Some Teslas have over 700 cells. Dropping an 1100 pound battery pack down after raising the car up and locating and replacing several cells in an old battery when all the other cells are also nearing the end of their lifespan is a very expensive and timely endeavor for a small amount of extra time before having to do it again, because replacing bad cells doesn't magically make all the other cells new again. Without a complete battery pack replacement in a 10+ year old battery pack, it's just spending a lot of money for a band aid.
... Yes, that's why I said I don't recommend it.
If time is cheap for you (e.g. you're broke) then spend it until you are able to recycle the pack outright.
If you're broke you aren't going to have the equipment or the safeguards to remove and repair a 1,000+ pound battery yourself, and you won't find a shop to do it for less than a couple grand. You're "just do that" is completely unrealistic. Not to mention that a 1.5 to 2% capacity loss every year means your 15 year old car that started off being able to go 250 miles can now only go around 150 miles on a fall charge, and closer to 100 miles in very cold temps.
People make do, luckily at least some of us are creative 🙄
Average commute in the US is about 30 miles each way.
I don't know how else to spell this out, you just never seem to get this: when the battery wears out, you replace it, not for free, but you get an effectively new drivetrain on your car. Your door dents and scratches will still be there, brakes still squeal and maybe you need to replace the shocks. But you can again accelerate hard, go long distances, all quietly and far more reliably than an ice car can. You can do this probably a few times before the body and subframe is worn/corroded too much to be worth it.
Get it?
When a powertrain wears out, a replacement ice will cost a person $2000 for an engine and $1600 labor. That 300 lb engine could sit on a shelf in a warehouse for 5 years or 30 years and still be an engine that works well. You want to spend a few grand more and you can make that old engine that's in working condition, essentially brand new.
You leave a 1000 lb battery pack stored for 5 years and left alone it's ruined. 30 years it's ruined no matter what. Can't just be pulled from a junkyard and taken home. It's too large and heavy. Cost an arm and a leg to get delivered to an independent shop. Not to mention the equipment needed to manipulate around 1000 lb battery packs, so no one can self replace these things. The packs can't be made new. They degrade with age, used or not. They cost more and they lose more value and only people with a house and garage can conveniently charge them.
None of what you're saying is relevant to my point. You can lift the entire frame, using a regular 4 point auto lift, and drop it onto the battery pack slightly elevated off the ground. If you don't have that, a couple of pallet jacks to roll the pack under the car, I mean come on! Where's your creativity?
There are differences between ICE cars and EVs, most importantly tremendous power from zero RPM, & zero CO2 from the vehicle. Why would you think different tech should be equivalent? 🤦
