    that is absolutely the opposite of help.

    OP couple things to look at is ah and cranking amps. some will say one is more important than the other. good rule of thumb is have the minimim cold cranking amps as you do RMS. thats a good rule of thumb to start with.

    I read this from somewhere before

    "A good rule of thumb is 100 amps for every 1,000 watts"

    terrible rule of thumb....thats just how much a typical amp pulls from you electrical....some amps more some amps less.....you have to remember AH plays the biggest role when looking for a battery....you first need to start with your alternator and figure out whats its idle amperage is and what its max amps are...then from there u can figure out how big of a battery you need....

    yes but upgrading the battery alone isnt going to solve anything...your alternator should be your first fix....with out it u will drag down ur battery over time

    I don't agree that you should change your alternator first before you upgrade your battery or get a 2nd battery?

    why not? if you exceed your alternator output more than just a little and more than occasionally, then all you are doing is dragging down the battery and overworking the alternator, which has to at least 3x the work to recharge the amount you drain. this is usually death to batteries and alternators. the alternator is where the power comes from, after-all...



    *IF I have forgotten to exchange feedback, please let me know*
    i buy broken amps....
    No, i will not "gift" paypal. please do not even make it awkward by asking. if the fees are an issue, I am usually inclined to add them. unless you have discount elsewhere, shipping is through usps flat rate, through usps parcel post, or through the roof..... i am in alaska. thanks
