Motor Cycle Monthly, the UK’s biggest monthly bike title and FREE in dealers, clubs and biker cafes, took a brand new Shorai LFX18A1-BS12 and pitted it against a brand new Yuasa YT12A-BS lead-acid battery. Check out the video to see how they both got on.

John used an Optimate battery tester during the test, and swears by it as a brilliant tool for checking the state of a battery, as well as the charging circuit, on any bike (or car). Take it whenever you’re buying a bike, for peace of mind or as a great haggling tool!
