Depending on how low the battery was to start with, charging a dead one will take about 2 hours. Without the availability of electricity and energy, the development of science and technology and the innovations it spawned would not have been conceivable. Scientists and engineers are always striving to improve upon their previous achievements. Batteries that can charge any gadget are called universal chargers. They are made up of cells and function according to the concept of chemical reaction, releasing energy to help power the gadgets and equipment they are designed for. Clocks, remote controls, communication gadgets, children's toys, etc. are just some of the many electrical items that require universal chargers.
