I just replaced my stock battery with a sub zero. You can not really go that much bigger in batt size but mine is 835 cca. Took care of my lights dimming with power windows to.

The one I replaced my old Interstate with is rated to 1100 cold cranking amps. Seems to be working great.

Get the biggest CCA that will fit the tray.

 

Also, may want to do the Big 3 if you are having dimming issues.
