Bhatiri re18650 imhando ye lithium-ion rechargeable bhatiri ine saizi yakajairwa ye18mm ne65mm. Inowanzoshandiswa mumidziyo yakawanda yemagetsi yakadai semalaptops, tochi, uye mota dzemagetsi. Bhatiri re18650 rine simba repamusoro uye rinogona kuchengetedza huwandu hwesimba muhukuru hudiki, zvichiita kuti ive sarudzo yakakurumbira yemidziyo inotakurika. Iyo inozivikanwa zvakare nehupenyu hwayo hurefu hwekutenderera, zvinoreva kuti inogona kubhadhariswa uye kuburitswa kakawanda isati yada kutsiviwa. Zvisinei, zvakakosha kuziva kuti bhatiri re18650 rinofanira kushandiswa nekuchenjerera uye kubatwa zvakanaka kudzivirira njodzi dzekuchengetedza dzakadai sekuputika uye moto.

Bhatiri re18650 icylindrical lithium-ion bhatiri ine dhayamita ye18mm uye kureba kwe65mm. Yakatanga kuunzwa naSony muna 1991 uye yave imwe yeanonyanya kushandiswa mabhatiri ekuchajiswa mumidziyo yakawanda yemagetsi, kusanganisira malaptop, maturusi emagetsi, uye mota dzemagetsi. Kuenzaniswa nedzimwe mhando dzemabhatiri, bhatiri re18650 rine simba repamusoro-soro, hupenyu hurefu hwekutenderera, uye kuita zvirinani mukutonhora kwechando. Iyo inozivikanwa zvakare nekugona kwayo kuendesa yakakwira discharge currents, zvichiita kuti ive sarudzo yakakurumbira yezvishandiso zvinoda kuburitsa simba repamusoro. Zvisinei, zvakakosha kubata bhatiri re18650 zvakanaka uye kudzivisa kudarika kana kupisa, sezvo izvi zvinogona kukonzera njodzi dzekuchengetedza.
