Tisisiteme ta mphakelo wa gezi leti nga kavanyetiwiki (UPS) i ta nkoka swinene eku hlayiseni ka gezi leri yaka emahlweni eka tisisiteme ta nkoka hi nkarhi wa ku yimisiwa ka gezi. Exikarhi ka tisisiteme leti ku ni tibetiri leti hlayisaka matimba lama lavekaka. Ku twisisa tinxaka to hambana ta tibetiri ta UPS i swa nkoka swinene eku hlawuleni ka ndlela leyinene ngopfu .

Loko swi ta eka ku hlawula betri leyi faneleke eka swilaveko swa wena, ku twisisa ku hambana exikarhi ka tibetiri ta lithium, ngopfu-ngopfu tibetiri ta LifePo4, na lead-acid i swa nkoka swinene. Swihlawulekisi swa tona leswi hambaneke swi endla leswaku ti faneleka eka swiyimo swo hambana. Ku pimanisiwa ka nkoka loku kurisiweke na cycle lifelithi .

Tibetiri ta lead-acid ti vile ribye ra xisekelo eka thekinoloji yo hlayisa eneji ku sukela loko ti tumbuluxiwile exikarhi ka lembe xidzana ra vu-19. Swihlovo leswi swa gezi leswi tshembekaka swi tirhisiwa ngopfu eka switirhisiwa swo hambana. Ku twisisa ndlela leyi tibetiri ta lead-acid ti tirhaka ha yona i swa nkoka eka ku antswisa matirhelo ya tona na ku andlala L ya tona .

Battery vulcanization, leyi tlhelaka yi tiviwa tanihi sulfation, i mhaka leyi tolovelekeke leyi khumbaka tibetiri ta lead-acid, leswi yisaka eka ku hunguteka ka matirhelo na vutomi lebyi pfuxetiweke. Ku twisisa swivangelo na ku tirhisa magoza yo sivela i swa nkoka swinene eka ku hlayisa rihanyo na vutomi byo leha bya tibetiri ta lead-acid.Leswi I .

Ku khoma ti nuances ta ku lwisana ka le ndzeni na impedance, i swa nkoka swinene ku lemuka leswaku impedance yi fambelana na AC (alternating current), kasi ku lwisana ka le ndzeni swi fambelanisiwa ngopfu na DC (direct current).
