How many cold cranking amps do I need for a diesel truck?

In our opinion, diesel batteries should have a minimum of 800 cold-cranking amps (CCA) — and that’s if there are two of them. A single battery should have at least 1,000 CCA and a lot of reserve capacity, something like a Group 31 battery.

At what percentage of CCA should vehicle batteries be replaced?

I’d wait for 50% unless you live in a very cold area… CCA ( cold cranking amps) is rated to start a cold stiff engine in freezing conditions… You barely need 1/4 of that amp rating to start your engine on a normal day… I’ve had cars in with less than 30% of their CCA left which started the engine effortlessly…..

Do higher CCA batteries last longer?

Today’s batteries are smaller and have more CCA capacity/rating than the original battery that came with the car many years ago. Batteries with significantly greater CCA rating appear to last longer, especially if used in winter (with near freezing to below freezing temperatures)
