This study describes an optimized method for charging lead-acid batteries that are widely used in small uninterrupted power supplies. Research on charging lead-acid batteries effectively, safely, and in an environmentally friendly means has been ongoing for many years. Uninterrupted power supply (UPS) devices are conventionally used in personal computers and commercial equipment. An ideal battery charging technique usually involves fast charging, an efficient energy storage rate, and prolonged battery lifetime. This study adopted the pulse charging technique to achieve the aforementioned goals. Various pulse charging parameters, duty cycles, frequencies, and average values of pulses were applied in experiments. The experimental results indicate that an optimum-charging mode, with efficiency as high as 85.6% and charging time as short as two hours, can be achieved by applying appropriate parameters.
