PRIME is the third worst in the battery degradation. How is yours holding up?

Here's some shots from our 2019's diary:



I guess I've gotten better over time.

Interesting how the history stops at a certain point.

Not that it really matters.

 

I guess the GOM just wanted attention.

I won't be so lucky out here.

But with my average miles / kWh where it is, I'm ok.

 

an individuals car's performance is anecdotal though. What's important is 2 things;

1 - what kind of capacity loss are folks experiencing across the entire fleet at any given mile and or year.
2 - what does the warranty say.

Warranty says, "10 years" .... but it's silent on range/capacity degradation. So it's GREAT that some or many have little or no degradation - but is it acceptable if some / many w/in years 5 .... or 7 ... or year 9 have 25% capacity loss? or 50% loss? or more?

That kind of warranty is meaningless. It's the reason Gen1 Nissan Leaf owners filed a class action, when many of their owners lost good amounts of capacity w/in the first 2 to 4 years. Some car manufacturer's traction pack warranty clearly state what their batteries will still have left (eg - 80%) after 10 years - as they all ought to do.
