what up guys? its time i get a new battery because its all sulfated and keeps dieing over and over and i dont wanna kill my alt. just wondering the CCA of the from the factory nissan batteries? my car came with an energizer with 640 CCA and since i only got $75 or so i can spend on a battery im wondering what the factory spec is...i can get a diehard with 690 for $70 but if the spec is lower than the 640 ide rather spend less money than that on a battery with lower CCA.

thanks

 

You can always use more CCA.

Unless, of course, you have shorted the terminals with a wrench and it's welding your hand to it. Then the CCAs are a little inconvenient.
