Yuasa (YUAM6219BL) YT19BL-BS Sealed Battery http://www.yuasabatteries.com/ <-- this site has a "battery selector" function available.


I just put one of these in my '03 RT. The Amazon price of $96.19 (free shipping) was just a little over half the price at the local BMW dealer for a comparable sealed AGM battery: $189.00.
