Default Replacement battery cost?

Just courious, does anyone know the retail cost of the battery pack?

I don't expect to keep the car past the warranty, but you never know.

In 3-4 years time battery prices will have dropped substantially

Also depends on if Fisker plans on offering upgrade deals based on the life left in the original battery. Obviously if they do, a serviceable battery will get a bigger rebate than an unserviceable one. Depending on how difficult they are to replace I was looking at the idea of seeing if someone would make aftermarket packs using Toshiba SCiBs for Fisker and Tesla so that they could be recharged using Level 3 in 5-10 minutes.

For SCiB it is possible. Many of the current level 3's are 49kW. But Aeroviroment make several Level 3's 30, 60, 125 and 250kW. So, pound for pound Lithium Titanate is about half as energy dense as other lithium chemistries, but because of its resistance to DOD damage one can take it from 100% to 0% unlike the Chevy Volt which goes from 80% to 30% if I am not mistaken, using only 50%. Well, that makes up for being half as energy dense right there.
I am still unsure what Fisker's actual DOD is. Assuming it is the same, a Lithium Titanate battery of the same weight would only be about 10kW give the same range and recharge on a 250kW Level 3 charger at 25C in 2.4 minutes.

Tesla Model S 40kw, 60kw, and 85kw nLTO replacement batteries at 20kW, 30kW, and 42.5kW would recharge in 4.8 minutes @ 12.5C, 7.2 minutes @ 8.33C, and just over 10 minutes @ 5.88C. Tesla's ranges for its batteries are probably based on 100% DOD, so instead of 160, 200, and 300 miles, you will get 80, 100, and 150.

Which would you rather have for a cross country trip:
Tesla's Supercharger Access (TSA) = 30 minute charge for 160 mile range on a 85kW battery
or Lithium Titanate Replacement (LTR) = 10 minute charge for 150 mile range on a 42.5kW battery

for 10 hours of travel time @ 70 mph that breaks down to starting with a fully charged battery at start:
TSA: 4.25 hours+0.5 recharge+2.25 hours+0.5 recharge+2.25 hours = 9.75 hours (612.5 miles driven)
LTR: (2.10 hours+0.1 recharge)*4+0.95 hours = 9.75 hours (654.5 miles driven)

Only slightly impressive, but consider the fact that you will probably want that 8 year warranty if you drive like this a lot, and that the LTR will probably last 20 years like this.

I think the A123 site shows that the batteries have a 100% DOD cycles in the thousands.

I'm still wondering what the replacement cost will be. Yes, they will go down in price, but with inflation and limited production run cars it may go up.

Sorry to be a bit rude, but what is the replacement cost for the motor in your 2006 Ford GT? IMO, it is not something we consider when owning an ICE car, nor should it be a concern for a PHEV with a claimed 10/100,000 life for the battery.

You should get one of these if replacing a battery is an issue:

HaHa - The Ford GT engine is only about 20 grand for a new one. The Ferrari is the one I hope never blows... it runs about 45 g's!

I'm just curious about the battery cost.

ffcars,
Since it is warrantied, it should not matter for 50 months after buying the car. As for after that, anything anybody tells you now about the price of a newly emerging technology is going to be wildly inaccurate. If someone told you $20k would it really mean anything? Especially considering that the replacement could have greater performance.
