus and d215yq

For solar, I would chose LiFePO4, they have lower peak current capacity, but much higher cycle life (3000+ to 80% DOD)
