Does this mean that they will be swappable like a propane tank and you only "rent" the battery or pay a deposit and get that back when you buy a refill? If so this is a pretty big game changer. I hope it's easier than going to a dealership and it means service stations can swap the battery quickly.
This seems like the Better Place strategy. But unlike them, Tesla didn't base their whole company on that strategy. I still think the <i>right</i> strategy is the Supercharger network one, and they need to expand that all over the world as soon as possible.<p>But this swappable battery thing is certainly a nice "feature" and I'm sure some customers will take advantage of it, and it's a decent stop-gap until superchargers are <i>everywhere</i>, which could be another decade or more.
