Battery Group Size for 855D

I might need to buy a new battery for my 855D and was wondering if anyone was able to use a higher capacity battery that still worked in the stock location.

Currently a Group 51 battery is being used with 625 Cranking amps, 500 Cold Cranking Amps and 85 minutes reserved.

Current battery: AutoCraft Silver Battery, Group Size 51, 500 CCA 51-2: Advance Auto Parts#

What group size is everyone using?
