I don't currently own a Tesla, but I am considering purchasing one. I would like to obtain some objective information regarding the Tesla battery packs. Normally each time any battery is charged, the capacity/life of the battery is lessened by some amount. What is the effective life of a Tesla battery pack? What is the cost of a new Tesla battery pack?
 
Search here. Too much to cover.

They can last 400k miles if you drive them normally, and charge correctly. (maintains about 80% of range? 70%? IDK, who cares. At 400k miles if it only has 1/3 range left, it will still be a great 2nd or 3rd car at your house. By then, you'll be able to get an after market replacement battery pack for a few k$ and keep driving.)

If you can afford a Tesla, get a Tesla. No other company even comes close to battery thermal management or charging network. No question about it. I work on engineering teams for battery packs for stationary storage, ebikes and scooters for large companies you've heard of. Get the Tesla.

Welcome to the forum. As @OxBrew mentioned, lots of threads and info. Tesla is best in class for battery and thermal management. One question to ask yourself.

Do people think about how long an engine or a transmission is going to last when they go out to buy a new car? If so, they are probably going to look at the warranty. For the Model Y, the battery and drive unit are warranted for 120,000 or 8 years.


For historical purposes, Tesloop, a Tesla only shuttle service published some details here after 400,000 miles and 3 years on the Model S.

In the real world, Tesla claims the battery in one of the premium Tesla Model S or Model X cars will retain an average of 90 percent of its capacity after 200,000 miles. But Third-party data shows a similar story. An April 2020 study from Nimblefins, using user-submitted data from Model S cars made between 2013 and 2019, found these cars lose around one percent battery range per year.
 
Like Tesla’s official data, Electrek noted that the battery capacity dropped off early in the car’s life, before declining less dramatically in subsequent years. It also found a more severe decline between 90-kilowatt-hour packs and 85-kilowatt-hour packs, though the reason why is unclear.
 
Batteries basically turn chemical energy into electricity. Too cold and the reactions slow down, reducing performance. A warmer battery performs better, but too hot and reactions will speed up and degrade the battery.
 
An easy way to estimate, as far as Teslas go, is to switch it on and check the range.

1.Charge the car to 100 percent battery.

2. Switchh on the vehicle. The car should estimate the range, located in the bottom left corner of the instrument cluster on the Model S and X.

3. Divide that by the original battery range and multiply by 100 to work out how much capacity remains.
 
The main reason it’s hard to judge how long an electric car battery will stay on the road is that they simply haven’t been on the road for that long - the Tesla Model S only launched in 2012. For the Tesla Model 3, released in 2017, the company’s warranty covers the first eight years or 100,000 miles on the entry-level model, whichever comes first. If the battery capacity during the warranty period falls below 70 percent, Tesla covers the necessary repairs.
 
Tesla battery replacements, including labor, tend to cost a bit more:

1. Between $13,000 to $20,000 for a Model S premium sedan

2. At least $14,000 for a Model X premium SUV

3. At least $13,000 for the Model 3 entry-level sedan

4. A similar price for the Model Y compact SUV, but as the car only launched in 2020 it’s too new to say for sure
 
There’s the Tesla warranty that covers packs that degrade at high speed.

The battery’s high price is one of the main issues around whether electric cars can replace traditional vehicles. A longer overall lifespan will reduce the need to replace the battery, but a cheaper pack would make both the initial price and replacement cost less painful.

Fortunately, the industry has made big progress in reducing prices. Average pack prices are expected to reach around $100 by 2023.
