Advanced Battery Systems in the Canadian distributor for ARTS Energy located in France. ARTS Energy produces top of the line Nickel Cadmium (Ni-Cd) and Nickel Metal-Hydride (Ni-Mh) batteries. ARTS Ni-Cd line is mainly used for applications with high power in a fairly wide range of temperatures, including cold. The Ni-MH technology has a higher energy density than nickel cadmium and in particular a very favourable environmental balance. High power performance and a long useful life in wide ranges of temperature afford Ni-MH technology high potential. The two main differences between Ni-Cd and Ni-MH is Ni-Cd batteries are best used in high rate discharge or charging applications and Ni-MH is best used in low rate applications as these batteries have a much longer run time.
