Dispela OCV (Open Circuit Voltage) na IR (Internal Resistance) Testa em i wanpela gutpela instramen we ol i wokim bilong sekim ol bateri sel hariap na i no inap bagarapim. Em i save mekim tupela bikpela wok skelim: 'static Open Circuit Voltage' bilong skelim 'state' bilong 'charge' na helt bilong sel, na 'DC Internal Resistance', we planti taim ol i save yusim 'DC load method', bilong skelim pawa inap na koneksen integriti.
Dispela 'bench-top o insait long-lain testa i gat bikpela spit (planti taim insait long sampela seken), 'milivolt-level voltage accuracy, na 'milliohm-level resistance resolution', dispela 'bench-top' o 'in-lain testa em i bikpela samting long 100% inspeksen insait long ol prodaksen lain. Dispela OCV sel testing masin i save luksave gut long ol sel we i no wok gut wantaim ol 'voltage abnormalities' o bikpela intanel resistens pastaim long ol i wokim o gredim, na dispela i save mekim ol 'batch' i stap wankain. Ol stebol, ripitim mesamen na data logging kapasiti bilong en em i bikpela samting long gutpela wok bilong skelim ol bateri na gutpela wok bilong bungim ol paket insait long ol 'manufacturing' na 'quality control laboratories'.
