Cost of a new battery?

[uaw1]

I've seen many numbers so what does a new battery cost for the tesla S?

The reason you see many numbers is that the price changes frequently, and there are different battery sizes. It's expected that by the time the battery needs replacement, the cost will be far less than the number you've seen (conversely, the cost will be the same but the capacity will be far higher). Also some costs that you've seen don't include the core reduction for the old battery.

Tesla is now warrantying the batter for 8 years and unlimited miles, so it's unlikely that the actual price for a new battery will be an issue for any owners for a good long time.

Interviews a couple years ago said that the battery cost was about 1/4 the cost of the car; it seems likely that costs have come down some since.

It costs however much you find one for. I've seen 85 revD's as low as $9k, although wk057 paid $20k for three of them. Just depends on what the seller is asking.

I'm thinking about a used one maybe a 09 so battery cost and drive motor cost will be a issue for me.Im having trouble getting a real price on these things.Does the warrenty go with the car or original owner?Ive got so many questions thanks

For a Roadster the cost is $29k. We do get a benefit that the new battery is 30% bigger, but still far from inexpensive.

If Tesla can refurbish or reuse components from used battery packs, it may be possible for Tesla do battery pack exchanges for less than the cost of a new battery pack.

Plus, once the Gigafactory is fully operating, along with the normal technology improvements that affect price and capacity, it's also likely that a replacement battery pack will cost less after 4 to 8 years.

Tesla hasn't provided an official policy for battery pack replacements/upgrades - and as they shift to higher volumes, they really need to address that.

Oh, forget about warranty. It's possible that a different pack won't even be recognized by the car without SC reprogramming. And if you've put an 85 in a 70 car, Tesla will not program it as a matter of policy. It's a pricing decision. (they want you to buy an S85 instead)

Since you are thinking about a used 09 you should really be posting in the Roadster forum, not the Model S battery & charging forum (mods, please move).

Dhrivnak is correct, the cost of a new battery for a Roadster is $29k and is an upgrade from original. Be aware, however, that the data from the PIA Roadster battery study here http://www.pluginamerica.org/surveys/batteries/tesla-roadster/PIA-Roadster-Battery-Study.pdf suggests that, on average, batteries will have 80-85% of original capacity after 100,000 miles. I have about 60,000 miles on mine and have 94-95% of my original range.

Replacement battery from the Teslamotors website:

Now available for all Roadster models.
Upgrade your Roadster to a battery that stores roughly 40% more energy than the original battery. There is a slight increase in the battery weight but the total range increases over 35% from the original Roadster.

The price of the battery upgrade is $29,000, including all labor and logistics, which is equal to Tesla's expected cost. It is not our intention to make a profit on the battery pack. The reason the cost per kWh is higher than a Model S battery is due to the almost entirely hand-built, low-volume (only 2 or 3 per week) nature of Roadster battery packs. It also includes additional work to remove, upgrade, and reinstall the power electronics module (PEM.)
​

Regarding the warranty - if the Roadster that you are looking at is still under (an extended or CPO) warranty, it would transfer to you. Although the discussion about the recent change to the transferability of the Model S warranty would cause me to confirm this in writing with Tesla prior to any purchase.

I get Tesla won't reprogram the battery pack due to pricing decision. I'm curious when you put a larger battery pack into a 70 car, will the car even start up and drivable?

None of us has tried it but I doubt it. Some dude a year or so got Tesla to reprogram, but that was the last one known.

The battery includes a computer that introduces itself to the car computer for what it is. Car computer checks if it knows anything about such a battery an then decides how to proceed.
