... to bring them back up to 53 kWh capacity. ...
Very good points.We will be Tesla's first customers that need battery replacements, and those battery replacements will be coming as Tesla is trying to sell 20,000 Model eSses per year.
I am going to give them the benefit of the doubt that they plan to offer an upgrade, and at a reasonable price.
I think it is a huge PR opportunity to tell people: yes the battery needs to be replaced after several years, but when you do - the car gets better, and the price is much less than you would have spent on gas.
Selling us the replacement batteries at a reasonable price will reassure Model S buyers that their replacement price will also be reasonable.
When they are selling 20000+ Model eSses and 20000+ Model eXxes per year, making an extra few thousand dollars on 3-400 Roadster batteries per year is not worth the bad message it will send.
If they attempt to gouge us on the price, we need to be very very loud - so they decide not to.
Hey, I was just copying someone else's number. I've got no idea how big the battery is supposed to be. I just tell people that pretty much everything from the seats on back is battery and that it goes 245 miles per charge. My knowledge of the car stops at putting air in the tires. And the only reason I can manage to do that is that I have this neat gadget that combines a tire gauge with a filler. Clip it on and read the pressure; pull the trigger to add air. Before I got this thing, I let so much air out of the tire trying to read the pressure that I never knew what I had.Um, related question, is it 53 or 56 kWh capacity?
Roadster Technology - Battery | Tesla Motors <-- says it's 56
Not trying to nitpick daniel but I thought it was 56, and if it's actually 53 then I'm going to look slightly more stupid than usual when... uh... Well, let's just say "when another small project I'm working on comes to fruition".
I
Do get the 12K option:
- Charge in Range mode as often as we like
- Drive in Performance mode as often as we like
- Laugh at all the places in the manual saying "may affect battery life"
- Have twelve thousand less dollars
With the battery option in place you get a guaranteed second chance, in fact since you already paid for it you (we) would probably be more inclined to work the car hard and not "baby" it: it would actually change the way we drive and use the car. I think that's the real benefit of the 12K option to me.

When I go to use Range mode, there's a little conversation in my head:
"I should charge in Range mode."
"Should I really?"
"Yeah."
"Okay then."
For $12k I can put up with second guessing myself for five seconds, once in a while.
If you are motivated purely by money then, yes, having the battery warranty removes a large degree of future uncertainty about battery costs, up to a decade. Some people attribute an unhealthy focus on money (profit, loss) to the "evils of capitalism," but I say it's the opposite. Capitalism doesn't lead to a focus on money, individual survival instinct leads to a focus on money, with capitalism following suit because individuals are making those decisions. So, philosophical pondering aside, you have the choice of focusing on limited resources instead of money. Money is one of the easiest resources to replace, especially considering the rate at which The Fed is doubling circulation.Don't get the 12K option:
- Feel guilty/extravagant every time you charge in Range Mode
- Never use Performance Mode (seriously - tried it once, felt too irresplonsible)

3) When I charge it in range mode, I drive it in standard mode.
A lot of people will choose the better battery and they will make the money anyway.
Poll..... how many people would buy the better battery before they even need a replacement to get the improvements?
Just curious. Why does this help the battery life? I'm going on a 160 mile highway roundtrip (too close on a standard charge) soon and will charge in range mode for the first time. They did charge my car in range mode while it was getting fixed in Chicago though.
So long as it's not sitting around significantly below a 50% charge, then this is probably a good plan. We've been told that the battery likes to be 'stored' with a 50% charge, but I have not seen details on how close to 50% it has to be, ideally. There's at least the implication that significantly above or below that is inferior.2) When I charge it, I time the charge to be done shortly before I need it so it doesn't sit around full ( even standard full ).
Who is going to pay for the R&D on a battery technology and firmware that is specific to the Roadster and therefore will be guaranteed to have fewer than 2,500 customers? I have a feeling that aftermarket replacement sheets for the Roadster battery might be a highly competitive market, at least based on the number of people who think that it is 'easy' to design the kind of battery system that Tesla has.They should offer a new battery with: 68kWhr, +15% horsepower above 50mph, 150 pounds less weight, increases range to 300 miles, improves 0-60 by 0.2 seconds and the quarter mile by 3/4 of a second.
( I believe this will be possible using 5346 3400mAh cells in a 11x9x54 arrangement, I believe you can pull the same 5C out of them as the old 2200mAh cells and get more power )
They should offer this battery for $20k.
