What have people got away with turning over the 1UZ in terms of CCA? (if possible post ratings at -25 degrees if know)... I am hoping 240CCA at -25 in a dry cell will be enough but I may have to run 2 of them ![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
Below is some analysis on the battery I am looking at and the temperature based on it being in my garage at ambient.
Computed New CCA is 443, a 84.5 percent change.
