  I am by no means an expert, but I seem to remember that the reason lead-acid batteries are good for that particular job is that they can release a huge amount of stored energy in a very short time, which is what you want when you need to fire the ignition of a car. I think other battery types are much more limited in their maximum power output. I am absolutely not sure this is also true for this new type of battery, but it might be.

  Never used it even once. Not even sure I had ever heard of it.
