Zochitika pakusankha kwa batrinyali yakumutu

Patha zaka 20 kuchokera pamene ndinatuluka panja mu 1998 ndikugula chikwama choyamba chokwera mapiri cha vaude70.M'zaka 20 izi, ndagwiritsa ntchito mitundu yopitilira 100 ya nyali zakumutu.Kuyambira pogula zinthu zomalizidwa mpaka kudzipangira tokha, ndili ndi zofunika zosiyanasiyana.Pomaliza, ndimangosunga ma tochi opitilira khumi ndi awiri.Tsopano ndikungolankhula za zomwe ndakumana nazo pakusankha batri.
Nyali zam'mutu zili ndi zofunika kusankha mabatire mosiyanasiyana malinga ndi malo ogwirira ntchito.
Mwachitsanzo, kungoyenda kapena kuthamanga m'misewu ya m'tawuni ndi yakumidzi, nthawi yogwiritsira ntchito siili yaitali, ndipo kutentha kozungulira sikudzakhala kochepa kwambiri.Popeza batire ikhoza kugulidwa ndikusinthidwa nthawi iliyonse, mabatire a AAA, AA ndi alkaline carbon angagwiritsidwe ntchito.Chifukwa simalo ovuta, batire imatha kusinthidwa ndikuwonjezeredwa nthawi iliyonse.Pofuna kupepuka, anthu ambiri amasankha nyali za 3AAA.

M'nyengo yozizira, mabatire otsika amatha kusankha mabatire a lithiamu kapena mabatire a nickel metal hydride.Pakati pawo, batire yotsika ya Ni MH imatha kugwiritsidwa ntchito paminus 40 degrees!Komabe, mphamvu ya batire yotsika kwambiri ya Ni MH ndiyotsika.
Ngati mukufuna kutenga msewu wamapiri, 100-200 lumens ndiyofunikira.Kupanda kutero, kumakhala kovuta kuwona pamwamba pa msewu bwino.Msewu wa nkhalango, makamaka msewu wokhala ndi masamba ovunda kwambiri komanso wonyowa pang'ono, nthawi zambiri ndimagwiritsa ntchito 350-400 lumens pakuwunikira, komanso ndimagwiritsa ntchito pafupifupi 600 lumens zovuta komanso zovuta kuyenda.Kupanda kutero, kugwiritsa ntchito ma lumens pafupifupi 150 pakuwunikira kumangolowa m'matope nthawi zonse.

Chifukwa cha kufunikira kowunikira, kuti mutsimikizire mphamvu yowunikira, pali zofunikira pa batire la nyali.Chifukwa chake, kuti muwonetsetse kufunikira kowunikira, tikulimbikitsidwa kugwiritsa ntchito 3AA kapena 4AA kuti mupereke zofunikira zokwanira.Ponena za 3AAA, ndi bwino kuphulika 200 lumens mu nthawi yochepa, ndipo nthawi yowunikira nthawi zonse ya 200 lumens mu theka la ola silingaperekedwe, ndipo kuwalako kudzatsika kwambiri.Kupatula apo, kuchuluka kwa batri kumatsimikizira.

Pankhani ya otsika kutentha mphamvu posungira ntchito, mabatire zamchere zalephera kotheratu, nickel hydrogen mabatire kwenikweni ofanana lithiamu mabatire, ndi mphamvu - 30 madigiri zosakwana 50%.

Ngati kuli kovuta kupeza magetsi panja kwa nthawi yayitali, tikulimbikitsidwa kugwiritsa ntchito 18650 lithiamu batire yoyendetsedwa ndi nyali yakumutu.
