Lapho ukhetha ibhethri elifanele kakhulu izidingo zakho, kunezici ezimbalwa ezibalulekile okufanele uzicabangele. Nazi ezinye izinyathelo zokukusiza wenze isinqumo unolwazi:

1. Thola izidingo zakho zamandla: Bala amandla noma izidingo zamandla zocingo noma uhlelo olidingayo ibhethri. Cabangela izici ezifana ne-voltage, yamanje, nesikhathi sokusebenza.
2. Qonda izinhlobo ezahlukene zamabhethri: Kunezinhlobo ezahlukene zamabhethri, okuhlanganisa ne-alkaline (isb:1.5v AA LR6 Ibhethri le-alkaline, 1.5vIbhethri ye-alkaline ye-AAA LR03, Ibhethri ye-alkaline engu-1.5v LR14C,1.5V LR20 D ibhethri le-alkaline, 6LR61 9V ibhethri le-alkaline, 12V MN21 23A ibhethri le-alkaline,12V MN27 27A ibhethri le-alkaline), i-lithium-ion (isb:18650 Ibhethri ye-3.7V Lithium Ion Eshajwa kabusha, 16340 Ibhethri le-lithium-ion elishajekayo, 32700 Ibhethri elishajekayo i-lithium-ionnjll.), i-lead-acid,AA AAA nickel-metal hydride Ibhethri(isb:AAA nickel-metal hydride Ibhethri, I-AA nickel-metal hydrideIbhethri, Iphakethe lebhethri le-nickel-metal hydride), futhi nokuningi. Uhlobo ngalunye lunezici ezihlukile futhi lufanele izinhlelo zokusebenza ezahlukene.
3. Cabanga ngezimo zemvelo: Cabanga ngezimo zemvelo lapho ibhethri izosetshenziswa khona. Amanye amabhethri asebenza kangcono emazingeni okushisa aphezulu noma kunomswakama ophezulu (Iphakethe lebhethri le-nickel-metal hydride, 18650 Ibhethri ye-3.7V Lithium Ion Eshajwa kabusha), ngakho-ke kubalulekile ukukhetha ibhethri elikwazi ukuphatha izimo zemvelo zohlelo lwakho lokusebenza.
4. Isisindo nosayizi: Uma ibhethri izosetshenziswa kudivayisi ephathekayo, cabangela isisindo nosayizi webhethri ukuze uqinisekise ukuthi iyazifanela izidingo zakho.
5. Izindleko: Cabangela ibhajethi yakho kanye nezindleko zesikhathi eside zebhethri, okuhlanganisa izici ezifana nobude besikhathi sokuphila kanye nezimfuneko zokunakekelwa (isb.I-1.5v AA Ephindwe Kabili A Uhlobo C lwe-USB Amabhethri e-Li-ion Aphinde Ashajwe).
6. Ukuphepha nokuthembeka: Qinisekisa ukuthi ibhethri olikhethayo liphephile futhi lithembekile kuhlelo lwakho lokusebenza oluthile. Bheka amabhrendi ahloniphekile futhi uhlole izitifiketi ezifanele noma ukuthotshelwa kwamazinga.
7. Ukushajwa kabusha uma kuqhathaniswa nokungashajwa kabusha: Nquma ukuthi udinga ibhethri elishajekayo noma elingashajeki ngokusekelwe kuphethini yakho yokusetshenziswa nokuthi ingabe ukushajwa okuvamile kuyenzeka yini ohlelweni lwakho lokusebenza.
8. Funa iseluleko sochwepheshe: Uma ungaqiniseki ngokuthi iyiphi ibhethri elilungele izidingo zakho, cabanga ngokufuna iseluleko kuchwepheshe webhethri noma umkhiqizi.

Ngokucabangela lezi zici, ungenza isinqumo unolwazi ngebhethri elifanele kakhulu lezidingo zakho ezithile.
