Since I can do this, I personally wouldn't buy a retail lithium car battery, but would recommend it to others who are flush with cash.

Here's a marginal example that will start your car easily as long as it doesn't get cold where you live.

You'll have better luck googling "lithium car battery" but beware, the results are all incredibly expensive. If you'd like to inquire about a custom battery that's reasonably priced for whatever capacity you desire you can PM me.
