Ol i save yusim ol 'valve-regulated lead-acid' bateri (VRLA) insait long ol UPS insait long wanpela pak. Ol bren em Tangshan, Panasonic, na Rich, na ol narapela, na DC yunit voltej em 12V. Bateri em i wanpela samting bilong putim lektrik eneji we i save sasim na rausim na senisim kemikel eneji i go long lektrik eneji. Ol 'lead-acid' bateri i gat Pb (negative electrode) na PbO2 (positive electrode) we ol i putim insait long 'dilute sulfuric acid' (H2SO4), na olgeta wan wan 'monomer' i gat 2V 'electromotive force'.
