    It’s truly amazing how something so small can have so much power. The only turn-off was the price, because it cost more than a car battery. The crazy part will be when you pick it up for the first time. As you’re standing there holding it in the palm of your hand, you’re first thought will be, I got screwed. I’m here to tell you different, because when you take that old lead weight out and put this thing in, you’ll be amazed. I have no problem recommending this brand of battery and it’s all that I’ll use from now on.

    Buy a different battery and order direct from antigravity battery website.e

    Battery was defective and won't hold a charge. Has less than an hour of run time, drained completely during my first ride leaving me stranded. I bought a battery charger designed specifically for this type of battery and it continues to show a code denoting that it won't hold a charge. Extremely dissatisfied with the quality.

    Packs a punch, long after the finish line.

    8 cell Lithium-ion powered Anti gravity battery is designed for racing and special applications. My first battery of this type is 3 years in the running and never let me down. Used for vintage motorcycle racing in a total-loss application on a Honda 350K running electronic ignition I run two practice sessions in the morning and two races in the afternoon on a single charge, if necessary. When used in motorcycles up to 650cc, this 8 cell battery does the job with more than enough power left over.

    AntiGravity batteries are race grade superb units

    I have a couple of these and they are unbelievable. Small form factor to fit in tighter spaces, but include foam padding to fill up the stock location if you are in to that. Weighs a fraction of the original battery. I have one that I've had 8 years that I move from bike to bike and it works like new. I'm using this one in a Ducati 900SS, a bike with a notoriously difficult motor to crank. This battery cranks it hard every time and it starts right up quickly. I can't recommend these any more highly, and I have several friends that I've convinced to try them with similar results.
