Singa bbaatule mu mmotoka ey’amasannyalaze ennongooseemu eba nnyimpi-ekisulo ky’obulamu-okutwalira awamu, okutwalira awamu emala emyaka 2-3. Bw’eba bbaatule ya lithium iron phosphate, obulamu bw’enzikiriziganya buba bwa myaka 7-8. Obulamu bwa bbaatule busobola okutuuka ku 1,000-2,000 ezifuluma. Nga tufuddeyo ku mutendera gwa charge and discharge cycle, emirundi 365 mu mwaka, .
Mu ndowooza, bbaatule esobola okumala emyaka 3-6. Obulamu bwa bbaatule wano butegeeza ddi obusobozi bwa bbaatule bwe bukendedde okutuuka ku bitundu 70% ku busobozi bwayo obw’olubereberye.
Obulamu bwa bbaatule y’emmotoka ey’amasannyalaze businziira ku nkozesa, okutwalira awamu emyaka nga 3, era kiyinza okusukka emyaka 5. Mu kiseera kya ggaranti eky’emyaka etaano-, diiru ejja kukebera bulijjo bbaatule era ekuwa amagezi okukyusibwa singa wabaawo modulo yonna ezuulibwa ng’erina omulimu ogw’okukendeeza.
Olw’okuba mmotoka ez’amasannyalaze ennongoofu zibeera battery-zirina amaanyi, zirina okuvunda kwa bbaatule, ekivaamu okuwangaala okumpi, okutwalira awamu nga emyaka etaano ku mukaaga. Kino kituufu naddala ku mmotoka empya ez’amaanyi ezirina enjawulo ennyimpi n’ebitundu ebikaddiwa, ebiyinza okuba n’obulamu bwa bbaatule obumpi.
