ABSTRACT
This study explored the possibility of using a combination of spoiled Kamias, Banana, and Pineapple (KaBaPine) fruits as an alternative source of power. It aimed to make dry cell contraction with KaBaPine fruits as the electrolyte and to be able to generate a substantial amount of potential difference from it. The combination of fruits was pretested and yielded the potential difference of about 0.80 Volts. Factors that may affect potential difference, acid and base and the rate of the fruit’s spoilage, were tested on the KaBaPine combination. The test results revealed that there was no significant difference between the voltage produced by pure KaBaPine and those produced by KaBaPine combined with basic or acidic solutions. Using zinc containers of old size C dry cell the contraptions were constructed. The KaBaPine was placed inside as the new electrolyte. The copper wire was soldered to the base of the cap and was used to seal the cell to replace the carbon rod in common dry cells. The improvised KaBaPine cells were connected in series and were able to generate enough amount of voltage that could compete with the commercially available ones.
