Decided to replace the engine batteries. Instead of 8Ds I am installing group 31. The 8Ds are 1400 CCA and the 31 is 950 CCA. The battery compartment will handle 3 group 31 where the 2 8Ds were. So out with 2800 CCA and in with 2850 CCA. Big difference is I can still handle the 31s. 8D have out grown me.

Has anyone else done this and what are the long term problems? My biggest concern is cold weather starting, but then I avoid that situation if at all possible.

BTW at Sams club 8Ds are now $180 x 2 for $360. Group 31s are now $100 x 3 for $300.
