Here's some slick kits to make your Parts store battery look like a original Mopar one. I bought a Everstart from Wal Mart that had smooth sides and top.
The kits are shipped from Belgium so they will take a while to get there.

UPDATE 1/22. they also have embossed plastic "Mopar" side plates for that original look!
