Lead acid batteries are old tech: invented in 1859 they are heavy, full of corrosive acid, and they deliver relatively low cranking amp outputs. Lithium ion batteries were invented more than a century later and are lightweight, deliver high cranking amps, but they are expensive enough to be limited to top-end bikes. The newest battery technology of all are the latest sodium ion batteries, which are claimed to be the Goldilocks of 12V power: lighter and more powerful than lead acid, and cheaper than lithium.
JMT says its new sodium ion batteries will operate over a wide temperature range, can survive deep discharge and can also be rapidly recharged. They have a long lifespan, promising to survive up to five times as many charging cycles as lead acid batteries. The JMT batteries have a built-in charge indicator and come in a variety of motorcycle-friendly sizes with SRPs starting from £16.25.
