Ubushobozi nubunini bwamashanyarazi bateri yizuba ishobora kubika, ipimwa mumasaha ya kilowatt (kilowat). Bateri nyinshi zo murugo zashizweho kugirango zibe "stackable," bivuze ko ushobora gushyiramo bateri nyinshi hamwe na sisitemu yawe-yongeyeho-kubika kugirango ubone ubushobozi bwinyongera.
Mugihe ubushobozi bukubwira uko bateri yawe nini, ntabwo ikubwira amashanyarazi bateri ishobora gutanga mugihe runaka. Kugirango ubone ishusho yuzuye, ugomba no gusuzuma igipimo cya bateri. Mu rwego rwa bateri yizuba, igipimo cyingufu ni umubare w'amashanyarazi bateri ishobora gutanga icyarimwe. Ipimwa muri kilowatts (kilowati).
Batare ifite ubushobozi buhanitse kandi ifite ingufu nkeya yatanga amashanyarazi make (bihagije kugirango akoreshe ibikoresho bike byingenzi) mugihe kirekire. Batare ifite ubushobozi buke hamwe nimbaraga nyinshi zishobora kuyobora urugo rwawe rwose, ariko kumasaha make.
