Discharge/charge cycles before the capacity drops to 80% when replacement is. Rising resistance with age is common with nickel-based and early Li-ion batteries. Most battery testers only measure voltage and internal resistance;. A practical electrical power source which is a linear electric circuit may, according to Thévenin's theorem, be represented as an ideal voltage source in series with an impedance. This impedance is termed the internal resistance of the source. When the power source delivers current, the measured voltage output is.
