They make slimmer lighter car batteries? where can I find them. I have a 2004 Hyundai elantra GT 4dr 2.0l?

Call advanced auto parts to see where you may be able to find your kind of battery.They may have one.If not they'll tell you what to do.

well I guess in outer space.

Using your system of forming a question? You do not know what kind of car you have? Statements with a question mark after them aren't really questions? Not sure what you're really asking?

As far as I know, the newer, smaller lithium ion established batteries are not out still for mass intake. I know Nissan is working on some mainly for their hybrid vehicles . It may be a little while before you see them out on the mass market. I linked an excellent article below.

Good Luck.
