Mabatire amabwera m'makhemistri ndi mitundu yosiyanasiyana, ndipo njira ziwiri zodziwika bwino zowonjezedwanso kukhala batire ya Li-ion (lithium-ion) ndi batire ya NiMH (nickel-metal hydride).Ngakhale amagawana zinthu zofanana, batri ya Li-ion ndi batri ya NiMH ali ndi kusiyana kwakukulu komwe kumawapangitsa kukhala oyenera ntchito zosiyanasiyana.Kumvetsetsa kusiyana kumeneku kungakuthandizeni kusankha teknoloji yoyenera ya batri.
Kuchuluka kwa Mphamvu: Chinthu chofunika kwambiri pakusankha batire ndi kuchuluka kwa mphamvu, kuyesedwa mu maola a watt pa kilogalamu (Wh/kg).Mabatire a lithiamu amapereka mphamvu zambiri kuposa mabatire a NiMH.Mwachitsanzo, batire ya lithiamu-ion imapereka mozungulira 150-250 Wh/kg, poyerekeza ndi kuzungulira 60-120 Wh/kg ya NiMH.Izi zikutanthauza kuti mabatire a lithiamu amatha kunyamula mphamvu zambiri pamalo opepuka komanso ang'onoang'ono.Izi zimapangitsa mabatire a lithiamu kukhala abwino kupatsa mphamvu zida zamagetsi zamagetsi kapena magalimoto amagetsi.Mabatire a NiMH ndiwochulukirachulukira koma akadali othandiza pamapulogalamu pomwe kukula kochepa sikuli kofunikira.
Kutha Kulipira: Kuphatikiza pa kuchulukitsitsa kwamphamvu, mabatire a lithiamu-ion amaperekanso mphamvu yokulirapo kuposa mabatire a NiMH, omwe amawerengedwa pa 1500-3000 mAh ya lithiamu vs. 1000-3000 mAh ya NiMH.Kuchuluka kwamphamvu kumatanthawuza kuti mabatire a lithiamu amatha kugwiritsa ntchito zida nthawi yayitali pamtengo umodzi poyerekeza ndi NiMH.Komabe, mabatire a NiMH amaperekabe nthawi yayitali yokwanira yamagetsi ambiri ogula ndi zida zamagetsi.
Mtengo: Pankhani ya mtengo wakutsogolo, mabatire a NiMH amakhala otsika mtengo kuposa mabatire a lithiamu-ion.Komabe, mabatire a lithiamu ali ndi mphamvu zowonjezera mphamvu, kotero mumafunika maselo a lithiamu ochepa kuti agwiritse ntchito chipangizo, chomwe chimachepetsa ndalama.Mabatire a lithiamu amakhalanso ndi moyo wautali, ndipo ena amasunga mpaka 80% ya mphamvu zawo pambuyo pozungulira 500.Mabatire a NiMH nthawi zambiri amatha kuzungulira 200-300 asanatsike mpaka 70%.Chifukwa chake, ngakhale NiMH ikhoza kukhala ndi mtengo wotsika woyambira, lithiamu ikhoza kukhala yotsika mtengo pakapita nthawi.
Kulipira: Kusiyana kwakukulu pakulipiritsa kwa mitundu iwiri ya batri ndikuti mabatire a lithiamu-ion alibe mphamvu ya kukumbukira, mosiyana ndi mabatire a NiMH.Izi zikutanthauza kuti mabatire a lithiamu amatha kutulutsidwa pang'ono ndikuwonjezeredwa kambirimbiri popanda kusokoneza magwiridwe antchito kapena moyo wa batri.Ndi NiMH, ndibwino kuti mutulutse ndikuwonjezeranso batire kuti mupewe kukumbukira kukumbukira, zomwe zingachepetse mphamvu pakapita nthawi.Mabatire a lithiamu amakhalanso mwachangu, nthawi zambiri m'maola 2 mpaka 5, motsutsana ndi maola 3 mpaka 7 pamabatire ambiri a NiMH.
Environmental Impact: Ponena za ubwenzi wa chilengedwe, NiMH ili ndi ubwino wina kuposa lithiamu.Mabatire a NiMH ali ndi zinthu zapoizoni zochepa chabe ndipo alibe zitsulo zolemera, zomwe zimawapangitsa kuti asawononge chilengedwe.Amatha kubwezeredwanso kwathunthu.Mabatire a lithiamu, komano, amakhala ndi zitsulo zolemera zapoizoni monga zitsulo za lithiamu, cobalt, ndi faifi tambala, zimabweretsa chiwopsezo cha kuphulika ngati atenthedwa, ndipo pakadali pano ali ndi njira zochepa zobwezeretsanso.Komabe, mabatire a lithiamu akukhala okhazikika pamene matekinoloje atsopano a batri akutuluka.
