Battery replacement cost question

Battery replacement cost question

For the 85kWh battery Model S version I was wondering what the cost of a replacement battery would be, if in the unlikely event I killed the battery in a way which also voided getting a replacement under warranty.

I know the site says the replacement will be $12,000 now for a replacement after 8 years - (which at 5% interest works out to be $19,500 in 10 years ie 2023) . I gather this is what Tesla believe it will cost them to provide a battery in 2023. What about what it will cost me today for an immediate swap over?

There's really only one way to find out, totally destroy your battery on purpose. If you have an accident which physically damages your battery, insurance covers it. If the battery fails just through use, Tesla cover it. If the battery is damaged then it's probable only some modules will be replaced, not the entire pack, so you would have to destroy every single module to be sure of needing a whole new pack.

The Leaf has been on sale since 2011, and still no price for a replacement pack, because no one has had to buy one.

There have been estimates that put it at 40,000.

On the other hand it would be pretty difficult to kill the battery in a way that wouldn't be paid for by warranty or insurance.
The only way I could think would be by bricking it by letting it become completely discharged and Tesla will do evertything they can to prevent that from happening. First, the car has a reserve of battery after it shuts down that will last a pretty long time so that you can get it back to charging. Second, the car sends out a signal to let Tesla know when it is getting dangerously low on charge and Tesla will try to get in touch with you. There is even a story of a Tesla Ranger coming out to a guy's house to plug in a car that was very low on charge.

I am pretty confident that someone has already driven a Model S out to a barn somewhere and parked it unplugged for safe keeping and in months or years from now they will be all over the media crying they bricked their car and Tesla should give them a free battery.

Yeah bricking the car by leaving it to long while away for work on assignment is a scenario which is of concern. Some pre-thinking should obviously avoid that scenario. That said , in the unlikely scenario that you do kill the battery and it's your fault , it would be nice to know what the cost would be. Hopefully no one ever has to find out the hard way.

My guess was in line with PAceyWhitter estimate, ie about $40,000 .

TM sez the car goes into a deep sleep mode to prevent that. If you abandon the car for 6 months or more, though, you deserve what you get.

Oh no. In 50 years, how will we all participate in antique auto shows?

Ask your taxidermist.

The $40,000 figure probably comes from the story about the "bricked" battery on Max Drucker's Roadster:
