Incazelo yesichazamazwi yegama elithi "Ibhethri" isho iyunithi eyodwa noma iseli yebhethri ekhiqiza amandla kagesi ngokusabela kwamakhemikhali. Ngokuvamile iqukethe i-anode, i-cathode, ne-electrolyte, evumela ukugeleza kwama-ion phakathi kwe-anode ne-cathode ukukhiqiza okwamanje. Ngokusetshenziswa okuvamile, "Ibhethri" ingase futhi ibhekisele kusilinda, ibhethri le-alkaline elingu-1.5-volt elivame ukusetshenziswa kumishini kagesi yasendlini.
