Dynavolt offer an advanced range of sealed batteries that utilise real gel electrolyte, rather than liquid. This Nano-Gel is able to fully cover the active material in the batteries all of the time, providing a larger effective surface area and prevent the laed from sulphation. The nature of Nano-Gel provides maximum holding to the plates, which is able to withstand severe vibration and prolong battery life. With this technology, they have taken some of the most popular conventional battery models and developed upgrade batteries for these models. These upgrade batteries offer improved battery life and and performance over the originals, as well as being factory sealed and activated.
