I-Outlook yemakethe yebhethri elisindayo
Imakethe yomhlaba wonke yebhethri ye-zinc carbon ikhula kakhulu futhi izokhula kakhulu eminyakeni embalwa ezayo.Ukusebenzisana kwe-electrochemical phakathi kwe-zinc ne-manganese dioxide kukhiqiza amandla kagesi aqondile ebhethri le-zinc-carbon, okuyibhethri eyisisekelo yeseli eyomile (MnO2).Funda kabanzi -
Yini okufanele (futhi okungafanele uyenze) uma usebenzisa amabhethri?
Amabhethri asehambe ibanga elide.Ngokuhamba kweminyaka, ubuchwepheshe obuthuthukisiwe kanye nomklamo ongcono kubenze umthombo wamandla ophephe kakhulu futhi osebenzayo.Kodwa-ke, azinangozi ngokuphelele uma ziphathwa ngokungalungile.Ukwazi ukuthi (akumele) wenzeni ngamabhethri ngakho-ke kuyisinyathelo esibalulekile esibheke kubhethri elilungile...Funda kabanzi -
