  • Yuasa YB9-B Powersport Motorcycle Battery is rated 4.6 out of 5 by 11.
    Rated 5 out of 5 by from good quality product The battery needs to be filled with acid and charged before use. Instructions for filling and charging were clear and the bike started on th first press of the button.

    Rated 4 out of 5 by from Works well so far! The battery comes with its supply of acid which needs to be carefully poured into it to activate. Instructions are clear. You can use the battery about twenty minutes after activating with acid, or (preferably) after an overnight slow charge. Just make sure the box/battery is sealed if you buy one of these, as mine had been opened (I only noticed at home and would have taken back if I had the time). It has worked fine so far - but only time will tell whether it is a good battery (i.e. that will work for years).

    Rated 5 out of 5 by from Great quality/value for money As the title says, this is a great little battery (purchased for my Vespa PX125) Easy to set up and fit, the box contained everything I needed. Couldn't really have asked for better.
