Maxwell Ultra Capacitors are used as backup power supply in various applications such as UPS systems, emergency lighting with low voltage, solid state drivers (SSD) and remote systems by means of their capabilities of long operating lifetime, requiring zero or minimum maintenance and operating at temperature levels between -40 C to +65 C.

Kinetic energy during regenerative braking is stored at batteries or ultra capacitors to be used later on. Operating performance of these batteries are critically affected by low temperatures due to their low power density. Ultra capacitors can work stand-alone by means of being able to switch more than a million times, capability of being charge-discharge quickly, high efficiency and being environment friendly. They increase battery lifetimes and productivity and optimize system cost and dimensions when cooperated with batteries.

Ultra capacitors are used in various application fields such as consumer electronics, hybrid vehicles and renewable energy resources by means of having various dimensions and modular structures, being able to switch more than a million times, capability of being charge-discharge quickly, high efficiency and being environment friendly.

Batteries are not always the best choice as energy storing systems. It takes hours to recharge even though they have high energy density. In comparison, ultra capacitors can recharge in seconds or minutes even though they have less energy density. They are used in various application fields such as electrical house appliances, torch, medical and personal care devices, kitchen appliances, industrial imaging devices, road signs with solar energy supply, retail transaction devices and emergency communication devices with solar energy source along road by means of being able to switch more than a million times, high efficiency and being environment friendly.

Batteries do not provide the power required to start up the engine in case of cold weather conditions or if multiple electrical components are operating actively at the same time or when they get old. In comparison, ultra capacitors provide the power, required to start up the engine if multiple electrical components are operating actively at the same time, by means of their high power density at low temperatures.
