Ingorane z'ubuhinga bw'ibikoresho vy'ubuhinga bwa none

Ingorane iri ku modoka zikoresha umuyagankuba ni uko amabateri abika inguvu nke cane ku buremere bw’ibintu. Ikindi kandi, kubera ko amabateri y’imodoka akoresha umuyagankuba azimvye kandi ubutunzi bw’urugero ntiburashikwako, birazimvye cane kugura. Naho ku bijanye n’ibiciro vyo gukoresha, bimwe bizimvye kuruta imodoka, mu gihe ibindi ari kimwe gusa - ivya gatatu ku giciro. Ivyo biva ahanini ku bici- ro vy’amavuta y’amabati be n’ibiciro vy’amavuta n’amashanyarazi vyo mu karere. Ubu, ubushobozi bwa bateri ntibuhagije, kandi urutonde ntiruhagije ku bijanye n'ikoreshwa ryose{5}}.
