Just as an FYI, yesterday when my original, 4 year old battery finally died, while I was searching for a trustworthy replacement, I discovered that the OEM Hyundai battery that the dealer sells is an H8/grp49 Interstate battery. The dealers I called wanted about $215 for the battery. I instead went to a local Interstate battery retailer and picked up the same thing for $190.
My other option was an ACdelco H8 battery for $175. I have one of those in my 550i and it has done well for the past year and a half. Figured I would give the Interstate a try though.
