1) It was only powered on and driven for around 4 miles a week
2 ) And charged once every two weeks or so ( maybe once a week, but rarely )
3 ) But used perhaps twice a year to make a 130 mile trip to see family. ( So about 280 - 300 miles round trip.
4) And left to sit in the driveway in hot Texas sun.

If this were an ICE car, 'Aunt Bertha' would still be able to get in that car after 30 years of taking this same trip and still have a running vehicle, nevermind dry rot tires and such.

From what I undestand, churchlady Bertha would only be able to drive her car like that for a few years before needing to replace the several thousand dollar battery, despite the car being virtually new.
Correct ?
( thanks )
No enough info.
What is the age / cycle count of the battery once it has reached 70% capacity? (To have degraded to 70% it has to be very old or have lots of cycles)
What is the battery chemistry? (LFP has roughly double the cycle life of NCA)
What type of battery management system is in the car?

If Church Lady Bertha drives an ICE car 4 miles a week for decades she is going to spend many thousands of dollars maintaining her car because seals and rubber components break down with age and she will go through several exhaust systems from filling it with water every week then letting it set.
