The efficiency of any electric cell or battery is very important. To keep it in mind, the coulombic efficiency, voltaic efficiency and energy efficiency have been studied. It was found that the coulombic efficiency data illustrated that this efficiency was higher comparing to other efficiencies may be the absence of salt bridge or separator between the electrodes. However, the highest efficiency was obtained for 40% PKL (Pathor Kuchi Leaf) sap with 5% secondary salt in 55% aqueous solution, which implies that the concentration of PKL juice can play an important role regarding efficiency. It was also found that the average energy efficiency was 97.43%, and it was also found that the average voltaic efficiency was 57.29%. Temperature effect of the PKL electrochemical cell has also been studied. It is found that the ideal temperature for this PKL electrochemical cell is room temperature and it is from 20 to 40 °C. But, it is also usable at a lower temperature from 5 to 60 °C as like as other standard cells. Most of the results have been tabulated and graphically discussed.
