I bought the Antigravity Jump Starter - very nice product, about $100.
However I have been intrigued about using one of their lithium iron batteries when the 12 v dies - anyone using these?

This is what I purchased:

There's one a little cheaper but I wanted all the attachments; fits perfectly in the center console.
I spoke to a person at AntiGravity Batteries about their current products and the Leaf, and he stated that their current batteries are made for starting. As we all know, this is not needed for the Leaf. He did say that they are working on a Leaf-specific battery that will pack a lot of AHs...
I never let them get that far. My approach is real simple:
As I talk about the car, I ask whomever I am speaking with "How much of your driving is within a 15 mile radius?" Invariably it's between 90 to 95%. So why have two gas guzzlers to go local? For any two car family in a suburban area...
I saw your battery post in some other thread - elegant but very expensive solution. I've been looking at these li ion batteries:

The weight savings is incredible - biggest battery weighs 5 pounds!
According to the Service Manual, the "dark current" should be 50 ma or less (May be for late 2013 models). This means that (if my math is right) a fresh 24 AHr battery should last for 20 days; cut that in half and let's say 10 days. If your battery is older, it will not hold as much charge as a...
After looking around and thinking about it, I decided to spend the money for this one:

There are clearly cheaper ways to go, but the...
I would be surprised if everything that was on would boot up in one shot - normally you would have a staggered start sequence, so the computer would boot up first, then some pre-determined priority sequence would kick in. I'm guessing but I doubt that the start-up draw would be more than 2 amps...
