    In short, I burned this 600 CCA battery up cranking on it too long. Melted the lugs in the housing. But I bought the 720 CCA battery from a distributor of Antigravity (which is why I had to leave the review here on the 600 CCA page) and it breathed LIFE into my ’07 Harley Street Glide 110 Screamin Eagle. My bike used to be called “Kranky” by the guys cause it was so damn hard to start. Now, with the 720 CCA it fires up effortlessly. These batteries really are amazing and worth the inve$tment. Now I’m not afraid to kill the engine at a gas station with a hot engine cause I know ol’ Kranky will fire up.

    I have a 2005 Bourget with a S&S 117
    I’ve always had cold starting issues with the bike as the season starts to get colder Even with compression releases hard starting. I’ve tried everything from changing batteries to warming up motor with a space heater before riding.
    I ordered the YTX12-20 with 600 CCA
    I was amazed at the batteries light weight
    So far I am impressed. The battery actually gets stronger after the 2nd and 3rd turn of the key.
    Hopefully problem solved
