Battery Test Methods
Table 1: Battery test methods for common battery chemistries. Lead acid and Li-ion share communalities by keeping low resistance under normal condition; nickel-based and primary batteries reveal end-of-life by elevated internal resistance. At a charge efficiency of 99 percent, Li-ion is best suited for digital battery estimation.
