850 Cold Cranking Amps vs 710 CCA
So I went to replace my battery and specifically asked for an 850 CCA/1000 CA, to replace the battery that's in the truck now. Stupid me trusted the guy and sure enough when I got home it was a 710 CCA!
I replaced it anyway, but the truck wouldn't start! It was turning over fine, but wouldn't catch! So I swapped back in the old 850 CCA and it started right up! Is this just s fluke, or does the engine really need an 850 CCA battery? It's a 1971 Chevy Cheyenne, 3/4 Ton, 2wd with a 400 SBC bored .30 over, with a 400 Turbo Trans. Thanks, Rick |

Re: 850 Cold Cranking Amps vs 710 CCA
Did you check the voltage on the new battery? CCA is cold cranking amps, I can't see how a lower number wouldn't start your truck unless is was really cold out. I got a battery almost dead brand new once, need a little boost to get the car running and the new battery charging.

Re: 850 Cold Cranking Amps vs 710 CCA
Thanks for the reply.
I know! It doesn't make sense! Unless the guy I bought the truck from put on a high torque starter on there, or the connections at the sarter are corroded, I'm stumped! Rick |

Re: 850 Cold Cranking Amps vs 710 CCA
Batteries loose their charge over time, it is possible to buy a brand new battery that needs to be chaged. A parts guy worth his salt would have checked it before letting you out the door.
My vote is to take the battery back and get a refund, you wanted 800+, and didnt get it.

Re: 850 Cold Cranking Amps vs 710 CCA
Masterbeavis,
Yes, I agree and that's exactly what I did...I brought it back! The guy ended up apologizing, and he has ordered an 850 CCA battery for me, which he will sell to me for the same price. I pick it up over the weekend. Thanks, Rick |

Re: 850 Cold Cranking Amps vs 710 CCA
As CCA goes you should have a minimum of 1 CCA per cubic inch to start an engine when it's about room temperature. For very cold climates a minimum of 2 CCA per cubich inch is the bare necessity. A 900 CCA battery will start my truck with a 350 in well past 40 below zero. A 900 CCA would however just barely crank my Dad's 454 over in sub 40 below and actually starting at those temps was hit and miss. For high compression engines the requirements are higher and for engines with gear reduction starters the reqirements can be lower.

Re: 850 Cold Cranking Amps vs 710 CCA
What shop did you buy it from. The battery will have a dote code on it and also will have a stamped date code in the case. The battery could be an older battery and have sat on his shelf for a while. Batteries are like milk, they will go bad after a while. I use to be a regional manager for Exide Batteries and you would not believe what goes on in that industry to get rid of old product.
