Portability in devices is ever increasing as the technology nowadays is moving forward to be in line with human lifestyles which prefer multitasking in daily routine. As the portable devices are consuming battery as a main source of electricity, battery with long lasting performance is preferable. Battery contains heavy metals such as mercury, lead, nickel, zinc and manganese which are hazardous to enviroument and humankind. Battery with short runtime will need for a frequent replacement which leads to more heavy metals waste. Eventually, a new industrial revolution of nanotechnology has a great impact on the development of ultracapacitor. Ultracapacitor has been an interest in electrical and electronic field as its capability has an obvious improvement which can contribute for further development of electrical devices. Therefore, The objective of this project is to study the effects of ultracapacitor on the battery performance in terms of its ability to sustain voltage of the battery over time and provide enough current to the load for a longer time Throughout this project, the circuit of standalone battery, battery in parallel with ultracapacitor and battery in series with ultracapacitor are tested. Ultracapacitors used with the capacitance of 0.5F, l.OF, 1.5F and 2.0F give the different voltage and current at the load over time. The results in this project will be a comparison of graph of voltage and current for each circuit arrangement over the time. In conclusion, ultracapacitor with the capacitance 0.5F connected in parallel with battery give the best improvement to the battery performance. However, the larger capacitance value of ultracapacitor is not a factor which will give a better performance of the battery
