I’ve been shopping around for an emergency jump starter to carry around in the car. I’ve found jump packs that are roughly a little larger than a cell phone, and produce 1000 amps or more. What is keeping them from being a main car battery?

You can get lithium batteries for cars, but they are expensive, and wear out quickly. They tend do be much more temperature sensitive too. Both to the cold, as to the heat of the engine. The lead-acid battery chemistry is very robust and simple. And in a 1k5 kg automobile, the savings of a few kilo’s is not really worth it.
