    The battery currently in my rig is 630 CCA
    I have a spare one with 875 CCA.....Would there be any advantagages/dis advantages to swapping the bigger battery in?? Is this a bad Idea and will i have to change anything like plug wires/ignition etc??? thanks!!

    Yep!! It's definatly a jEEP thing...So, what your excuse???

    Yes, Bigger is always better. Isn't that why we all own Blazers?
    No, you don't need to chage anything to use a higher CCA battery as long as it fits the space.

    The only real downside to a higher CCA battery is generally they hold less overall power... so basically they usually say for a vehicle w/ lots of accessories like offroad lights, aftermarket stereos, amps, etc etc. you need to use a battery that has enough CCA's to get the job done, but not enough to be overkill and hurt overall power. I didn't check your profile, but I really don't see the need for a 800+ CCA battery if you are in the southern states or anywhere it doesn't get real cold in the winter. No changes are needed if you do swap.... another thing to look at is name brand.... not all brands are equal. A Kmart battery usually isn't as good or will last as long as a AC Delco or Interstate.

    As has been mentioned, unless you are having problems, keep the stock battery size. Won't really hurt to go bigger, but if its not necessary, there is no reason to.

    Short semi related story. Was broke, bought a no-name, no CCA listed battery for my car. Wouldn't even crank the motor over. Bought a name brand (prolly exide) and had no problems. Get what you pay for in most cases.
