Iibhetri zealkaline luhlobo lwebhetri olulahlwayo elisebenzisa i-alkaline electrolyte, eqhelekileyo i-potassium hydroxide, ukunika amandla izixhobo zombane ezincinci ezifana nolawulo olukude, iithoyi, kunye nezibane. Baziwa ngobomi babo beshelufu obude kunye nokusebenza okuthembekileyo, okubenza babe lukhetho oludumileyo kuluhlu olubanzi lwee-electronics zabathengi. Xa ibhetri isetyenzisiwe, ukusabela kweekhemikhali kwenzeka phakathi kwe-zinc anode kunye ne-manganese dioxide cathode, ukuvelisa amandla ombane.

Iibhetri zealkaline zidla ngokusetyenziswa kuluhlu olubanzi lwezixhobo zemihla ngemihla, njengokulawula kude, iithotshi, izinto zokudlala, kunye nezixhobo zombane eziphathwayo. Ziyaziwa ngokubonelela ngamandla athembekileyo kwaye ziphila ixesha elide, okwenza ukuba zilungele izicelo ezahlukeneyo. Nangona kunjalo, kubalulekile ukuqaphela ukuba iibhetri zealkaline kufuneka zilahlwe ngokufanelekileyo ukunciphisa impembelelo yazo yokusingqongileyo kuba ezinye iibhetri zealkaline zisaqulethe izinto ezinobungozi, ezifana nemekyuri, iintsimbi ezinzima njengecadmium kunye nelothe. Xa ezi bhetri zingalahlwanga kakuhle, ezi zinto zinokungena emhlabeni nasemanzini, zibangele umonakalo kwi-ecosystem. Kubalulekile ukuphinda kusetyenziswe iibhetri zealkaline ukunqanda ukukhutshwa kwezi zinto ziyingozi kwimo engqongileyo.

Kungenxa yoko le nto ukusebenzisa iibhetri ze-alkaline ezingenayo imekyuri kunokufaka isandla ekukhuselweni kwendalo. I-Mercury yinto enetyhefu enokuthi ibe nemiphumo emibi kwindalo kunye nempilo yabantu. Ngokukhetha iibhetri nge-0% ye-mercury, unokunceda ukunciphisa impembelelo enokubakho engalunganga yezinto ezinobungozi kwindalo. Ukongeza, kubalulekile ukulahla ngokufanelekileyo kunye nokuphinda usebenzise iibhetri ukunciphisa ngakumbi impembelelo yokusingqongileyo. Ukukhethaiibhetri zealkaline ezingenamekhyurilinyathelo elilungileyo elibhekiselele kukhuseleko lokusingqongileyo.
Ngelixa ukurisayikilisha iibhetri zealkaline kuluncedo, kukwabalulekile ukukhangela ezinye iindlela, iinketho ezihambelana nokusingqongileyo, ezinjengokusebenzisa iibhetri ezinokutshajwa kwakhona (Umzekelo:AA/AAA NiMH Iibhetri ezitshajekayo,18650 lithium-ion ibhetri etshajwayo) okanye ukufuna iimveliso ezinemithombo yamandla ehlala ixesha elide (Umzekelo:umthamo ophezulu AAA ibhetri yealkaline,umthamo ophezulu AA ibhetri yealkaline). Ekugqibeleni, indibaniselwano yokulahla uxanduva kunye nokutshintshela kwezinye iindlela ezizinzileyo kunokufaka isandla kukhuseleko lokusingqongileyo.
