Mabatire a alkaline ndi mtundu wa batire lotayidwa lomwe limagwiritsa ntchito alkaline electrolyte, nthawi zambiri potassium hydroxide, kupangira mphamvu zamagetsi zazing'ono monga zowongolera zakutali, zoseweretsa, ndi tochi.Amadziwika ndi moyo wawo wautali wautali komanso ntchito zodalirika, zomwe zimawapanga kukhala chisankho chodziwika bwino chamagetsi ambiri ogula.Batire ikagwiritsidwa ntchito, zimachitika pakati pa anode ya zinc ndi manganese dioxide cathode, kupanga mphamvu zamagetsi.

Mabatire a alkaline amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana za tsiku ndi tsiku, monga zowongolera zakutali, tochi, zoseweretsa, ndi zida zamagetsi zonyamula.Amadziwika kuti amapereka mphamvu zodalirika komanso amakhala ndi nthawi yayitali, kuwapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana.Komabe, ndikofunikira kudziwa kuti mabatire a alkaline amayenera kutayidwa moyenera kuti achepetse kuwonongeka kwa chilengedwe chifukwa mabatire ena amchere amakhalabe ndi zinthu zowopsa, monga mercury, zitsulo zolemera monga cadmium ndi lead.Mabatire amenewa akapanda kutayidwa bwino, zinthu zimenezi zimatha kulowa m’nthaka ndi m’madzi, n’kumawononga chilengedwe.Ndikofunika kukonzanso mabatire a alkaline kuti zinthu zovulazazi zisamatuluke m'chilengedwe.

Ndicho chifukwa chake kugwiritsa ntchito mabatire amchere omwe alibe mercury angathandize kuteteza chilengedwe.Mercury ndi mankhwala oopsa omwe amatha kuwononga chilengedwe komanso thanzi la anthu.Posankha mabatire okhala ndi 0% mercury, mutha kuthandizira kuchepetsa zomwe zingawononge chilengedwe.Kuonjezera apo, ndikofunika kutaya ndi kubwezeretsa mabatire moyenera kuti muchepetse kuwonongeka kwa chilengedwe.Kusankhamabatire a alkaline opanda mercuryndi njira yabwino yotetezera chilengedwe.
Ngakhale kubwezanso mabatire a alkaline kuli kopindulitsa, ndikofunikiranso kufufuza njira zina, zokonda zachilengedwe, monga kugwiritsa ntchito mabatire otha kuchajwanso (Mwachitsanzo:AA/AAA NiMH Mabatire Othachanso,18650 lithiamu-ion rechargeable batire) kapena kufunafuna zinthu zokhala ndi mphamvu zokhalitsa (Mwachitsanzo:mkulu mphamvu AAA alkaline batire,mkulu mphamvu AA alkaline batire).Pamapeto pake, kuphatikizika kwa kutayidwa koyenera ndikusintha njira zina zokhazikika kungathandize kuteteza chilengedwe.
