Model S battery replacement $12,000?

I stumbled on this today and wanted to query TMC to see if the 12,000 number is true...it's not sourced in the article. the money shot is below (emphasis mine):

Tesla’s Model S 85D has virtually no maintenance because its electric engine has far fewer moving parts than a regular internal combustion engine. The battery is guaranteed for eight years with unlimited miles and, after that, is replaceable for $12,000. The vehicle comes with a limited warranty and $600 yearly inspections are optional.

Has anyone seen an actual price from TM? Has anyone ever bough a replacement? I am interested in this because I believe it's a big factor in determining a long term cost/owning strategy.


 
The price of a new battery with trade in will be a lot less than without returning the used battery. That is because the old battery can be refurbished relatively cheaply. I think that accounts for the 12k vs 45k prices
 
A long, long time ago (before the Model S was ever shipping), Tesla offered a "guaranteed battery exchange" - i.e., insurance plan. For $12,000 up front when you bought the car, you could have the battery replaced at 8 years, no questions asked. If you needed it sooner, you could get it sooner by paying slightly more; they even suggested if you could delay, you could get a bit of your money back.

From my perspective, a pretty poor deal for an insurance policy, given the uncertainty about the car, the battery longevity, or the third party parts community following 8 years.

I don't believe that anyone knows the "true" battery replacement cost yet, as Tesla adjusts things all the time and only the 60's can exceed their battery warranty before 2020. Don't trust any price of an 85 kWh pack until 2020, because until then the numbers are only good for determining insurance replacement costs.
 
I guess if you left a bad battery and the swapping stations have your info ...they are going to call you and let you know that not only battery is low but also needs replacement...:crying:

So we need to come up with a different idea:tongue:

I hope by the time battery needs replacement ...the cost of battery has come down significantly
 
Where did you see the battery replacement cost being $25? Is that for 85 kWh?

Tesla - I don't think they have posted it anywhere, but you can stop by a store and ask. $25k is indeed for 85kWh, the 60kWh packs are $20k. (I haven't been in recently enough to ask about 70kWh packs).

I've got a 6-year-old battery in my Roadster, and it has a ton of life yet. The Model S battery is built much better, and more suited for its automotive application. While some people may want to upgrade batteries in reasonably new cars, I have a hard time imagining a large number of people buying a new similar battery for an old car. Sure the capacity will go down over time, but the Plug In America battery survey estimates it will have 90% after 100k miles. Just before the Model S launched Musk said the battery was designed for a 16-year life and should have at least 60% at the end (note that all numbers Tesla has given on battery degradation have been very conservative; in real life they are performing better than Tesla's claims so far). That's still far more range than any non-Tesla EV on the market today, and far enough to make it between Superchargers (though you might need a range charge for some of them). I imagine anybody that wants more range in a car that old would sell it to somebody that is OK with that range and buy a newer car rather than put a new battery in an old car.
 
Batteries go bad for reasons other than losing capacity. My Roadster battery was just swapped because of a faulty $.40 sensor. It was covered under warranty but when I asked they said the swap would have cost $5,000 out of warranty. That seems pretty darn cheap for a 53kwh pack but it does involve an exchange in which they refurbished my pack.
 
Yes. I think (?) the focus was on degradation because, as PokerBroker points out, in other cases you don't replace the whole battery.

Note that the hand-built Roadster battery warranty was only 3 years, whereas the better-built Model S warranty is 8 years, so people are less likely to get hit with out-of-warranty costs for such reasons.

If you are replacing for reasons other than degradation you don't pay the full battery cost. Even if Tesla swaps out the whole battery for expediency, they will only charge you to fix what broke. In the Roadster case, they have to hand-rebuild a sheet, for which they currently charge $3,300 plus installation and shipping - people in WA have been charged $4,000, and they get a 1-year warranty, alignment, and a full service with that - and, the battery always has a better CAC. Tesla product specialists says that new Roadster battery pricing should be coming soon; these are the old figures.
 
My Roadster pack has a bad sensor too and is out of warranty so I was quoted in writing the $5000 rate to replace with a refurbished pack. Can not seem to find the sheet with the quote, but it if I remember correctly it was separated into 2 charges of about $2500 each. I think one was labor and shipping and the other was for the battery or the repair of the battery itself. I have opted to wait to see what the Roadster upgraded backs will cost before deciding what to do. In the meantime the Roadster drives normally, has normal range after charging and the service center said that it appeared all the cells are reasonably balanced with each other.
 
The price to replace a sheet (how many cells in a sheet?) seems fairly reasonable. I'd be more concerned about paying $5000 for a refurbed pack just because of a darn faulty sensor tho. Might as well go for Roadster 3.0 while you're at it, no?
 
Is it true that the only diferenve beteen an S85D and a S70D (apart from price and performance differenc) is the price?

The price difference is $10K for a mere 15kWH. If the only thing that worries you is the additional degeredation of the 70kWH battery pack would it be better to keep the $10K and use that down the line for an upgrade? You might even get a 85kWH battery pack in a couple of years for that kind of money...
 
I wonder if a buyer did purchase a new 85kw battery if that would change the economics of the free supercharging? You can make an argument that it would be a known cost for most Model S' out in the population. But when you add that many could have new batteries it could change the economics. Perhaps you will have to re-buy supercharger access with the new battery. Tesla seemed to want to tie free supercharging to the 85kw battery choice.

The 70D has been Supercharger enabled too..
