We have a pretty good idea how EV packs decay. This isn’t a new technology. Google searches suggest 1-2% decay per year. So a 15 year old car would have 70-85% of original range.

For pack replacements I don’t know, however it seems unlikely you’d really need to. The battery will almost certainly outlast the car. Range will be degraded but I don’t see a lot of 2005 vehicles doing cross country trips either. Even a degraded EV will be useful in town. Many people only drive a few tens of miles a day.

The cost per mile is a simple calculation. It’s a function of your local electricity prices.

"In our 2023 reliability survey, 17 percent of 2013 Tesla Model S owners told us their cars needed battery pack replacements at a cost of $15,000 each."

This is 11-12 years in.

Granted, perhaps batteries were just crappier back then, but 17% is a scary high number for me.

Also:

"This is in line with data from Recurrent, a firm that analyzes and measures EV battery performance, which found that 13 percent of EVs older than 2015 needed battery replacements. By comparison, only 1 percent of EVs newer than 2016 needed new batteries. "

The source of some of the data. What happened with 2020 vehicles?!

What was the remaining range for those replacements?

Tesla makes its own batteries right? When did that start?

Is that high? I have no idea. How many ICE powertrains got replaced at the same time and what did it cost?

Who cares? Spending $15K on battery on a used car is a hard "No!", unless the car is under $10K.

I'm thinking of buying another car next year. $15K is my budget for an ICE car - and only if it has all the bells and whistles. Otherwise it's $12K. Spending another $15K on top of that is ridiculous.

I'd love to know. All I have are anecdotes.

Well I do because I only need to drive at most 75 miles a day and even a car with 30 miles of range would satisfy my commute requirements.

Can you get a better car for $25,000.00? Would you spend $15,000.00 on a $1000.00 car?

The point is that when comparing dollar for dollar, I can likely get a used ICE for the same price that will work out better for me. If I already had an ICE car and was looking for a second car just for daily commutes, the EV may make sense. But the hassle of having to get a rental for longer trips - I don't know if it's worth it. Also have to consider resale value - will people buy the (already used) EV from me if the battery has significantly reduced range? (BTW, in my social circle, I don't know anyone who's bought a used EV - they all buy new ones out of fear) > Can you get a better car for $25,000.00? I have a list of things I want and need from a car. I can find plenty ICE for $15K that matches my requirements. $25K is the max I'll go for an EV, figuring that I may save $10K over about 8-10 years in gas based on the calculators I've used. I can't find even one EV that matches my requirements for $25K. Each one has some problem - too little room or some other annoying problem (e.g. Ioniq 5 not having rear wipers). I can get great ICE cars for $15K. I cannot get a single used great EV for $25K.
