High current testing of batteries

Different types of commercial batteries were tested in a high-current mode to determine which is the best in portable pulsed power applications. The testing of the batteries was performed in two regimes: short time regime (one second) and long time regime (one hundred seconds). Alkaline, carbon, lithium, lithium ion, lead acid and nickel cadmium batteries of different dimensions have been tested to determine the maximum usable power for short and long time modes. The resistance of the load was varied from 1 /spl Omega/ to 22 m/spl Omega/. Current-voltage characteristics are presented for sixteen different types of batteries. Data are given for maximum power per unit of weight and per unit of volume.
