Can u use another type of battery in the Caddy CTS 2003 besides the one that same brand that came with car??
U can, but the computer it's going to give u the theft reading, and the car may not start (it happened to me)
sure just make sure it has a ratiing of at least 800CC and the terminals are on the side not top.. if on top when the hood is closed will touch and short your system lol
