Can I move to a higher CCA battery?


Topic starter

I have a 2006 z71 1500 Chevrolet Suburban with 210k on it and I want to put a 850 cca in it instead of the 800 cca I currently have in it.  Are there any ramifications to doing this?  Thanks. Smile

As long as the battery size matches you can move to a higher CCA rating battery.

Keep in mind the battery will only work as hard as the starter motor needs.

Thank you.


you will never notice those 50A.

I would say it's also well within "marketing margin"


In 50 + years of driving, I always bought the highest CCA battery that would fit in the engine compartment. Never had any problems.

In subzero Chicago winters, 1000 amps always  started me up!

An alternative you could consider is a 2nd battery.  RVs or wreckers using similar configuration in a 3/4 or 1 ton chassis are equipped with backup battery for high curent draw and/or redundancy.

looks like a fire hazard
